| Abstract: | The mathematical model of the four-phase brushless DC motor was introduced in this paper. The forming reason of torque ripple of this motor was also analyzed. The overlapping commutation technique was used to inhibit torque ripple was applied in this motor. Making a system simulation using this method via matlab/simulink. The simulation results show that the method achieving good results in the four-phase brushless DC motor,and the torque ripple can be inhibited effectively by modifying the angle of overlap... |
