- You can simply make a generator, using a car alternator. To get a high voltage output, use a step-up transformer or if output is rectified, you can also use power inverter. Thanks for watching, please subscribe, rate and comment ;)
do you have any videos in more debth of building this ? I think I would love to build one but, I am a little oveerwheled with it still !
The output from the alternator is 12 volt D.C correct?? My understanding is only A.C can be put on a transformer to increase or decrease the voltage??????? Or no???????
I've been thinking about building building something similar if not the same. I Want to take a car alternator driven with a 12 volt motor which will charge 1 or 2 car batteries wired in series then off of that get an invertor of 120 volt, which could power a small refrigerator or make a couple of them to power a few essential items. I'd like to do it to take it camping with me. Cuz its basically a portable power station, that could last for quite a while.
Any input or feedback would be appreciated
If we are talking "complete" alternator, including rectifier, then yes, you'll get DC out of such device, but here, I'm bypassing the diodes, so I get AC. Alternator gets its name from "alternating" current, so it's an AC machine. Coupling it with rectifier, will give you unregulated DC, so, by adding a regulator, you get regulated DC (which is still just a pulsating DC, but battery smoothes it out, so you get smooth, regulated DC. Why would you drive an alternator with a 12V motor to charge 12V batteries, when you could charge your batteries with 12V source directly, avoiding energy losses?
I have a pretty simple question let's say you managed to get the alternator set up with proper gears on the rotor shaft so that a hydro set up would give it ideal Rpms,
How much induction volts/Amos/watts is needed to properly induce the magnet field and produce a decent output worthy of the transformer set up
With the help of car alternator can we make a wind turbine and recharge a 12v battery ?
Of course! Thanks for watching!
Yacht motors tend to run at 1800-2500 RPM.
The alternator output is rectified to charge the battery at 13.7v and this charges a 12v battery of which you can run an inverter to power your laptop.
This is inefficient because you rectify then invert, when you already have a sinusoidal wave present, albeit at the wrong frequency and voltage.
If you wanted to get a 230-240v 50Hz or 110-120v 60Hz output off an alternator running off the drive (prop) shaft, how would you do it?
Would the regulator automatically maintain the excitation current at the right levels to control the output voltage and allow you to simply transform the voltage (12:120, 12:240, or two parallel 12s:120s series as you illustrated)?
What about the frequency change? Would you have to use some sort of gearing (30x best, 50 worst!), or do you see some way of using circuits to change the frequency? (Could this frequency change be handled by the regulator?)
Would re-winding the wires in the alternator help with f-change, or just V-change?
I might have been wrong when I said the existing regulator could maintain the proper excitation current, since you're connecting the transformer directly to the windings and therefore bypass the regulator, but there might still be some regulation happening (honestly I didn't try it with original regulator, since it was dead). But you could monitor the output voltage on from the transformer and adjust the rotor current accordingly. I believe, this could be easily achievable with simple electronic feedback circuit (there are lots online, that could be used) and the circuit would tell a MOSFET whether to turn the excitation current on or off, based on the measured output voltage. You could change the frequency by changing the number of poles (removing some coils from the rotor) or simply, by lowering the rotational speed - with this, you'd probably lose quite a lot of efficiency, since alternators usually run most efficiently at around 5 or 6000rpm (about double of what I was running it at, here) - that's for common car alternators, you might have something different on your yacht, perhaps, but not necessarily. A good start would be to measure the frequency (directly on the windings). What would you need this setup for, also makes a huge difference, for example; you can't run induction motors at proper speed with this higher frequency alternator output or anything else that depends on grid frequency (like grid frequency based clocks - common on some kitchen appliances), but you can easily run anything with a switching mode power supply, like computers, laptops, phone chargers, TV's, monitors, etc. Thanks for watching!
Correction to your video. The voltage between phase to phase isn’t double. It’s the product of phase to neutral x 1.732 because the alternator is wired as wye so a three phase service is much different than a single phase service in terms of values.
Or root(3), if you like.
a list of everything you are using would be great and would this run your house say in my case 2-3 kwh ? im new to this idea and my power bill is getting out of control for no reason 300-400 monthly was looking for a alternitave with a car alt does the amp of the alt matter what all are you using in the video ect...
I feel like no one except rich people , businesses and grow opps have that problem . Which are you ?
Where did you get transformer from?
Got it from an overhead projector. Thanks for watching!
Hi ,
I have a Vauxhaul van 1.3 diseal, can I generate 4000W output by upping the alternator? I want to run a coffee machine which needs 3200W, and few other kits.
Yeah, you could install a 350 amp alternator, but if you need AC 230 or 120V for those appliances, you'll still need an inverter. I don't know the prices for those high amperage alternators, but they sure aren't cheap, even the stock ones usually aren't, not to mention the price of a 4kW inverter. The easiest and cheapest option would be a generator, but those things aren't that small at 4kW continuous power. You could use a few cheaper alternators, like 3x 120amp or something, but there's still the inverter issue. You can find some cheap ones on ebay, but it's still a couple hundred bucks and you can't know what you'll get. One more option would be to modify the coffee machine to run on 12 volts directly. Thanks for watching!
