“…However, it is approved that the Jiles-Atherton theory of anhysteretic and hysteretic magnetization didn't give correct frequency dependent modelling [25]. Recently, dynamic loss inclusion in the Jiles-Atherton hysteresis model using the field separation approach has been published [26]. In order to model frequency dependent hysteresis loops correctly it is necessary to have real loops obtained by measurements performed on toroidal magnetic core of the investigated material.…”

In this study the characterization of FeCo-2V alloys toroidal samples produced by PIM/MIM technology was presented. The feedstock for metal injection molding (MIM) was prepared by mixing starting FeCoV powder with a low viscosity binder. Green samples were subjected to solvent debinding and subsequent thermal debinding followed by sintering. Sintering was performed during 3.5 hours from 1370 o C to 1460 o C in hydrogen atmosphere in order to attain the appropriate mechanical and magnetic properties. Microstructure, hardness HV10 and magnetic hysteresis B(H) were investigated as a function of sintering temperature. Optimum combination of functional properties was observed after sintering at temperature of 1370 o C. In addition, magnetic properties were analyzed as frequency dependent and successfully simulated in operating frequency range from 5 Hz to 60 Hz.

The modelling of the dynamic behavior of hysteretic materials and devices must take into account magnetodynamic effects. In the present paper these tasks are simultaneously modelled by means of an ad-hoc Neural System (NS) based on an array of 3-input 1-output Feed Forward NNs. Each NN is aimed to a particular typology of the excitation field (prediction of flux density from a known waveform of the magnetic field strength or vice-versa) and manages just a fixed portion of the dynamic hysteresis loop. The whole hysteretic curve is simulated by linking the evaluations made by different NNs of the NS. The NS is able to perform the simulation of any kind of dynamic loop (saturated and non-saturated, symmetric or asymmetric) generated by any assigned arbitrarily distorted excitations into a fixed range of frequencies. Numerical validations are presented both on a "virtual magnetic device" and on a non-oriented Fe-(3 wt%) Si laminations (thickness 0.35 mm

In this paper, dynamic formulation for energetic model proposed by H Hauser of ferromagnetic hysteresis is compared with the Jiles‐Atherton model that has been applied for hybrid magnetic field formulation. This model is based on the concept of the losses separation method. The energetic model is suitable for quasistatic ferromagnetic hysteresis and to improve this model in dynamic behavior, we modify the total energy given by the energetic model by introducing 2 additional energies associated with classical eddy and excess losses. Two new parameters related to eddy and excess losses are introduced. The identification of these parameters is achieved by measuring the volumetric energy density. All parameters are kept constant regardless of the used frequencies. The validity of this approach is justified by comparison of calculated hysteresis loops to measurements for different frequencies, and good agreements are obtained.
