Estimation of Broken Rotor in Induction Machine Using Spectral Analysis of Instantaneous Power

Astrit BARDHI [3] | Alfred PJETRI | Gentian DUME

Abstract: In industry; a pivotal role is played by induction machines resulting in a strong demand for their respective reliable and safe operation. Faults and failures of induction machines can lead to excessive downtimes and generate large losses in terms of maintenance and revenues. Nowadays; experts are performing numerous researches to reduce both unexpected failures and maintenance cost by detecting faults during the machine activity operations. In this matter; measurements and monitoring must be performed during on-line conditions. In order to accurately identify the rotor bars damage; we have used spectral analysis of instantaneous power of induction machine; which are easily monitored. The instantaneous power provides the possibility to detect faults in induction machine. To confirm our theoretical analysis with experimental data; an induction machine was cut three rotor bars. The obtained theoretical and experimental results show coherence among each other.

Keywords: Induction machine, rotor bars damage, instantaneous power, spectral analysis, on line monitoring
