A novel method of modeling 2D magnetic properties of electrical steel sheet in electromagnetic devices

摘要

This paper presents a material modeling method of silicon steel sheet considering harmonic magnetic field in the model. A new experiment method that can provide magnetic property data of high-order harmonic magnetic field is introduced. A material modeling method associated with the measurement data is provided. A novel time periodic iterative method of finite element analysis (FEA) is proposed to consider dynamic magnetic property.
