A simple method for the parameter identification of the Jiles-Atherton model using only symmetric hysteresis loops

This manuscript describes the identification process of the parameters of the Jiles-Atherton-model (JAM) which can be used to characterize the magnetic behavior of electrical steel sheets. A simple semi-analytic parameter identification process using only a small set of symmetrical hysteresis loops is proposed, which requires low computational effort in contrast to the intensive numerical optimization algorithms which are normally used to gain the JAM parameters. Finally some aspects concerning the representation of minor loops will be discussed.
