This paper proposes a vector extension of the Loss Surface model for numerically modelling 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 2D finite element code. To handle the non linear problem solved with the Newton-Raphson 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.
