Motor Current Signal Analysis for Diagnosis of Fault Conditions in Shipboard Equipment

Abstract

Motor Current Signal Analysis is a technique for diagnosing problems in mechanical equipment by monitoring nothing more than the input electrical signal. The induction motor acts as a bilateral transducer, converting mechanical vibrations into electrical signal perturbations. It provides a method for a non-invasive testing of mechanical systems. The objective of this project was to develop the signal processing routines and classification techniques necessary to implement this method of fault detection. Data were collected from a Byron Jackson Main Sea Water Pump found on a U.S. submarine. The fault that was monitored was an eroded impeller condition. This project not only provides a method for detecting this specific fault condition, but furnishes the groundwork for the development of test equipment to completely monitor the pump's operation.
