本文建立了无取向软磁钢板的一维动态磁化模型，该模型可表示为简单的常微分方程组。所讨论的模型考虑了涡流和磁滞对磁化强度的动态影响，但在求解含磁滞的耦合麦克斯韦方程组的方法上有所不同。提出的建模方法包括不同精度的有限差分格式，各种磁等效电路（MECs），包括一种消除经典磁等效电路缺陷的新方法，以及一种无网格方法。在数学结构、实现工作、空间离散化和精度方面，对不同的建模方法进行了分析和比较，并对电压驱动和电流驱动两种版本进行了研究。
This paper presents 1-D dynamic magnetization models of non-oriented soft magnetic steel sheets that can be expressed as simple systems of ordinary differential equations. The discussed models take into account the dynamic effects on magnetization due to eddy currents and hysteresis inside such sheets and differ in the way the coupled Maxwell equations with hysteresis are solved. The presented modeling approaches include finite-difference schemes of different accuracies, various magnetic equivalent circuits (MECs), including a recent approach to eliminate the deficiencies of classical MECs, and a mesh-free approach. The different modeling approaches are analyzed and compared in terms of mathematical structure, implementation work, spatial discretization, and accuracy, where both voltage- and current-driven versions are investigated.
