A Survey Paper on FPGA-Based Broken Bar Detection of Induction Motor Using Motor Current Signature Analysis

Manoj B. Pavale | K. J. Amrutkar

Abstract: Preventive maintenance is one of the major concerns in modern industry where failure detection on motors increases the useful life cycle on the machinery. Broken rotor bars are among the most common failures in induction motors. Differentmethodologies based on current and vibration monitoring have been proposed using FFT and wavelet analysis for preventive monitoring of induction motors resulting in countless techniques for diagnosing specific faults, arising the necessity for a generalized technique that allows multiple fault detection. The paper is focused on the so-called motor current signature analysis (MCSA) which utilizes the results of spectral analysis of the stator current. MCSA techniques include parametric and nonparametric spectrum analysis methods of motor current in general. The novelty of this paper is the tutorial overview of an automatic online diagnosis algorithm for broken-rotor-bar detection, optimized for single low-cost field-programmable gate-array (FPGA) implementation, which guarantees the development of economical self-operated equipment.
