Abstract

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