In this paper, we apply an anisotropic extension for the energy-based and the Jiles-Atherton 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 Jiles-Atherton 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.
