Choosing an appropriate lead wire for a new stator winding is an important task. The manufacturer’s information is not always available, or the number of circuits or external connection may have been changed, requiring a redesign of the lead wire.  

Assessment of winding condition prior to, during, and following repairs relies on a series of electrical tests. This webinar recording describes four of the most common electrical tests, explains how to conduct them and assess their outcome.

Overall vibration amplitude levels will indicate if a machine has a problem but determining what that problem could be requires both amplitude and frequency data.  The vibration spectrum provides the most convenient way to analyze those two key vibration parameters. 

This webinar describes the best practice for fitting sleeve bearings in an electric motor. 

This webinar covers what shaft voltage is, what can cause it and what damage it can do to the motor driven system.

This discussion highlights EASA’s overview guide on remote condition monitoring and answers questions from members on the booklet and, and remote condition monitoring in general.

Para monitorear la temperatura de los bobinados y en los rodamientos se pueden usar diferentes tipos de dispositivos. La correcta identificación de los mismos es importante para determinar el tipo de  sensor en casos en los que el dispositivo es desconocido o para escoger el dispositivo correcto para una determinada aplicación.

The open stator impedance test (a.k.a, ball test or dummy rotor test) is used by many service centers as a quality control check before winding treatment and/or a troubleshooting test. This webinar recording reviews test procedures, expected outcomes and incorporating thermal camera imaging.

Explore key mechanical factors when converting a horizontal motor to vertical orientation.

There are heat methods and press methods for straightening shafts. This webinar reviews those methods, their pros and cons, and when one method or another may be applicable.
