Abstract

This article studies different stator structures and modeling methods for using grain-oriented electrical steels (GOES) to improve the performance of high-power-density permanent magnet synchronous motors (PMSMs). The magnetic characteristics of GOES samples are measured under magnetizations at different angles and frequencies. Models of various GOES stator teeth and yokes are established. The effects of different GOES stators on PMSM performance are studied, and their advantages and disadvantages are compared. Three typical GOES PMSM prototypes are fabricated and tested to demonstrate the superiority of GOES stators and validate the effectiveness of the established models.
Keywords: PMSM; grain-oriented electrical steels; magnetic property; stator topology; models of GOES PMSM; grain-oriented electrical steels; magnetic property; stator topology; models of GOES
