Abstract

In this paper, the computation of the macroscopic fields inside ferromagnetic laminations is discussed. The magnetodynamic model of non oriented steel laminations is coupled with a dynamic Preisach model. The main goal is the comparison of two previous developed numerical procedures for the electromagnetic field analysis by considering alternating flux excitations containing higher order harmonics. It is shown that a very good agreement is obtained between the measured and computed material response with both techniques. Until now, during the comparison, no remarkable drawback was observed for one of the methods
