Could someone tell me what the effect of controlling a PM motor with a PWM controller has on torque. For instance, if the controller is at 50% duty and the motor is stalled should it produce 50% of the torque it would produce if at 100% duty?
Reason I ask is I'm writing a gearing calculator for an electric endurance racer and the real world data we're using to verify the simulator's output tends to indicate much better performance than I would have expected for the PWM controlled races compared to races where a simple relay was used for the motor.
