- Turning an alternator into a motor. I put 12V to the armature, and 55V to the stator. I used a brushless speed controller. This speed controller can be configured to different motors. I will up the voltage to 72ish volts later.
At full throttle the motor "hickups" I believe it is because of the brushes on the armatures are having issues at high RPM's

The 6 phases can be paired up in a y or delta configuration to make 3. no 2nd controller needed
sorry to be off topic but does anyone know a trick to get back into an instagram account..?
I somehow lost my password. I love any help you can give me!
@Kenneth Vivaan Instablaster :)
@Allan Uriah i really appreciate your reply. I found the site through google and I'm trying it out atm.
I see it takes a while so I will reply here later when my account password hopefully is recovered.
@Allan Uriah it did the trick and I now got access to my account again. I'm so happy:D
Thank you so much, you saved my ass !
@Kenneth Vivaan No problem =)
Did you isolate each power supply cases to make it in series? when i try to put 2 power supply in series one shuts down for some reason
Hi, nice work, if I use from 3 wires of the alternator. to have got 12V, rather than 48v, would you help me, Thank you.
12v on the armature is probably way too much. That's probably why it's getting so hot. Also if you reduce the armature voltage you'll get much higher speed out of the motor.
How i do that, Joel?
Joel, I have done that and what happens is the brushes start to bounce due to the speed. But great point, u are probably right that 12v is too much. Thank u
Just run it off 3ish volts. 👍🏼 seems to be a good armature voltage.
Great work
How about using the six phases for energy production each phase is a different amount of AC current created wired into some Romax do you break a box !
Hi.. I just want to know how do you know which 3 wires do you connect your speed controller to if my alternator has 6 wires like yours?
Check my other comment
Please make a video of how you do the continuity test after taking apart the alternator i have the same alternator i have tried alot but cant make my alternator run sometimes it tried to turn but the it would fail
Seems like a lot of extra parts to make it economical
Hi, friend I have, moter of three ways and am using for alternator, but I don't know which wire is for a switch. Please can you help.
I am working on a similar project for a Kart. The problem I am facing is low torque at start.
Can you explain if you have face similar issues?
Take a look on idle it run like hell,
What gear ratio do you have on your project?
Greetings Robert
With a sensorless motor, they have very little torge on startup. They have to spin to find the correct position of the rotor. This is why hall or sine/cosine or resolvers are used in motors. Check out "Building an Alternator Powered Bike" Austivawawa does a great job explaining everything
A similar generator pushes my car with a driver and a passenger. I like it. I also like to make interesting projects, one of which I do on my TH-cam channel
Hey mate, good to see another tinkerer'.....
I'm currently working on something very similar myself, using a 12v 150a 6 phase alternator. I thought originally that i had 6 wires in three pairs but after removing the diodes and regulator i discovered it was actually 2 groups of three (not connected) or basically 2 separate motor stator field winding's in delta (from what i could tell or atleast no center tap as seen in most connected in wye configuation) .
This really got me thinking!
Im really not even sure if there is even a practical application for this but hear me out...
Could power be generated at the same time as driving the motor. So i tested this idea and yes it can indeed, now i do understand that there are efficiency loses every time we convert energy etc and I am only a hobbyist of the trade and self taught for the most part....
For this i was only using a bare bones budget setup with a rc 60a air cooled esc running a 4s lipo along with a 12v battery and pwm controller for the rotor coil and it worked adequately for testing on the bench with no driven load , to my surprise (i expected phase interference from the generated magnetic field(s) or something) . For the first test to see if it were even possible, i had no load for the current from the rectifier diodes (which i hooked back up but only using 6 of 12 diodes) of the second stator field winding's either resulting in heat of course, actually i got a substantial amount of heat rather rapidly which caused heat to radiate to the driven stator windings and insulation melt causing a short between 2 phases that resulted in massive vibration as the phases were in an out of short, like a self oscillator. before realizing this i had put it down to phase timing due to being a sensorless setup....
i have since begun collecting parts for testing this furthar and have added a load for the generated current, upgraded to an 18fet 1500w 48-64v ebike controller running 3x 18v 5ah power tool batteries, added a second alternator motor with a belt and pulley to the driving motor with another pwm controller on its rotor coil and all phases shorted together to act as a mechanical load and several multi-meters for monitoring all the vitals. currently attempting to put hall sensors in for better low end torque and phase timing etc not to mention i have been drifting between this and my original project of using it only as a bldc motor for a vehicle of unknown type (scooter, bike, trike or go kart) until i can run some efficiency tests for that purpose. sorry for the short summary /long story but i am curious on your/or anyone's thoughts/criticisms on this and just wanted to encourage you to share more of your experiences and results and that i will be following your channel looking forward to future videos..... hope this nonsense was decipherable. cheers from South Australia Say safe

I am impressed. No telling what the rpm actually is....
