| Abstract: | The inherent shaft voltage mechanism of the stator permanent magnet (Stator-PM) machines represented by the flux-switching permanent magnet(FSPM) machine is analyzed.Both the 2D and 3D finite element analysis models are developed and simulation is carried out for different speeds,shaft structures and materials,rotor eccentricities and armature currents.Finally,the experiment on 10-rotor-pole and 12-stator-slot FSPM machine verified the correctness of analysis and simulation.The results will be helpful to design and reliability analysis of high speed permanent magnet machines. |
