This study presents a numerical modeling of vector (two-dimensional) magnetic properties considering hysteresis of silicon steel sheets. We define the magnetic reluctivity tensor newly and calculate them from the measurement data obtained by two-dimensional magnetic measurement. Our new modelings, which are "E＆S Model" and "E&S^2 Model", can be introduced into a finite element formulation for magnetic field analysis and can get the distribution of the magnetic field strength H-vector and the magnetic flux density B-vector.In this study, two kinds of new modelings for vector magnetic properties for nonlinear iron loss analysis have been presented. We can analyze a three-phase transformer core model considering both the alternating and the rotating hysteresis. Moreover, it can be said that the presented methods are very useful to analyze electrical machines and apparatus considering vector magnetic properties.

本文提出了一种考虑硅钢片磁滞回线的矢量(二维)磁性能数值模型。我们重新定义了磁阻张量，并根据二维磁测得到的测量数据计算了磁阻张量。我们的新模型“E&S模型”和“E&S^2模型”可以被引入到磁场分析的有限元公式中，得到磁场强度H矢量和磁通密度B矢量的分布。我们可以分析同时考虑交流磁滞和旋转磁滞的三相变压器铁心模型。此外，可以说，所提出的方法对于考虑矢量磁特性的电机和设备的分析是非常有用的。
