3-D thermal model of an hybrid excitation flux switching synchronous machine using a 2-D FE method software

After introducing the structure of the studied electric machine, we present the elements necessary for thermal modeling. We present the sources of losses and the elements of thermal conduction and thermal convection. We use a 2D FE method software named `'femm''. For 3D modeling, we begin by transforming the complex structure of the stator in a set of concentric cylinders. The axial thermal study is done on the half machine, because there is symmetry of thermal elements. In the discussion section, we present the temperature distribution and the heat flux inside the machine.
