Misalignment fault detection by wavelet analysis of vibration signals

Abstract: Article history:Asynchronous motors are frequently used in many industrial applications, especially pumps and fans. Placement, bearing and coupling faults are common faults in these types of engines. Misalignment error is a common type of error that is seen very often among these errors. This error may cause efficiency decrease in a short run and vibration may cause short circuit and wear in moving parts in the stator windings in a long run. Early diagnosis of such faults is important in terms of machine healt… Show more

“…The application of wavelet transform can be employed to address the challenge of eliminating noise arising from abrupt changes in very low frequency (VLF) signals utilized in remote sensing, which is particularly crucial for the detection of sub-ionospheric events. In industrial applications, specifically asynchronous motors, misalignment faults, including issues like loose connections and angular imbalances, can be effectively analyzed using Wavelet, transform [7].…”
