Rotor-bar breakage mechanism and prognosis in an induction motor
2015
© 1982-2012 IEEE. This paper proposes a condition-based maintenance and prognostics and health management (CBM/PHM) procedure for a rotor bar in an induction motor. The methodology is based on the results of a fatigue test intended to reproduce in the most natural way a bar breakage in order to carry out a comparison between transient and stationary diagnosis methods for incipient fault detection. Newly developed techniques in stator-current transient analysis have allowed tracking the developing fault during the last part of the test, identifying the failure mechanism, and establishing a physical model of the process. This nonlinear failure model is integrated in a particle filtering algor…
Experimental study of the evolution of a bar breakage process in a commercial induction machine
2008
This paper analyzes the results of a destructive test developed on a commercial induction motor. The test is designed to reproduce in the laboratory the cage degradation process of an induction motor subjected to a high amount of working cycles, which include heavy startups. During each cycle, the main magnitudes related to the motor condition monitoring are registered, at steady state as well as at transient regime. From these magnitudes, some fault indicators described in the literature are calculated, and so, it is possible to follow their evolution. This analysis assesses the use of such small commercial machines in a test bed as a way of developing a failure that can be used to compare…
