Determining the Induction Motor Degradation State Based on Rundown Characteristics

This paper proposes the criteria for estimating the operational condition of an induction motor, determining a degree of its degradation wear, and predicting a failure-free operation and the emergency failure instance based on the rundown parameters after the power supply voltage is disconnected.

Description
Summary:This paper proposes the criteria for estimating the operational condition of an induction motor, determining a degree of its degradation wear, and predicting a failure-free operation and the emergency failure instance based on the rundown parameters after the power supply voltage is disconnected. The results of studying the possibility of using the induction motor rundown regime for diagnosing the degradation changes during operation are presented. A probabilistic statistical analysis of reliability and accuracy of the predicted parameters was performed, and the calculation equations for estimating the levels of measurement and predictions errors are provided.
