Vector magnetic hysteresis: <i>3D</i>-models and algorithms in direct and reverse statement
When designing electrical devices, it is necessary to take into account the losses from the process of magnetization of the material, since they can constitute a significant proportion of the total losses in the magnetic circuit.In this paper we consider a model and algorithm of vector 3D magnetic hysteresis based on a scalar Jiles-Atherton model using five parameters. A generalized rotating field model for isotropic and anisotropic materials for direct and inverse problems is proposed. The Maergoiz approach is used to construct a vector magnetic hysteresis, which is characterized by summation of vector changes in each specific direction. Examples of modeling of magnetic hysteresis in vector formulation in the volume of anisotropic material are given. The model can be used in the case of two-dimensional (2D) formulation. The simulation results confirm the adequacy of the proposed models.
