Analysis and diagnosis of the different defects of asynchronous machines by vibration analysis

The electric machines and particularly the asynchronous machines act an important role nowadays in all industrial applications. To assure the availability and the safety of working of these is a fundamental job. It is therefore necessary to develop the systems permitting to supervise and to diagnose the state of health of these devices. This article has for object to determine the different anomalies that can harm the good working of an electric motor.