@@ElectronPower you are simply great. Thanks buddy.
I have a generator, but operationally its a bit mess.
How do i convert coffee machine run. On 12v?
@@tcstigers It depends very much on the type of coffee machine. If it's just one of those simple ones, you'd probably "only" have to make a 12v heater or something that'd fit in. But if there's a lot of other stuff in there, besides the heater, like in an espresso machine, it's probably not worth it. You can get simple 12v coffee makers on ebay if that's what you need, but they're probably far from 3200W, so the heating would be rather slow, compared to your machine.
Hi, just getting into this, but how much voltage would a completely unregulated, standard 4-pole alternator produce at a decent magnet strength and 3000 rpm? I'm curious how much a regulator actually scales these things back from, and how high a voltage you think they could achieve given free rein. Say a ten pole, at 3000 with a standard magnetic strength? Does voltage increase most with more poles, higher magnet strength, more wire? And does it scale linearly upward endlessly?
I'm currently writing a book where a character is creating an alternator in another world as a source of electrical generation separate from having to use magic, as I love realism, and am stuck on trying to figure out just how much a regulator scales things back. I just don't understand well enough the relationship between it all, and everything I read seems to assume a regulator will be in place.
In a world where you wouldn't have to fear the charge generated off a device like this, how would you go about making one as strong as possible?
Thanks for a reply, if I get one!
Hi! It won't even produce any voltage if there's no regulator. The regulator supplies the rotor with magnetizing current (more current to the rotor means you can get more current from the stator). And by changing the rotor current, you can also regulate the output voltage, since less rotor current means less stator current and if the load that's connected to the alternator doesn't get enough current, it'll automatically cause the voltage across the output leads to drop and regulator also "knows" when the voltage on the output is not correct and will try to correct it, by either increasing or decreasing the rotor's current. In this video I'm just applying the magnetizing current to the rotor manually, without regulator, but as far as I remember, the higher magnetizing current doesn't increase the voltage that much, but it will sure keep it higher when there's a heavy load connected to the alternator. The ratio between rotor and stator current if I remember correctly, is around 1:10, so 7 amps on the rotor, to get 70 out, on that 70amp alternator, assuming you have the right rpms and enough power to keep them from dropping. Thanks for watching!
@@ElectronPower Oh, ok. Then if you had a regular magnet in use instead of an electromagnet, it would produce at a constant rate and require a regulator to bottleneck it's output to match whatever appliance was using it, right?
Also, new question. When determining the output of an alternator in watts, the equation is volts multiplied by amps. So, what does that mean in watts? Is that a watt/second or a watt/hour? Is there a formula to convert a watt to a watt/second/hour? A 24v alternator producing 50 amps of energy, for example, is 1440 watts. Now, thats 1.44kws. I've seen conversion formulas that state a KW/H is W/1000(Hours of use) for consumption of power, but is there a specific formula to go from 1440 to watts produced per second? Per hour? I guess I just don't understand what 1440 watts is being measured against time wise when you determine the units output.
Well in the world of math and reality, sometimes have to go into the imaginary world to solve problems in the real world, the same goes for electrical magnetism, you need to look up on the internet and understand why and how a alternator works. an alternator you're not really getting something for nothing, because it takes energy to transform DC to AC , then back to DC. So it's not efficient, and energy is wasted as heat , Regulators don't scale things back, they function exactly the way they were designed to, to regulate voltage of the output based on a input voltage
So your setup requires energy from the wall to start, but makes electricity on its own?
Felipe Rodea Nope, this setup takes electricity from the wall socket to make even less electricity. Normally it would be taking energy from internal combustion engine, to make some electricity and some losses. What you're looking for is a "free energy device" / "perpetuum mobile" which does not exist.
What is the best way to generate 60 Volts DC from an alternator to charge 48 Volt battery bank quickly?
Correct voltage for charging a 48v lead acid battery should not exceed 4 x that for a 12v battery or 4 x 14.4v = 57.6v max! Otherwise you will be in severe danger of completely knackering your battery - using 60v for extended periods WILL do that! How quickly any battery will charge up (safely) will depend on its state of discharge, amongst other things. The more discharged, the longer it will take at nominal charge current (10-12 amps MAX!) unless you drive excess current into it at which point you are in danger of knackering it again. It will also depend on the type of battery (deep discharge leisure or spike load starting battery which should really not be allowed to fall much below 12v (for a 12v battery) and absolute minimum of 11.1v so multiply those figures by 4 for a 48 volt battery.
Alternator output in volts will depend on excitation current and revs. Since a typical car alternator is designed to match peak revs of the car engine at roughly 2:1 the maximum revs you should consider using would be somewhere in the region of 2 x car peak revs (typically 6000 rpm or less) so around 12k rpm. Other considerations are the peak inverse voltage capability of the rectifier pack - typically 50volts for the "cheapo" diodes typically used and mounted in a totally CRAP way in an alternator. Easily remedied though by purchasing a 3-phase rectifier pack from eBay capable of handling the current you expect (100A @1600 volt versions available for around £8-£20 ish) and remember that there MAY be issues of breakdown voltage between windings on both the stator and field coil as well as peak load output. Getting the voltage is probably the least of your worries, ensuring you don't overdrive the field coil and produce excessive output current and volts that easily exceed the original alternator's total power output and voltage/current capabilities will be a bigger problem. Remember that increasing the output voltage by ten times - from 12 to 120v or twenty times to 240v brings its own set of potential problems albeit that for the same output power your output windings will only have to handle 10% of the output current. The same will NOT be true of your field coil!
