DC Motor Speed Controller

  • Working Voltage: DC 12V – DC 40V
  • Control Power: 0.01 – 400W
  • Static Current: 0.02 A ( Standby )
  • PWM Duty Cycle: 10% -100%
  • PWM Frequency: 13 kHz
  • Control the speed of a DC motor with this controller

High efficiency, high torque, low heat generating
With reverse polarity protection, high current protection

· The 10A fuse with the reverse connection of power supply and control voltage over-voltage protection function
can adjust the speed by the external 0-5V signal

NOTE: 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. Double-check all connections before applying power and always turn off the power supply before making any wiring changes.


  • First, connect the dc motor negative positive to the knob connection point.
  • Fix a gear wheel on the motor and fix it with the screwdriver.
  • Now connect the 12v.1amp adapter for power supply of controller and switch on the power and turn the knob you will see the speed variation on the wheel.
  • You can check the voltage rating using a multimeter. Connect the Positive wire of multimeter to the red wire of motor and similarly connect the black wire of Multimeter to the DC motor black wire.

Schematic –


Rotate the potentiometer and you can control the speed of rotation motor.
