Several modeling methods for representation of AC magnetic properties of electrical steel sheets taking account of skin effect

AbstractSeveral homogenized models are compared for accurate representation of the AC magnetic properties of silicon steel sheets. Two of them are the generalized Pry and Bean models, which have a parameter for the frequency dependence of eddy‐current loss. The third model assumes a quadratic distribution of the magnetic flux density along the thickness direction. The other model is an extension of the linear magnetization model. Numerical simulations show that the third model yields inaccurate BH loops whereas the other models accurately represent BH loops. © 2011 Wiley Periodicals, Inc.
