The aim of this paper is to evaluate the detectability of broken rotor bars in induction motors by means of the analysis in the frequency domain of three quantities (stator current, external stray flux and vibration) measured in steady state condition, at different levels of load and with different power supplies. The effects of the spectral leakage and of the harmonics arising from the inverters are assessed in the observation of the fault-associated harmonics.

Abstract

The aim of this paper is to evaluate the detectability of broken rotor bars in induction motors by means of the analysis in the frequency domain of three quantities (stator current, external stray flux and vibration) measured in steady state condition, at different levels of load and with different power supplies. The effects of the spectral leakage and of the harmonics arising from the inverters are assessed in the observation of the fault-associated harmonics.
