Pulse Width Modulation (PWM) Motor Pull out all the stops with the PWM-ECM blower motor. Rather than using five discrete set points for fan speeds, a PWM motor works through programming. Each time the controller switches a stator winding on and off, it is called a Pulse. The length of time each pulse stays on is called the Width. By varying the pulse width, the controller varies the motor speed (or, “Modulation).
