Just now read this thread. Excuse me if I'm missing something.power they can put into your motors and then the motors will be fine. If the speed controller can output 100A and the motor is only rated for 50A, then just limit how much throttle that speed controller will respond to so that it never provides more than 50% power. The

Are you saying to ignore the voltage peaks and limit the average power?
Makes perfect sense to me.
A pwm is at its heart a regulator. Why build another.
My first thought before reading your post was to add capacitance to the output (if that's even practical) to limit peak voltage.
But then why bother? The motor will average the pulses just fine.
