- In this video I successfully convert a car alternator into a brushless motor. I do this by removing the field coil electromagnet from the rotor and replacing it with a permanent magnet. Old Rusty is now on version 4! The alternator is from a 1998 Ford F-150.
Battery is 18.2Ah made using Sony VTC5 cells (13S7P).

Hello good night friend, I liked your experiment very good, it's a pity that here in my country we are very late and everything here is very expensive but I will try to gradually get the necessary parts to assemble an electric bike like yours congratulations
You got eBay ?
I rebuilt alternators, starters & generator's for 16 years . If I knew you was going to do this I could have saved you a hole lot of time by getting a "delco 25si alternator" a brushless alternator for semi's & heavy equipment . The down side is the size mainly the length about 2x & larger diameter , the plus they use less power to excite the rotor should run more efficiently ?. I would love to see how well a 25si performs .
That hand gag got me... I can't believe it. Good work
Really enjoying your DIY electric build series, would love to see a part 3 with added field weakening to take advantage of the brushless upgrade! Keep up the good work mate.
Immediately clicked like after your magnet safety demo :) I need to build one of these this year.
I am sooooo happy that you made this project fully brushless and sensored!
Now i would love to see you revisit the go-kart using this alternator, i wonder how will be the difference in a 4 wheel vehicle
I definitely wanna see that
A lightweight alternator kart would be a fun idea! Thanks Foxxy
@@austiwawa - Probably work better on a cart. Isn't the balance of the bike effected by the weight of the alternator attached to the side like that?
@@austiwawa how did you modify the back wheel ? you've done things to it from when you got front motor.
Thank you for your great works. Please add step by step processes.
Awesome project! I would love to see these conversions produced to power all kinds of electric vehicles 🚗 😮😅❤🎉I l love the idea of combining an American alternator with a controller made by ASI in Canada! Then you are using primarily North American made parts !😮❤
Another great video. Perfectly produced in all of its detail.
This series has filled in so many gaps in my knowledge about how 3 phase electric motors and generators work.
Amazing work as always, Austin!! 🔥👍
So awesome that you were able to eliminate the second battery and the brush. Cuts down on battery costs for someone like myself considering this project. Have you seen Mr Electrons BLDC controller? I think that's the direction I want to take my build for simplicity sake
Well done! This is a great use for a junkyard alternator. From an engineering standpoint, I always try to go simpler, so I love your idea of converting to Brushless DC. Good a/v, very good narration and explanation. Great channel!
Great job, also the video presentation, narration and editing was excellent.
Your engineering skills are amazing
This was realy cool love the conversion of the alternator
Very cool that you know so much about the electric tech! That said you didn't get much range out of the rig! My $1500 RadRover ebike gets at least 20 to 30 miles from the 48 volt setup... with some pedaling assistance of course.
Nice job, you inspired me to build an old rusty of my own.
Thanks.
Old Rusty's unite!
Follow your dreams young man. When someone tells you that you can't do something or it won't work, PROVE THEM WRONG 👍
This video was fantastic, super informative and entertaining. Subscribed
Awesome video!!!
Quite the inspiration to DIY'ers out there!!!
Great vid! I'm sure that alternator can generate some serious electricity with such a powerful permanent magnet now. I'd be curious to see its output measured as a generator!
Awesome content, as usual man! I did this same mod about a year ago and honestly, I couldn't find any info on it and was blown away more ppl hadn't considered doing the same! I think that a lot of ppl don't quite realize how the rotor of an alternator actually works... it is kinda intimidating seeing those big triangular teeth inside, but still. I was impressed w how it worked so it's awesome you're showing us how here!
Cheers mate!

Thank you!