Regulating the output voltage is easy - just find the voltage at which the field coil provides the correct output voltage and regulate that field coil voltage. Use output voltage feedback to maintain the field coil volts/current and that will regulate the output voltage. Essentially that is all the normal regulator does. However that alone will NOT regulate or limit the output current, neither will it provide proper temperature monitoring and control (shutdown or power reduction) on output current overload. If you understand electronics and electronic design your options are wide open. If not, do yourself a favour and steer well clear - get someone you know who both understands the subject well and has done it before.
[edited as I missed this! The other way is to simply use the method in the video of course and use a transformed output to get the necessary secondary voltage you need.
Your output is being limited by your under powered, (Current capacity), transformers and possibly by the battery capacity or charge condition that you are energizing your field with. I am at a loss to understand how you are passing what should be DC power out of your diodes through standard induction transformers. Did you bypass or eliminate the diodes or were they just shorted out by defect or overload? Normally, passing full power to the field coil and regulating the speed of the rotor could yield 120 to 240 VDC which is usable for lights. appliances or tools using brush motors. In this configuration, frequency wouldn't be an issue at DC voltage.
Jeff McCrea My output is limited by the washing machine motor. These transformers together can handle 500W, so 100W light bulb wouldn't be a problem. The problem is that only about half of the input is converted to electricity due to low efficiency of the alternator. Thanks for watching!
Could she run multiple alternators in conduit? 🤠
@UC9YfcWkR-7QGvc4odzxR1Sw I'm not passing DC through the transformer, the power is tapped BEFORE the diodes. Thanks for watching!
It would be nice if you could show us how u built it with detailed information so that anyone who wants to try this can do it with confidence and not run the risk of electrocuting oneself. Explain where everything goes any why it goes there.
Hello! Are you using the same battery? And can this be used for domestic power in a farm house without electricity?
Same battery? -What did you mean by that? Yeah, if you run an alternator with an internal combustion engine or something like that, that doesn't need electricity to run in the first place, than yes, but you can't use this setup to power just any type of device, as the frequency is (as you can tell from the video) a bit higher than standard 50-60Hz. You won't have any problem with lights (except neons, hid's or anything like that, that uses magnetic ballast - these types of lights would probably still work, but not at rated power), computers, tvs, heaters, chargers and stuff like that, but you can't use this to power devices, that have induction motor, as an induction motor needs proper frequency to run properly. I'm not sure about universal motors, but I think they should run fine at higher frequency (universal motors are used in things like power tools, vacuum cleaners, food blenders, basically any type of device with that typical, loud sounding motor). Also, clocks, like the ones on microwave ovens, usually rely on frequency, to keep track of time and if that frequency is not accurate (50 or 60Hz), you can imagine what happens. You could run the alternator at lower rmp, to keep the frequency at 50 or 60Hz, but the efficiency at that low speed would be terrible, I imagine. If you like to build stuff and you want to try this, then go ahead, but if you just want something that works and don't want to waste your time, dealing with this stuff, I'd recommend you to buy a cheap generator (new or used one). Another option would be to use alternator, to charge batteries and then power your devices with a pure sine inverter (you can run anything on it, as long as it's powerful enough) - you can get them on ebay at quite low prices. If you have any more questions, please post them. Thanks for your comment and thanks for watching!
when your load testing, the amount of amps input to alternator isnt enough , use a 600 amp car battery, to get the amps higher, if you have the correct ratio in Transformers
Magnetizing current is high enough, it's just that the washing machine motor isn't powerful enough. Thanks for watching!
so what have you accomplished? what all can you run? how can I get a benefit from this?
I'm confused why outputting 200W completely stops the alternator? In a car, they'll do over 1000 watts easily. What am I missing?
Hi! The motor that drives the alternator is a washing machine motor, with around 150-250W of power, not sure how much exactly (it doesn't say on the motor). That + the efficiency of alternator (around 60% at optimal speed) and you get like, I don't know - maybe 100W of output if you're lucky. Car engine produces tens of kilowatts, at least, so that's not an issue there. Use like 2kW motor at the right speed and you'll probably get 1kW out of the alternator if it can handle 1kW. Or use small engine, like lawn mower engine or something, that's like 2.5kW or something like that. Thanks for watching!
@@ElectronPower you saved me time and money that's what I was thinking to do I owe you thanks
@@Biggtimeman No problem, man! Thanks for watching!
Looks like solar is the only best was for my bug out camp
@@Biggtimeman Yeah, if you don't need lots of power, it's certainly affordable enough, but the price quickly adds up if you need kilowatts of power.
One of the best ever on youtube
Thanks! And thanks for watching!
