Abstract :
This paper deals with the magnetic forces and the mechanical behavior of flux switching permanent magnet (FSPM) machines. First, we will focus on the origin of magnetic stresses in the FSPM machine. Secondly we will realize a FEM analysis to observe these stresses in two locations (at the air / teeth interface and at the permanent magnets / iron interface) when the FSPM machine is unloaded and loaded. Then, we will consider the expression of the stator deformation. Finally, eigenmodes of this structure obtained by FEM analysis will be presented and compared to experimental measure.
