Abstract

This paper presents a hysteresis model for electromagnetic sensors and actuators, which are composed of ferromagnetic materials. The model is based on the Preisach operator, which is capable to fully describe major as well as minor hysteresis loops. To obtain the appropriate measured data for fitting the Preisach operator, we have developed an Epstein setup according to IEC 60404-2. This work also describes the use of the Lorentzian function as a possible candidate for the accurate approximation of the Preisach density function in the modeling of scalar hysteresis for nonoriented grain steels. In particular, we discuss here the identification procedure of the Preisach weighting functions from measured data.
