停止模型与一维有限差分法或均匀化法相结合来表示硅钢片的磁滞特性。没有过量涡流损耗的涡流分析无法给出准确的涡流场。 ac B--H 回路的表示通过增加电导率得到改善，该电导率是通过 Pry 和 Bean 模型的过量损耗评估获得的。
A stop model is combined with a one-dimensional finite-difference method or a homogenization method to represent ac hysteretic characteristics of a silicon steel sheet. Eddy-current analysis without excess eddy-current loss fails to give an accurate eddy-current field. Representation of ac B--H loops is improved by increased conductivity that is obtained from an excess loss evaluation by the Pry and Bean model.
