• Building an Alternator...
PART 3:
• Building an Alternator...
In this video I will be showing you how I converted this old alternator into a motor for my electric go kart. The only reason I chose this alternator is because it only costed me $20 and it was still in fairly good condition (any 3-phase alternator should work!). I I ended up wiring this motor in a delta configuration. Originally I was planning on comparing the motor when wired in a WYE configuration vs the motor wired in a delta configuration but I will need a more powerful battery pack before I can do so.

This reminds me of the early days of gas powered cars where my Dad would tell me about going to the junk yard and taking scrap cars to create stock cars, race them and improve them which later led to muscle cars and more innovation. It’s like we’re seeing it again only with EVs.
My dad was a mechanic in Mexico. I saw him did so many engines n shit in our garage. Good times.he had a super B moppar and I dindt knew wat it was.
My father did this. Had a 7 second n/a bug in the 60-70's. He told me all the crazy stories. Chainsaw boats, go karts. Building cars for all kinds of thing from drag racing to demo derby. Wish it was that easy now days. I felt awesome when I turn a vertical shaft motor to a horizontal shaft. Showed my dad and he was like yeah that's the stuff we did. It was a better time back then. As a mechanic and auto body tech I'd prefer the 50's
Bateries aint cheap tho ....
QAAAÀAAÀÀo
MY father was a birdwatcher! *sigh*
As a VERY old mechanic. Its pleasant to see a person(no insult intended) who is a 'geek', but not afraid to get his hands dirty. Very interesting video. Thanks. I enjoyed it.
Person? What an insult... just kidding.
@@sir_john_hammond I think he ment about the "geek" comment. Me personally I would take it as a compliment.
Thomas Furmanek yes, just poking fun at his choice of word order.
@@sir_john_hammond after rereading papasmurfs statement I see what you are saying.
old mechanic here too ... wish someone would have told us we're going extinct
With young people like you, we can have hope for the future. Good luck kid .
There's one of him to every hundred kids with no discipline who live in their cell phones who think communism is perfect and that it just hasn't been done properly yet. *sigh*
as a senior citizen who worked in the auto industry my whole life, I thing its refreshing to see young people today with ingenuity, instead of sitting around on cell phones and complaining

Hugh Jaanus
Apt name. At least you're honest about it.
Hughie, sort of a figure of speech. There was a time in the civilized world, when people, were expected to go to school, get an education, peruse a working career, buy a home , raise a family. Then most would retire. The time spent working was referred to as your Work Life. Believe it or not , people wanted to work hard so they could have a home, a family. Not be living in their parents house til they were thirty five. Lives were , Birth.... School.... Work.... Death. We even wrote songs about it. Then it went all Beavis and Butthead as the norm
@@billbethel8375 people still do this, it's just that nowadays we don't have the huge economic boom leftover from the war and the GI bill, in addition to lower wages when compared to productivity. It's not as easy to get by when you can't get a good job, and then if you do, you still can't afford a house and a family, let alone enough money to save for retirement
Tbh no old folks wanna take the time to reach anyone anymore.
I can never understand dislikes on videos like this.
Brilliant video and excellent craftsmanship sir!
To some, if it doesn’t use gas it’s bad!
Some folk think disliking will remove these types of videos from their suggested videos.. so most likely nothing personal against this guy or the cart..
Well actually continued usage of that construction as it is, would result in the catastrophic failure of the batteries, which would catch fire or even explode. Not pleasant. I know what you mean, but some negatives are probably down to that. It's a dangerous design.
Bad soldering jobs give me seizures.
Some people don't like annoying music over work like this
What a brilliant and good man. Someone who actually likes to use his mind, create things and not afraid of work. Best wishes to you.
Amen
Gaaaaaaaaay
This is really cool! I can see myself now, flying around the neighborhood on my cart! I built a few race cars, hot rods, and worked as pipe fitter, but, I never thought to use an alternator as a drive motor. This was great. Thanks for posting.
Good video! In 1957 I had a home-made gas go kart & our Dad built a really simple generator driven go kart with my younger brother. No mods needed on the generator. Three 2x4s made the "frame" & 2 axels - steering with feet. Dad made a 3rd battery post out of solder in the middle of a 12v battery. (Batteries then had visible straps connecting the cells, covered by a tar substance). So you could run on 6 volts (about 5 or 6 blocks) at good speed. Then switch cables to the other 6 volts for the trip home. I'd run on all 12 volts & it was almost too fast on that little kart w/ skinny solid rubber wheels!
I discovered your video a few weeks ago and only had time to revert again today. Well thought out young man, I'm not an electricity wizard but I give you straight A's for innovation, it's excellent !!
