Excess Loss Localization on the Hysteresis Curve

Excess Loss Localization on the Hysteresis Curve

Two alloys of nonoriented electrical steel, with 2.45 and 3.3%Si, respectively, had their magnetic properties characterized in an Epstein frame. Hysteresis curves for total, quasi-static, and parasitic losses were plotted and overlapped to identify the region where the anomalous loss happens. It was...

Zusammenfassung:Two alloys of nonoriented electrical steel, with 2.45 and 3.3%Si, respectively, had their magnetic properties characterized in an Epstein frame. Hysteresis curves for total, quasi-static, and parasitic losses were plotted and overlapped to identify the region where the anomalous loss happens. It was observed that most anomalous loss is from the domain wall movement's region and a smaller contribution from nucleation and annihilation regions.
