In this study, we explore the vector magnetic properties of the electrical steel sheet under dc-biased flux and rotating magnetic field of different frequencies. The corresponding iron loss and the rotational eddy current loss are discussed. An enhanced vector magnetic hysteresis model is proposed to describe the $B$ – $H$ behavior under these conditions. The accuracy of the proposed model is verified by the close agreement between the hysteresis loops calculated with the proposed model and those measured experimentally, as well as by the neglectable calculation error of the total iron loss.

直流偏置磁通和变频旋转磁场下电工钢板的矢量磁特性

在这项研究中，我们探索了电工钢片在直流偏置磁通和不同频率旋转磁场下的矢量磁特性。讨论了相应的铁损和旋转涡流损耗。提出了一种增强的矢量磁滞模型来描述 $B$ —— $H$ 在这些条件下的行为。所提出模型的计算结果与实验测得的磁滞回线非常吻合，总铁损的计算误差可忽略不计，从而验证了所提出模型的准确性。
