Separating Components of the Hysteresis Loss of Non-Oriented Electrical Steels

Abstract

This paper shows that the separation of quasi-static hysteresis losses into two components, one related to Low Induction and other to High Induction levels. The separation line between those two regions has been arbitrarily chosen as the induction at maximum permeability. Results show that the grain size has stronger effect on the low induction component, while the high induction component is more sensitive to sample measuring direction. This may provide basis for better materialsproperties correlation modeling and product development.
