Abstract :
This paper introduces an optimal design process enable the optimized spoke-type interior permanent magnet synchronous motor (IPMSM) to effectively reduce the cogging torque by considering the torque and efficiency by maximum torque control. In the optimal design process, response surface method (RSM) combined with moving least square method (MLSM) and genetic algorithm (GA) were used. Furthermore mechanical stress on the rotor was verified by structural analysis.
