Bearing lubrication is very important to ensure a satisfactory and long operation of bearings. An excess of lubrication can be as damaging as a lack of lubrication. An excess of oil or grease has damaging effects in the short term such as difficult heat evacuation, sliding balls and greater current consumption. As MCSA is widely recognized as a useful and reliable tool for condition monitoring of...
The aim of this paper is to investigate the effects of the bearing faults on the stator current and on the efficiency of the induction motors, in order to verify the effectiveness of the analysis of these variables for diagnostic purposes. The paper reports the experimental results on four different types of bearing faults.