That is a cute setup for theory's sake but if 260 Hz is useless in the real world, why not just energize the field with direct DC from
your battery and take your output from the diodes? You can generate 120 VDC and run lights all day. I acquired a shit ton of lithium ion
batteries a while back. For laughs, I wired up a 120 VDC, give or take, battery pack. Just to see what would happen, I wired it to a CFL
bulb and it completely bypassed it's internal circuity and lit the bulb. I screwed the bulb back into it's fixture and it worked fine. I couldn't
say if leaving it connected to DC for longer would damage it's circuit or not. It was just an experiment.
Great demonstration,
Can you run the washing machine motor off the output effectively creation free energy?
Weedy and The Doc Won't work. This idea occurs to every school kid at some point. The problem is that both the generator and motor driving it are less than 100% efficient. Energy is lost immediately in both units as soon as you remove the power required to start them and the combination quickly runs down--no free energy. Expend your efforts on something else. You'll get much more satisfaction.
You don't and CAN'T get more energy out than you put in...
If you can apply flywheel power this will work, if it can produce 240v at 180amps, i guess thats free energy enough for me
Hi waht is that silver cylinder? And how does the resistor works?
It's a capacitor. The resistor limits the current that goes to the rotor and decreases the strength of magnetic field that the rotor produces. It does that by taking some of the supply voltage, so less of it goes across the windings. Thanks for watching!
@@ElectronPower does a voltage regulator would do all that? Or still need a cacitor? Thanks for your answer
@@douglaszylberkan8182 Capacitor is there to shift that single phase and (kind of) create a second phase, which is 90 degrees off the first one (normally they are shifted by 120 degrees in a three phase system) but 90 degrees is enough that when applied to auxiliary winding it adds a lot of starting and running torque. (it's a run capacitor). You also have start capacitors which are much higher capacitance and work similarly to the start capacitors but due to their higher capacitance, send much higher current to the start winding (it could also be auxiliary winding I think), so they provide even more starting torque, but are disconnected when motor reaches certain speed, by a centrifugal clutch switch or a relay. The rotor winding can also be controlled by a regulator, yes, that's how it's normally done, but the regulator was dead on this alternator.
hi....just to add some info.: i rewound many microwave transformer secondaries, with either #8 or #6 wire: number of turns needed for whatever project i was doing......
also...what is the 'ohmage' (my word) of that big resistor.....end to end no taps....
what about one transformer for each phase.....??? using common centre
@@petersack5074 I think it was 100 ohms, but 10 ohms would be better for this purpose, or 20, maybe. Why one transformer for each phase, do you need three phases?
i have an alternator like that, the rectifier and voltage controller is bad, i have removed it, i have been trying to power the rotor with 12v battery, but it was not moving, please i need your assistant to get it move
Nice video and nice and clear help thanks for making this video.
Now if you also added a ground wire coming from a brush on that alternator you'd then not have any drag and still produce the electricity you desired even with a load
Yeah, seems like a good idea at first, since that's how it's originally done, but no matter where the energizing current comes from, it will still increase the driving torque on the alternator, thus loading the washing machine motor. If anything it would be worse, since now you have to provide torque for the magnetizing current too. Thanks for watching!
which kind of motor you use? Single phase or three phase.
The Anjneya Vasu Channel Hi! It says it the video, it's washing machine induction motor (single phase).
how much current can the alternator produce? does the alternator max current drops proportionally as you increase the alternator voltage?
Tibor Kiss Output is around 70 or 75A for this model (I don't remember the exact number). Current only drops if you put load on it. If the magnetizing current is increased, the voltage also increases and thus the current also increases (assuming there's a resistive load connected to the output). Of course you can only increase the magnetizing current up to some point and after that you can overheat the windings. And the optimal RPM range for most of these alternators is 5000-6000rpm, so that washing machine motor is a bit on a low side (I think it runs at around 2800rpm) but you can always increase or decrease the pulley size on the motor to get the right RPMs. Of course the power of the motor stays the same if you do that but the alternator runs at a speed that it's more efficient at. Thanks for your question and thanks for watching!
Electron Power great info, thank you! I am trying to build a 200v dc generator, capable for 100amp output. I plan to use a small diesel motor and two watercooled car alternators with their diodes removed and rectifiers changed. Thanx again for sharing your knowledge.
Tibor Kiss No problem, good luck! ;)
Thanks for u video sir,,, now i have some questtion,,
1. the alternator running 800-1200 rpm,,
2. i connect another batery to power rotor,,
3. now i get 11vdc-14vdc from the alternator..
now its the problem
1. output alternator is DC,, if i conncet it to the tranformer 12vDC to get 220vAC... Is it possible ???
2. or i must convert DC output alternator to AC for input use to tranformator ??
sorry sir,,, my english so bad,,, i just leaning without techer...
Achiles Stavros No, you cant use DC on transformers. You need to connect transformer directly to alternator's windings (not to the output of regulator or diodes). Thanks for watching :)
Electron Power thanks sir,, thanks for your help,,, some problem here sir...
but the alternator winding output is 3 phase sir !!! how i cann connect 3 phase winding output alternator to the transformers, ?? or i must modification 3 phase output alternator to the 2 only output for the transformers. !!!!
