Oh cool, it brings back memories of when I was around 10 years old. I didn't have much money, so I went to a car graveyard to purchase one from a nice guy who owned the place. I paid $5.00 in 1973, but it came with all the basic electronics. My dad gave me an old car battery. My mom was not aware of my project, but my dad did lol. I assembled the turbine with random pieces of aluminum sheets some workshop leftovers I got for free. Anyway, I was able to install it near our tree house as there was a wind corridor because of the path leading to the family cottage. It worked and we were able to power lights and a car radio. No inverter though, just 12 volts of DC power. The battery charged as the turbine turned. It worked for a couple of years until a storm with 100 Km/h wind destroyed it. Anyway, thanks for sharing your video showing your cool project.

yes, the thing is car alternator needs high rpm and high turque to generate power, and if he connected any real load to it the wind turbine would have stalled, if u want wind power u need a realy big turbine with 2m long blades and and a gear or pully to increase speed on the generator, or use low rpm generators.

I agree definitely 10/10 on engineering skills. Maybe this footnote will assist others and yourself while you look for a way to change the drive ratios. I haven't built my own turbine yet because I'm still working on other projects that are required to come first. Anyway refrigerators in general use 300 to 800 watts of electricity and between 3 and 6 amps at about 120 volts. A 1hp well pump uses 750 watts. If it operates on 220 volts Alternators need to spin about 2,400 rpm at idle, their maximum output is above 6,000 rpm but not to exceed 8000rpm. Best wishes and good luck!

This is good for a first try. I'm interested to know what brand and model that alternator is - looks like a pretty beefy car alternator with a good-sized stator for a small wind turbine. Most car alternators are too small for a wind turbine of this size.

That is how most small wind turbines are built these days. Forget the many suggestions to add ratio gearing - no successful small turbine uses gears, belt-drive, or chain-drive. That is just what people with no experience always try, but leanr the hard way it just introduces moe failure points.

You could use the current turbine blades and gear up the alternator speed by having a simple two wheel pulley system. You could do a 15cm wheel on a 5 cm wheel with a belt connecting them with a 2cm gap and that would do about 700 rpm without taking up too much extra space.
Play with the gear ratio, and I would recommend using a small solar panel to charge a super capacitor to excite the rotor coils (field winding) then once the alternator is producing voltage it could charge the super capacitor to keep the field winding energized.
A large gear (say 60 teeth) takes longer to do a full rotation than smaller gear (say 12 teeth) will. I have seen this work and will increase the rpm, unfortunately the way that this turbine is set up it would require a rework as the blades would me the large gear and there is no option to gear it like a mountain bike in configuration. If you can find an old series from the Discovery Channel called “The Colony” they do it in season one.
@daveapplemotors that is the reason behind the super capacitors, but the solar panels are primarily intended to provide energy to the system for the excitation current during the initial period from a dead stop to operating speed. Once the system is generating power it will keep the capacitors charged. Now assuming that the capacitors become depleted after sunset, you can either have an auxiliary battery or a connection to the primary storage batteries through all relevant circuitry.
@@Poorboychickencoop🤦🏻♂️. Man see the accent is indian so here in india we don’t get 24V alternator in any car and chevy blazer never came to india 🤷🏻♂️. Make sense before commenting
Nice to see utilising the basic idea of wind generation but for deep knowledge you should study further for optimum production with less power/ RPM of wind power.
Hi. The windmill was almost certainly too small to turn alternator fast enough. A car alternator needs several horsepower to deliver the watts. Alternators give about 350 watts, and assuming 30% efficiency that means a one-two h.p. propeller at least. Very skilled video performance, well done. Cheers, P.R.
