Implementation of an Anisotropic Magnetic Model Based on the Effective Field in a Finite Element Model

The magnetic anisotropic of steel sheets tends to increase the core losses and the magnetizing current of electric machines. Their accurate evaluation can adjust the machine design to improve the machine performances. Whereas various non-linear magnetic anisotropic models can represent the material behavior properly, their implementation into finite element requires the magnetic model to be derived from a thermodynamic potential. In this article, we implement the anisotropic model based on the effective field into a finite element model.
