Abstract
This paper enhanced the integration-type E&S model and the dynamic E&S model for integrating the impact of DC-biased field and eddy current on vector magnetic properties of electrical steel sheet. B and H of electrical steel sheet are measured under DC-biased and rotating fields. Based on the measured results, the databases of reluctivity and hysteresis coefficients of both the enhanced integration-type E&S model and the improved dynamic E&S model are established for predicting H waveform under any given operating condition. By comparing the H waveform calculated by the enhanced integration-type E&S model and the improved dynamic E&S model with the experimental H waveform, it is found that both two models have good reliability and the improved dynamic E&S model has slightly better accuracy than the enhanced integration-type E&S model.