You must be 127yrs old, you can remember the output of the first alternator installed on a production model vehicle and the phase out of generators in auto use. Tell me, was that soon after -ve earthing became the standard and 6V was phased out haha. Meant in jest, but seriously your figures are way off. Electrical load demand on modern vehicles now with bluetooth this, sync that, infotainment, screens, high power audio, heated everything from glass, arse, to mirrors, 2 billion times the computational capabilities of the Apollo moon lander and more ECU's than the space shuttle means alternators in standard 12V vehicle regularly approach and exceed 100A rated capability. I'm sure you probably don't need a maths lesson so I no need to throw power figures around except to say that's significantly more than 350W. That alternator was commercial 24V (not my area, light motor vehicle for me) so current rating would be inversely proportional for the same power, handy for that type of project working with less current . The vehicles generally have high electrical demand also (did you see the size of that sucker?) starting a high cc diesel and feeding a couple of 25kg+ 200Ah or so batteries, so I reckon if they shared the spec that thing is easy good for 75A, at a charging voltage of say 27V, so 350W?? Oh, and by the way, I think you underestimate the power of wind and fluid/aero dynamics. Yes is was rudimentary, but the spinny thing was plenty huge enough to drive it (with some gearing). Nearly 30yrs ago a friend used an old steel bladed radiator fan (adjusted pitch I assume) no bigger than 18" with a scrapyard alternator driven by belt mounted on the roof of his garage (come man cave), and a standard 12V starting battery as storage/smoothing/capacitance to run a CB radio and car stereo (maybe some lights, I cant remember) and in a mild wind it would power everything without draining the battery ;)
@@bobbobovich4356 Hi Bob. Well done, I'm 128 next birthday. It's all candles and a ruined cake for me. Too much irrelevant stuff in your post, mate. F.Y.I. the power available from any windmill is proportional to the CUBE of the airspeed passing through it. It's the VOLUME of air that does the work, volume being a cubic measurement. The one in the video would run the alternator nicely in a category five hurricane (about 256 kph), but quickly self destruct. At normal wind speeds it wouldn't rip the skin off a rice pudding, there's not enough kinetic energy in the small volume of air passing through it per second. Gearing it up won't help. Try pedaling a bike up a steep hill in high gear if you don't believe me. Before eager beavers spend their hard earned money on a dodgy project, they should understand the cube law importance in windspeed, because it limits the maximum energy available. Commercial wind generators only work because they have huge volumes of air passing through. Now excuse me, I'm off to finish a homework project. Cheers, P.R.
@@daveapplemotors Hi Dave. Good point. Wattage varies with requirements of the vehicle. My "ballpark" figure of 350 watts probably applies more to a bus or long-haul truck generator running extra lights and air conditioning. My point that you can't get any more power out of an electric generator than its power input (vee belt, windmill) puts in is correct however. Inserting gearing between the drive and the generator will not increase the amount of power that can be extracted. If it was possible, perpetual motion machines would be exist. Cheers, P.R.
If I'm not mistaken the hoverboard motors u used in previous vids have n52 mags in.. try removing them. Or. Being a diy channel old hard drives.. they each got 1 in. . And they should be wide enough for that stator
i ues a leg of leg of one of the phase of the sate in rectifier & Now dc in to a copastor & back to the the burses & from the negative brush to the body of the alternator as the wind pick's up the alternator grows in speed & Bild charge in the run copastor delivers a steady voltage to the rotter as the sped increase's the prudish charging amps, An option is is to clang the copastor for vibrating pint regulated this works well & that will provide a regulate dc current to the rooter only . if we are to charge at a dist. To a bank of batteries , we should modify the stator in to a 3 phase to a Y stat that can travel the distance to the battery bank & the rectify at battery bank .
What you need is some sort of device to stop it from swinging in the wind when you go up on the roof to do maintenance. One gust of wind in the wrong direction and someone loses their face.
On rotor, by grinding /make space for magnets we can do.. . But question can we put magnet (in two parts) from magnetron of microwave.. Do u reply for experience
Only thing I would do differently is just use strong magnets to create the magnetic field so you’re not relying on an external battery source. Other than that I think you did an awesome job.
Habéis hecho un gran video y un gran trabajo que selo habéis curado, creo que lo único que os ha faltado es montarle en el rotor de 4 a 5 imanes de deodimio , en una posición de norte sur norte sur y hubiera aumentado el voltaje y el amperaje, enhorabuena por el trabajo realizado, un abrazo
Great video for educational purposes but is there a part two to see if you nail down the blade design and got enough RPMs to charge batteries. Saw some solar panels so wondering if this works in conjunction with solar panels as well
👍👍 First time I am seeing a video, which truly says that the expected voltage is not achieved so more (research & trials) are needed. Truly appreciate it. Dr NPSingh ONGC Dehradun
Would a stepper motor used as a generator give more power? I would think whatever you use it will be necessary to gear up the windmill rpm. Very good video.
This installation is very dangerous due to thunder strike, no surge arrestor or ground facility not installed at your working sight , its can cause damage your property or personal injory-
Guys maybe you could show exactly what you're doing, when dealing with electric stuff, point at it and explain what needs to be done ..just pointing a camera in a general direction and give general description is ...frustrating. Unless that's the purpose...? Otherwise, great project..
It would be easier, and even economical, to take advantage of the brushless motor of an electric scooter wheel, of which they are an integral part of the wheel, it would generate three-phase voltage, so you put a regulator-rectifier of the kind used by motorcycles with large displacement, and you would have regulated DC voltage ready to charge a 12 volt battery
Awesome project! I am finally learning about permanent magnet brushless ac and dc motors. Even though I have raced rc cars, built and fly drones for years i just started learning about this and I love it!
