Abstract
When designing electrical devices, it is necessary to take into account the losses from the rotating magnetic field, since they can constitute a significant proportion of losses in the magnetic circuit. This paper describes in detail the model and algorithm of vector 3D magnetic hysteresis based on the scalar Jiles-Atherton model, which uses five parameters. The generalized model of rotating field for isotropic and anisotropic materials is proposed for the direct problem (current-mode control). This model can also be used for 2D magnetic hysteresis. In the same way, a model and algorithm for the inverse problem (voltage control) can be constructed. To plot the vector magnetic hysteresis, the authors use the Maergoiz approach with summation of vector changes in each particular direction. The magnetic hysteresis calculation results in the volume of anisotropic material are shown.
