 The working principle of the brushless DC motor must have the information of the rotor magnetic field position to control the on/off of the inverter power device to realize the commutation of the winding. For example, a three-phase six-state brushless motor has three rotor position sensors inside to determine six commutation points. The rotor position information of the traditional brushless DC motor is directly detected by electromechanical or electronic sensors, such as Hall sensors and photoelectric sensors.