Why didn't you consider the windspeed in your area and calculate the windmill rpm ? and then check peak rpm for alternator to generate max voltage and then derive the gear setup to increase the rpm to the alternator. With a gear box, it's impossible to use a car alternator. 10/10 points for effort. 1/10 point for engineering
Hello I have solved your problem if generating. The rpm you need for any project that you are doing. I had put out a video a few weeks ago and was not going to share my secret until some tim . In a few days I will tell all my secret in how to generate 100 times more efficient from your alternator windmill and much much more stay tuned and please give me a thumbs up and I like as I will share with you and all on UA-cam My secret
I tried this once and was able to get a decent amount of power from a similiar setup. Gear ratio is definitely a game changer. I winder if there is a way to have variable gear ratio depending on the wind speed… i dont have an answer for this yet 🙂
A cvt transmission is the best option, the simple version that uses no control circuitry, is commonly found in snowmobiles while there are automotive versions. But with the right application of a snowmobile clutch/ cvt pulley is the easiest option that i can think of.
13:40 the blade seems to move on the opposite direction of the angle of attack. And also I don't see that much wind gushing since the nearby objects are pretty much stationary. Don't get me wrong, it's a doubt. Will be happy if you cleared it out. Btw love your workshop, wanna build one myself. 👍🏻
why not source some other ready made suitable alternator/generator. i have heard that stepper motors also make good generator. Actually this technology is need of the day as halala modi is making pre-meters and that type of rubbish controls. these is a viable business opportunity of made cheap.
Great Video! You are right to worry about RPM, a car alternator needs to turn at 3500-5000 RPM to achieve its full field amperage. If you are not looking for peak amperage but instead voltage, use an overdrive mechanism through a planetary gear box and ensure you are using a WYE type stator in the alternator. I daydream about making a wind powered alternator generator and appreciate that you did the work to see it through to the end.
Indeed, your thoughts are worth reading. I hope you will soon get your hands dirty building one. We love to get such comments and that's why we together with you all bring this channel to the best possible projects that we can
Hi guys it is of very good job but I do not know what is the wind turbine, if you have any good of generating more power you can become a new company to sell your product on a lower price so that every Indian can purchase.
@@wombatg0 Really???? I would love to see you try to back up your comment. Just for comparison, the alternator pulley ratio on a Cummins Diesel is 3.22 which equates to an alternator RPM of 8,050 with an engine RPM of 3,000. Typically, The standard automotive gasoline engine alternators have their full output rated at 6000 RPM but can continue to spin up to 12,000 RPM or more without any additional increase in output.

*What for?!? All practical tests show that small wind turbines hardly generate any electricity,* because hardly any wind blows close to the ground. *With solar panels, you can generate at least 20 to 30 times more green electricity with the same investment!* Moreover, the wind is extremely gusty, which almost always greatly reduces the service life. Only those who MUST be self-sufficient from the grid in winter should install a large wind turbine on a high tower. Solar systems, on the other hand, reliably generate over 25 -30 years electricity at approx. 3 to 8 cents/kWh.
A 4 to 1 reduction ratio would have probably worked just fine. Though I didn't notice whether or not you had slip rings installed on the mast head so the turbine could freely rotate 360 degrees without worrying about wire binding the turning radius? You could probably fashion a set of mast head slip rings off of another car alternator.
Hi there There ist a German man, Christian kuhtz, that is building exactly this Kind of Generator for decades.... He rewound the stator to be able to generate electricity at lower RPM.. Check Out His books called "einfälle statt abfälle" (ideas instead of Trash), dont know If this is a proper Translation.. Keep Up your Work dudes
Blade design is of most importance. Do more research on that. I have read that automotive alternators are about 50% efficient. Improving efficiency should be high on your list. Remember that torque X RPM = Horsepower Good luck.
Permanent magnet mach better use neodymium bar magnets .iyo need that regulator if you charging your car battery then connect inverters for your power needs
You need at least 36 pole pair armature winding for your low synchronous rpm. Instead of MFR or BRC or BSS regulator choose a LIN-type regulator and a LIN adapter you can set the lowest self excitation rpm. Good Job but you will never provide enough power with a regular car alternator.
thats an interesting alternator... a water pump on the back? so. excitation... if you have no field excitation, theres no COGGING at low speeds. but theres no power at low speeds anyway. wind power increases on the cube. if you can increase the magnetic field on the same cube to velocity, you can load the blades down to an optimal speed. regardless of wind speed. at the same time, the alternator output has to be matched for the optimum load. you can extract the energy at the same cube to velocity ratio as the wind, but you need a load that can absorb it. instead of throwing all the power of the wind away in a vain attempt to make "electricity", rethink the problem over. get out of the rut. water. it takes a lot of energy to heat water. a resistive load on an alternator creates heat. resistive heating is 100% efficient, but bare in mind that a proportion of the work, the HEAT, in a generator and load combination is also produced in the alternator itself. the current flowing through its windings is the same current flowing in the load. the load and the generator are a symbiotic relationship. they must be MATCHED. they rely on each other. without one, there isnt the other. if you made another one of these, applied these principles, and solely based it on heating water, i think you will find it will show FAR better performance than if you try to charge a battery. as water is a constant thermal, easily reproducible, heating a given volume in a given time gives a VERY good demonstration of power... though people are stupid and are more impressed by lightbulbs and flashing LEDs... what to do with heat? well now... what does a nuclear power plant and a coal fired power station have in common? whats an ICE run on? how do you cook? what do you do in winter?
