Improved Energy-Based Hysteresis Model and Parameter Identification for Magnetic Hysteresis Materials

This paper aims first to clarify the transition between the thermodynamic balance from the mesoscale, at the scale of one cell, to the macroscale, at the homogenized level. Actually this homogenization can be tackled in different ways, leading to different construction of EB hysteresis loops, one approach being in better agreement with experimental data. Then, the observed asymmetry between ascending and descending branches in measured hysteresis loops, which cannot be accounted for by the original EB model, is further investigated. An extension of the EB model is proposed and a comparison with classical Jiles-Atherton results to material measurements will be shown. Additionally, the parameter identification technique will be adapted accordingly in the full paper.FEDO (Free Software for Electric Drive Optimization
