The vibration monitoring techniques helps to effectively diagnose mechanical faults such as bearing defect and stator rotor rub. These defects cause changes in the vibration signature over time. Bearing, the most vulnerable to failure due to continuous working under fatigue loading leads to defects. Vibration is a manifestation of induction motor due to the issues in alignment, balancing, and clearances.
The breakdown of the induction motor would not be affordable due to remarkable financial loss, unpredicted shutdown, and the associated repair cost. Hence, it is necessary to monitor its condition to avoid any catastrophic failure and stoppage of production. It is a very important driving unit of the machine. Almost in every industry, around 90% of the machines apply an induction motor as a prime mover. An induction motor is at the heart of every rotating machine and hence it is a very vital component.
