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.

基于各向异性能量的铁磁磁滞模型与 Jiles-Atherton 模型的比较

在本文中，我们对基于能量的和 Jiles-Atherton (JA) 磁滞模型应用各向异性扩展来模拟单向交变和旋转磁场激发。结果显示与单向交变场的测量结果非常吻合。然而，旋转场的结果，特别是在高震级时，与测量数据存在显着差异。我们证明了具有适当参数的 JA 模型可以估计高达 1.5 T 的交​​替情况下的损失，而这两种模型都可以在旋转情况下给出高达 1 T 的合理损失估计。
