Abstract

This paper presents a multiphysics modeling and design methodology for high speed permanent magnet synchronous motors (PMSM) for electric traction applications. In this proposed methodology, the electromagnetic, thermal and mechanical fields are coupled together. The electromagnetic model is used to analyze the electromagnetic performances and losses of the PMSM, which then feed the thermal and mechanical models. The thermal model focuses on the machine’s temperature rise while the mechanical model is used to analyze the stress distribution of the PMSM. Combined together, a powerful multiphysics model aimed for the design of high speed PMSMs is achieved. The design results prove that the designed PMSM can simultaneously meet the requirements of high power density, high temperature and high reliability.
