ABSTRACT
Vibration analysis is one of the most efficient techniques
used for condition monitoring of the rotating machines. The aim of this report is
to show that the vibration analysis is one of the very efficient and convenient
method for detecting mechanical and electromagnetic problems or faults in the induction
motors. Most of the common faults are bearing failure, winding damage, voltage
waveform distortion, mechanical disproportion, structural resonance and footing
problems, and combinations of mechanical and electrical problems or any other
combination. A short theoretical evaluation of electromagnetic excitation
forces based on classical electrical equipment principle is shown. A comparison
of the advantages and disadvantages of the varied modern techniques used or
recommended now a day in the industry for electrical motor condition monitoring.
In this work, vibration investigation of
rolling element bearings, cage, inner race, outer race defects is studied and analyze.
This
paper provides an easy, non-electrical contact approach to come across and
analyze multiple faults in the curler element bearings of three phase induction
motor with the aid of vibration analysis the usage of microelectromechanical
systems (MEMS) accelerometer. The frequency estimation of motor vibration
because of bearing fault has been finished through speedy Fourier transform set
of rules. the arrival of fault frequencies in vibration spectrum will suggest
more than one faults inside the bearings and more over the lifestyles of
aspect-band frequency additives around important frequency factor indicates air
hole modulation due to bearing fault.
