Abstract
Non-oriented (NO) soft magnetic steel sheets (SMSSs) exhibit specific properties such as saturation due to material properties and dynamic hysteresis due to induced eddy currents. Modeling of magnetization dynamics, transients and iron losses in laminated structures is a complex problem, still open nowadays and of critical importance in different areas of applied research. The quantitative description of the magnetization process in thin and long sheets neglecting edge effects can be reduced to the integration of 1-D penetration equation [1, 2]. In this paper, however, this problem is solved using the parametric magneto-dynamic (PMD) model [3, 4]. This model offers the flexibility to implement various inverse hysteresis models to analyze their ability to handle the intricate problem. The applied hysteresis model to represent the constitutive relation of the SMSS plays a central role for the resulting eddy current and flux distributions due to different magnetization trajectories in different layers of the sheet.
