Este webinario cubrirá los fallos asociados con los motores trifásicos accionados con variadores electrónicos de frecuencia (VFDs) y como rebobinarlos, rebajando las posibilidades de fallos futuros.

Knowing how to interact with Eddy can dramatically improve your results with technical questions, troubleshooting and documentation resources.

This presentation covers induction motor basics for squirrel-cage and wound rotor motors.

This recording provides an overview of common different thrust bearing arrangements, with end play guidance tips for each.

Escoger el cable adecuado para el bobinado de un nuevo estator es una tarea crítica cuando no existen especificaciones del fabricante, el número circuitos o las conexiones externas varíe o se requiera cambiar el cable de salida. 

Manual calculations are tedious, time-consuming and error prone. Several calculators are available to logged-in members at easa.com that can save time and prevent errors. 

The impeller is the primary mass component on most pump rotors. Impeller balancing is an important component of pump repair. Proper balancing procedures will ensure the repaired pump will operate with a minimum of vibration.

This presentation stresses the importance of taking accurate winding data and explains and emphasizes the consequences of inaccurate data. One of the main benefits of this presentation is to improve ability to “get it right the first time” to avoid the added cost and time of another rewind to correct errors.

This webinar goes through some data verification and redesign examples using the Motor Stats view within EASA’s AC Motor Verification & Redesign software to learn what it tells us and what it doesn’t tell us about our data.

Horizontal and vertical motors have uniquely different requirements for endplay, while sleeve bearing machines bring their own challenges. This presentation examines those differences.

This presentation explores the distinction between a controlled environment and a cleanroom, the requirements for both, and provides details to help you determine if you want to add a controlled environment or a cleanroom to your facility.

Todos los miembros de EASA tienen acceso al libro: Diagramas de Conexión Interna de Motores Eléctricos Trifásicos que se puede descargar gratuitamente en easa.com.

Este libro contiene cientos de conexiones y plantillas de los devanados trifásicos más comunes de hasta 30 polos. Durante este seminario web proporcionamos ejemplos de diferentes tipos de conexiones.

This presentation reviews procedures that explain how to identify unmarked leads of three-phase motors with one or two windings.

This presentation focusses on critical close fit tolerances and certain surface finish specifications.

When a core loss test reveals localized hot spots, or visual inspection identifies physical damage, the ability to repair the damage in a cost-effective manner means the difference between repair or replacement.

This presentation provides a high-level overview of the program and is intended for anyone wanting to learn more about the ERT program. 

Este webinario incluye procedimientos de prueba, resultados esperados y el uso de cámaras termográficas para determinar posibles problemas en las conexiones o en las soldaduras.

Learn how to effectively use EASA's live, ever-expanding online database of more than 250,000 windings.

This focused introduction will explain the what, how and why of static-couple balancing from a practical point of view.

Are you encountering high no-load current or high current with load? This presentation will look into the causes and cures.

When preparing to rewind random or form-wound status, sometimes there just doesn’t seem to be enough room in the stator slot for the desired conductor area and insulation quantities. This presentation looks at balancing stator copper losses against insulation reliability.

When repairing centrifugal and axial flow pumps, axial thrust is a concern. An understanding of the causes and the mitigating provisions of various pump designs will help repair technicians to ensure those provisions work properly.

This presentation addresses many of the most common safety hazards and situations that face service centers.

¿Recibió un motor antiguo bobinado con alambre de aluminio? Este webinario explicará como realizar la conversión adecuada de alambre de aluminio a alambre de cobre en máquinas de CA y CC, incluyendo ejemplos para el rebobinado de estatores y campos shunt.

Variable frequency drives (VFDs) are more common than ever before.  Sometimes when a VFD is introduced into a motor driven system, system reliability suffers. This recording addresses some of the common factors that reduce motor driven system reliability and how to correct them.   

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.  

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.

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.
