DC Motor Speed Control 12-40V 10A

The DC Motor Speed Control module is a PWM (pulse-width modulation) speed controller for brushed DC motors, working from 12 V to 40 V and handling up to 10 A. It switches the motor supply on and off rapidly and varies the on-time, so the motor speed changes smoothly while the motor keeps its torque at low speed. It suits fans, pumps, conveyors, drills and other DIY machines.

DC Motor Speed Control Specifications

• Input voltage: 12–40 V DC
• Maximum current: 10 A
• Control method: PWM (pulse-width modulation)
• Load: brushed DC motors; also resistive loads such as LED strips and heaters
• Output: supply voltage switched by PWM, average voltage set by the duty cycle

DC Motor Speed Control Applications

• Speed control for 12 V and 24 V DC motors and gear motors
• Fans, blowers and water pumps
• Conveyor belts, winches and small machines
• Dimming 12 V or 24 V LED strips
• Robotics and workshop projects

What's in the Box

• 1 × DC motor speed controller module

Tip: Choose a power supply that can deliver the motor's start-up current, which can be several times the running current, and keep the load below 10 A. Use thick wires for the motor and supply, and double-check the + and − terminals before switching on, because reversing the supply may damage the module.
