its cos the controller chops them both up (pwm) to produce about the same result (say 18kw) for the motor and fets in both cases.
and i agree it seems like the low resistance and inductance is hard on the controller, the current rise time is too short for
it to regulate smoothly, be worth seeing if kelly can help?
