10A PWM DC Motor Speed Regulator

PWM Motor DC Speed Controller allows controlling direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 10%-100%. The motor speed controller can provide a continuous current of 8A to your DC motor or other DC load. The circuit also includes a 10A fuse, with the reverse connection of power supply and control voltage over-voltage protection function.


DC motor governor input is DC, can not directly connect to the AC (for example home 220V AC), otherwise, it will burn!

DC power supply positive and negative terminals do not reverse, otherwise, the governor may be damaged.

The motor can be positive or negative when the direction of operation and expectations do not match, you can adjust the line order to change the direction.

Adjust the potentiometer knob to change the governor output duty cycle, the motor speed changes.

This can NOT be used to the BRUSHLESS motor. The controller is NOT reverse-polarity protected and will be damaged if it connects the supply voltage with the wrong polarity.


  • Control the speed of a DC motor with this controller.
  • High efficiency, high torque, low heat generating.
