Abstract

This paper presents a finite element-based circuit model approach for permanent magnet synchronous machines, electrically excited synchronous machines, and wound rotor induction machines, taking skewing of the rotor or the stator into account. These models utilize lookup tables created by 2-D finite element simulations in advance. Inspired by the finite element multislice technique, a multiple evaluation of these lookup tables is performed to consider skewing. The resulting models are comparable with quasi-static finite element multislice models with voltage fed coils. The only difference is caused by interpolation errors. However, the simulation cost is significantly lower and the memory demand for the lookup tables is acceptable.
