Category: Brushed / Brushless DC motor Driver

The DC Motor 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.


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.


  1. Control the speed of a DC motor with this controller.
  2. High efficiency, high torque, low heat generating.
  3. With reverse polarity protection, high current protection.
  4. Control voltage over-voltage protection function
  5. The overload and short circuit protecting current is 10A
  6. Working Voltage: DC 12V – DC 40V.
  7. Control Power:0.01 – 400W.
  8. Static Current:0.02 A ( Standby ).
  9. PWM Duty Cycle:10% -100%.
