How It Works
The module controls the speed of a brushed DC motor using Pulse Width Modulation (PWM). Instead of reducing the supply voltage directly, it rapidly switches the motor power on and off at a high frequency. Adjusting the rotary knob changes the duty cycle of the PWM signal, increasing or decreasing the average power delivered to the motor. This method provides smooth speed control with better efficiency and lower heat generation than traditional voltage regulation.
