Abstract

This paper presents a novel optimization strategy for fitting the Jiles-Atherton (JA) hysteresis model to experimental stator yoke core loss measurements and locked-rotor IPMSM calculations. The first study aims to identify a single set of JA model parameters that track sample core losses at different magnetization levels at a given frequency: the analytical model is compared with finite element method simulations that include hysteresis modeling and core losses. The challenges of the second calculation are the inclusion of PM in the FEM simulation with the JA model, the torque computation, and the comparison with conventional calculation methods for soft magnetic cores. The FEM calculations have been performed with the Comsol... (More)

This paper presents a novel optimization strategy for fitting the Jiles-Atherton (JA) hysteresis model to experimental stator yoke core loss measurements and locked-rotor IPMSM calculations. The first study aims to identify a single set of JA model parameters that track sample core losses at different magnetization levels at a given frequency: the analytical model is compared with finite element method simulations that include hysteresis modeling and core losses. The challenges of the second calculation are the inclusion of PM in the FEM simulation with the JA model, the torque computation, and the comparison with conventional calculation methods for soft magnetic cores. The FEM calculations have been performed with the Comsol multiphysics, which allows the use of the JA model.
