Paul & Sabrina's cheap DIY 144v motor controller

Jack,

I understand what you are doing and why in terms of turning the contactor off and on for your field shunt portion of your motor. However, I am curious how you are feeding it the required 4 amps. I have a sepex motor and need a max of 50 amps for the field coil. I was planning on building a small PWM circuit but didn't know if you came up with something more clever.

I'm taking a simple approach for now. the shunt field is being fed from either 36v or 72v (max) by taping the traction pack. I may well end up with a pwm system but this setup will get me on the road.

quick update the contactor output hapilly drives a kilovac ev200.

Love the shirt!.

I actually work in the same building as a screen printer and I can get a good deal on multi color screen printed shirts.

If there is enough interrest, I could talk to him and see what he can do.
