Model for the behavior of magnetic materials hysteretic taking into account the temperature

Abstract

The work is to develop a model for magnetic hysteresis taking into account the temperature. We introduced the effect of temperature through behavior as a function of temperature settings and model Jiles Atherton. The results of the model in terms of saturation induction, remanent induction, coercive field and the evolution of hysteresis cycle as a function of temperature are accort with theory and with results given in [1]. A program for calculating field incorporating model hysteresis to study a system of induction heating is also necessary. This program of resolution was developed using the finite element method in 2D. The simulations carried out with this calculation programme we allowedto study the evolution of the hysteresis loop according to the temperature. They also make it possible to deduce the evolution from the losses by hysteresis and eddy currents as a function of temperature.

Design and Study of Magnetization Characteristics of a Magnetostrictive (Tb_0.3Dy_0.7Fe_1.95) Actuator under Zero Pre-Stress Conditions for Direct Current Input

“…Simplified 2-D formulation to investigate transient phenomenon of a current transformer [13], magnetization characteristics and excitation current of single phase transformer in Matlab under dc bias field [14] has been presented using J-A model. Magnetic hysteresis in terms of saturation induction, remanent induction, coercive field and the evaluation of hysteresis as a function of temperature [15] and static and dynamic major B-H loops to study the behaviour of a current transformer focusing on thermal stress on magnetic materials under Curie temperature [16] have been computed by Jiles-Atherton model. From the literature it is showed that the large strain and force output of magnetostrictive material commercially known as Terfenol-D has led numerous researchers to spotlight on its uses for various applications more importantly in automotive applications such as in clutch and brakes.…”
