Multiple fault detection through information entropy analysis in ASD-fed induction motors
In this work broken rotor bars, misalignment, and unbalance are detected in induction motors powered by an adjustable speed drive (ASD) using the supply electric current information contents. The proposed methodology is implemented in a field programmable gate array offering a low-cost and portable solution for induction motor monitoring in real time. Results show that the introduced approach provides high detectability of treated faults at different rotational speed (30 Hz, 40 Hz, and 50 Hz) making it suitable for reliable online and continuous monitoring of the operational condition since control of the induction motor rotating speed through an ASD is a common practice in industry. © 2011 IEEE.
