In 2003, EASA and AEMT (Association of Electrical and Mechanical Trades in the UK) issued a report that proved rewinding motors in accordance with prescribed good practices would maintain efficiency and reliability. But in recent years, claims abounded that premium efficient motors could not be rewound without degrading efficiency. This recording discusses the latest EASA/AEMT research that included independent, third-party testing.

This webinar recording looks at several aspects of winding design to prevent increased temperature rise and decreased efficiency.

Is the motor drawing high no-load amps and winding data are correct? Are you experiencing unusual heating of the stator under load? Those common questions can be answered by checking the stator core condition.

¿El motor consume mucha corriente en vacío, aunque los datos del bobinado son correctos? ¿El motor se calienta con carga de forma inusual? Estas son preguntas comunes que pueden ser resueltas verificando la condición del núcleo del estator. En este webinario discutiremos cómo realizar la prueba de lazo en el núcleo de un estator y cómo analizar los resultados obtenidos, proporcionando información sobre los equipos utilizados, consejos para reparar el núcleo del estator y otras pruebas alternativas.

This manual covers horizontal and vertical squirrel-cage induction motors in the 300 to 5,000 horsepower range, low- and medium-voltage. Most of the principles covered apply to other sizes as well. This manual focuses primarily on IEC motors and standards.

En este artículo discutiremos las pruebas de los condensadores usados en los motores eléctricos en general, así como también las pruebas asociadas al uso específico de condensadores empleados para la corrección del factor de potencia y en el arranque de los motores eléctricos.

In March of 2019, EASA conducted an in-depth survey to better understand how end users decide between repairing or replacing electric motors and to identify electric motor repair/replacement trends. Internet-enabled condition monitoring has been a hot topic recently and, as a result, questions related to this were added to the list of survey questions. The survey returned some very interesting results about internet-enabled condition monitoring.
