Rotor Bar Fault Maintenance Issue: Vibration Sensor Alert

A 398 KW MV motor that runs a blower fan in a cement plant was showing strange behavior. The vibration equipment indicated vibration amplitudes that became chronic with the passage of time. The maintenance team, not knowing what the issue was, ran the motor until the bearings had to be replaced...

Using Motor Current Signature To Detect The Number Of Cracked Rotor Bars In Induction Motors

This presentation will not only focus on collecting current signature , but also will cover the analysis part of spectral data to determine the number of cracked/broken bars along with the severity level and needed corresponding corrective actions . This will be clearly shown through two real case studies in my plant for two 1.2 MW induction motors.
