Vector Hysteresis Modeling Coupled with a Loop-based Magnetic Equivalent Circuit

“…The loop-based MEC uses Kirchhoff's voltage law to calculate its pseudo flux loops. The authors have recently used this method to model the iron parts of a variable flux reluctance machine [9]. The magnetic saturation is modeled in MEC using two different approaches: the single-valued BH curve (SVC) and the vector hysteresis BH loop (HL).…”

“…In this study, the formulation of the loop-based MEC model used in [9] is improved to couple the existing MEC model with the anisotropic vector hysteresis model presented in [10]. The system of equations of the coupled model is solved iteratively using only the fixed-point method for a single MEC element under a magnetic field with various magnitudes and frequencies.…”

A Novel Modeling Technique via Coupled Magnetic Equivalent Circuit With Vector Hysteresis Characteristics of Laminated Steels

“…In this study, the formulation of the loop-based MEC model used in [21] is improved to couple the existing MEC model with a dynamic version of the anisotropic vector hysteresis model (VHM) presented in [22]. The proposed approach is able to simulate the anisotropic and dynamic magnetic characteristics of laminated steels, including the hysteresis, classical eddy-current and excess fields in transient instead of using the SVC in magnetostatic.…”