So glad to see you are continuing this project. I was very looking forward to it from the teaser you provided at the end of the last one. Nothing says sadness like having a half full battery and your field batteries die. I think if I where the kind of Maker you are, I'd have made a way to recharge the field batteries off the main pack when in a pinch. But that's just me desk chair coaching. I want to make one or a pair of these for a cart project I have been scheming on for ages. Thanks for proving that these Alternator conversions can be torque monsters.
the idea is sound and it will work.... there are several things in this video that they have not even addressed... like the AC voltage alone will do nothing, hence the power brick that converts the 120 to 24 volts... but in the end, this works flawlessly... the generators are easy to find and the motors as well... just have to do some searching.... I am putting a video together as well as a live public display of it working by the middle of July... just wanting to make sure the parts will be available for everyone.... no I am not affiliated with this channel...lol.... too many hidden parts in this video....
This is really cool and well made! Thanks for making it and sharing!
I watched your last video with some significant envy, and then you drop another with another fair step in the evolution of Rusty. Great stuff. Keep it up!
Oh, and can you provide a source for the magnet you bought?
Inspired by your video, I'm going to give this a try. I am looking for reliable low-cost motors to build some sprint kid karts, and this looks like it should fit the bill both power and price wise. Plus it's crazy "green" to boot. Grabbing the alternator of a donor vehicle tomorrow.
Pretty darn cool , I would not be able to make that work . Thumbs UP to you !
Mmm
70 Kph on that bike - Absolutely insane :D
43.496 MPH is amazing!
The prototype should could use some useful Upgrades in the suspension area..
You are absolutely awesome and I appreciate your professionalism and knowledge of this subject and in the very near future you are going to be very valuable to the electric ⚡️ vehicle industry.
You are one smart kid!!! You will further electric cars and bikes and only God knows what other wonderful inventions you will bring to us!!!
This is some genius stuff, good on you!
Cool DIY video & nice use of time-lapse & nice clear explanations ; Good job!
You must be in Canada, given accent, English, no traffic & snow on the landscape near the roads // lol .. metric kw / kmph / km distance / units :)
Around 1ah per km // it seems
Keep on Trucking...love your vid!
Hey, that looks like Jordan. Awesome video once again!
I loved riding my bike through that area! Great video 👍🏼
Dude your video skills are excellent. Hands down one of the best quality channels out there
Thanks! You guys are the best sponsor out there!
@@austiwawa This is something that i have to agree 1000%!
@@austiwawa Also, it would be awesome to see you putting this alternator back into the go-kart to test it, comparing the first version from the old video (sensorless, LiPo rotor feed, and chinese controller), to now in 2021 (hall sensors, PM rotor, and Kelly Controller)
Word!
@@austiwawa Hey dude absolutely clever conversion of the alternator.My question is "can you rig up some type of generator to have the bike self sustain run?"with peddle asist.Mabey a 24v moter converted to a generator to run the alternator? THAT WOULD BE OSOME!!!!!
Great stuff. I like seeing young people that can teach me things. I tried to figure out where you are but failed. Probably Ontario, maybe Langley.
I figure he's around Grimsby or thereabouts, near the escarpment. The fruit trees are a dead giveaway. Violating the HTA exceeding 32kph on an electric! But I'm not complaining. Better than putting out a few grand for an EMMO.
Now we need to see a twin alternator bike, with 2pacs.
I think I saw you flip a speed limit sign!!. lol. Cool Project.
I also started a project like this, first I built amazingdiyprojects's 1phase bldc, but that didn't work well, so I used a washing mashine motor instead, but the 3d printed gears broke, and the voltage was too low. You gave me back my motivation to think about finishing it. While working on it, I constantly thought about an alternator conversion like yours, but did not find any source on that a year ago, so did not make that. Yours is a pretty elegant solution, well executed, keep up the good work!
To be honest there are good alternator conversion videos out there
@@foxxyytofficial I wanted to use permanent magnet, but I did not like the "grind down a bit, and put a magnet on every spike with superglue" technic. And I didn't have an alternator.
@@kevegonczi2835 i wouldn't recommend that idea for you, i prefer conversions like the channel "Chris workshop" did, that is a better permanent magnet solution
Well done man, continue your doing
👍👍👍
Killer job bud!
I will try to do it! Thanks for the great video!
Very nice. Good job!!
I can’t believe how well “Old Rusty” took that hill. I’ve ridden it with my e-bike and she struggles even while I pedal. The torque on that motor is serious! You should see you can measure it for comparisons! Great vid Austiwawa!
