“…In order to predict the iron-loss and magnetization behavior under such conditions accurately, it is indispensable to utilize a hysteresis model that is coupled directly to an eddy-current (lamination) model. This can be solved by using various approaches, where the lamination model is, e.g., based on Maxwell equations [9], [11], [23], [24], [27]- [36], [38]- [57], saturation wavefronts [58]- [60], equivalent circuits [37], [48], [61]- [63] or is included in the hysteresis model implicitly [43], [64], [65]. A comparison of different 1-D lamination models in terms of mathematical structure, implementation, computational performance, accuracy and spatial discretization can be found in [48].…”

This paper presents a thorough introduction to and application of the Parametric Magneto-Dynamic (PMD) model of soft magnetic steel sheets. The theoretical background is reviewed, and two different ways are discussed to account for the viscosity-like effects originating from microscopic eddy currents. This is followed by the theoretical calculation of magnetization dynamics and dynamic hysteresis loops in Non-Oriented (NO) electrical steel. Both classical and viscosity-extended approaches are discussed, with respect to the ability of replicating the dynamic hysteresis loop shape and iron-loss under sinusoidal excitation waveforms up to high excitation frequencies. Comparisons against measurements are analyzed for M400-50A and M235-35A NO electrical steel over a wide range of magnetic flux density and excitation frequencies. The proven accuracy and efficiency of the PMD model make it a valuable tool for the calculation of iron losses in electrical machines and transformers, as well as for an in-depth study of magnetization dynamics in individual laminations.

This paper introduces the latest research achievements on the hysteresis modeling for power magnetic devices based on the magnetic circuit method. First, the magnetic circuit model considering the magnetic hysteresis behavior is derived. Next, this magnetic circuit model is developed to the reluctance network model, to analyze more complicated devices such as an electric motor. Furthermore, this magnetic circuit model is improved to take the dynamic hysteresis characteristics including the skin effect into account. Finally, the prediction method of the deteriorated hysteresis loops in core material due to machining process is established.

“…A description of the behaviour of nonlinear electric circuits with magnetic cores employed in electric machines during steady-state and transient working regimes usually requires knowledge of the magnetic characteristics of the material used (magnetisation curve, i.e., the φ = φ(i) (magnetic flux vs. current) dependence, hysteresis loops, power losses, etc.) [1][2][3][4][5][6][7][8]. Such an electric circuit can alternatively be represented by: (1) an inductance L exhibiting a single-valued (SV, thus neglecting hysteresis) magnetisation curve connected in parallel to a resistance R [1], (2) a dynamic hysteretic core model [1] or (3) an electric network (such as a Cauer circuit [3,4]).…”

The aim of this paper is to present a methodology for the calculation of the R-L parameters of a model of a nonlinear hysteretic inductor. The methodology is based on the analysis of the instantaneous magnetising power calculated from the hysteresis loop of the inductor and is completely developed in the time domain. The instantaneous magnetising power is firstly separated into the oscillatory and absorbed components. Thereafter, the parameter R is calculated using the absorbed component and the parameter L using the oscillatory component. The methodology is validated through the comparison of the results for parameters R and L obtained with the proposed method and the existing method based on the Poynting theorem. The validation is demonstrated on the specific simulated cases with idealised parameters of a nonlinear circuit. Additionally, the paper presents results for the parameters R and L calculated from the hysteresis loops measured at frequencies from 1 to 300 Hz. Furthermore, the fitting functions representing the variation of these parameters with the rate of change of magnetic flux density, and the corresponding results, are presented in the paper. A discussion of all the results presented and applicability of the methodology proposed, as well as the concluding remarks, are given thereafter.
