Abstract:
A multi-phase brushless direct-current motor and a drive method therefor. The motor comprises a motor body and a driving module, and the driving module comprises a controller, a plurality of H-bridge unipolar inverters each of which for a respective phase, and independent phase coil windings ( 1 ) which are successively electrically connected. The method comprises: outputting pulse width-modulated sine waves with identical frequency and amplitude from the controller thereby driving respective ones of the plurality of H-bridge unipolar inverters for each phase; wherein the pulse width-modulated sine waves correspond to every two adjacent phase coil windings having a non-zero phase difference, and phase differences of the plurality of phase coil windings are identical; and outputting sine wave driving voltages or sine wave driving currents in their corresponding phases from the respective ones of the plurality of H-bridge unipolar inverters to the corresponding, electrically connected phase coil windings. The multi-phase brushless direct-current motor and the drive method therefor can realize sine-shaped voltage or current driving, thereby improving the efficiency and reducing noise.

Claim (Index 8):
A multi-phase brushless direct current motor, comprising:\n a motor body and a driving module, said driving module comprising a plurality of phase coil windings each of which has two ends; the driving module further comprising a plurality of H-bridge unipolar inverters, each of which represents each phase of the multi-phase for the motor; wherein each of the H-bridge unipolar inverters further comprises two output ends adapted to electrically connect with said two ends of a respective one of the plurality of phase coil windings, such that the plurality of phase coil windings are arranged to operate independently without a common connection point.
