Broken bars and/or end rings detection in three-phase induction motors by the extended Park's vector approach

摘要

In this paper, we present a method dedicated to the detection of broken bars and end-rings defects in a three-phase induction motor. This method is based on the spectral analysis of the stator current Park's vector modulus. The theoretical principles of this method are described. Simulation and experimental results demonstrate the effectiveness of this method for the detection of the squirrel cage faults.
