MCSA BASED MECHANICAL FAULT ANALYSIS OF THREE PHASE SQUIRREL CAGE INDUCTION MOTOR
Metadata[+] Show full item record
This paper deals with mechanical fault analysis of three phase induction motor using Motor Current Signature Analysis. This is a reliable technique that can be used to monitor the health of three phase induction motor. Three phase induction motor is used to find the Current Signature before and after the fault occurs. The FFT of Current signal is analyzed using Advanced Signal processor to find harmonics present before and after the fault occur. This data is used to detect the mechanical faults way before they cause harm to the motor and power system. Ball bearing fault is created practically to find the harmonics components in the current drawn. Most of the practical results match with the theoretical values obtained from the literature.
