Abstract :
In this paper the use of the Preisach model in magnetodynamic field computations is discussed. The discussion is restricted to soft magnetic laminations of silicon iron. For some materials the hysteresis effects vary considerably with the frequency. Therefore, a generalised, rate-dependent Preisach model is adopted. A method is presented that allows the computation of the magnetodynamic fields inside the laminations in presence of this model. The results of these computations show a remarkable agreement with the measurements
