Finite Element Modeling of Induction Motor for Variable Speed Drives

Purpose – The purpose of this paper is to present a new finite element technique to simulate variable speed drives. Design/methodology/approach – The induction motor (IM) is simulated according to the adopted control strategy. This allows use of only magnetostatic simulation for both no-load and under-load simulations. Findings – The procedure allows the analysis of the performance of the IM drive taking into account iron saturation in all operation points. Originality/value – The entire system design is considered in the paper, both the electrical machine and the control strategy
