Dynamic Magnetization Model of Nonoriented Steel Sheets

摘要

A simplified model of conducting ferromagnetic sheet, which describes magnetization of isotropic electrical steels is proposed. The model improvement is achieved by determining eddy current component of the magnetic field at the sheet surface in the framework of the method by Wolman and Kaden, which describes the dynamic magnetization of the material with rectangular hysteresis loop. An algorithm of model fitting is proposed and a comparison of calculated and experimental results has been carried out.
