Vector Hysteresis Modeling Coupled with a Loop-based Magnetic Equivalent Circuit [PDF]
2021 Sixteenth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2021 This paper proposes a method to include the anisotropic magnetic hysteresis property of the soft-magnetic material in the magnetic equivalent circuit (MEC) modeling. The loop-based MEC formulation is improved to handle the non-linearity of the anisotropic magnetic hysteresis.
