Important Notes
- Input must be DC only — do not connect to 220V AC mains power.
- Input voltage must match the rated voltage of your motor (DC 5V–36V).
- Motor wires A, B, C have no sequence distinction — no need to worry about phase order.
- Product styling (new or old type) may be sent randomly; both are functionally equivalent.
Made in Mainland China.

Frequently Asked Questions
Q: What types of motors is this brushless motor speed controller compatible with?
A: This controller is specifically designed for 3-phase brushless DC motors. It is not suitable for brushed motors or AC motors. Ensure your motor operates within the DC 5V–36V voltage range for safe and optimal performance.
Q: Can I use this controller to reverse my motor's direction?
A: Yes! This module supports both clockwise (CW) and counter-clockwise (CCW) rotation, making it easy to reverse your motor's direction via the integrated reversible switch — ideal for robotics, conveyors, and DIY automation projects.
Q: How do I adjust the motor speed with this controller?
A: Speed is adjusted using the built-in 270° linear potentiometer, allowing smooth and precise control from 0% to 100% of the motor's speed. Simply turn the knob to dial in your desired speed — no additional hardware required.
Q: Is overcurrent protection included in this speed controller?
A: Yes. The controller features a 15A protective current limit that helps safeguard both the controller module and your motor from overcurrent conditions during operation.
