Adaptions of the Energy-Based Hysteresis Model for correct Rotational Losses

Energy-based (EB) hysteresis models are thermo-dynamically consistent formulations for the physical process of magnetic hysteresis and can efficiently be used in Finite Element (FE) implementations. However, a shortcoming of classical EB models is the correct modelling of vanishing rotational losses in the range of saturation. In this contribution, two adaptions of the EB model are presented, by which rotational losses can qualitatively be included into the model. The proposed adaptions are included in a FE simulation of a rotating magnetic field and compared to simulations of a classical EB model.
