Induction Motor Broken Rotor Bar Fault
Vibration analysis reveals sidebands around the supply frequency, indicating a broken rotor bar fault in an induction motor. Early detection through vibration analysis enables scheduled maintenance and maximizes asset lifespan.
Broken Rotor Bar Detection through Vibration Analysis
In this video, we present vibration data highlighting the signature indicators of a broken rotor bar fault in an induction motor. Notice the telltale sidebands around the supply frequency (often at 2× slip frequency), a classic pattern of electrical asymmetry. These patterns are often faint — but through expert signal analysis and condition monitoring, they become clear warnings.
💡 Why it matters:
A broken rotor bar can lead to overheating, imbalance, torque ripple, and eventual motor failure. Early detection through vibration analysis allows for scheduled maintenance, reduced downtime, and maximized asset lifespan.
