Some practical aspects of eccentricity detection in induction motors for different supply conditions
In this paper, we advance results of an ongoing investigation related with the detection of static and dynamic eccentricity in cage induction motors fed by frequency converter using line current spectral analysis. A statistical analysis of the results obtained with the laboratory motors for different supply conditions has been carried out. These results allow us to present some preliminary conclusions.