Achiles Stavros That's true. No, you don't need to modify anything. There are four output leads - one of them (common) connects all three windings together and the other three are separated endings of the same windings. Do you have a multimeter? If you do, try measuring resistance between all of those leads. You should get two different values. The lower one is between common lead and one of the other three leads (this is where you'll get lower voltage output). The higher one is between any two of the three separated leads (L1, L2 or L3). This will give you higher voltage (lower voltage × √3). When you connect your transformer there will be two unused leads (you only need two for one transformer).
thanks you very much sir,, thnaks you for ALL... now i understand how the alternator work and more... thanks sir
Achiles Stavros No problem, you're welcome :)
QUESTION!!! so if i was to input 36v i would get 360v out the back end?
Alejandro Aguilar If your transformer is in 1:10 ratio and can operate at such voltages, then yes but transformers only work with AC, so you can't just use batteries, for example. Let's say you have 36V to 360V transformer - when you connect it to 36V AC supply, you get 360V AC out. If you try that with 24V to 240V transformer, you'd probably still be able to get 360V out but there will be a lot more wasted power and excessive current on primary - this can cause the transformer to overheat and fail. If you're gonna try it with 24-240V transformer, keep measuring the current while raising voltage to make sure that the current is not too high. And one more thing: the insulation on the transformer will most likely withstand 360V although the transformer is not rated for that voltage but be aware that you're doing this at your own risk and if you fry your transformer or get hurt while playing with high voltage, I'm not to be held responsible for your actions. I'm not trying to scare you - the insulation would hold up almost certainly but you have to be prepared if something goes wrong. And use your brain - don't touch the 360V output (or anything above 50V without current limiting - plasma ball has a high voltage output but the current is slim to none, so it's safe. wall socket has a much lower voltage but the current is vitrually unlimited relative to human body's resistance and so it can be deadly). Thanks for watching!
Thanks a bunch! So here is what i am trying to achieve 315vac / 300amp With a single Alternator or more than 1 , i had thought i can get the 300amp with 3 - 100 amp alternators. What are your thoughts PROFESSOR ?
Excellent vid, demo, knowledge, thanks for sharing, please do more, ur great mate!
Evan Wittwer Thanks for your positive comment and thanks for watching! I will definitely make more videos like this one ;)
How much VA have the two transformers ? Thumbs up :)
Alex
Hi, Alex! They have 250VA, each, but this was overkill for that setup. I don't know the ratings of the motor, but if it's 200W, with 85% efficiency and if the alternator has 60% efficiency, assuming no losses in belt transmission, this setup could put out 100W maximum. In reality it puts out only 50W, probably due to rpm drop (because of too weak motor). Alternator becomes very inefficient, when rpm drops too much. This setup would probably work best with 3.5hp lawn mower motor or something like that ;) BTW, alternator I think it's 840W. Thanks for watching ;)
Electron Power Ok :) 👍👍
Seems like a really noisy way, to light a lightbulb. Also you say 120/240 volts. But never mention amps. There are pretty bright 12 V lightbulbs out there that would work just as good without all the noise. 🤷♀️
I never mentioned the current output because it's highly setup dependent. The point of generators is not in being quiet, it's in conversion of mechanical to electrical power, but if you don't like the noise, you can still connect your alternator to a wind or water turbine, or even to a bicycle.
You'd still need to run your 12V bulb... Lower voltage doesn't mean noiseless. But if you meant hooking up the bulb to a battery, then you obviously have no need for a generator, so why even bother watching a video about generators? And BTW, you can also run other things with this setup, not just light bulbs; such as: all sorts of chargers (laptop, tablet, phone chargers, wall adapters for various electronic devices, computers, monitors, TV's, devices with universal motors, such as food blenders, power drills, angle grinders and other similar tools, but you can't run a drill press or other machines with induction motors). This is a 70 amp alternator, but when the voltage is stepped up to 230V, you're left with about 4 amps or 8 amps for 115V. So the power is close to 1000 watts, but you have to be able to deliver about 150-200% of that power to the alternator, which means that you need at least 1.5kW internal combustion motor or other source of mechanical power to drive such alternator at full power, but it depends on RPM's and efficiency of your alternator and drive system. Thanks for watching!
i need something that can handle a total of say 3000-5000 watts at 120 v A/C 60hz or so is this posibble with this car alt idea???
juggalo4life_91 Alternators are usually rated at around 1kW, but it is possible to get more powerful alternators, although they're expensive. Another option is to use higher number of alternators... However, the frequency will not be 60Hz at full power, but much higher. I'd say that your best and cheapest option would be a gas/diesel generator. Thanks for watching!
