Abstract

This paper proposes a tractable and robust numerical method to predict iron losses in electrical steel laminations that are subjected to high-frequency excitations. To achieve this goal, Preisach modeling and the finite-difference method are first employed to simulate the hysteresis loss and eddy current loss, respectively. With this proposed algorithm, a better approximation of the excess loss and its optimal parameter identification is obtained. The proposed algorithm, when compared with conventional engineering models, reduces the errors between the estimated values and the measured values with tolerable computational burden.
