Analysis of the grain oriented electrical steel heterogeneities and their influence on the Epstein frame loss measurements

Résumé

The Epstein frame is a well-known standardized system used to characterize soft magnetic materials. The users of this device usually consider that all the strips of a same grade placed in the frame are homogeneous, and they do not take into account the potential impact of the heterogeneity of the sheets on the quality of the characteristics deduced from the measurements. The aim of this paper is to quantify the individual heterogeneity of Epstein samples of the same FeSi grade (BH curve, losses, permeability), and to analyze, by both experimental and numerical ways, if the layout of the sheets can impact the Epstein core losses.
