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
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
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.
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
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!
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!

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 !😮❤
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.
@@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)
@@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!!!!!
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?
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!
I love that you use the metric system! So we in the rest of the world can understand... You didn't go further because of the cold Temperature. It safe to add at least 25% to your range numbers in the summer.
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.
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....
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!
@@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
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.
Nice build.. mine is in process.. 2 Littles questions: is it wrong to let the 12v in the rotor as immobilized, like at a red light? Do you turn it off? And how long the 12v battery last and how big is it?. Tanks for sharing.
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
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.
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.
Stupid question - what would happen if you kept the field windings, but instead of using a battery, just shorted the brushes to each other? This is a pretty awesome project. You've got me wanting to find an old alternator to see what I can do.
Shorting the brushes together would still spin when applying voltage with the BLDC controller, but the magnetic field would be too weak for usable torque
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.
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.
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.
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.....
hello I'm trying to build an ebike using your video. if I'm using a 10 speed gear system do I still need a controller? also if I use an altentor can I still use a drill battery, or should I just use a torque drill as a motor?
Dud you have no idea what you've started. You have just created a bunch of Mad scientists. Now that you've shown us; we can pull alternators out of cars in the junkyard for way cheaper than we can buy a comparable electric motor anywhere. You are truly a national treasure for us all. And trust me; just what you did by removing the material from the two sides of the center armature to add the permanent magnet simplified things a lot. And correct me if I'm wrong, but; you don't get regen until you add the permanent magnet "Right"? Thumbs up! Like and subscribe, vary cool!
Do you think the change in speed and range to almost double the figures between the Gokart build from 5 years ago and this one, was it the weight and amount of friction generated from the four gokart wheels or something else?
Probably multiple things: Changing battery from lead to lithium (less weight and more poeer available) Adding a better/more powerful controller and the hall sensors And changing the electromagnetic rotor for a permanent magnet one
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 ...
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 ?
Can you use the electromagnetic rotor as a sort of variable field motor by increasing or decreasing the field voltage so that you choose high torque or high rpm
Would get you more range and better acceleration. If you use the "buck converter" he mentioned, it would be a simpler control point while still removing the second battery.
@@jameswyatt1304 about better acceleration i don't know, since it already was at full current with the 3S LiPo But range would only be better if he could adjust on the fly, and that is dangerous
I dont know that much about motors but do you think there’s a way to install a second alternator to charge the batteries? I know there’s no propetual motion. Just a question.
Unfortunately no, because even if he do the same modifications to get better efficiency, the result would be worse than if he did configured Regen Mode (his controller can do it) to get some of the braking energy back and earn a few extra miles/kms
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.
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! - Jesse
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. ✌️😎
I have a question. At 03:50 you start pushing one of the red parts into the axle of the rotor using the puller. I don't understand how are you using the puller to push in the manner that you do. Can you explain? It seems to me it shouldnt push at all from the geometry you are using. Thank you!
@Barstools And Powertools Ahhhh. So the top poll piece is highly atracted to the magnet and he is using the extractor for stability lowering it step by step thru the extractor screw. It makes sense now. Thank you!
Have you check the Super Soco motorcycle (the cheaper one) I think that bike makes around 100 km range but it costs like 5k usd or more, how much did you spend on your set up? To calculate how much you will you need in batteries to go near that range of 100 km range?
I have a question might sounds stupid but Neodym Magnet are very expensive but have an high field strength. Could a ferrite magnet also work. What field strength do you see on a conventional alternator rotor with an hall probe. Than we would have a measure to compare. Greetings Bob Great Video excellent graphics. Thank you

What's its max peak power? And max continuous power? How much energy did you save with the permanent magnet setup?
How much (in percentage) were the electricity savings from cutting out the field winding current?
Keep on Trucking...love your vid!
I don't understand any of the scientific stuff you do but it's very Kool😂
Great Ideal. Please do away with rag joint wheel. Use Hub adapter. Mine crushed spokes .
The dude is somewhere in Canada. Awesome job.
Have you check the Super Soco motorcycle (the cheaper one) I think that bike makes around 100 km range but it costs like 5k usd or more, how much did you spend on your set up? To calculate how much you will you need in batteries to go near that range of 100 km range?
Very nice. Good job!!
Can you share a link for the magnet, I like what you did
How much torque is it outputting
Appreciate your project and could you pls show connection diagramme of three wires from stator to battery? Thanks
These diagrams are easy to find. They're the same for all 3 phase bldc motors.
Can it go 6km up the hill on those batteries . Thanks
Well done man, continue your doing
👍👍👍
i can see your tires are low, always check psi on tires! you will get a better top speed!
better top speed and better range too
I recognize those roads, you must live in the sleepy little paradise called Jordan.
Hi guy lovey have you done any tests to determine hp and Torque this is going to be set. Controllers current mainly
How many kms can it go ?
@@arthurquinn7515 he said in the video
Well done . Thank you.
Now try a LIFPo battery👍
I have a question might sounds stupid but Neodym Magnet are very expensive but have an high field strength. Could a ferrite magnet also work. What field strength do you see on a conventional alternator rotor with an hall probe.
Than we would have a measure to compare.
Greetings Bob
Great Video excellent graphics.
Thank you