I wonder how it would compare with motor you can buy from Amazon or ebay for a few hundred dollars. There is a pain in the ass factor to this conversion.
@@ineffable1129 the idea is not to never buy standard motors, but to show that you can use alternators
Basically made an electric moped with an alternator and a few batteries, I'm impressed!
(especially with the uphill performance)
It's really cool to convert an old alternator into an e-bike kit. The top speed is impressive, but the efficiency is relatively bad. I generally get around 7wh/km, but the top speed of my system is 50kph and I always have a switch that limits the speed to 35.
I was pretty confused when you put in what looked like a single permanent ring magnet, but there's actually 6 magnets in there.
Hey it works with a bridge as well, I am thinking of putting a step up converter to charge my battery, while braking. And I put butter under a magnet, so it did not crash hard.
you did some great work -
scientific method, used to a
plausible degree, finds trial & error
to help make concise end results..
expanded continuations have improved
your personal presentation style,
which will always be intransigently
applicable, can easily come to meet
higher achievement..
thanks for the experiments, we'll
check out your examples and
see you in later episodes.!
~WarriorPoet~
Nice job, no doubt the permanent magnet brushless set up would be a little more efficient too increasing your rage slightly.
Maybe put the motor system on a 6 or 10 speed so you get the extra gearing and a better top end? Also would help going up hills by down shifting?
That's really good for a car alternator. fun for the hole family.
Old rusty v4 looking so flyyyyy 🚲💨 happy your fingers stayed safe and amazing video once again mr. wawa 💗
You are pretty talanted !
Funtastic ebike - been following your builds and I'm so impressed.
Could you try the range test on a slightly warmer day and keep your speed under 35kmh as wind resistance at speeds above that
result in a massive increase in power needs to maintain those speeds.
So impressive going up those hills though.
Well done and thanks for your video's.
Thank yoU!
Great videos. I bet you'd have better range in the summer when you don't have the cold acting against the batteries.
Insulation of some sort around would help with that, be cool to see if there's any difference between the two.
Nice work....👍
Nice video, there is no limit.
The dude is somewhere in Canada. Awesome job.
Whoa! You used quite the magnet. Noice!
I don't understand any of the scientific stuff you do but it's very Kool😂
That's cool I've been thinking of doing the same to one of my bike's great video
thank you for your great effort and sharing awsome work💗💕🌈
Well done . Thank you.
Maybe you could build a backpack that holds another big set of batteries? That way you could look like there's no batteries lol just a fun thought. Thanks for you videos! I love watching other inventors, if that's what we are called lol
Great Ideal. Please do away with rag joint wheel. Use Hub adapter. Mine crushed spokes .
Cool and amazing. I have an old alternator off a 79 chevy pick up. Guess what I'm fixin to make.
I seriously hope this video gets more views
6,503 at the time of my original comment
Nice ! and now I've seen a couple of ur vids. I say > Yes you are absolutely capable of making your own motor <
also for a comparison my Go Ped with a 2 stroke gets well over 200mpg. On a 1 liter tank I can travel roughly 30-50 miles. Top speed is somewhere between 20-30mph. It varies by how heavy the rider is & also road terrain. You can ride for hours without a care.. except, DON'T fall ! U don't want to eat it on a scooter , lol
You should try mounting a 2 stroke to old rusty ... or maybe old rusty's brother ...
That magnet is one lump eddys will gather as heat overtime in there now rather than the segmented copper of old, good effort though nice and simple mod.
So what do you think of doing a 200 amp alternator and a very powerful controller and use a dc speed controller on the electromagnet to reduce the field to 1.5-2v for cruising. 12v is a bit overkill as I think they saturate around 5-6v.
Brilliant stuff.
Thanks!
Great video keep up the good work
Thanks!
10.5 miles not too bad would be fine for most in-town use. I would add a second back up battery just in case
Im two
It will do double the problem is the hills and temperature.
This young man is far more intelligent than people giving him advice in the comments.
So interesting; thanks for sharing!
Yeah, the fake hand fooled me too.