I have an rpm meter now....but I'm lazy...so...we will never know.
Does anyone have any good forums/videos they'd like to attach here. I have a 240a alternator laying at home and figured this would be a good project. Figuring I should be able to put some decent power through it if I can figure out what math needs to be done ✔
I do best with detailed instructions instead of winging it. Totally down to relearn some equations.
Hey bro i asked chatgpt to improve your video title and it said to try "Unleash Hidden Power: How I Transformed an Old Alternator into a High-Speed Electric Motor!" for more clicks. Also you need your face in the thumbnail looking shocked holding an alternator with bright colors.
Lol, next video will be called the "super amazing alternator to motor video!!!!"
I wonder why the people who convert these alternators to motors can't simply explain which wires go to which places on the alternator (i.e. battery, speed controller, brushes and stator) and what they are for. That would be good information for those of us who don't have a clue as to what makes these motors do what they do - which is different from what they originally were made to do. I have watched many of these videos and though some are better than others, the people that do some of the better ones don't tell you why they do certain things with certain wires so that they become good motors that we "dummies" can convert to our use as motors. I would dearly like to convert one or more of these things for a scooter project but even if i did everything that they say to do, I don't understand what effect it has on the original equipment to change if from generating power for charging to a motor to do work. Also a good camera angle is often not present and labels on new wires (Bat +, Bat -, etc.) would help a lot.
I know you probably seen the videos but in a nutshell you basically have to rip the alternator apart and remove the diod pack. After that your alternator will either have 6 or 3 wires that went to the diod pack. If there are 3 your alternator stator is in a wye configuration. If it has 6 then it's in a Delta configuration and. You can use the alternator in a wye configuration but it will be less powerful and produce less torque. Where as a Delta configuration will be much more powerful and produce more torque. If let's say you do decide to use a wye configuration hooking the wires up to the speed controller will be a breeze because there are only 3 wires and there are only 3 wires on the speed controller. But if you go with a Delta you will need to hook the 6 wires up in a special combination. Attach 2 wires to the brush assembly as well One thing I found out is if the alternator has only 3 wires and let's say you want to use the Delta configuration you will need to find the neutral point in the stator that contains the other 3 wires
I have got the same alternator but i tried doing the same configuration just like yours but still the motor wont turn
Would it be possible to power an ac motor from a blender with a bldc controller from an rc car? I tried just taking the three wires from the blender motor and attaching it to corresponding wires on the esc but nothing happened. Would it be possible to get it working without having to do a complete rewinding?
The blender runs in 127 or 230v
I did this on a 50 horsepower boat motor and my three phase wires smoked up couldn't handle the amperage or pull for the current
Awesome, got any pics or vids?
@@ericensley2427 I do but I cannot post it on comments I believe it needs to be 3,000 Watts rated at 100 amps or higher to achieve at least six horsepower if you also Google how many watts is 6 horsepower it brings up 3000 Watts
How much volts and amps .and how much rpm ..and what about torque thanks
I think it was 48V. I never checked the RMP or torque. I didn't have a test rig to test on, I have since thrown it away
@@ericensley2427 it's look very fast and powrful
Help me l have the same project but when l connect my speed controller the alternator just gets too hot and doesn't want to run I'm using a 48vto 60v 12mps battery and 1500 speed controller what could be the problem
Put like 5-10v on that armature
could you run a 2nd alternator with a belt onto the first and than use the 2nd's output current/vol to power the first? Maybe it will be selfrunning.. free energy??
Alternators are about 50% efficient. There is no such thing as "free energy" Anybody offering it or saying they have it is a snake oil salesman
السلام عليكم ورحمة وبركاته أنا مصر من طنطا محتاج قطعه ارجوك كيف احصل عليه لنى مش عارف اعمل زيها ولم يوجد في مصر
Hola buena tarde amigo una pregunta alternador cual carro porfavor sy venezuela me avisa gracias amigo
2001 f150 V8
Eric Ensley hola amigo digame
It's not 6 phases, those are just the other ends of the 3 leads your using.
You shouldnt run these on low speed. there is not cooling enough. At normal engine idle the alternator spins at around 3000 rpm. So keep alternator between 3-15000 rpm is the best.
Hall sensor connection
Controller senser or senser less
Sensorless. only did bench testing, never put a load on it. Probably low start torque.
beeee this is not the whey ... brother. wiering rebuilding_ than meibe. rotor whith neodin nagnets_ than meibe. and calculating to 48V than meibe.
hahaha
