An Anisotropic Hysteresis Model Considering Microstructural Feature

This paper introduces a physically-based anisotropic hysteresis model considering the microstructural features of non-oriented silicon steel. Drawing on the foundations of the Globus' model, the anisotropic anhysteretic curve is first deduced from the movement of the domain wall within individual grains. A static anisotropic hysteresis model is then proposed by considering the grain size related pinning field in the Energy-Based (EB) model to describe the irreversible displacement. The accuracy of the proposed model is validated through a detailed comparison with experimental data.