Ok, First off great videos. But! Every time I see you using drill/drill press with out having the project clamped to the table makes me cringe thinking of the injury(s) that will happen. Not this time maybe, but it will. Please use clamps more often, if not for yourself for the young people watching these videos.
Great video shows the difficulty in pioneering and engineering things . Im Sure with gearing or modifications you can make it worthwhile . May is also ask what is the reason to choose an alternative over a motor / dynamo ? Thanks
OK buddy you got my respect - I detest what our politicians and global corporates are doing to our economies - via so called renewable energy....... For they are breaking what already works.... However we can counter their madness with vids like this...... And empower oursleves at least to some extent against their corporate madness....................
U tried shortcut way. U need to understand the engineering part of alternator. And also need to stay the wind speed so that u can calculate the design of blade size is required for the desired output when the wind is low. Try to increase the size of rotar n stator. Along with gear systems. Ur minimum rpm should be around 18-20 for better output.
The rewiring of the alternator is fine. The mehanical parts very profesional. But there are a few things thay might go wrong and you shoud adress to go ahead: *a car alternator generates best above 1500 rpm. At low rpm it could give to small power output.. A belt and pulley or gear mechanism will increase rotor speed *find the right size or the wind turbine to make capable to move the alternator at hig rpm under load. . The one you have seems too small *You dont explain how will the wires go down from alternator to charge controler or other control device wiihout get raveled. Some type or brush spinning mechanisms are used there

You could increase the slternator/wind rotor RPM ratio by interposing some sort of multiplying gears or, cheaper still, a bicycle chain and sprocket between rotor shaft and alternator.
This is not a wind GENERATOR, it is a wind turbine. A wind generator is a FAN. This thing generates electricity. Same silly thing as those solar generators: I've yet to see one generate a SUN.
Interesting. Why are you trying to achieve only 700 rpm when that would be tick over on an engine. Surely the best power output would be 28.8v at 1500 rpm taking into account that it's a 24v alternator - where as a 12v alternator provides 14.7v at 3000rpm? Just asking the question.
i would suggest to copy the design of a clip fan and make it in multiple phase 8layer by 4 neodymium magnets, back front and give it a bridge circuit , mine got 2kw an hour on a modest wind youll prob get 3-5 in your place
i understand you are in Karachi, so wind should be plenty but weather swing enough to take a toll on pully system. i would recommend a permanent magnet low rpm bldc motor as a generator. More wise on the page must be having more clear and advantageous ideas. for the sake of algorithm i put down mine. Regards and best of luck
If you drag water from uphill whit tubes to your house and use them on some pillars that tubes come to your house from above at height you can use m x g x h formula to produce energy with regular water that you use for house and garden , all you need is aerial tubes that bring water from uphill at height then tubes at 90 degrees could bring down water on a water turbine in your house and produce energy near your house whit the water turbine , pillars used need to be very heavy and that is all
There are alternators w/o voltage regulators built-in.. I want to build a wind generator but average wind speed is 1-8 mph where im at so its kinda worthless might build one for the hell of it.
I noticed you have solar panel and wind generator. Are they generating electricity separately and to different separate batteries? Or are you applying hybrid system for both?
Nice but a washing machine motor with a capacitor might be better all around everything from amps to turning speed you will have ac power so if charging batteries you simply have to hook up a battery charger!
Don't do any gearing! Direct drive is most efficient and reliable. If you need more power just get large e-bike motor or multiple giro scooter ones on same shaft.
I am looking for about your product place lace me a messages .When I post this .I am looking for more Information no this , how build one off grid much power put out .
Nice Idea, and you worked hard to get perfect Rpm to get sufficient voltage, I must suggest you that do not put the alternator directly on rotor blades, instead you must try a gear ratio. You should get the power from the turbine through a bigger pulley, than by gradually use smaller pulley upto 4 times. Than you can get the sufficient Rpm. You can use also the teeth pinions instead of pulleies..

If you can find an old series from the Discovery Channel called “The Colony” they do it in season one.
wish I'd thought of that .. ;) .. " charge a super capacitor " ..
At night?
