Here is a little info, I think they are more or less one tiny amp output stage with a variable controller using mosfets. When I had my car I could hear it whine from the switching.

reason im asking is im getting into electric cars (full size). so i can get off gas man, this $hits killing my wallet.
but these controllers need to handle around 96-140 volts and 1000 amps!
... and thats for the small guys. Ive wound a few generators, but motors need timing, unless theyre slip ring designs...even then without a controller, its full torque from the beginning and that aint good.
maybe i can talk Perry into designing one...

There are motor controllers available. The one on the following site is good for 400 amps continuous.
