PWM DC Motor Speed Controller 9–60V 20A | Motor Driver
PWM DC Motor Speed Controller — 9V to 60V, 20A Max
Take precise command of any DC motor with this compact, high-performance Pulse Width Modulation (PWM) Motor Speed Controller. Engineered for makers, engineers, and hobbyists alike, it delivers smooth, stepless speed adjustment across a wide 9V–60V input range — all in a rugged aluminum-alloy housing small enough to fit almost anywhere.
Key Features
- Wide Voltage Range: Operates on DC 9V–60V (compatible with 12V, 24V, 36V, 48V, and 60V systems), making it versatile for a broad range of motors and power supplies.
- Precise PWM Speed Control: A 25 kHz PWM signal combined with a simple potentiometer dial gives you 0–100% stepless speed adjustment for silky-smooth motor control.
- Forward & Reverse Operation: Supports full bidirectional control — simply switch the direction signal to reverse motor rotation without rewiring.
- Built-In Protection: Overcurrent, overheating, and overvoltage protection circuits safeguard both your motor and the controller, extending the life of your equipment.
- Compact Aluminum-Alloy Body: The 92 × 52 × 36 mm form factor and lightweight 135 g build make installation in tight enclosures or machinery effortless.

Frequently Asked Questions
Q: What types of DC motors is this PWM speed controller compatible with?
A: This PWM DC motor speed controller is compatible with most brushed DC motors operating within the 9V–60V range, including motors commonly found in electric vehicles, conveyor systems, fans, pumps, robotics, and DIY automation projects. It is not designed for brushless (BLDC) motors.
Q: Can I use this controller to run a 12V or 24V motor?
A: Yes. The wide input voltage range of DC 9V to 60V means it works seamlessly with 12V, 24V, 36V, and 48V DC motors, making it one of the most flexible PWM controllers available for multi-voltage setups.
Q: How does the forward and reverse function work?
A: The controller includes a direction-control input. By toggling the direction signal (e.g., via a switch connected to the direction terminals), you can reverse the motor's rotation without physically swapping the motor wires — ideal for applications requiring bidirectional movement such as conveyor belts or automated gates.
Q: What happens if the motor draws too much current?
A: The built-in overcurrent protection circuit automatically limits or cuts power if the current exceeds safe operating thresholds, protecting both the controller and the connected motor from damage. The controller also features overheating and overvoltage protection for added reliability.