I did essentially the same thing when I was in grade school in the 1960's, using a mini bike, gears and chain from an old Honda motorcycle, an alternator from a 1950's model Ford (I'm not sure what specific model or year) and a "Juice Box" car battery, and it worked. However, doing this in the 1960's, using 1950's parts, it was anything but efficient. It would take all day to charge the battery, but 10 minutes to use it up.
_But I sure enjoyed those 10 minutes..._ :)
What a cool project. I would have loved to do this when I was young. I am impressed at the quality of your production too. Very clearly explained and demonstrated. I hope it inspires young engineering-minded people to get out and create something themselves. Thumbs up.
Thanks for posting. It's really going to help me with a mobility cart for my wife. My plan is to use a quad rolling frame as the base with suspension, and the ability to get out in the yard, as well as shopping. I plan to use 2 - 12 volt standard car batterys in parallel for low center of gravity and more run time.
Heard of an electro mechanics chair,,,(copy, and assisted mobility,,,
Thank you , its refreshing to see a young man using his brain for his great project .well done
I can tell you now that austiwana is a Spherical Earther without even asking him. How do I know ? Because he's educated. How do I know he's educated ? Because he understands delta and star motor windings. But seriously . . . You gotta give it to this young guy. He has presented this project in such a cool style. There's no arrogance with any of his presentation. Love your work !
PS: I have no idea why this would attract so many thumbs down. I just don't get it.
I have shared this with a friend who is an electrician, a huge nerd, and who is always looking for new projects. thanks.
Great job. So good to see someone of your generation being so creative and loving using your head and your hands. You give us older creators hope. Been enjoying creating and building all my life and I am 71 and still at it. I have subbed.
Watch out u old fart some smart arse gonna think u were born-a-building! Lol, Coming from aold 75 yr-old builder/fixer,,, lol
*NICE!!!!*
I made an EBike with a 100 Amp alternator last year.
It tears along at 18KPH on a 14V battery, and uses 15WH per KM.
Watt's cool is that it is soooooo quiet, it is recharged by solar panels - and it is such a pleasure to ride :) .
Keep up the good work bro.
15Watt hours? or 15 amp hours? big difference on a 12/14volt system
Howdee Andrew,
1 Amp hour at 14.5V - is 'watt' this bike consumes when it is traveling on a level path at 18KPH.
It travels 4KM per 4AH battery, if I run them flat, but that's not such a good idea with these LiPo cells.
I could make it go faster, with a higher DC supply voltage, but there comes a tradeoff between speed and range, so I have opted to settle for this rather sedate 18KPH speed :) .
Braking?
Braking is partly done by the alternator, but mostly by the bike's existing brakes.
+Perkins_RC76
If you can walk at 7 mph, I would like to see that.
Maybe make a video of it?
Maybe become an Olympic race walker?
The true walking speed is closer to 3 MPH, so my 12 MPH bike is a LOT faster than mere walking speed :) .
My kids think I’m awesome because of you brother - you’re a gem 💎
Cool! Lots of good points about alternators, controllers, and over-discharge of the battery. Very nice bg music all the way through. Going to watch your drift trike video to see what points you make about battery management of the Li-po. Always interesting haha!
Heh heh heh
When I tried this out I found it alot easier to use old GM alternators rather than newer ones. I found that newer ones are a pain in the ass to disassemble, And on some brands the diod pack and brush assembly are in one piece so you have nowhere to solder some wires to to feed power to the rotor.
The world needs more people like you. Don't be disheartened by negative comments. Keep going. Keep trying new things. Keep questioning. Do not allow anyone or anything to hold you back. And please, also look after yourself. Invest in some elbow length leather welding gloves for when you're working with that angle grinder. They are great tools, but very quickly make a mess of human flesh.
Thank you for thoroughly explaining how to use delta configuration, and the controller to use. That part is always left out of vids. Now I know! Thanks
As a mechanic, I'm so glad to see a person such as yourself being creative and making something out of relatively nothing. When others your age are infatuated with call of duty in their parents basement, you'll be building a great life yourself. well done, and don't let up!
People this guys age would probably love to be doing stuff like this. Not everyone has 15k worth of tools and place to do it though. COD? Costs a $150 console and a free game. Lot easier to get into.
All I gotta say is if we had people like you good sir in charge of this country leading, we’d be in a much better place!
I love seeing someone fabricating something unique! Great job!
Well, I guess you could say that is one alternate way to power a go kart.

Sweet project!
A side note for the alternator:
You can also leave the diode bridge attached and have the DC output feed back into the field windings of the rotor. That way you don't have to have an external DC supply.
Bullshit dude. Do you not know the purpose of a diode?? Ya, they only allow electricity to flow in ONE direction. That is the sole purpose of diodes.