@daveapplemotors that is the reason behind the super capacitors, but the solar panels are primarily intended to provide energy to the system for the excitation current during the initial period from a dead stop to operating speed. Once the system is generating power it will keep the capacitors charged. Now assuming that the capacitors become depleted after sunset, you can either have an auxiliary battery or a connection to the primary storage batteries through all relevant circuitry.
No car alternator is 24V. It must be of some commercial vehicle like bus or truck.
You can get 24v alternator for old chevy blazers.
@@Poorboychickencoop🤦🏻♂️. Man see the accent is indian so here in india we don’t get 24V alternator in any car and chevy blazer never came to india 🤷🏻♂️. Make sense before commenting
@@Elder650you think theyre gona search up if chevy blazers came to india? 😭
Nice to see utilising the basic idea of wind generation but for deep knowledge you should study further for optimum production with less power/ RPM of wind power.
Hi. The windmill was almost certainly too small to turn alternator fast enough. A car alternator needs several horsepower to deliver the watts. Alternators give about 350 watts, and assuming 30% efficiency that means a one-two h.p. propeller at least. Very skilled video performance, well done. Cheers, P.R.
You must be 127yrs old, you can remember the output of the first alternator installed on a production model vehicle and the phase out of generators in auto use. Tell me, was that soon after -ve earthing became the standard and 6V was phased out haha. Meant in jest, but seriously your figures are way off. Electrical load demand on modern vehicles now with bluetooth this, sync that, infotainment, screens, high power audio, heated everything from glass, arse, to mirrors, 2 billion times the computational capabilities of the Apollo moon lander and more ECU's than the space shuttle means alternators in standard 12V vehicle regularly approach and exceed 100A rated capability. I'm sure you probably don't need a maths lesson so I no need to throw power figures around except to say that's significantly more than 350W. That alternator was commercial 24V (not my area, light motor vehicle for me) so current rating would be inversely proportional for the same power, handy for that type of project working with less current . The vehicles generally have high electrical demand also (did you see the size of that sucker?) starting a high cc diesel and feeding a couple of 25kg+ 200Ah or so batteries, so I reckon if they shared the spec that thing is easy good for 75A, at a charging voltage of say 27V, so 350W?? Oh, and by the way, I think you underestimate the power of wind and fluid/aero dynamics. Yes is was rudimentary, but the spinny thing was plenty huge enough to drive it (with some gearing). Nearly 30yrs ago a friend used an old steel bladed radiator fan (adjusted pitch I assume) no bigger than 18" with a scrapyard alternator driven by belt mounted on the roof of his garage (come man cave), and a standard 12V starting battery as storage/smoothing/capacitance to run a CB radio and car stereo (maybe some lights, I cant remember) and in a mild wind it would power everything without draining the battery ;)
@@bobbobovich4356 Hi Bob. Well done, I'm 128 next birthday. It's all candles and a ruined cake for me.
Too much irrelevant stuff in your post, mate. F.Y.I. the power available from any windmill is proportional to the CUBE of the airspeed passing through it. It's the VOLUME of air that does the work, volume being a cubic measurement. The one in the video would run the alternator nicely in a category five hurricane (about 256 kph), but quickly self destruct. At normal wind speeds it wouldn't rip the skin off a rice pudding, there's not enough kinetic energy in the small volume of air passing through it per second. Gearing it up won't help. Try pedaling a bike up a steep hill in high gear if you don't believe me.
Before eager beavers spend their hard earned money on a dodgy project, they should understand the cube law importance in windspeed, because it limits the maximum energy available. Commercial wind generators only work because they have huge volumes of air passing through. Now excuse me, I'm off to finish a homework project. Cheers, P.R.
A 100 watt car alternator is heavy duty, right. 350 watts?
@@daveapplemotors Hi Dave. Good point. Wattage varies with requirements of the vehicle. My "ballpark" figure of 350 watts probably applies more to a bus or long-haul truck generator running extra lights and air conditioning. My point that you can't get any more power out of an electric generator than its power input (vee belt, windmill) puts in is correct however. Inserting gearing between the drive and the generator will not increase the amount of power that can be extracted. If it was possible, perpetual motion machines would be exist. Cheers, P.R.
Unfortunately i saw your video is very late
I appreciate your effort the way you make all things
Excellent idea and performance
If u use permanent magnets on the rotor u will get your required voltage at a much lower rpm. No need for gears. As long as it's a strong 🧲 like n52
Well said mate 👍 and it's hard to rotate the blades if they add gears, better with Permanent magnets ;)
Yes we are looking for these magnets, hope to find the right ones soon and get the next part .
