Abstract :
This paper presents an extended finite element based model approach for permanent magnet synchronous machines considering dynamic eccentricity effects of the rotor. This includes additional displacement forces acting on rotor and stator as well as the influence of rotor eccentricity to the machine torque and the back electromotive force. Furthermore, the work flow for this model is shown.
