Abstract

In this paper a comparison between static and dynamic formulations of the Jiles-Atherton (JA) hysteresis model is presented. An assessment on the accuracy of core loss prediction and hysteretic loops reproduction of experimentally characterized on stator cores is performed. The novelty in this work is found in the optimized JA parameter datasets describing all the hysteresis loop measured for each of the considered excitation frequencies ranging between 25 and 800 Hz: BH loops with the same excitation frequency, having different maximum flux density values, are modeled using the same JA parameter set. The dynamic model is then compared to Bertotti’s model, and for laminated steel samples, it is better suited to estimate core losses at a... (More)

In this paper a comparison between static and dynamic formulations of the Jiles-Atherton (JA) hysteresis model is presented. An assessment on the accuracy of core loss prediction and hysteretic loops reproduction of experimentally characterized on stator cores is performed. The novelty in this work is found in the optimized JA parameter datasets describing all the hysteresis loop measured for each of the considered excitation frequencies ranging between 25 and 800 Hz: BH loops with the same excitation frequency, having different maximum flux density values, are modeled using the same JA parameter set. The dynamic model is then compared to Bertotti’s model, and for laminated steel samples, it is better suited to estimate core losses at a wide range of test points.
