Anomalies in operation of the motor modify harmonic content of motor supply current. Motor electrical current signature analysis (MCSA) is sensing an electrical signal containing current components. In this work, by introducing progressive failures to a healthy motor, we investigated the efficacy of combining motor current signature analysis with vibration-monitoring techniques for the detection of broken bars in the squirrel-cage rotors of three-phase high-efficiency induction motors, which are the new standard in Brazilian industry. Our results demonstrate that the combined approach improves reliability in the diagnosis of broken bars.
