Vibration and motor current analysis of induction motors ...

Electric motors play an important role in industry, and the induction motors are the most widely used among them. Any motor failure interrupts the process, causes loss of productivity, and may also damages to other machinery. Therefore, to prevent sudden failure of motor (such as on the large or critical motor) it is essential to have an early fault detection mechanism.
