Diagnosing Wiped Bearing Eccentricity by asdasd is a document available to read on EtoBox.
A motor with an eccentric air gap between the rotor and stator can cause increased vibration, insulation degradation, and potential rubbing due to unbalanced magnetic pull. There are two types of eccentricity: static, caused by a misaligned end bell; and dynamic, caused by a wiped bearing. The Rotor Influence Check tests the inductance of stator windings while rotating the de-energized rotor to detect residual flux and reflected impedance from rotor faults like cracked or broken bars, shown as variations in
