Construction of magnetic hysteresis loops and its applications in parameter identification for hysteresis models

This paper presents an algorithm to construct the major and symmetric minor hysteresis loops based on the normal magnetization curve, the intrinsic coercivity, and optionally the residual flux density. All these input data are normally available from the manufacturers. Some typical hysteresis loops constructed from the magnetization curve are validated by the measured hysteresis loops. Two application examples are presented: 1) to identify the parameters of classic Preisach model based on the constructed hysteresis loops; 2) to identify the parameters of a play model, and then to simulate a hysteresis motor based on the constructed major loop.
