Experimental Study on the Iron Loss Curve at High Field Strength of Non-Oriented Electrical Steel Sheet

Abstract:

At high AC field strength, BH loop tends to twist slightly near the tip point. It results in apparent decrease of iron loss because the overturned parts introduce negative iron loss value. In order to correct this error the phase difference between flux density and magnetic field strength needs to be eliminated. We studied on the problem and got satisfactory results.
