Consideration of rotor eccentricity effects in a multi body dynamics simulation using a finite element based circuit model approach

Abstract

This paper presents a finite element based circuit model approach for a permanent magnet synchronous machine considering rotor eccentricity effects. The presented model is well suited for multi body dynamics simulations, because it combines the coverage of saturation, slotting and eccentricity effects that is typically known from finite element models with a very low simulation cost. The focus of this work is on the validation of the proposed model. For this purpose several comparisons between the proposed model and transient finite element simulations with motion have been carried out.
