Normal permeability of grain non-oriented,grain oriented and amorphous electrical steel sheets

Abstract

This paper presents the normal permeabilityμ _z of different grades of electrical sheets (Grain oriented, non oriented and amorphous). A specific test bench allows determining the intrinsic static B(H) cycle. The magnetization in static mode makes it possible to suppress the eddy current influence, contrary to others classical methods. The B–H curves of different materials are provided up to the saturation and the μ _z permeability can be directly implemented in Finite Element software applications.
