DC Motor Speed Controller Kit, 5–15V, Up to 100V 7A

This DC motor speed controller kit provides adjustable speed regulation for common DC motors rated up to 100V and 7A. Utilising an NE556 timer to pulse-width modulate an IRF530 MOSFET, the circuit effectively maintains motor torque across its range. Powered by a 5V to 15V supply, it is ideal for hobbyists, makers, and electronics students building motor-driven projects.

Efficient PWM control

The kit uses an NE556 timer IC to pulse-width modulate an IRF530 MOSFET. This ensures smooth, adjustable speed control while maintaining motor torque.

Power and motor ratings

The controller circuit operates from a 5V to 15V power source. It is designed to control standard DC motors rated up to 100V with a maximum current of 7A.

Enclosure mounting

The unit is box mounted, facilitating secure placement and installation into maker projects.
