A 2D FINITE-ELEMENT PROCEDURE FOR MAGNETIC ANALYSIS INVOLVING NONLINEAR AND HYSTERETIC MATERIALS

In this paper a 21) Finite Element procedure devised to handle both soft magnetic materials and hysteretic ones, on the basis of Preisach's classical approach for scalar and vector hysteresis, is presented. In the scalar case, a model identified by a reduced set of experimental data is proposed, whereas for the vector case a more demanding identification procedure is required. The resulting modular ''Preisach engines'' are used to solve some problems of practical engineering type.
