As a magnetic core material, non grain oriented (NGO) electrical steel is mainly characterized by its magnetic properties, i.e. the specific loss, the magnetic saturation polarization, and the magnetizability, i.e. the permeability. In addition, mechanical properties, e.g. manufacturability, yield strength as well as coatings strongly influence the performance, power density and the cost of the resulting electric machine. This paper presents the effect of various cutting techniques on the material behavior of high-strength NGO electrical steel grades with guaranteed yield strength in rolling direction of 400 - 600 MPa in thickness 0.30 - 0.35 mm. Typical application fields of this material are automotive traction drives with their specific application range at higher frequencies than 50 Hz.
