7.1.2.5.5 Magnetic loss dependence on grain orientation, sheet thickness, stress

Abstract

This chapter illustrates magnetic loss dependence on grain orientation, sheet thickness and stress of grain-oriented (GO) silicon steels. 50 Hz power loss at various peak inductions versus average misorientation angle of high-permeability grain-oriented (HGO) silicon steels is shown. Power loss at 1.7 T peak induction and 60 Hz versus induction at 10 Oe for 0.30 mm and 0.35 mm thick specimens, and power loss at 1.7 T peak induction versus sheet thickness for various GO silicon steels are illustrated. Thickness dependence of power loss for chemically polished specimens for HGO silicon steels is shown. Power loss versus applied stress is demonstrated for various peak inductions measured on conventional and high-permeability silicon steels. Total and hysteresis loss at 1.5 T peak induction and 50 Hz versus applied tensile stress for conventional and HGO silicon steels, and effect of compressive stress on the dynamic hysteresis loop of GO silicon steels are illustrated. Angular dependence of 1.0 T power loss for various tensile and compressive applied stress for GO silicon steels is figured out. The effect of surface coating on power losses of HGO silicon steels is also figured out.
