Abstract :
This paper presents a model for calculating the hysteresis loss in electrical machines. The model can achieve accurate and computationally efficient hysteresis loss calculations by utilizing both analytical equations and the Energetic hysteresis model. The model results are experimentally verified by comparing to a series of minor hysteresis loop measurements. The hybrid model is then implemented to calculate the core losses in a switched reluctance machine using finite-element simulation. The results show that precise machine core loss prediction requires having a model that is capable of calculating the hysteresis losses under a variety of minor hysteresis loops.
