Finding and confirming rotor problems can be challenging, frustrating and sometimes easy to misdiagnose. Electric motor testing is the optimum technology for identifying rotor problems as well as provide many methods to confirm some of these serious faults. This presentations will provide examples of many methods of utilizing Electric Motor Testing to identify rotor anomalies and provide confirmation and correlation.
1.Learn how to differentiate between a good motor, a stator fault, a rotor fault or defective circuitry (PF Caps), utilizing Energized and De-energized Electric Motor Testing
2.Learn how to confirm rotor bar faults with multiple motor test data sets.
3.Learn how to identify rotor issues for static and dynamic eccentricity.
4.Learn how to identify rotor unbalance or misalignment using current signature.
5.Learn how to identify rotor axial movement using current signature.
