Diagnosis of bearing fault in induction motor using Bayesian optimization-based ensemble classifier

Electrical equipment plays a vital role in industry. Among various electrical equipment, induction motors are quite commonly used in many industrial applications. One of the most common faults that occurs in induction motors is bearing fault. In this article, bearing fault is diagnosed in an induction motor using vibration signals with the help of a simple Artificial Intelligence (AI)-based model. Because, the vibration signals are not dependent on the motor type, simple to measure, cost effective and yields good results. In the proposed system, accurate prediction of bearing condition is carried out using Bayesian optimization-based ensemble classifier (BOEC). The performance of the BOEC-based bearing fault diagnosis system is compared with other conventional techniques and the comparison results confirm the superior performance of the proposed system. Also, the accuracy obtained from the BOEC-based bearing fault diagnosis system is 99.97%. To verify the effectiveness of the proposed system, a hardware prototype is set up in the laboratory and bearing conditions of various induction motors are analyzed.
