Pulse Width Modulation :Pulse Width Modulation Pulse Width Modulation (PWM) is a common technique for speed control which can overcome the problem of the poor starting performance of a n a motor.PWM controls the motor speed by driving the motor with short pulses. These pulses vary in duration to change the speed of the motor. The longer the pulses, the faster the motor turns, and vice versa.
