IRIS POWER

Detecting Induction Motor Rotor Problems with Motor Current Signature Analysis – Europe

September 30, 2020 2:00 PM CEST Webinar

No charge

Live Webinar with Q&A

Join us on September 30th at 2:00 PM EDT for our latest webinar onDetecting Induction Motor Rotor Problems with Motor Current Signature Analysis given by our industry expert Greg Stone.

 

This webinar will review the design of squirrel cage induction motor rotors, and discuss the manufacturing and aging processes that can lead to rotor winding broken rotor bars, cracked short circuit rings and unsymmetrical magnetic fields. Detection of broken rotor bars by on-line vibration monitoring is briefly discussed, as are off-line tests. Finding rotor winding problems by measuring the stator winding current on one phase (motor current signature analysis or MCSA) is introduced as is the Iris Power MDSP3. Examples of using the MDSP3 for detecting rotor winding problems are presented. Advantages and disadvantages of MCSA are also discussed.

WHO SHOULD JOIN?

The webinar is directed at engineering and maintenance personnel who purchase, test, maintain, and/or repair high voltage rotating machines. Consultants, manufacturers and repair shop personnel are also welcome.

Host Bio:

Dr. Greg Stone was one of the developers of on-line partial discharge test methods to evaluate the condition of the high voltage insulation in stator windings. From 1975 to 1990 he was a Dielectrics Engineer with Ontario Hydro, a large Canadian power generation company. Since 1990, Dr. Stone has been employed at Iris Power L.P. in Toronto Canada, a motor and generator condition monitoring company he helped to form. Iris is now owned by Qualitrol Corp. He has published two books on motor and generator winding maintenance and authored more than 200 papers concerned with rotating machine windings. Since 1980 he has also been active in creating and updating many IEEE and IEC standards. Greg Stone has a PhD in Electrical Engineering, and is a Fellow of the IEEE. He has won numerous awards from the IEC, Cigre and IEEE for his technical contributions.
