Abstract:Combining the response surface method(RSM) with the finite element method, a doubleside linear primary permanent magnet vernier (DSLPPMV) motor was optimized based on the optimization objectives of thrust force and iron loss. The influence of design parameters on motor thrust force and iron loss was analyzed to obtain the high sensitivity parameters. The thrust force and the iron loss for different parameters were calculated by the finite element method. The models of thrust force and iron loss were obtained by response surface method to obtain the optimal design point and the optimal dimension parameters. The model accuracy was verified by variance analysis, and the prototype was built to verify the analysis method by experimental test. The results show that the efficiency and accuracy are increased by the analysis method, and the motor performance is improved after optimization.
