Abstract

Synchronous reluctance motor (SynRM) attracts attention because of high price of rare earth in recent years. In order to improve its torque characteristics, optimization of the rotor core structure using topology optimization has been reported. However mechanical performance such as rigidity may be deteriorated. In this paper, coupled topology optimization method based on magnetic and structural analysis of electrical machine is verified in the SynRM. As a result, optimized structure with high equipment rigidity was obtained while maintaining the torque characteristics.
