Can't wait to get the lem setup. That should make a difference. So far the igbts seem to be behaving fine. Granted its not really stressing them just running an unloaded motor. I think i'm gonna go with one 800amp device as the switch and one as the freewheel. See how it behaves. Should the lem be on the battery or motor side?
Its very impressive the degree of control available. I wonder could we design in a means to monitor motor rpm? I'm looking at making a simple circuit with a 12f pic to kill the pwm if the motor hits a certain rpm.
