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

摘要

This paper presents the normal permeability μ_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.