@@JM-yx1lm you easily used BS when in fact you don't know what he mean or you just had a very little understanding on how the system was wired.
You all don't know what your talking about. You wire the diode in series with the bridge rectifier opposite of the primary phase Feild winding. The other fields you wire in parallel. Besides the resistor on the commutator only puts out 5 milliamps. 😜
@@JM-yx1lm Diodes have many purposes, unidirectional current flow (under 'normal' conditions) is only one property (although a universal one). LED, zener, tunnel, schottky... and some of these are useful precisely /because/ they conduct in a 'reverse' direction.
A 40A fuse is designed to carry 40A not blow at 40A. Potentially it could carry 60A for nearly a minute.
Uh not normally. A 40 amp fuse can carry about 32 continuously
@@STRUTZKOFF As a retired ASE Master Tech, I can tell you that fuses are thermal devices. So they can open at 32 amp in a hot engine bay or 48 amps in a cooler cabin. These are sensitive to temperature and not so much current. I have a two page sheet that cover newer fuses starting with the ATC/ATO and up, but explains how they work, where they get their names, usage and a temperature chart from ACDelco.
@@STRUTZKOFF
Fuses protect against surges not against continuous power
Perfect idea. One of my alternator ball bearings was making my car sound like a tank. The recycling refund was $10 Canadian, so I figure it would be a waste to scrap it... So here I am
When joining wire ends untwist both ends and then slide one end into the other and twist them together. Essentially braiding the two ends together. Then apply solder and allow it to wick the entire way. Solder is not glue and using it to "adhere" one wire to the other creates a brittle joint that will come loose with vibration and time. Cool project though.
"and then slide one into the other" - I know (I sense) you mean well, but this particular passage would need either more words or hopefully a YT video showing the technique. Thanks though.
CriticoolHit lead solder should be fine. It thermal expansion and contraction that typically causes cracked solder joints, not mechanical vibration.
This guy is lucky he got the direction of each stator winding correct, because there is no way that 'start' and end' of each winding set can be determined by a simple continuity test. Too easy to have 2 in correct same direction and the 3rd in an opposing magnetic field orientation. This MATTERS, be it star or delta connected.
So, solder if done correctly, might be good for a test, given the equipment to correctly determine this magnetic field directions isn't a garden variety instrument. BUT it's a pain... easier to use insulated screw tunnel connectors [the type electricians use in house wiring]. Once proved correct the far better way is to use a crimp connector, NOT dodgy solder as seen here, for the solid stator conductors to the flex cable. CRIMP connections if done correctly are always far better than solder in an automotive application prone to vibration like this.
Frankly, the best way would be to take each stator winding to a 6 terminal block mounted on rear of the alternator rear housing and then bridge however you want [star or delta] and terminate the flex leads there.
Cool project!
I am an electrician and I have always been told that the motors we wire are wye delta induction motors.
The induction winding is wye because the voltage is better over a longer distance but the the actual run winding is delta because it delivers more torque.
I would think torque would be desired on your drift trike.
I am anxious to see it.
Hi, can you explane me has alternator a brushed dc motor or brushless dc motor? in vids. 3:05 he said we put brush to the place but he used brushless speed controller. If I use alternator, What kind of speed controller I should use?
@@cahitabdullahmisirli8424 Alternators are a milestone piece of technology, and uses some clever technologies to achieve what they do. A typical DC brushed motor uses an arrangement of permanent magnets on the stator (around the outside) with two or more electromagnets rotating on the central shaft, and whose polarity is switched to ensure each electromagnet opposes the stator magnets. With me so far?
An alternator, on the other hand, just flips the concept inside out. Now you have coils for the outside stator with an electromagnet on the central shaft which gets DC power through a pair of slip rings and brushes - the rotor's magnetic/electric polarity is not switched with rotation as it does when using commutators.
When vehicles used generators for power, the speed of the engine would cause wildly-variable output voltages that were difficult to properly regulate. The alternator changed that, varying rotor speed was no longer a problem because very precise voltage-regulation is done by simply varying the voltage going to the rotor electromagnet. The strength of the rotor's magnetic field controls the energy induced into the stator's windings, and can precisely control the output power.
In this project, the DC power level of the alternator's rotor would be held constant, while the stator windings would be sequenced with varying speed and power levels to spin the output shaft accordingly.
Thank you for showing us your cool project! I have just become curious about how much you can really use an alternator as a motor practically and this video is encouraging. So thanks!
I wish that dude was my neighbor 😁
I just imagined having him standing with the same face he have all the time in front of camera, just looking at me waving.
