Contrary to internal combustion engine vehicles, electric vehicles (EVs) obtain
the power required for the compressor of the air conditioning system from the electric compressor. Therefore, the optimal design of the electric motor, the main component of the electric compressor, is essential to improve the EV mileage. A multi-objective optimal design is required, because the characteristics of the motor are in a trade-off relationship with each other. When the finite element method (FEM) is used, multi-objective optimal designs of the motor take significant time because of the diversity analyzes required for the optimal model search. To solve this problem, in this study, using the NSGA-II and analytical method, a multi- objective optimal design method of SPMSM for EVs air conditioner system compressor was proposed and applied. The validity of the proposed method was secured by comparing the characteristics of the optimal design model with those of initially designed model.
