Comparison of Anisotropic Energy-Based and Jiles–Atherton Models of Ferromagnetic Hysteresis

Abstract

In this article, we apply an anisotropic extension for the energy-based and the Jiles–Atherton (JA) hysteresis models to simulate both unidirectional alternating and rotational magnetic field excitations. The results show a good agreement with measurements for unidirectional alternating fields. However, the results for rotational fields, especially at high magnitudes, show a significant discrepancy with the measurement data. We demonstrate that the JA model with appropriate parameters can estimate the losses in alternating cases up to 1.5 T, whereas both models give reasonable loss estimation up to 1 T in rotational cases.
