【Abstract】 In order to optimize an improved 18-slot/10-pole embedded six-phase PMSM with unequal-tooth structure,further reduce the motor′ s cogging torque,increase its output average torque and reduce its torque ripple,a six-phase motor torque optimization algorithm based on response surface algorithm is proposed. The pole arc coefficient,cogging width and permanent magnet thickness which have great influence on motor performance are selected for multi-objective optimization,so as to construct the data set for experimental sample. With finite element simulation analysis,the response surface model function is used to perform fitting regression. And then the motor′ s minimum cogging torque and its maximum average output torque are taken as the optimization objectives to perform response optimization,so as to obtain the optimal parameter solution. The results show that the optimization method based on the response surface algorithm can effectively reduce the cogging torque,increase the average output torque and reduce the torque ripple,which has verified the effectiveness of the response surface optimization method and the correctness of the finite element analysis.更多还原
