Bearings represent the most important part in rotating machinery. For any machine problems bearing suffers the consequences. It is therefore necessarily to monitor and diagnose the bearing health condition in order to avoid serious problems that can lead to catastrophic machine failure. Various condition monitoring techniques are used for detection of rotating machine faults. This paper demonstrates...
This paper proposes a new approach to detect insitu bearing faults via stator current monitoring. For insitu bearing faults, the characteristic bearing fault frequencies may not exist, particularly at an early stage. In addition, the bearing fault signatures are usually subtle compared to the dominant components in the sampled stator current. Therefore, in this paper, a noise cancellation technique...
