... Since the motor is at full voltage during the ON pulse, the motor runs at full torque during the ON pulse. A 25% duty cycle reduces the power applied to the motor close to 25%, yet the speed may not be reduced to 25% of the maximum speed. A PWM signal is at a fixed frequency. A very low PWM fr ...