After over a year, I finally chose to take this video off Watch Later. It's cool how you turned a *car* alternator into a motor for your electric go kart.
This is great. My alternator happened to be the 6-wire, like his. His video got it all figured out
You should connect a brushed DC speed controller between the lipo and the field winding. It gives you a very easy, simple and cheap way to vary the field current and thus the magnetic "gearing". High field current gives you high torque but low speed (due to big back-emf). Good for starting off and climbing hills. Low field current is for lower torque and significantly higher speed. Would make the setup better performing for very little extra cost and complexity. At these levels of power and voltage even an ESC designed for an R/C model can be used, and a simple "servo tester" can be used to provide the ESC with the "throttle" signal.
Is this why many motors have a centrifugal switch? I knew position 1 was for torque and position 2 was for high speed but I didn't know the theory behind how it worked. But I think my example demonstrates what you are explaining. Im on the verge of a Eureka moment when it comes to electricity, I just need to keep trying. Im a master at engines and mechanical things, just not electricity yet.
@@SquillyMon It might be, but depends on what kind of motor and implementation. Some AC motors, like large ones for air conditioner compressors, have a start capacitor they use to initially spin up the shaft. Once they reach close to running speed, the centrifugal switch takes the start capacitor out of the circuit (best research it on google books because hard to explain without diagrams). On some DC motors that switch can do many things - for example the field coil and rotor coil could be wired in parallel for starting (so high field current and high torque), then switched to series at higher speed (so lower current, lower back-emf and hence higher possible speed).
These days I don't think centrifugal switches are that popular. You can do a lot more using electronic control, which makes a mechanical switch kind of obsolete except in special cases.
Understood... The last example I saw was on a clothes dryer... I'm familiar with the capacitor start motors i.e. on my large Air Compressors. I literally dream about one day being able to think outside the box with electricity the way I can with machines/engines etc... Mechanical Mastery I've got. Electricity?...not even close.
Can you recommend any books or videos that might be able to give me a good foundation for electricity? I consider no material too simple...in fact, since I'm a simpleton, I'd like to start with simple. I actually just read from a book from the 1800's about Teslas many theories, A/C-D/C current, poly-phase motors etc...but it started to get over my head in a jiffy. Also another book from 1962 targeted for teaching 4H GIRLS about electricity!! LOL, They were actually quite informative... I don't care where the info comes from because its all good stuff in my opinion. As long as my curiosity fuels my desire for knowledge, I know I will become more proficient, because you have to stay curious!
No idea about books of the level you're looking for (I'm a mechanical engineer, not electrical, so my own textbooks are rather simplistic). The howstuffworks website was useful to me to get learning the basics but there are other, more dedicated websites that will teach you in greater detail. Here's one that describes the various methods of starting a single-phase AC motor (one of which is the capacitor system I mentioned in my other comment): circuitglobe.com/starting-methods-of-a-single-phase-induction-motor.html
Lots of good resources and info on that site. It's technical and complete, but not too complicated to follow along.
I really appreciate you taking time to respond, I will check it out!
The world is yours, go get some 👍👍👍, you have great enthusiasm and so on expressing how it is good job champion
I have watched many videos alternator to bldc motor most of them had 3 wire or 4 wires coming out of the coil which did not help me as i had 6 like yours. Thank you for excellent video with step by step instructions.
Your battery terminal most likely melted because the screw/bolt was not sufficiently tight. This causes the joint to have a high resistance. The power lost in the high resistance joint (R * I^2) will cause heating in the joint. At higher currents a loose joint can get hot enough to catch fire.
If you can rotate the lug/wire on the bolt using just your fingers, it is too loose.
I bet he is smart enough to know that. I'm for the high discharge rate.
@@bbstacker70 the motor and controller wires all have much smaller cross section than the battery terminal so they would burn up before the battery terminal. He also only shows one terminal burnt. If it was high current through the battery, both terminals would be similarly burnt.
Very cool. The camera work was good too.
less handsome guy in picture will be even better 8))
...And that´s why we don´t use car batteries, designed to provide a huge load for a short period of time, to provide continuous power, people.
Buddy, thanks for uploading this!. I loved the simplicity of what you just did. I´m thinking seriously now in trying an alternator to power a small enduro, but using AGM instead of conventional lead acid...
Smart, good looking, and apparently healthy. I am an old dog so I didn't catch a lot of what you were saying. But it was cool to watch and very refreshing to see a young person with such positive qualities.
Punchable face, eh?
Great job dude.
Your new title is "Alternator Meister."
Drive safely.
Nice touch adding the keyway to the motor output.
