Design Method of IPMSM with Multi-Operating Points Considering Multi-Physics for High-Speed Electric Vehicles

Various performance targets and imperative constraints are required for electric motors aimed at high-speed electric vehicles. However, there are some analysis and time cost issues for designing high-speed motors. Because multi-operating points and multi-physics analyses should be conducted. Therefore, an appropriate design method is needed to design the motors. In this study, we propose a design method for high-speed motors with multiple objectives and constraints considering multi-operating points and multi-physics by the finite element method and an NSGA-II-based optimization algorithm.
