Abstract

This paper proposes the measurement of Instantaneous An- gular Speed (IAS) as a condition monitoring tool for Induction Motors. The main advantages with respect to vibration and Motor Current Signa- ture Analysis (MCSA) are the high resolution of the result obtained com- bined with small data storage. The hi-quality information shows many hi-order harmonics that are not easy to interprete and correlate with the machine construction. In this paper a review of the analytic charac- teristics frequencies due to electromagnetic effects is reported and, fur- thermore, theoretical results and experiments are compared. From the comparison obtained, the authors conclude that IAS has the potential of extract information due to the rotor’s skewness.
