Frequently Asked Questions
Q: What types of motors are compatible with this DC motor speed controller?
A: This controller is specifically designed for DC brushed motors. It supports motors operating within a DC 12V–48V range and up to 70A continuous output current. It is not intended for brushless DC motors or AC motors.
Q: Can I use this motor speed controller for both forward and reverse motor operation?
A: Yes. This controller features built-in forward and reverse directional control, allowing you to switch the rotation direction of your DC brush motor as needed — making it ideal for robotics, conveyor belts, and bidirectional drive applications.
Q: How do I adjust the motor speed with this controller?
A: Speed is adjusted using a potentiometer (0–5V signal). The module includes a 10mm panel-mount hole for easy installation of an external potentiometer knob, giving you smooth, stepless speed control from 0% to 100%.
Q: Is this controller suitable for a 48V electric vehicle or e-bike build?
A: This controller supports input voltages up to 48V, making it compatible with many 48V battery systems used in DIY electric vehicles, scooters, and e-bikes with brushed DC motors. Always verify your motor's current requirements do not exceed the 70A continuous output rating.
