Anisotropic Models of Nonlinear Magnetic Behavior Laws for Finite Element Modeling of Iron Losses in a Toroidal Core
Résumé
This paper explores the implications of nonlinear anisotropic behavior models on the simulation of magnetic losses in a toroidal core made of a conventional Grain-Oriented Electrical Steel (GOES) within a finite element method (FEM) simulation environment. GO laminations are commonly used to improve the efficiency of electrical machines, but their complex behavior requires accurate modeling. Nonlinear resolutions for different anisotropy models were implemented and compared with a measurement-based model. Then, an anisotropic iron loss model from Appino et al. has been applied to evaluate the iron losses. This method provides a decisive way to qualitatively assess various models directly, relying on measurable quantities of interest.
