Thermal Analysis of Water-Cooled Permanent Magnet Synchronous Motor for Electric Vehicles

Abstract:

In order to study heat generation and dissipation of water-cooled permanent magnet synchronous motor in electric vehicle, the major energy loss was calculated and the finite element model for interior heat transfer simulation was established based on appropriate simplification and equivalent processing. The fluid-solid-thermal coupling simulation was accomplished by CFD method and the steady state temperature field of the motor under rated condition was obtained. The simulation is verified by experiment and gives an effective support in motor’s cooling system design.
