Preisach-type hysteresis models in magnetic field computation

The paper illustrates the evolution of Preisach-type models of hysteresis, involving mean field effect, dynamic effect and vector behaviour and their capability to be included into finite element electromagnetic field computa tion. The study makes reference to 1D and 2D formulations developed under d ifferent simplifying assumptions. Particular attention is devoted to the us e of fixed point technique which is found to be very advantageous for the s olution of hysteretic problems. Some examples of the analysis of magnetic f ield problems with hysteresis are finally presented. (C) 2000 Elsevier Scie nce B.V. All rights reserved.
