PWM means Pulse Width Modulation. It is a way of controlling power by turning a signal on and off very quickly. By changing how long the signal stays on, PWM can make a device seem stronger or weaker.

For example, a fan may use PWM to run slowly or quickly. An LED light may use PWM to dim without changing the color. Many machines and electronic devices use it behind the scenes.
