Abstract

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.
