1. a multi-phase brushless DC motor, comprises motor body and driver module thereof, and described driver module comprises phase coil winding (1), it is characterized in that, this driver module also comprises:

  • Controller, each different output controls the control pin of the H bridge single-stage inverter being electrically connected each phase respectively, its output signal is;

    the sine wave of pulse-width modulation, and drive the H bridge single-stage inverter of each phase respectively, the frequency of the sine wave signal of each pulse-width modulation is identical with amplitude;

    The H bridge single-stage inverter of each phase, the two ends of each self-corresponding phase coil winding of output correspondence electrical connection;

    Described phase coil winding is independent phase coil winding;

    There is between the sine wave of the every described pulse-width modulation that adjacent two described phase coil windings are corresponding nonzero phase difference and phase difference is identical.