I learned something new by that bit of workmanship
Yep. People don't realize that although an alternator is an electric motor for the most part. There is still a 6 diode pack that prevents current back feed. Also called a rectifier. Essentially a diode only allows current to flow in one direction. A/C or alternating current is what an electric motor produces once spun. Alternating current is electrons moving back and forth at a specific frequency. Since batteries need direct or D/C current. A diode is used on an alternating current flow, to only allow the movement of electrons in one direction, and block the reverse directional flow. Thereby creating direct or D/C current output by the electric motor, which is now an alternator, if spun by some form of propulsion. Gas or diesel powered engine, wind blowing over a propeler, water flowing over a paddle wheel, enriched uranium 235 placed in close proximity to more uranium 235 with a specific critical mass and a moderator like graphite or heavy water to slow the flow of neutrons to generate heat and then steam to turn a turbine, or even someone peddling a bike with a chain ran to the alternator. Anyhow... outstanding engineering my man. Except for that minor restriction issue. But overall that is a minuscule adjustment, which is all part of the perfection process.
So you missed the part where he removed the diodes?
Hahahahahaa lol imagine enriched uranium under the seat, maybe 10 grams wont be as lethal
Ed
Well said and nicely critized.
Well Ed, don't you 'wanna' look like a smart ass! What were you "pulling", during the early section of video where the author removes the diodes?
and.... "D/C Current" Ed? Try "D.C." (indicating abbreviation for Direct Current) or just "Direct Current". Your suggestion of a "Direct/Current Current" is a flog!!
and.... Also Ed, your statement "A/C or alternating current is what an electric motor produces once spun" is BULLSHIT, FAKE and a total CROCK OF SH*T. A DC motor (yes Einstein, THEY ARE ELECTRIC MOTORS), when spun via an external power source will produce D.C. (Direct Current), suitable for charging a battery or powering other suitable electrical equipment, via voltage regulation. So, get your facts right and leave the author in the video alone, for a video/project well done.
@@gingerbread2875 Escuse me Ginger How Many Diode do You remove, four or Six,. You are Very smart Man...

This is really cool. Great content, well edited. You have a great way of explaining things. My son was super inspired when he saw this video. We have built a gas go-kart in the past and the kids hacked a scooter and made a low speed high torque trike out of the parts, but this is pretty cool and economical. Excellent video, Please keep up the good work!
I agree... I'm a little behind on the electronics but I hope this young man keeps up the good work and stays humble. the world could use a few more leaders like this guy.
Great stuff, my fumbling accidentally hit thumbs down , sorry
Outstanding young man....Canadian ? I say that without reading below because he talks so clear and logical.
When he's talking to the camera it reminds me of talking to someone in Elder Scrolls Oblivion
The uncanny valley is lovely this time of year
Reminds me of a ThunderBird marionette.
For anyone looking for easy, cheap and burnouts.
Just use a Toyota gear reduction starter, and dont use a controller, use a Ford starter solenoid instead, And a classic car horn button for the throttle.
As soon as you hit the horn button, your kart will be sideways and scare the shit out of you.
This method is by no means reliable, and probably unsafe, but it worked well for me and didn't require and modifications.
These parts can replace buying the module controller, motor, and throttle?
@William Giglio Would be nice .. id like to get more info on it.. .can you direct me to it? i'' appreciate it... so far i got some alternators converted already...
The controller is converting DC to AC , alternators are essentially 3 phase AC motors. Hence the name alternator
Didn't know that gas soldering iron held enuf heat for big wires! Great vid! Thanks!
brazing is pretty strong but its definetelty not welding :-)
You must be an electrical engineer, amazing
That was excellent on so many levels. Great job and fascinating to watch. Thanks man!!!
It is indeed fascinating ! Keep up the good work!
omg you're a genius! I thought...theres no way this kids American then I saw the kpm and figured you live in Canada. Students here in America would never figure this stuff out in a lifetime of schooling. You're really amazing.
I am in Canada and I noticed it was in Kph too . LOL
Got to say I never thought of doing this really cool idea definitely thumbs up
No no no he never showed the rotor of the alternator, the alternator has permanent magnets, why he did not show the rotor, their is more to it
You should put regenerative braking on it by connecting a bldc motor to the chain with a voltage stabiliser circuit and battery charger that way the current draw from the bldc motor will load the chain and force it to slow down
Edit: maybe not a bldc motor but a big enough motor with a high output
Codz_526 you could just use the alternator for that, just need a controller built for it
Don't want to come off a creepy but I swear we are from the same city/town, I recognize the figure 8, lol. My buddy lived in the one off the other street. I moved to Arizona for work and I needed something to keep my boys busy and I thing we have a project now, thank you.
