Abstract: Rolling element bearings are critical components in induction motors and monitoring their condition is important to avoid failures. Several condition monitoring techniques for the bearings are available. Out of these, stator current monitoring is a relatively new technique. Vibration, stator current, acoustic emission and shock pulse methods (SPMs) and FEM, surface analysis, for the detection of a defect in the Inner race of induction motor ball bearing have been compared. The measurements were performed at different loads and different speeds. The defect in the bearing could be detected by all the methods.
