Using a Modified Elliot Transfer Function on the Hysteresis G Model Coupled to a 3-D FEM Code

Abstract

In a previous article, the ferromagnetic hysteresis G model was proposed. One of the relevant advantages of the G model is its simplicity compared with classical methods. Here, we present the first steps to insert the model in a 3-D finite-element code. This model uses analytical curves to describe the hysteresis loop. Also, as a contribution, the Elliot transfer function is modified on the way it matches the experimental B(H) curves with good accuracy. Therefore, the main goal here is to investigate its robustness and accuracy when treating the benchmark case Testing Electromagnetic Analysis Methods (TEAM) Problem Number 32. Initially, the G model is presented in a succinct way. Then, the parameter characterization of the modified Elliot transfer function is explained and discussed. This modified Elliot function, coupled with a 3-D FE code, is compared with a similar implementation using the Jiles-Atherton method and experimental data.
