12V is way too high for the rotor brush slip rings. You need to use 5V and less. I believe 5 V is start up, and the rotor spins faster as you turn the voltage down. I believe this is where you put the servo tester- throttle, between the + from the 5V source and one brush connection.
Have you looked at Youtube for Altermotor OR Alternator conversion? There are several videos. The LINK I posted, takes you to a long thread of Alternator conversion information.
When you get this working, post in this thread how you succeeded, so others will understand.

Skalabala said:I would say the problem is in the controller. When it starts to inject the starting currant you should hear a wining noise.
I have played with a few motors using a RC controller and I found that some of the motors must be manually spun really fast before the controller can take over to make it spin.
Harold in CR said:I have no idea what that connection set up is. Does yours work yet ?
This one is called Star, Why or just Y connection scheme.kejanostra said:I maybe found the real " delta with coupling " of this alternator conversion!
Because by looking at the video of this guy, I put on stop the vidéo for see how he connects these 6 wires,
and they are also wire double as me.
I have make another plan, then tell me if you see the same thing as me I. 8)
Look good:

My plan:
Skalabala said:I really can not see why you are struggling so much
Find the coil phases by testing with ohm setting on the multimeter.
Test two ends at a time until you find three pairs that are identical resistance.
PS: what is your home language?

What problem with my language? I am Corsica!![]()
And I make the effort to speak in English, I am not English origin sir.
And, I found these 3 phases! " THEY DO NOT WORK! ".
Harold in CR said:The cheap Chinese controllers will burn up if you try to start the rotation of the rotor with a full start. This way, you are trying to make rotation by NON sensored means. I don't think that will work.
In the videos you posted, there were 2 servo testers, I believe. It MAY be that the guy has installed 2 Hall effect sensors, so the controller knows where the rotor is positioned, N-S, so it can induce power to get rotation.
I am simply guessing on this, but, I seem to remember something like this from the RC group, link I sent you. There are 45 or more pages to read in that link.
Skalabala said:If you buy a chinese controller then you need to buy one of those 200A ones.

12V supply (3V rotor supply)
I'm currently using HK 150 car brushless ESC running in sensorless mode, and a brushed ESC for the rotor supply, both ESC controlled by AVR8535 processor, which gets an input from joystick functioning as throttle, and a slider potensiometer as gear selector. For a very powerfull start up, I'm powering up the rotor up to 7V, and decreasing it to 3V
Once you power-up the rotor through the slip-ring, it become a normal brushless in-runner motor, so you could spin it off using normal RC brushless ESC, just make sure that you use the large one as the current for start up is quite big. I always used at least 100Amps rated ESC
I did not have a brushless controller, so, I never did get my altermotor running, YET. I still plan on it, with my 24V 150A Alternator.![]()
