Abstract: Based on J-MAG, a multi-objective optimization finite element model was established, parameterized the key dimensions and positions the stator and rotor laminations, that affect the motor performance in the topology.Used the genetic optimization algorithm embedded in the software, the single-objective performance of the motor was optimized, and the torque ripple, output torque and tooth groove torque were taken as the objective functions of the motor optimization.The correlation between different performance indexes was analyzed.Used the weighted index, the influence of torque ripple, output torque and tooth groove torque on the vibration and noise performance of the motor was comprehensively considered, the optimal design scheme was obtained.The effectiveness of the optimization scheme was verified by experiment.

Key words: multi-objective, parameterization, genetic algorithm, optimal design