Electron Power I have 2 extra Mechman Elite series 320a alts from my car audio build if you don't know why I would need 6 ( only needed 4 ) then check out my close friends UA-cam channel EXOcontralto and a guy at a car audio competition told me about the alt(s) can be turned into a home power generator some how idk what type of how big or small how to bring up the volts what's it takes to get 120v at 30hz and enough watts to run 3k-5+k per hour is not exactly like car audio I don't want to use a gas motor for power I have a electric motor from a dryer thought I could put it in the loop somehow but the rest isn't like oh ( alt to bat to amp to sub ) this type of stuff to power a home is tricky you got to step up this bring the hz level the amps and watts idk what kind of battery to use lol I need a list and equation numbers or a picture of what I need lol sorry for rambling on
juggalo4life_91 Yes, I know exocontralto's channel, he's a great guy. If you want 5kW out, you'd probably need at least 10kW motor to turn the alternators. One way to get 60 hertz out is to use inverter, instead of direct alternator output, but inverters are also pretty expensive at such high power ratings. May I ask what's the point of using such setup if the motor will be electric? Why not just use the power source you'd use to run the motor with?
Electron Power cause the only thing I have on hand is a electric motor from a dryer I don't have a gas motor to use and I have 2 old liquid car batteries rated at 1200CCA 12v...... Would say a gear ratio setup work like a mountain bike uses to increase speed with less power input on the electric motor or is that overkill idea? I'm just trying to make things work with what I have on hand if you will...
juggalo4life_91 Oh, so you want to get 120V out of batteries? Then it's best idea to use inverter ;)
PS: dryer motor doesn't have anywhere near enough power to run those alternators at full power + this setup with motor and alternators is pretty inefficient. It's really best idea to just buy inverter and it will also be much more efficient (less drain on batteries and longer working time) - not to mention a lot smaller, lighter and overall more practical + quiet
This car altr is it a 12v or 24v , thanks 4 help
12V
What's the amperage tho ?
Depends on your setup... If the engine has enough power to drive the alternator at full power, you'd get the full output of the alternator (in case of that alternator; 70 amps) which means about 7 amps at 120V or 3.5 amps at 230V, theoretically (transformers are nearly 100% efficient). Thanks for watching!
@@ElectronPower thanks, great video by the way.
I'm not sure I get the point. Aren't you powering the the washing machine motor with 120V AC, then using that to power the alternator and then using that to produce 120V AC again. If so, what is the point. Maybe you are doing something else I don't understand?
Hi! Actually I'm using 230V, but yes, that's basically what I'm doing. And the reason? It says in the title of the video. And in the beginning of the video, it also says you'd normally use internal combustion engine or something else to spin the alternator. This was for the demonstration purposes only. Of course it's pointless if you already have 115/230V available from wall outlet. Thanks for watching!
@@ElectronPower I disagree that it's useless if you have power already available.
@@matthewmeuleman3369 And why would that be?
@@ElectronPower there are three types of UPS systems manufactured, static/ batteries, Diesel generators and rotary/mechanical. These are used in many mission critical applications as well as in hyperscale data centres.
Transformer also provides electrical isolation, so would be safer for people on the secondary side, requiring to make contact between active and neutral, not active and earth.
@@matthewmeuleman3369 Well, but this is not UPS - if power goes out, this system also dies. What do you mean by rotary/mechanical? And why wouldn't diesel generator fit into this category? You can still have isolation transformer without all that mechanical waste of energy. Why would it be safer? Contact between "active" and neutral? Like connecting themselves across live and neutral? If anything they'd be safe making contact with ground, while holding the live and that's the exact purpose of isolation transformers - to get rid of that relation to ground.
How do I convert the output frequency of 260Hz to 50Hz?
kazeem mustapha You would need to use the DC output of the alternator and feed it into an inverter, an electronic device that changes the DC electricity into AC power. You need to look for one with the appropriate voltage and frequency.
Great demo.
RODALCO2007 Thanks! And thanks for watching!
Im interested in this
What does this help with ?
@@fidelcashthrowed7272 Power a 120v/240v grinder off your car's alternator next time someone clamps your wheel.
I cannot believe that 17 years working in a junkyard I never put one and two together or was that too and to LOL I am going to assemble the biggest generator ever made and it's going to be so propelled on its own juice
you are saying that simply putting 6V -12V to the alternator will turn the alternator to a motor and then you can tap directly off the windings to get AC?
Don't you have to modify the alternator to become a motor?
Will you put one together for me and. Send me the bill I'm living in a shuttle bus and new cool air I'm in Florida now
Sorry, but I only build things like these for demonstration purposes. And not even that anymore, since I'm just too busy right now. I'm hoping to at least get back to my hobbies at some point in the future and youtube, perhaps. Besides that, the shipping for a heavy thing like that, from EU, to US, would be enormous. If you need 120 or 240V supply, your cheapest option is a generator. Here, I'm using electric motor that already uses mains supply to drive the alternator. In your case you'd need something that can run the alternator off grid if you wanted to go this way (a wind turbine/water wheel, etc.). This project is more for the people who like to build stuff themselves from things they've got, so a generator is by far a better option. It's cheap, offers a lot of power and it's optimized just for what it does. For small stuff, you could buy a solar panel and a battery. Add to that an inverter and you can charge your cell phones, power led lights, etc. I am glad you like it, though! And thanks for watching!
