Diagnosis and Comparison between Stator Current Analysis and Vibration Analysis of Static Eccentricity Faults in The Induction Motor

This paper presents two diagnosis techniques currently very much answered by the analysis of the signature of the stator current and the analysis of vibration signal because they are primarily. These techniques are based on the motor current signature analysis (MCSA). The MCSA method was based on analyzing the Fast Fourier Transform (FFT) of the stator current to analyze the spectral content of the different signals. The precision of these techniques depends on the load and speed of the induction machine. The diagnosis and detection of the presence of static eccentricity faults by various techniques mentioned above, and it was performed analytically and practically. The purpose of this article is to compare two methods: analysis of the stator current (MCSA-FFT) and the vibration analysis method (MVSA-FFT) to access a valuable decision.
