Vector extension of the Loss Surface model for modelling static and dynamic hysteresis
Résumé
This paper proposes a vector extension of the Loss Surface model used for modelling static and dynamic hysteresis phenomena that appear in electromagnetic devices containing soft ferromagnetic materials. The aim being to include the behavior of the material during a solving process based on the finite element method (FEM). The vectorization strategy is based on the Mayergoyz approach. The developed model has been implemented in the 2D FEM formulation. The nonlinear problem is solved using the Newton-Raphson algorithm with an exact approximation of the magnetic reluctivity tensor. Several test cases of the TEAM 32 problem have been studied for validation purposes. The results are in agreement with the measurements combining good accuracy and saving of computation time.