Awesome work! Can't wait to see the drift trike build! You have very nice quality videos and it is easy to understand what's going on. Well done😀
Awesome video, I too think it's great to see young minds at work. Keep at this and hopefully you become a better Engineer than we have today!
What I like about this video is that its got the right amount of blah , blah and video . Great idea.
Yeahh awesome video explaining all important details about re-wiring the motor windings, I like that you also mentioned the wye and delta configuration, it does make difference depending on the application.
SUBSCRIBED to your channel mate, if there are any questions about making 18650 packs just drop me a message.
*you'll need a good 5 or 6 cells in parallel minimum to deliver that current. A very common mistake is assuming is designing the pack around the "rated continuous current per cell" claimed by the 18650 manufacturers, if you get a "10A cell" and discharge at 10A continuous it will get EXTREMELY HOT, damage/cook random cells inside your pack.
Your controller will likely handle 14s or 52v nominal, you'll get a better top speed and a lot more POWAAAAAAAHHH
I love you bruno!
plz give an update on the feasibility of the electric road bike as a diy commuter
sieve5 hahaaa thaaaaanks mate!!!
Yes it's feasible converting a road bike, it's nice cause it's so light so it accelerates faster but I ALWAYS recommend people to convert MTB and use as a commuter. The reason is you're actually averaging much faster speeds and too speed too so you really need suspension and a fatter tyre. Potholes at 50kmh or faster on a skinny road bike you're lucky if you don't get pinch flat or hurt your wrist. Fat bike is AWESOME super fun but a bit overkill. Everyone likes different things, I still riding my road bike sometimes just for fun haha =]
That is actually what “sets” the phasing of a motor or alternator... how the windings are wired and in what configuration...
ElectricBike defiantly right on the li-ion batteries 6 sets parallel but if he has thr cash he can get samsung 25r 18650 batteries they are 20a continuous discharge 3 or 4 10s or 12s packs in parallel would be a great setup.
This kid is going somewhere!
Very well done, not too much talking, good video quality and good subject too. Thumbs up!
good idea used alternators are cheap
if you say so... but uh.. an alternater isn't an electric motor considering it was made for the sole purpose of GENERATING electricity.
a proper dc motor would be much much better, with a lot more torque.
Harley Me
turns out that theese alternators are quite efficient even when used as motors.

I built an electric go-kart for Burning Man. As soon as you said 'I smelled something burning', I knew it was your battery terminal, as that is exactly where mine failed too. Nothing a little duct tape and spit couldn't fix though.
Awsome video, and outstanding engineering skills and ability. Your work is inspiring and second to non! Lets hope more young men and women become as creative and talented
Oh wow! Great alternative use for an alternator! You are very smart and adorable, and I will be subscribing.
Great job son, from another old mechanic.

Left handed for the win!
Never thought of converting an old alternator to DC. Small D.C. motors used to be extremely rare.

Hey, austiwawa
what about an upgrade on this project?
you can grab a 12v brushed controller on asian wholesale sites (doesn't need to be rc-related)
use the 3s lipo on the controller
and the controller on the field coils
because if you change the voltage/tension on them
it changes the revolutions/volt ratio(known as Kv ratio)
using 12v on the rotor means max torque (idk about 4s lipo)
and if you lower that tension/voltage, the eletromagnetic rotor will be easier to run and it will go faster
@LazyH-Online I dont think just any standard 3 phase AC ESC will control just a voltage on 1 phase. You do need a brushed controller for that.
Can you somehow energize a large generator head so it could be used as a drive motor like you did with the alternator? There’s no videos on UA-cam about that topic.
There is, as usual, all lot of complaints and theory flying around about how much better everyone else could have done this, perhaps. This young guy came up with the idea for this project, made it work, and seems to be thinking about how to make it better. If there is someone in the Boo Bird section who can do it better, do it. Make a video, show what and how you did it and how simple it is, then you will have proved something. In the mean time it's just noise and smoke. Theory is what you think will happen. Fact is what happens.
Down here in Brazil, a buddy of mine went bananas when I forwarded him this video, as he has a "donor" bike that he wants to convert to electric. Alas, no money for fancy, imported motors. This how-to is a gift for third-world McGivers... Kudos big time!
Hi there! When I was stuck in a foreign country for a few months and needed a way to get around, I built one of those 2 stroke bicycle motor kits. All in all, it cost me about $350 for everything out the door including the new mountain bike. Granted, I had built 4 before that time on beach cruisers and I need a few simple tools which I brought with me, but it got me around at 28 MPH and I maybe spent $10 in gas and oil over 6 months. The engines advertise 120 MPG. I'm 185 lbs but I've seen 70+ MPG on mine which could be argued that was low geared for my application. Tell your buddy about that! Upgrades are endless and mostly bolt-on.
