Condition Monitoring and Fault Diagnosis of Induction Motor - An Experimental Analysis

Abstract

Continuous work of Induction Motor (IM) is an exigency for the recent industries which without a doubt influences the reliability and stability of the production process. Detecting the faults at an early stage can reduce the loss in time and expenses related to sudden stop of the motor. Consequently, condition monitoring is considered the first proposition in this domain to detect the initial faults in the machine. In this paper, we detail the most frequent failures in the IM and the condition monitoring techniques used to detect these faults. Furthermore, experimental tests are done on many common external faults of IM, and a comprehensive comparative study among more than 10 faults is done for a better comprehension of the machine behavior during the faults.
