Thermal Study Comparison of Permanent Magnets Machines Using Finite Element Method (FEM) Electric Vehicles Application

The thermal behavior of electrical machines is a crucial step in design. To have a complete model it is necessary to compute and evaluate the temperature in different parts of the machines (winding, magnet, rotor and stator yoke). This study is achieved using finite element method (FEM), temperature distribution in two machines with different shape of magnets are considered in this study. This work is done in collaboration with PSA. This paper deals with thermal management aspects of electrical machines used in high performance applications with particular focus on electric machine designed for electric vehicles. The comparison is done for PM machines with V and I shape, the electromagnetic performances of these machines are already computed.