If I'm not mistaken the hoverboard motors u used in previous vids have n52 mags in.. try removing them. Or. Being a diy channel old hard drives.. they each got 1 in. . And they should be wide enough for that stator
i ues a leg of leg of one of the phase of the sate in rectifier & Now dc in to a copastor & back to the the burses & from the negative brush to the body of the alternator as the wind pick's up the alternator grows in speed & Bild charge in the run copastor delivers a steady voltage to the rotter as the sped increase's the prudish charging amps, An option is is to clang the copastor for vibrating pint regulated this works well & that will provide a regulate dc current to the rooter only . if we are to charge at a dist. To a bank of batteries , we should modify the stator in to a 3 phase to a Y stat that can travel the distance to the battery bank & the rectify at battery bank .
A car alternator was never designed to operate efficiently at low rpm.
Your windmill attached to it can not produce significant power.
If I make a turbine with an alternator using a separate battery, can I use it for many years?
What you need is some sort of device to stop it from swinging in the wind when you go up on the roof to do maintenance.
One gust of wind in the wrong direction and someone loses their face.
The easiest way is changing the rotor to a permanent magnet rotor instead
On rotor, by grinding /make space for magnets we can do..
. But question can we put magnet (in two parts) from magnetron of microwave.. Do u reply for experience
@Raga - No, that is not easy.
Proud of you guys, Pakistan zindabad

Which car alternator you are using ?
Thank you guys, this is great stuff, wonderful information and very good and clear presentation. All the best, keep going !
Your English is fine ! Don't worry.....your doing great!
Thanks bro
It so much fun and knowledge seeing you guys working, keep it up
Love your channel but I was waiting for the end result.
Why not try a 24 Volt ALTERNATOR and see the difference ?
Respect from South Africa.
Only thing I would do differently is just use strong magnets to create the magnetic field so you’re not relying on an external battery source. Other than that I think you did an awesome job.
explain please.
How to use strong magnets
Habéis hecho un gran video y un gran trabajo que selo habéis curado, creo que lo único que os ha faltado es montarle en el rotor de 4 a 5 imanes de deodimio , en una posición de norte sur norte sur y hubiera aumentado el voltaje y el amperaje, enhorabuena por el trabajo realizado, un abrazo
Great video for educational purposes but is there a part two to see if you nail down the blade design and got enough RPMs to charge batteries. Saw some solar panels so wondering if this works in conjunction with solar panels as well
Thanks in a million. Great content. Awesome imagination. Grade: A++💥
👍👍
First time I am seeing a video, which truly says that the expected voltage is not achieved so more (research & trials) are needed.
Truly appreciate it.
Dr NPSingh ONGC Dehradun
Don't most people that use car alt use a gear reduction to spin the alt fast enough to produce power?
Would a stepper motor used as a generator give more power? I would think whatever you use it will be necessary to gear up the windmill rpm. Very good video.
Guys you bring a lot of motivations for create! Thanks from México.. Why this time did you choose 5 blades in the design??
This installation is very dangerous due to thunder strike, no surge arrestor or ground facility not installed at your working sight , its can cause damage your property or personal injory-
Well build Dude keep going... to work better than what we expect 👍
Guys maybe you could show exactly what you're doing, when dealing with electric stuff, point at it and explain what needs to be done ..just pointing a camera in a general direction and give general description is ...frustrating. Unless that's the purpose...? Otherwise, great project..
Yes you are right, we added these shots for better explanation and will try to improve them using a pointer next time.
@@DIYKingSaM Awesome 👍
It would be easier, and even economical, to take advantage of the brushless motor of an electric scooter wheel, of which they are an integral part of the wheel, it would generate three-phase voltage, so you put a regulator-rectifier of the kind used by motorcycles with large displacement, and you would have regulated DC voltage ready to charge a 12 volt battery
just change the motor you are using and it choose the right one for that RPM you are getting
Awesome project! I am finally learning about permanent magnet brushless ac and dc motors. Even though I have raced rc cars, built and fly drones for years i just started learning about this and I love it!
Estupendo pero una pregunta, ¿Tiene la capacidad de girar 360 grados o le pusiste algun tope?..... para que no se enrede el cableado????
Why didn't you consider the windspeed in your area and calculate the windmill rpm ? and then check peak rpm for alternator to generate max voltage and then derive the gear setup to increase the rpm to the alternator. With a gear box, it's impossible to use a car alternator. 10/10 points for effort. 1/10 point for engineering
Hello I have solved your problem if generating. The rpm you need for any project that you are doing.
I had put out a video a few weeks ago and was not going to share my secret until some tim .
In a few days I will tell all my secret in how to generate 100 times more efficient from your alternator windmill and much much more stay tuned and please give me a thumbs up and I like as I will share with you and all on UA-cam My secret
Awesome - costs involved ??
Too much ...
I tried this once and was able to get a decent amount of power from a similiar setup. Gear ratio is definitely a game changer. I winder if there is a way to have variable gear ratio depending on the wind speed… i dont have an answer for this yet 🙂
A cvt transmission is the best option, the simple version that uses no control circuitry, is commonly found in snowmobiles while there are automotive versions. But with the right application of a snowmobile clutch/ cvt pulley is the easiest option that i can think of.