PS: if you need cool air, I'm also sorry to tell you that things like AC and fridge compressors pull enormous amounts of current on startup, and it's questionable if 1kW alternator like that, could start an AC. As mentioned in the video, there's also problems like alternator's frequency (260Hz), which is way too high. You need 60Hz for your AC. So, maybe a generator, together with a small AC unit would be the way to go.
after the altenator always go to a storage go up after that.
excellent video
Listen, this is a very common human behavior. He gives just enough information to make you interested but not so much that you could run out and replicate what he has done. He only wants certain people to be in the club. Who can be in the club? People with previous training / experience in the electrical field. Otherwise you will be told "it's all in the video." Which it is....but it also assumes the viewer has a given level of previous experience. The video producer loves the felling of having knowledge that others desire and is teasing others while demonstrating his application of previous acquired knowledge to accomplish a goal that is outside of what pedestrian consumers would do. It's a massive ego stroke.
Kevin Johnson sounds like your jealous ,
It is not a complicated set up and it's easy to see how to wire it and what you need.
It's a shame that you don't posses the knowledge or skills to replicate this. Maybe you should do some training and research if youv got the nous to do .
Ya either got it or you don't.
Not jealous. I do however appreciate the knowledge and skill. As far as possessing the knowledge or skill, what makes you think I don't? Perhaps instead of answering people questions with "it's all in the video" with a more in-depth explanation? If someone is asking then one must conclude that the video narrator has left out some details or has assumed a given level of knowledge. If someone is asking you a question, I would hope that you would take it as a compliment as the person has interpreted you as an authority or expert on the subject. To state "it's all in the video" is dismissive and you are missing out on an opportunity to do what we are here to do on this planet....help one another.
Kevin Johnson what is it you need to know about it?
Evan Cundall What is one to do in a world where it's f*ck or get f*cked but you'd rather live and let live?
Kevin Johnson what are you trying to say man?
How much current is being lost by using that, "power resistor"?
You do realise that modern electronics are frequency dependant, so that leaves only the light bulbs, unless they are energy saving bulbs.
SO, ..... what exactly is all this high frequency voltage good for ?????
Not much, but I didn't measure it. Besides, you can make a simple, adjustable current source, that's much more efficient if you're worried about that. This can run almost anything, except the things that use induction motor. It can run computers, cell phone chargers, TVs, heaters, light bulbs, but of course you have to have enough power available; powerful motor and alternator. It'll also run anything with universal motor, such as most corded drills, vacuum cleaners, food mixers, circular saws, miter saws (saws like table saw won't work because they use induction motor; drill presses also won't work as they usually also use induction motor which is frequency dependent - speed of it varies by varying frequency). Thanks for watching!
what do I need to get 120v out of an alternator
12v to 120v transformer. thanks for watching!
The stream of water
Into the pond must not become less than the stream leaving the pond.
I guess you're referring to the 200 W bulb as a gaping hole in the dam.
Or a 617 squadron bouncing bomb.
Im putting this theory to test, to get around the regulator, my thought was to apply the DC output of the alternator that would normally be used to maintain Bat voltage while vehicle is in operation, to energize DC to AC inverter, giving me a AC output at 60 Hz to energize a AC motor and to enable a AC relay and driving a second Alternator dropping Battery out of circuit and maintaining the DC motor driving the first alternator. This would complete a closed loop circuit self sustaining Just as in a Auto the Battery is used only to start the engine, then is maintained by the Alternator. By adding additional Alternators and regulating the Frequency a 140 Amp alternator would provide more than enough power to operate the basic needs of a Home.
I'm not sure if I understand this correctly, are you trying to say you want to make a free energy device?
Very informative I’ve been trying to to this for awhile would love to have your input. Is there a way we can communicate other then this email Facebook text?
very good job
you need 2hp electric motor to be strong enough to turn the alternator. ..
Samuel Mateus It depends on the load on the alternator but yeah, that'd probably be enough for this alternator at full load. Thanks for watching!
Good jobs
can I get the. wire schematic please.
Oscar Portillo Hi, it's all explained in the video. Thanks for watching!
@cgwworldministries This circuit is so simple it isn't even worth drawing a schematic for it. It may look complicated but it's really not - if you have some basic knowledge about how to wire a transformer/motor, you'll easily figure it all out. If you don't have that basic knowledge, it's better not to even attempt doing this, as it could be dangerous for you or destructive to your equipment. Thanks for watching!
good work
use a shopvac 2 12 volt batterys and a inverter forever power no solor or turbine figure out how to hook it up easy
and x2 car alt
rick carp But that means you'll need to recharge the batteries every time. It's more convinient to just use gas or diesel powered engine and it also lasts much longer on a single tank of fuel.
put a refrigerator on it for load
Robert Martin Would need a stronger motor to be able to do that. But it'd be possible with powerful enough internal combustion engine. Thanks for watching!
Good job!
1:09 meter reading yet NOT connected on Red Probe,.!!
Chris Green Yeah, that's quite a normal thing with AC power - if I'm not mistaken, it's due to capacitive coupling. Thanks for watching!
good work !!!!
Thank you! And thanks for watching ;)
To smart for me. I'll just stick with medicine
It's not that complicated, just an alternator and a step-up transformer. Wikipedia might help. Thanks for watching!
brilliant
Thanks for watching! :)
Yep too smart for me. I will just stick with quantum physics and astro intuactality
I see what you did there 😂😂😂😂
Thought I would bring some happiness to you all. Glad you liked it.
