| Abstract: | The working principle of the six-phase BLDC motor was analyzed,and its state equation was deduced.The simulation and experiment research on the key factors-counter EMF and current waveform,which were produced by the torque,were performed with state variable,and the harmonic torque of six-phase BLDC motor was analyzed and deduced.At last the conclusion was obtained that the sine harmonic torque can be decreased or removed by reducing the current lagging angle. |
