Abstract :
The saturation of the ferromagnetic core in electrical machines significantly affects their performance. In the steady-state and dynamic analyses of electrical machines, an accurate representation of the saturation characteristics in the machine simulation model is important. In this paper, a new trigonometric algorithm has been developed to represent the saturation characteristics of electrical machines, based on the measured saturation characteristics data points. This model can be applied to various kinds and sizes of electrical machines. The results demonstrate the effectiveness of the proposed model to fit the measured data points to a trigonometric functional curve. This model can be incorporated into any kind of electrical machine simulator in order to predict the machine behavior more accurately.
