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 providing many methods to confirm some of these serious faults. This presentation will provide examples of many methods of utilizing electric motor testing to identify rotor anomalies and provide confirmation and correlation.
Learn how to differentiate between a good motor, a stator fault, a rotor fault and defective circuitry (PF Caps), utilizing energized and de-energized electric motor testing.
Learn how to confirm rotor bar faults with multiple motor test data sets.
Learn how to identify rotor issues for static and dynamic eccentricity.
Learn how to identify rotor unbalance or misalignment using current signature.
Learn how to identify rotor axial movement using current signature.
About the Presenter
Don came to work for Snell in 2002 to train our thermographers to conduct electric motor testing. He has been all over the world, testing, evaluating and troubleshooting problems with electric motors and motor circuits. He has worked on motors rated in ounce inches of torque all the way up to a NASA wind tunnel synchronous motor that is 80,000 horsepower.
Don’s diverse electrical, electrical/mechanical, electronic, and sound motor knowledge is founded in twenty years of service in the Navy Nuclear Submarine Service. As the Snell Group’s Technology Lead for EMT and Power Quality Analysis, he brings 44 years of knowledge in the operation, maintenance and testing of electric motors and motor circuits. His 20-year exposure to the maintenance environment on US Navy nuclear submarines has provided invaluable insights for our customers’ reliability needs.
