Summary of calculation methods of PMSM iron loss based on finite element analysis

Abstract

Since the birth of the motor, the accurate calculation of the iron loss of the motor has always been a big problem in the field of motor design.Too many factors affect the change of the iron loss of the motor, which is the main reason why it is difficult to accurately calculate the iron loss of the motor.The traditional magnetic circuit method and the finite element method are the two main ways to calculate the iron loss at present. In this paper, various iron loss calculation models in the finite element method are summarized and introduced,and the advantages of each model are compared.
