This paper presents the measurement and numerical simulation results related to the iron loss components occurring in lamination sheets used to build cores of ac electric motors. The research is focused on the analysis of changes in the Steinmetz coefficients describing the material iron loss, as a function of the distance from the cut edge. The authors used an ad-hoc FEM model that takes into account the changes in the magnetic permeability and electrical conductivity of the material, which are a consequence of the used cutting technology. The analysis has been performed for three commercially available low-loss magnetic laminations having a thickness of 0.35 mm.

Abstract

This paper presents the measurement and numerical simulation results related to the iron loss components occurring in lamination sheets used to build cores of ac electric motors. The research is focused on the analysis of changes in the Steinmetz coefficients describing the material iron loss, as a function of the distance from the cut edge. The authors used an ad-hoc FEM model that takes into account the changes in the magnetic permeability and electrical conductivity of the material, which are a consequence of the used cutting technology. The analysis has been performed for three commercially available low-loss magnetic laminations having a thickness of 0.35 mm.
