Determination of faults in 3–Ø Induction Motor By Motor Current Signature Analysis

Induction machine is horse power equipment for industry. It is widely used as drive of many industrial processes but their unexpected failure can cause heavy production loss. Motor current signature analysis (MCSA) is monitoring a parameter of condition in machinery viz the instantaneous current which contain all frequency contain for identification of characteristic fault signature at early stage for avoiding unexpected failure like rotor defect (fragments of rotor bar), stator fault and air-gap peculiar fault. This paper present detailed analysis of how fault frequency is inducing as byproduct of unique rotating flux components and how fault frequency is modulated in stator current which was not done so far. The MCSA Simulation is done by using MATLAB R2017a/Simulink.
