Abstract
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. It seems clear that an understanding of these interactions could provide a means for supplemental monitoring of electrical winding integrity as well as information that might be used to discriminate between electrical and mechanical problems. Presented in this paper is an experimental investigation that is applied to thge detection of electrical winding deterioration in synchronous machines through the measurement of mechanical vibration. Results indicate a strong relationship between these parameters and provide the motivation for additional study and a basis for future applications.
