Improvement of Integration-Type Dynamic E&S Modeling

This paper presents an improved integration-type E&S modeling for applications under high magnetic flux density conditions. In the conventional integration-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 the rotational magnetization process around the saturation region (1.5-1.8 T). The integration-type dynamic E&S modeling was improved with the measured database, and the verification with a simple problem for high magnetic flux conditions was demonstrated in this paper.
