Zusammenfassung

With the emergence of electric vehicles (PHEV, MEV, BEV and FEC) and the significant reductions of permanent magnet material and its related cost, new challenges arise in the design of electric machines. Particularly related to size and weight along with attributes such as higher torque and power density which has led to the need to develop improved cooling to avoid overheating. This implies a strong need for multiphysics analysis, namely electro-magnetic in combination with thermal. 
In this paper we present a novel approach using a finite volume discretization technique to a 2D section of an electric machine and obtain the magnetic field and loss distribution and exchange the data with the full 3D CFD thermal model in a single user environment.
