Frequently Asked Questions
Q: What type of motors is this brushless motor speed controller compatible with?
A: This speed governor is designed specifically for DC three-phase brushless motors. It does not require Hall sensors, making it compatible with sensorless brushless DC motors operating within DC 10–55V and up to 30A.
Q: Can this controller run a motor in both forward and reverse directions?
A: Yes. The controller features built-in two-way (forward and reverse) rotation control, allowing you to switch motor direction directly from the unit without any additional wiring or components.
Q: How is the motor speed adjusted on this controller?
A: Speed is regulated using a potentiometer that provides smooth, stepless control from 0 to 100%. The digital display shows the current speed percentage in real time for easy monitoring.
Q: What does "No Hall" mean for this speed controller?
A: "No Hall" means the controller does not rely on Hall-effect position sensors in the motor. This simplifies wiring and makes the unit compatible with a wider range of sensorless three-phase brushless DC motors.
