• Description:
  Efforts to apply mechanical vibration technology to the condition monitoring of ac induction motors have generally been focused on areas relating to unbalance, bearing condition, eccentricities, and other mechanical phenomena. However, theory predicts that electrical winding deterioration in these machines will modify internal magnetic forces and that the resulting changes in vibration characteristics should be a useful indicator of winding condition. Presented in this paper is an experimental investigation that is designed to demonstrate the effects of stator winding deterioration on the frequency spectrum of bearing vibration in an induction machine. The data clearly shows specific vibration frequencies that may be associated with this type of electrical malfunction. This information may be used by maintenance personnel who are monitoring bearing vibrations to distinguish between mechanical and electrical problems or to identify electrical winding breakdown.
