Diagnosis of mechanical unbalance for double cage induction motor load in time-varying conditions based on motor vibration signature analysis

Abstract: This paper investigates the detectability of mechanical unbalance in double cage induction motor load using motor vibration signature analysis technique. Rotor imbalances induce specific harmonic components in electrical, electromagnetical, and mechanical quantities. Harmonic components characteristic of this category of rotor faults, issued from vibration signals analysis, are closely related to rotating speed of the rotor, which complicates its detection under non-stationary operating conditions of the motor… Show more

“…In addition, detection of faults at the early stages gives a lot of advantages like reliability of operation, increased motor life and economic benefits [1]. When motor starts becoming faulty it tends to change some of its parameters, such as mechanical vibrations [4], [5], electromagnetic field distributions [6], [7], temperature [8], stator's current [9]- [11]. Since induction motors are proportionally among the biggest energy consumers worldwide, their proper maintenance and early fault diagnostics will increase efficiency as well.…”

“…These techniques include: Analysis of acoustic emissions [7], [8], oil analysis [9], [11] and specifically vibratory analysis. In particular, the investigation of vibratory signals has been proposed in different works, using different approaches: statistical analysis [10]- [11], temporal and/or frequency domain [7], [12], [13].…”
