BEARING FAULT DETECTION IN INDUCTION MOTOR USING MOTOR CURRENT SIGNATURE ANALYSIS
The health condition of induction motor can be effectively monitored using a non-intrusive method called Motor Current Signature Analysis (MCSA). The concept is to treat the electric motor as an implicit transducer built into motor-driven equipment; the current behaviour can thus be used to show various health conditions of the motor as well as the load it is driving. The objective of this work is to explore the feasibility of MCSA for continuous monitoring and diagnostic purposes. For signal processing we use Fast Fourier Transform. In summary, the findings show promising results which could lead to better reliability performance of the induction motor and lower maintenance costs.