I thought about going hybrid with my personal beach cruiser at home by adding an electric front hub but placing a battery on a bike is not preferred. Not to mention, I want to be able to cruise at 35-40 MPH and those hubs typically only get you up to 25 MPH max so it would really only be a "hybrid assist" for takeoffs and going up hills. The electric front hub as a standalone is an easy option to get you 20-ish miles at 25 MPH (best case depending on motor/battery combo) but a good kit will surpass $350 out the door with the battery. Weigh your options.
He could probably put more juice through the coils.
Calm down, it's just a go cart.
I have decided that for many people, the crafting and distribution of retarded and ignorance-laden criticism is a hobby, as well as an art form. Hence, the ubiquitous nature and continual increase of the retardedness as these inept, useless wards of the welfare state blunder and doze their way through life trying to outdo themselves in an idiotic fashion.
There is little probability any of the commentators you refer to could operate the camera for such a video, much less complete the project therein.
Awesome project. Btw I got the keychain, thanks.

Hello good morning friend to know what type of alternator you used what features is the alternator and which brand thank you
Dove si Coperativa l'acceleratore grazie bel progetto complimenti per i tuoi video
I seriously doubt this will work for very long. Stock alternators can't use much power either. This is likely an 80 amp alternator, which is less than a kilowatt. The bearings are not designed for this kind of torque either.
Awesome work. I like to think of myself as mechanically inclined, but the information you have given is just over my head.
I didnt understand any of this but it was awesome !
Quick tip for the 18650's (i've been dismantling things with 18650s in them for a while) If you take the laptop battery and use the 18650's in those you'll have plenty of capacity but you'll need to put quite a few in parallel to get to a sustained 40-45Amp output. I find usually laptop batteries have cells ranging from 2-6amp max output but the capacity is usually between 2.0-2.7AH. If you go for power tool batteries the story is very different. A small ryobi battery will have 5 cells in series. These will only have a capacity of 1.3-1.5AH but will be able to supply 20-25Amps each!
So with the Ryobi batteries you could have a setup such as 12s 3p
And with the laptop batteries it would need to be about 12s 8p
Or just go buy the new LG cells that are 3.5AH and 10amp output.
Even 8p of recycled laptop batteries would be pushing it. You'd have hideous balance problems too. Better just use like you say, power tool batteries, hobby lipo (provides the most oomph for sure) or buy brand new 18650 cells. For range, i'd go with the latter, for drag racing, hobby lipo every time
Oh, I did just build a 21s8p with sony vtc6 cells. Spicy little battery hahaa
th3d3wd3r you can’t have balance problems with cells in parallel. They will always equalize themselves. If one is much weaker you will have a problem with the other cells having to charge the bad cell. But that’s easily fixed by just putting similar capacity cells together.
I hate LiPo personally. The majority of the Lipo i’ve owned puff within a year, and they are a bit scarier than li-ion
All well and good if he's going to run a go kart at 3.7v ~ 4.2v. He's going to need a good few cells in series to get 48v
Some Lipo is crap, others not so much. The 16Ah 6s multistars are cells of legend
Eric Fling Eric do you mind tutoring a little on that subject? I've got some experience with 18650 cells and enough around right now to learn on. I have a bike project also and plenty of cordless tools and no shortage of electronics to power. I would think enough on hand to learn a few things anyway.
Can we make use of 6 Series x Super Capacitors of 2.7 V 3000F Module connected with Battery in Parallel connection??
You are genius my friend !"
Thank you!"
I thought this was an original idea from me and been saving up for a couple years to do it thinking I was gonna make this new great invention to minimize pollution and greenhouse gases haha guess not lol.
Do it anyways
Nicely done. A word about fuses from an EE - the presence of a 40A fuse does not tell you that the current did not exceed 40A. Many 40A fuses would not fail until the current reached 60A for a long time or 80A for a brief time. Perhaps you could install an ammeter to confirm this if your batteries have a current limitation! Its good to see the fuse there as protection from a wiring short but they are not much help with overloads unless you use a lower current fuse of known failure characteristics.
People in comments whom called this video lazy.... Rather than typing all day... Stop being lazier and "make a video" :) I'd watch. Make the world less lazy and more productive.
Huge inspiration dude thumbs up!
Awesome so just do what I would do for my rc's cheers for making that clear mate :) nice n tidy build you have done well !
You did not explain how you got the relative polarities of the 3 windings correct. It does matter!
Brian Park he got lucky
Brian Park, so it seems you have a little googling to fill in the gap. Please share with us afterwards, we are the lazy ones.
It doesn't matter. If you get it wrong, the motor will spin backward. If that happens, swap any two phases and it will spin forward.
