Hey im wondering if this could be used in a car audio setup my car (2019 Toyota Camry) won't take a HO alternator because of the new ONBUS LINBUS electronics build which is where the cars computer is built into the alternator housing so I can only upgrade my battery system UNLESS I can figure out how to do something like this to power my lithium then i could run any setup I want to this would be able to power a lithium Bank really well i just don't know enough to do it maybe if you made it with a different type of switch kind of like a bass knob but for the speed control im just thinking out loud and asking at the same time im literally clueless and need help to figure it out any advice would be greatly appreciated
You will need a separate voltage regulator to feed ground field to the pcm this is something that is done commonly in car audio do some research maybe outside a alternator video on RUclips lol.
What amp output is the alternator? Do you need to match it to the controller? I'm thinking of making one for a diy, electric powered go-kart. I can get a second-hand 180amp alternator for around £40.
Doesn't really matter how many amps the alternator has but what matters is how many watts it can produce, so if a alternator can produce 2000 watts, that means a 2000watt controller can run it. I'll be making another homemade motor using a faulty car alternator soon so stay tuned
@@rextech42 Ok, I've subscribed. A quick google search says - "If you want to convert amps and volts to watts, simply multiply the amps and volts." - So my theoretical 180 amp alternator x 12v = 2160 watts. Would that mean I'd need higher than a 2000 watt controller? (sorry for the stupid questions)
Answering my own question. No, I wouldn't need a higher wattage controller. Sometimes you can use a higher wattage controller than the motor, but you risk burning up the motor... Anyway, it's pointless converting an alternator when there are plenty of cheap motor and controller packages on the market that work.
Nice work! Ty! And Hey! I was holding a motor with 2 fingers, and bumped the power on for a tiny moment. And that is how i spiral ripped my finger off. shredded, spiral shattered and degloved. Looked down and there was a bone where my finger should be and finger was ripped into...Im gonna stop there!~ Yeah dont hold a SUPER high torque motor with just your hand when testing!
fundamentally a motor and generator (yes generator) are the same. A car alternator is a 3 phase motor/generator with a field winding that needs to be energized. When used as a generator the device produces 3 phase A.C. which is rectified by the diodes embedded in the device. Alternators are not especially good as motors since they require 12 V (Usually) at 1-4 amps wasting as much as 48 watts in the field winding.
@@rextech42 I appreciate your work. Other channels have demonstrated how to get a massive permanent magnet in there, but that's an extra cost, albeit a potential upgrade path.
Tengo entendido que si eliminas el regulador del alternador genera corriente alterna pero como va hacerle para conseguir 110 volts si según las revoluciones es el voltage que tendrás?
And this is one of the reasons you're getting ripped off. Diode pack is done for? Replace whole alternator. Why not having diode pack as easy to replace moduke?
There's a tiny hole for a pin to slide into, push the brushes down and slide a pin or a drill bit in to lock them in place. Once you've assembled everything, pull the pin
I'm definitely about to do this. I thought alternators were able to generate electricity through revolutionary displacement, rather than exert rotational power from electrical input. Thanks for the "input". Pun intended 😅
I know this video is a years old, but I just watched it…
Excellent, thank you!
Thank you 😊

I'm not sure if it would work but maybe someone who has more electrical knowledge might help?
Good bro 💯
This doesn't "power" anything, it's a variable speed electric motor
You will need a separate voltage regulator to feed ground field to the pcm this is something that is done commonly in car audio do some research maybe outside a alternator video on RUclips lol.
Lol totally want to do this and strap it to my bicycle to see if i can do wheelies 😆
Lol will be making an alternator powered scooter soon and see how it goes

@@AlfieMaxMiMi pointless is relative, if you have access to free junk and more time than money, there could be a very good reason!
What batteries are you using?
Just some power tool battery, lithium ion 18v 1.5a x2 connected in series to output 36v
THIS IS VERY SWEET~ VERY SWEET
Thank you, check out the brushless conversation I did on a alternator on my channel
Nice bro

Damn that's a gruesome story, thanks for sharing the info lol will take in mind
@@rextech42 TY for the nice video. Shows all the info you need to get started on the alternator to motor conversion. TY again.
No worries happy to help 😊
Just get yourself an oldschool m5 watercooled alternator 4 xtra cool points . & upgrade the bearings to timken lithium greased ones :) .
What are the two Tool Batteries for?
It's to supply the power to the brushless controller which is the main power source for the alternator
Good working bro 💯
Thank you 😊❤️
After watching several videos I have no idea wtf to do still
What part are you stuck at? I could walk you through it
@@rextech42 actually watched the video a few more times and got it thank you!
No worries
Nice bro
You will need some basic knowledge of electrical
What was the purpose of the 12volt side? Is it necessary? I plan on running 36 volts
12v to the brushes is to energize the electromagnet
It would be interesting to see what the peak power/torque output is, and also how much of a steady load it can deliver without heating issues.
I will be trying to put this on a scooter or a bike to see if it's able to move it, will be making a video soon