Fine as a demo, but in reality the size of the transformers have no practical use except maybe to power a simple low current light. You can't start a motor with it, and with a unstable frequency, its most likely a chopped sine wave, which most electronics won't function properly on. There are literally thousands of video's on the internet like this, until somebody comes up with a system that's safe and has a practical use, your just setting up some armature to get seriously hurt!
500W is only enough for a low current light, you say? Not to mention you could easily use larger transformers... I wouldn't even try to start a motor with it, as they are frequency dependent (at least induction ones), but you could run anything with universal motors, such as corded drills, mixers, vacuum cleaners, practically any handheld power tool, as long as you use the right sized alternator, transformer and drive engine. There's no reason for the output to be "chopped sine wave" and actually, most electronics will do just fine on chopped sine wave, square wave or even DC. As the video says; hook an engine to it and it's "practical". If it's not, modify the design, to make it practical for you... I'm pretty sure I won't get hurt with a set up like this, buddy. And even if I did, so what? -I'd get hurt doing what like. How exactly do you think technology progressed as far as it did? -There were people like me, experimenting - and yes, some did get hurt, but that's what can happen when you do something. Avoiding danger and unknown hasn't helped us make technological progress. Thanks for watching!
All storage should be caps.
I don't see the point. Takes a lot of juice to turn that 2 HP motor and even more with a load.
To turn what motor? If you don't see the point then here is a citation from Wikipedia on electric generator: "In electricity generation, a generator[1] is a device that converts motive power into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines and even hand cranks." - so it creates electricity where you need it but you only have "motive power" available. In this video I've used electric motor as a "motive power" source, just because I don't have any internal combustion engines I could've used an because it isn't really good idea to run internal combustion engines in closed/nonventilated spaces. And if you're still thinking about how unefficient this setup is - as I've said, it's not optimized and even if it would be, it would still be inefficient, because generators (at least most of them) are quite unefficient machines.
One similar example of question to yours would be: "why don't you just plug the bulb into the wall outlet?" - and you'd be right but that's not the point of this video.
Thanks for watching!
Electron Power like I asked before. What's the point or purpose?
Dave Rogers Are you kidding me? Read my answer or try harder to make a better question if you want to know something specific. I'm sorry but I can't spend my time answering your question only to get the same question again, without any explanation on why you're not happy with the the first answer... As I've said - in place of electric motor there's usually an internal combustion engine - you fill up the gas tank, start the engine and you've got electricity in the middle of the desert, far away from any power plants - without this device or any similar device, you'd be unable to use electric devices in such location.
Electron Power what you have there will not run anything for very long and the idea that your going to have those components in the middle of the desert as a power source is ridiculous so what's the point or purpose? What are you trying to do? There's easier more reliable sources of power. Especially in the middle of the dessert where sunshine is abundant.
Car alternator doesnt go that fast
Really? This was about 3000rpm (a little bit less) and they usually reach their peak efficiency at 5 or 6000 rpm. Thanks for watching!
I put a hundred amp load on that thing and prove something
Did you record it? So, what have you proved, exactly? Thanks for watching!
Sorry that was a typo I would like to see a hundred amp load put on it see how it holds up I'm presently working with a hydrogen based generating system would like to see one of these alternator types actually produce a little more into 60 amps
@@homermcclain7694 Well, I would like to try that but I'll need a stronger motor/engine, to do that. I have a lawn mower engine with a broken connecting rod and a hole in the crankcase - I could repair it and power the alternator with it, but the trouble is; I can't remember where I put the piston, so I can't do that right now, unless I buy a replacement piston, but I don't think it's worth the money, so maybe one day I'll be able to try this, but I can't promise anything. Anyway, so, you want to generate hydrogen with a setup like this? -Then why not just use a battery or buy a high current power supply? -They are wery cheap on ebay.
Just speak, so I don't have to read
Ok I'm wanting to run an alternator and an inverter to get clean sine for a tv... I'm sitting here wasting my time because this was obviously for 240 European cramp... so if this wasn't another one of those 'silent' movies where the person filming it wasn't too scared to freaking talk, his accent would have given away the fact that this was an EU minded video.... what a waste of time for me.
The video says it all buddy. If you're too stupid to swap the 240V transformer with a 120V one, then I can't help you, because you clearly don't understand a simple explanation. EU minded video? Doesn't the title say 120 OR 240V? Yes, of course I'll be using a 240V transformer, since 120V ones are kinda hard to find here, and this was just for demonstration purposes, the principle stays the same with 120V transformer. "European cramp"? Are you one of those "think I'm privileged/worth more than others" Americans (in other words, Trump supporter?) You find a video on youtube, sharing free technical knowledge and yet complain it was made for EU scum, rather than for you, privileged American (not to mention that the video clearly explains the things you need to know about voltage). You don't need sine wave for TV, modified sine wave is perfectly fine. Use an alternator that still has a working regulator and hook up the inverter. And at least add a small lead acid battery to the output of the alternator, to stabilize the voltage. Thanks for watching!
That video is b/s
Great video!
Thanks! And thanks for watching!
why not just get a lamp
