“…Important advantages are the physical interpretation attributed to its parameters and the possibility to incorporate different physical phenomena in the description within the framework of "an effective field". Despite some of its weaker points (non-closure of minor loops for complicated magnetization patterns and the necessity to "patch" model equations in order to describe material behavior after a field reversal [22][23][24], this description remains one of the most commonly used hysteresis models in the practice.…”

Soft magnetic composites are readily used in the design of electromagnetic converters and electrical machines. In the paper, the magnetic properties of "home-made" cores made of iron powder and suspense polyvinyl chloride are examined. Samples were prepared by hot pressing of a PVC/Fe powder mixture with a different ratio of constituent components. Phase composition was investigated using an X-ray diffractometer and the presence of α-Fe was detected. Measurements of magnetic permeability revealed its allometric decrease with an increase of PVC content in composite. For the description of magnetization curves the phenomenological Jiles-Atherton model is used. The results of simulations are in a qualitative agreement with experiment.

“…In order to deal with this issue, several improved static models have been proposed to take into account the influence of B max [15], [23], [24], [25]. However, none of these improved models are used in our work as they are not consistent with the dynamic Jiles-Atherton described above.…”

This paper describes a mathematical model for the dynamic magnetic power losses in the laminated steel stator of high frequency permanent magnet machines, such as Brushless DC (BLDC) Motors. The model presented is based on a utilization of the dynamic Jiles-Atherton model. Accurate dynamic BH curve fitting and magnetic power loss derivations have been achieved, where the calculated magnetic losses have shown around 95% accuracy from 5 Hz to 2000 Hz, over a flux density range of 1.0 T to 1.6 T. This approach has been applied to estimate the magnetic power loss of a small scale, high frequency (>10,000 rpm) BLDC motor, with calculated and measured losses being in close agreement.

“…At the same time several authors realized that in order to obtain a reliable representation of more complex magnetization cycles, including minor loops, reversal curves etc. it would be necessary to update the values of model parameters in accordance with certain functional dependencies [6,10,[17][18][19][20]. The abundance of different model versions and the focus set mostly on the advantages of one estimation method over another have blurred serious problems with the model equations themselves.…”

Abstract. The paper considers a qualitatively different behaviour of two phenomenological hysteresis models. The first one is the widespread Jiles-Atherton description, which is based on the "effective field" concept. The other model is the proposal by the Brazilian research team GRUCAD. First order reversal curves simulated with the latter formalism do not exhibit negative slopes. This feature is in accordance with the experiment.
