Abstract

All electrical vehicle (EV) components are subject to significant constraints in term of efficiency, noise, performances and weight. This is notably the case of electrical compressors used for battery cooling and EV cabin thermal comfort. To drive such applications, permanent magnet synchronous motors (PMSM) are considered as attractive structures. That is why in previous work [1], a PMSM was designed and prototyped for an electrical compressor. In this paper, structural and cogging torque improvements of the studied PMSM are proposed in order to reduce the compressor total noise. A finite element method is used for this study.