It is plain to see the logical order of the wires in their physical arrangement. No big mystery there. Even if you get one wrong it'll be easy to correct and no damage will occur from that.
Since there are three windings/phases, when one is reversed, the direction will reverse. No matter how you wire it only one coil could possibly be reversed because the other two will always be properly oriented, so it's never a problem other than rotation direction.
we want more videos like this
thank you for the like
It would be interesting to add multiple charging receptacle that accepts the style of most cordless brands, then you can just slide the battery pack into it's receptacle like a Milwaukee drill battery pack.
other creators did it, like Hacksmith's mario karts
Awesome JOb....Learn how to TIG aluminum then re-make the chassis out of Aluminum. I do like seeing young adults pushing the envelope. Use your skills to improve your situation becoming self reliant; but not to further the grip that government has upon us all. Again Great Work...."The Maker becomes what he Makes"

So if I keep making fertilizer out of cow manure and compost I will one day become shitty and dirty? I would have to say the electric motor is here and reinventing the wheel is useless. We also have lithium batteries and the technology is only getting better. The thing we should be focusing on is gearboxes that work and can be maintained easily or just replaced like batteries. Same with all other major car componets. I would love to literally exchange my battery like a propane exchange instead of sitting and waiting to charge. Tesla is going the wrong way with charging stations for the public. Gas station attendants should be trained to charge lithium batteries and there should be an exchange at the gas/energy station. (; Your Welcome Tesla... Just take a look at a good electeic blower. The technology finally caught up to a gasser. The Ego 56v vs a 50cc equivalent...as long as you have power in your batteries and you have enough to continuously charge, replace, repeat and cycle...and the things are very durable and less finicky.
The minute we have interchangable batteries, engines, and transmissions that can be taken out and replaced like a car battery is the day the car becomes as easy and cheap to own as a cell phone. This would solve many problems.
jonathan mcadams - Battery technology especially is evolving too fast for there to be meaningful interchangeability in the foreseeable future
A 100 years ago young men (mostly) were coming to an intimate understanding of the internal combustion engine. Now as IC engines fade into history like the steam engines before them, an intimate understanding of the wiring options of electric motors and their associated controllers will come to be a very valuable skill upon which future fortunes will be built.
Except the only reason electric cars appear ( I stress appear.) to be competitive with internal combustion engines is because of the massive subsidies the electric cars receive. Every time someone buys an electric car it costs you and I some money. Look at your pay stub and part of those tax deductions is funding electric cars. If internal combustion engines go by the wayside that is fine, but if it is to happen it needs to happen in a free market with people freely choosing to buy an alternative not because politicians and bureaucrats are forcing it on us. The same applies to solar and wind power. Hydroelectric is much more affordable and reliable.
Refreshing to see a young person with fabrication skills. Great job!
Was the entire battery hot, or just the terminal? Dirty or loose terminals can cause localised overheating due to their higher resistance. I've had a couple of wiring harnesses partially melt due to dirty battery terminals, and one which melted because it wasn't screwed in tight. That higher resistance might also be limiting your output power.
Another thing to consider, your motor controller states up to 45A output but doesn't mention the input current. It won't be 100% efficient and will depend a lot on your input voltage and the way the controller is designed.
Also, fuses don't always blow at exactly their rated current. There's usually at least 10% tolerance and some will easily supply 20-30% extra for a minute or so before they blow. They're good protection from short circuits but aren't very precise.
Microwave Dave i was thinking the same thing about the terminal. Not a normal failure mode.
Interesting. The one battery was warm but the terminal was burning hot. I did notice that three of my terminals were loose so this could have been the cause of what happened.
Yes it is definitely the terminal that was loose.
the battery should be fine if you were doing
Check that all of the electrical connections are tight before you apply power. The bolted connections like on your battery should be tight enough that finger pressure cannot make them rotate around the bolt. Crimped connections should be pull-tested.
This was part of the standard QC procedures at the two places I worked at that manufactured large 3-phase motor controllers.
Nice job my friend! One day a young person like yourself is going to go in his garage and throw the current laws of thermodynamics out the window and create perpetual motion.
This is one of the reasons I love UA-cam!!!
Awesome video man......very nice
Mr. Clifford Johnson is
Bruh why this dude looking like an engineering version of DanTDM
Its great to see the younger gen still playing with stuff, My kids who are 22 now, Ones into fiddling with stuff just like his dad, The other.... He struggles to match socks... This sorta stuffs not even got a place in his head. (My boys are twins and sooooo different) You got a god head in your shoulders lad, Dont waste it. (and dont make someone else rich with your ability)
Look, I'm old.
I want one of these to give to my grand kids.
Can I just buy one?
