A dc motor controller and the brushless motor controller is equipped with the commonly used is the difference between a brush -The commutator. A controller of brushless dc motor reversing has been through graphite brush and mounted on the rotor commutator ring in contact. While by hall sensor brushless dc motor controller put back the rotor position feedback control circuit, allow them to learn the exact time of the motor controller phase commutation. Most of the brushless motor controller manufacturers production positioning controller has three hall effect sensors. As there is no brush brushless motor controller, so also does not have relevant interface, therefore more clean, less noise, in fact, no maintenance, longer life.
