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.

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. 

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

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.

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.

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.

This webinar discusses specific procedures to obtain the best possible results when machining & undercutting commutators for DC machines.

This presentation discusses the importance of tracking rework in the shop and how it can lead to focused training opportunities, improved turnaround times and improved profitability.

This seminar will cover DC machine theory and operation, as well as repair tips. Topics will include testing and winding of armatures, fields, interpoles and compensating windings, machine work, balancing, assembly and final testing. The theory portion is structured so that it can be grasped by entry-level personnel, while the overall material is in-depth enough that those with 30 years of experience or more will benefit.

Las pruebas de Resistencia de Aislamiento, Relación de Absorción Dieléctrica (DAR) e índice de Polarización (IP) son herramientas comúnmente usadas para evaluar la condición del aislamiento de las máquinas eléctricas rotativas y para confirmar la integridad del sistema de aislamiento a tierra, detectando la presencia de humedad que puede ocasionar fallos en los devanados. En las máquinas grandes, un adecuado análisis de tendencias ayuda a detectar cambios importantes y a tomar acciones correctivas antes de que ocurran fallos catastróficos.

EASA Internal Connection Diagrams for Three-Phase Electric Motors is available to members as a free PDF download and contains hundreds of connections, as well as templates for windings up to 30 poles. This webinar recording shows how to access it and provide examples of how to use it.
