Dc motors: relationship between PWM frequency and Torque
Without the alternator working, 50% PWM would get rather close to 50% torque if inductance is not too high, and the PWM frequency is chosen right. … But the 50% time that PWM is off, you get reversed torque, and that's what causes your observation about 50% PWM not giving 50% torque. …