I have had this idea for a long time and have been looking to see if anyone did it already. I have some alternators to take apart now.
Nice thing to mention, by swapping the rotor coil to a permanent magnet, you saved a lot of energy witch would be used to create the magnetic field.
this allows lower current drain from the batteries, less heat generation, henceforth gain more mileage with the same battery.
Very nice! I'm currently in the progress building a 3d printed rotor made of magnets to do a full brushless conversion of one small alternator I had laying around.
Oh hell yeah! I am happy to see you here!
@@foxxyytofficial Thanks! 😄
Sounds very cool! Will defs check that out!
@enginneering
Where can I see your rotor project?
@@Slic-Rock in his YT channel
Excellent built and modifications, I couldn't see where is the polarity N or S of the permanent magnet, when installed on the shaft. I would like to know, thank you!
Nice content Sir
Excellent sir
Pretty interesting project, dude! Really nice! 😃
And worked great!
Stay safe there with your family! 🖖😊
Thanks MC!
As others have pointed out, cool temps hurt your range. Try again this summer!
Awesome achievement.
АПАЗДАВАЕШЬ ты,брателло, такие технологии по переделке генераторов электромагнитного возбуждения на возбуждения постоянными магнитами ЛЕТ 15 НАЗАД ИЗВЕСТНЫ БЫЛИ.......В СОВЕТСКИЕ времена в СССР ХВАТАЛО ТАКИХ умельцев;-тогда аккумуляторов не хватало на всех,да и дороги они были и не долговечные; вот люди включали мозги и создавали такие электро-шедевры, что чертежи таких девайсов ложились на столы Советских Конструкторов,и промышленность выпускала уже торговые марки электро товаров.....
Fantastic!!! I am, childlike, wondering. If you have a standard e-bike, is there a way to have the battery charged by the pedaling motion? Instead of charging the battery from the grid.
Please post a link to the magnet supplier. Awesome work!
You can find rare earth (neodymium ) magnets many places on the net. Just do a search. The larger magnets can really bite you.
Very cool video
next step, different wheel bearings and trying types of grease XD
the bike prolly has those crappy un sealed bearing in the hub. he should def ungrade the wheel hubs with sealed bearings. could also take the freewheel off on the rear wheel to free up more friction
nice job
It´s still working? What is the voltage it can suport and about how much time it can suport pls?
damn, you really turned that motor into gold, brushless, it might not be efficient, but will probably be trouble-free for quite some time😎
I think you have power to spare. Try a larger sprocket on your alternator, maybe get it up to 90km/h. A couple etra teeth should do it. Awesome job on the bike, you inspired me to build my own. Love the detail you go into, especially the diagrams, saves me the trouble of the research. ✌️😎
Bad advice on a rusty old bike. Imagine doing 90kph when the front wheel explodes. Not pretty. Also in violation of the HTA.
@@loginregional who gives a fuck about the hta the tire exploding though definitely sketchy
@@Agilepickleunite Obviously you don't realize that not obeying the HIGHWAY TRAFFIC ACT creates a hazard. You are pretty ignorant. Stay off the road.
Hello sir!
I appreciate your work,
I used to have the same idea in past but has strong doubts and now you helped me,
I want build one but my only struggle is the esc
I don't want to buy a limited power ebike controller (esc) instead I wanna go for a RC (flying objects) 60 amps esc
Idk if it works and don't who to ask
Great job ...
Looks fast.
Hi.
Congratulations man!
Good work!
Please share the link to buy the permanent magnetics.
In Brazil we dont have this type.
Please tell me if you have no problem with loss of magnetization due to high temperature?
Thanks.
Where did you get the magnet? I'm not sure where to look lol. Also what would be the affect of a thicker magnet vs a thinner one?
Great video mate. Any links to the magnet, cheers Graham
Definitely saving on battery not powering the Rotor.
Just wondering what difference segmented magnets in Rotor would do instead of the Wedged shape metal as I'm sure you'd have even more power and even less battery usage.
Sure you could do a follow up video on that ?
"Chris workshop" (without the quotes) did a video on a non-claw pole alternator rotor 3d printed
