Abstract :The aim of this paper is to analyze theoretically and experimentally the stator current of an induction machine operating with mixed faults: broken rotor bars and dynamic eccentricity insert ignore into journalissuearticles values(DE);. An analytical explanation of the generation mechanism of all frequencies related to the simultaneous presence of these two defects is given. It is demonstrated that DE diagnosis is very difficult if only stator current analysis is used. Experimental results have been presented to validate the analytical and simulation results.
