This paper illustrates the state of art of magnetic testing of electrical steels under distorted flux wave forms, gives comparisons of performance of various motor steels and introduces a loss prediction approach based on the linear relationship between iron loss produced under sinusoidal flux and that produced under pulse width modulated (PWM) excitation. Results are very promising showing agreement between measured and predicted losses in a wide range of electrical steels magnetized under various PWM wave forms to within 5%.
