Accurate analysis of magnetic devices with anisotropic vector hysteresis

This paper deals with the implementation of an anisotropic vector Preisach model. as proposed by Mayergoyz, and its insertion into a numerical magneti c field solver. A detailed description of the identification procedure of t he model is presented. Results obtained on some materials where rotational measurements were available are reported. A good agreement is found between simulated and experimental results. Afterwards, the field formulation and the nonlinearity handling scheme of the finite element magnetic solver are outlined and an example on a test case is discussed.:(C) 2000 Elsevier Scie nce B.V.
