Identification of the 2D vector Preisach hysteresis model

Abstract

PurposeThe purpose of this paper is to present a Preisach model to simulate the vector hysteresis properties of ferromagnetic materials.Design/methodology/approachThe vector behavior has been studied at low frequency applying a single‐sheet tester with a round‐shaped specimen, and the locus of the magnetic flux density vector has been controlled by a digital measurement system. An inverse vector Preisach hysteresis model has been developed and identified by using the measured data.FindingsFinally, the inverse model has been inserted into a finite element procedure through the combination of the fixed point technique and the reduced magnetic scalar potential formulation. The developed single‐sheet tester measurement system has been simulated. The applicability of the realized measurement system as well as the developed model has been proven by comparing measured and simulated results.Originality/valueThe identification technique is original, based on a previous work of the author.
