It does not require Hall sensors, making it compatible with sensorless brushless DC motors operating within DC 10–55V and up to 30A.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this controller run a motor in both forward and reverse directions?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How is the motor speed adjusted on this controller?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does \"No Hall\" mean for this speed controller?\u003c\/h4\u003e\n\u003cp\u003eA: \"No Hall\" means the controller does not rely on Hall-effect position sensors in the motor.
