Brushless DC motor comprises a permanent magnet rotor, multi-pole stator winding, position sensors and other components. Position sensing by use of the motor rotor position changes along a certain order of the stator winding current commutation (i.e., position of the motor rotor poles relative to the stator quote detection winding and the position sensor generates a position signal determined by the signal After conversion circuit processes to control power switching circuits, according to a certain logic were winding current switching). The operating voltage of the stator winding electronic switching circuit by a position sensor provides an output control. 3. Press the start and operation mode can be divided into: single-phase capacitor start asynchronous motor, capacitor run single phase induction motor, capacitor start single-phase induction motor operation phase and single-phase asynchronous motors.
