The regen current is monitored by the current sensor. It can do -900 to 900amp. I think the intrinsic diode would be fine? The hardware overcurrent circuit would have to be modified a bit so as not to allow too much negative current either. Hey, you could do a PI loop to command a certain regen current I think. Maybe the gas pedal could be modified to allow for forward and backward current.
Fran was telling me that SEPEX motors and controllers can regen just about as well as A/C motors and controllers.
