Static hysteresis modeling for grain-oriented electrical steels based on the phenomenological concepts of energy loss mechanism

This paper proposes an advanced approach to construct static hysteresis loop of Grain-Oriented (GO) electrical steels for dynamic modeling and energy loss analysis. The proposed is in line with the magnetic phenomenological concepts rate-dependent rate-independent components ferromagnetic materials under time-varying fields. method can predominantly describe mechanism magnetization processes material. Accuracy this technique was validated on Epstein size laminations 3% GO silicon steels. results explicitly confirmed effectiveness at magnetizing frequencies up 1 kHz peak flux densities 1.7 T.
