摘要:
This article proposes a vector extension of the Loss Surface (LS) model for numerically modeling hysteretic phenomena in electromagnetic device simulations with isotropic ferromagnetic materials. The vectorization strategy is based on Mayergoyz's approach. The developed model has been implemented in the 2-D finite-element code. To handle the nonlinear problem solved with the Newton-Raphson (NR) algorithm, a suitable method is proposed for the approximation of the reluctivity tensor. Several test cases from TEAM problem 32 were investigated for validation. The results are in good agreement with measurements combining accuracy and short computation times.