Put on a heavy flywheel , use some external power to get it going first.
That's my theory anyway!!
What's your gear ratio? Acquiring Planetary Gearbox seems tricky. Check out Archimedes blade of Liam F1
13:40 the blade seems to move on the opposite direction of the angle of attack. And also I don't see that much wind gushing since the nearby objects are pretty much stationary.
Don't get me wrong, it's a doubt. Will be happy if you cleared it out. Btw love your workshop, wanna build one myself. 👍🏻
why not source some other ready made suitable alternator/generator. i have heard that stepper motors also make good generator. Actually this technology is need of the day as halala modi is making pre-meters and that type of rubbish controls. these is a viable business opportunity of made cheap.
Great Video! You are right to worry about RPM, a car alternator needs to turn at 3500-5000 RPM to achieve its full field amperage. If you are not looking for peak amperage but instead voltage, use an overdrive mechanism through a planetary gear box and ensure you are using a WYE type stator in the alternator. I daydream about making a wind powered alternator generator and appreciate that you did the work to see it through to the end.
Indeed, your thoughts are worth reading. I hope you will soon get your hands dirty building one.
We love to get such comments and that's why we together with you all bring this channel to the best possible projects that we can
Hi guys it is of very good job but I do not know what is the wind turbine, if you have any good of generating more power you can become a new company to sell your product on a lower price so that every Indian can purchase.
Use one from a diesel - these run at half the rpm :)
@@wombatg0 Really???? I would love to see you try to back up your comment. Just for comparison, the alternator pulley ratio on a Cummins Diesel is 3.22 which equates to an alternator RPM of 8,050 with an engine RPM of 3,000. Typically, The standard automotive gasoline engine alternators have their full output rated at 6000 RPM but can continue to spin up to 12,000 RPM or more without any additional increase in output.

Here you need to design a new generater with maximum number of poles , say 12 or more, could achieve high power output in low RPM.
Where is your DIY workshop, I wanna come over to see.🤩. Have same interests. Great work
*What for?!? All practical tests show that small wind turbines hardly generate any electricity,* because hardly any wind blows close to the ground.
*With solar panels, you can generate at least 20 to 30 times more green electricity with the same investment!*
Moreover, the wind is extremely gusty, which almost always greatly reduces the service life. Only those who MUST be self-sufficient from the grid in winter should install a large wind turbine on a high tower. Solar systems, on the other hand, reliably generate over 25 -30 years electricity at approx. 3 to 8 cents/kWh.
Assalam_e_Aliakum you make a video of your all instrument you can homemade and readymade
Hey guys great project!
Great try!
Your skills are masterful!
Be proud of what you accomplished!
Can't wait to see 2.0 !
Subscribing to this. Wanting to build one. 😊
A 4 to 1 reduction ratio would have probably worked just fine. Though I didn't notice whether or not you had slip rings installed on the mast head so the turbine could freely rotate 360 degrees without worrying about wire binding the turning radius? You could probably fashion a set of mast head slip rings off of another car alternator.
No, do not use gears.
Hi there
There ist a German man, Christian kuhtz, that is building exactly this Kind of Generator for decades....
He rewound the stator to be able to generate electricity at lower RPM..
Check Out His books called "einfälle statt abfälle" (ideas instead of Trash), dont know If this is a proper Translation..
Keep Up your Work dudes
Blade design is of most importance. Do more research on that.
I have read that automotive alternators are about 50% efficient. Improving efficiency should be high on your list.
Remember that torque X RPM = Horsepower
Good luck.
Permanent magnet mach better use neodymium bar magnets .iyo need that regulator if you charging your car battery then connect inverters for your power needs
you needed a gearbox. no way you're getting 700rpm out of those huge blades just from the wind
You need at least 36 pole pair armature winding for your low synchronous rpm. Instead of MFR or BRC or BSS regulator choose a LIN-type regulator and a LIN adapter you can set the lowest self excitation rpm. Good Job but you will never provide enough power with a regular car alternator.
thats an interesting alternator... a water pump on the back?
so. excitation... if you have no field excitation, theres no COGGING at low speeds.
but theres no power at low speeds anyway.
wind power increases on the cube. if you can increase the magnetic field on the same cube to velocity, you can load the blades down to an optimal speed. regardless of wind speed. at the same time, the alternator output has to be matched for the optimum load.
you can extract the energy at the same cube to velocity ratio as the wind, but you need a load that can absorb it. instead of throwing all the power of the wind away in a vain attempt to make "electricity", rethink the problem over. get out of the rut.
water.
it takes a lot of energy to heat water.
a resistive load on an alternator creates heat.
resistive heating is 100% efficient, but bare in mind that a proportion of the work, the HEAT, in a generator and load combination is also produced in the alternator itself. the current flowing through its windings is the same current flowing in the load.
the load and the generator are a symbiotic relationship. they must be MATCHED. they rely on each other. without one, there isnt the other.
if you made another one of these, applied these principles, and solely based it on heating water, i think you will find it will show FAR better performance than if you try to charge a battery. as water is a constant thermal, easily reproducible, heating a given volume in a given time gives a VERY good demonstration of power... though people are stupid and are more impressed by lightbulbs and flashing LEDs...
what to do with heat? well now...
what does a nuclear power plant and a coal fired power station have in common? whats an ICE run on? how do you cook? what do you do in winter?