I'm just showing that it can be done
@@rextech42 I appreciate your work. Other channels have demonstrated how to get a massive permanent magnet in there, but that's an extra cost, albeit a potential upgrade path.
What if I shorted the rotor coils? Would it become an induction motor instead?
I wouldn't have a clue sorry
As far as I know, yes.
What size controller did you use.
500watt 36/48v
Can you also add neo magnets to armature so you don’t have to exite it with a heavy battery? Looks great though
Yes you can, have already done it, ruclips.net/video/YbUMjy9xyec/видео.html
Great Video! Would a 24V alternator be stronger / spinn faster?? If it was connected to a 24 volt battery ofcourse
No probably be slower but might have higher torque, it has to be driven by 36v and up
What voltage for speed controler and wattz
36-48v 500watt
What gauge wire did you use
What ever 20a is lol
Looks like about 12 or 14 awg (2mm2)
Tengo entendido que si eliminas el regulador del alternador genera corriente alterna pero como va hacerle para conseguir 110 volts si según las revoluciones es el voltage que tendrás?
where did the other two wires get hooked to?
Connected to the brushes, 12v for the electromagnet
can this usd to build electric three-wheeler bike medium size
Yes it's got a lot of torque but might have to gear it down if the build is heavy
what model alternator you used thanks
Not sure what model it was but you can use any 12v alternator
very cool
could you put it on a bike to make it an e bike
I'm making a electric scooter using the alternator so stay tuned for the video, will make a ebike later on
how powerful is this motor? 1kw? 10kw?
Around 1kw
Nice bro
The alternator I tried this with has 6 windings with only 3 pairs with continuity the other wires have continuity across each other
Link to controller and throttle please
ruclips.net/video/xi1Kc5IqgZc/видео.html
Please show me the process of connecting to the controller.

@rextech42 Thank you. I really needed this.
Quá tuyệt vời!
2:56 RIP to that paint job 😅
😂
And this is one of the reasons you're getting ripped off. Diode pack is done for? Replace whole alternator. Why not having diode pack as easy to replace moduke?
Ok... what happened to the 2 wire rotor leads? Care to share the speed controller spec?
It's connected to the 12v car battery just to energize the electromagnet, controller is a 500 watt 36/48v brushless
Thanks
I built one of these, and I doubled the output by connecting a spark plug to cd
Congratulations 👏
Need a motor just buy one. 12 volt alternator 150 amp 5000 watt power inverter, Solid State, no lithium batteries, Then you have a power house.😊
Let's Goooooo
Add a permanent magnet to ditch the 12v battery
Have done it to another alternator ruclips.net/video/YbUMjy9xyec/видео.html
Is the car battery enough to run it? How much time can it run?
The car battery is there just to keep the electromagnet live, main power to spin the alternator comes from the 2 drill batteries
@rextech42 nice work man. Just a quick one...how many AH must the "electromagnet" be?
@@NiteshMahabeer not sure but I've heard they take 12v and 10amps to work properly
@@rextech42 thank you very much
@@rextech42 thank you
Now put that on a mountain trike and hike...
Will be trying it out on a scooter soon and yes planning on putting it on a bike
@rextech42 make a terribly fast one wheel!
How to retract the brushes
I'm stuck😂😂
Pls send advice
There's a tiny hole for a pin to slide into, push the brushes down and slide a pin or a drill bit in to lock them in place. Once you've assembled everything, pull the pin

Powered paraglider
Why every one racing in the back ground !?
Lol i had recorded this video outside and I live right next to a busy road, also had sped up parts of the video while editing
All you did was remove the diode pack and added a power supply to the stator ????
Yup and supply power to the electromagnet
Just put a wiring diagram up ffs.
Sorry had totally forgotten to put it on here but that's why I made another video. ruclips.net/video/xi1Kc5IqgZc/видео.html
Ok gee
😂
What you laughing at?
😮
Why are electric cars not running non stop regeneration of power through motors like these ? That would be the end of charging stations ?😂
You can't create electricity by using electricity
Why are you soldering wires 🤦♂️
Are you supposed to superglue them?
@@rextech42 Crimped connectors
Will crimp them for next projects thanks
@@rextech42 ok 😒
@@rextech42 crimp over solder wtf...
An alternator is more expensive than a motor. You should do the other way around.
You don't need a new alternator for this, scrap alternator is around $20
