Abstract

The procedure of 3-D finite element meshing for skewed rotor induction motors has been developed. In this method, the mesh distortion caused by the rotor-node rotation for skew modeling is reduced using the iterative node displacement and element swapping. The advantages and necessity of the proposed method are confirmed by comparing the conventional mesh-generation method and motor experiments. It is revealed that the accuracy of the calculated loss is considerably deteriorated by the distorted mesh and it is significantly improved by the proposed mesh-generation procedure.
