Stator Fault Diagnosis of Single Phase Induction Motors Using Fuzzy Logic System

Abstract

Fault diagnosis of electrical machine is gaining particular importance in view of machine down-time and revenue losses to the industry. Therefore, it is always essential to check motor performance from time to time. This paper use the technology of fuzzy logic for detecting and diagnosing the stator faults in single phase induction motor to avoid the damage of the motor. The application of fuzzy logic is simulated using fuzzy logic tool box in MATLAB. The main function of fuzzy logicfault detection consists of two inputs the first for stator current and the second for the rotor speed and one output which is the incipient fault.