Ok, First off great videos. But! Every time I see you using drill/drill press with out having the project clamped to the table makes me cringe thinking of the injury(s) that will happen. Not this time maybe, but it will. Please use clamps more often, if not for yourself for the young people watching these videos.
Great video shows the difficulty in pioneering and engineering things . Im
Sure with gearing or modifications you can make it worthwhile . May is also ask what is the reason to choose an alternative over a motor / dynamo ? Thanks
OK buddy you got my respect - I detest what our politicians and global corporates are doing to our economies - via so called renewable energy....... For they are breaking what already works.... However we can counter their madness with vids like this...... And empower oursleves at least to some extent against their corporate madness....................
U tried shortcut way. U need to understand the engineering part of alternator. And also need to stay the wind speed so that u can calculate the design of blade size is required for the desired output when the wind is low.
Try to increase the size of rotar n stator. Along with gear systems.
Ur minimum rpm should be around 18-20 for better output.
The rewiring of the alternator is fine. The mehanical parts very profesional. But there are a few things thay might go wrong and you shoud adress to go ahead:
*a car alternator generates best above 1500 rpm. At low rpm it could give to small power output.. A belt and pulley or gear mechanism will increase rotor speed
*find the right size or the wind turbine to make capable to move the alternator at hig rpm under load. . The one you have seems too small
*You dont explain how will the wires go down from alternator to charge controler or other control device wiihout get raveled. Some type or brush spinning mechanisms are used there

You could increase the slternator/wind rotor RPM ratio by interposing some sort of multiplying gears or, cheaper still, a bicycle chain and sprocket between rotor shaft and alternator.
This is not a wind GENERATOR, it is a wind turbine. A wind generator is a FAN. This thing generates electricity.
Same silly thing as those solar generators: I've yet to see one generate a SUN.
Interesting. Why are you trying to achieve only 700 rpm when that would be tick over on an engine. Surely the best power output would be 28.8v at 1500 rpm taking into account that it's a 24v alternator - where as a 12v alternator provides 14.7v at 3000rpm? Just asking the question.
Explain how you can get the blades to spin at 3000 RPM ....
i would suggest to copy the design of a clip fan and make it in multiple phase 8layer by 4 neodymium magnets, back front and give it a bridge circuit , mine got 2kw an hour on a modest wind youll prob get 3-5 in your place
i understand you are in Karachi, so wind should be plenty but weather swing enough to take a toll on pully system. i would recommend a permanent magnet low rpm bldc motor as a generator. More wise on the page must be having more clear and advantageous ideas. for the sake of algorithm i put down mine.
Regards and best of luck
If you drag water from uphill whit tubes to your house and use them on some pillars that tubes come to your house from above at height you can use m x g x h formula to produce energy with regular water that you use for house and garden , all you need is aerial tubes that bring water from uphill at height then tubes at 90 degrees could bring down water on a water turbine in your house and produce energy near your house whit the water turbine , pillars used need to be very heavy and that is all
Now you can power your toaster! lol
No.
There are alternators w/o voltage regulators built-in..
I want to build a wind generator but average wind speed is 1-8 mph where im at so its kinda worthless might build one for the hell of it.
W⁰W way t⁰ G⁰ guYs!! Grate job. These guys just made a tubine for $150.⁰⁰ verse buying one for 10k.

good video.
megnat rotor is better.
Hmmm i wonder if you could get the rpm you want with something easier to spin and then maybe transfer through some gears/chains to the alternator? Idk
I dont understand that why do you used the 12 volt battery thats providing 30watts of power plz discribe me
Don't do any gearing! Direct drive is most efficient and reliable. If you need more power just get large e-bike motor or multiple giro scooter ones on same shaft.

Nice Idea, and you worked hard to get perfect Rpm to get sufficient voltage, I must suggest you that do not put the alternator directly on rotor blades, instead you must try a gear ratio. You should get the power from the turbine through a bigger pulley, than by gradually use smaller pulley upto 4 times. Than you can get the sufficient Rpm. You can use also the teeth pinions instead of pulleies..
No, do not use gears.
