“…Accurate studies on core losses at high frequencies require skin effect and its consequences on the magnetic properties of the magnetic cores taking into account. [2][3][4][5][6][7][8][9][10][11][12][13][14]; non-uniform flux density distribution has been considered in some of these methods [2][3][4][5][6]. Different methods have been also reported based on equivalent circuits of magnetic laminations to predict the magnetic properties of cores [15][16][17].…”

This paper investigates the influence of a wide range of magnetising frequency and peak flux density on the magnetic properties of the electrical steels. In the relevant studies some important factors and operational properties, e.g. skin effect, nonuniform flux density distribution, complex relative permeability and magnetisation characteristic of the material, which are often neglected in the literature, are highlighted. Analytical modelling and experimental works were performed for 3 % grain oriented silicon steel. In order to show the impact of peak flux density on the magnetic properties, two peak flux densities 1.3 T as a high permeability point and 1.7 T as a low permeability point were considered. The results highlighted that magnetising frequency and peak flux density are two determinant factors with significant effect on the magnetic properties of electrical steels.
