Abstract

This paper presents a new strategy for modeling the saturated induction machine. Saturation is considered by means of "magnetic harmonic functions," defined in the model and obtained experimentally, considering the fundamental and third harmonic of the spatial flux density distribution. It is shown that the distortions on voltage and current waveforms are due to harmonic content in the main flux, caused by saturation. Experimental and theoretical results for a capacitor self-excited induction generator are presented to show the validity of the proposed model
