DYNAMIC PREISACH MODELING OF FERROMAGNETIC UNDER DISTORTED FLUX EXCITATIONS

In this paper, the computation of the macroscopic fields inside ferrom agnetic laminations is discussed. The magnetodynamic model of non orie nted steel laminations is coupled with a dynamic Preisach model. The m ain goal is the comparison of two previous developed numerical procedu res 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 mat erial response with both techniques. Uptill now, during the comparison , no remarkable drawback was observed for one of the methods.
