BTC-IIS Series Miniature Diaphragm Pumps (air/gas) Pulse Width Modulation (PWM) The average value of the voltage fed to the motor is controlled by turning a switch between the voltage supply and the motor on-and-off at a fast pace. The longer the switch is on compared to the off time, the higher the power supplied to the motor. The PWM switching frequency varies for different types of devices, and is selected based on how it affects the device. For example, some applications require a faster switching frequency to prevent audible noise or electrical noise. The term duty cycle describes the...
