Multiphysical modeling and description of a permanent magnet synchronous machine using energetic macroscopic representation for EV/HEV applications

Because it does not participate in the vehicle traction, the thermal energy is not highlighted in the electric and hybrid electric vehicle (EV and HEV) study, especially for electrical components like electric machines and batteries. Nevertheless, the thermal states of these components can have a great impact on the vehicle behaviour, such as safety, performances and autonomy, etc. This impact is more important if the driver turns on the heating system. In order to consider the thermal dimension of the energetic study for EV/HEV applications, a multiphysical modeling and description (for organizing this model with the energetic focus) of each component is required. This paper is focused on the multiphysical (electrical, mechanical and thermal) modeling and description of the electrical machine using EMR.
