Abstract

This paper presents an improved integral-type E&S modeling for applications under high magnetic flux density conditions. In the conventional integral-type dynamic E&S modeling, we assumed linear increment of higher harmonic components including in the magnetic field strength waveforms versus the magnetic flux density. However the higher harmonic components decrease after getting a peak value in rotational magnetization process around saturation region (1.6T - 1.8T). Improvement of the integral-type dynamic E&S modeling for the high magnetic flux conditions was investigated in comparison with the measured one and verification with a simple problem was demonstrated in this paper.
