Convention presentation

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.

Can you repair energy-efficient motors? Maybe.

Most plant engineers and maintenance staff can attest to the reliability of standard-efficiency motors that have been repaired or rewound using industry best practices. They also know repair can cost far less than replacement, especially when the motor has special features. Despite this, some of them hesitate to have failed energy-efficient motors (NEMA Premium models, in particular) repaired because they’ve heard it degrades efficiency.

So, what’s the right answer? Is the decision to repair, rewind or replace a failed energy-efficient motor as simple and straightforward as you may have heard?

Booklet

El Efecto de la Reparación/Rebobinado en la Eficiencia del Motor: Estudio de rebobinado realizado por  EASA/AEMT y la Guía de Buenas Prácticas, ilustran que cuando la reparación/rebobinado de un motor eléctrico se realiza de forma correcta,  no se degrada su eficiencia! y que esta  tampoco se reduce después de varios reparaciones/rebobinados. Basado en un estudio realizado en conjunto por  EASA y la Association of Electrical and Mechanical Trades (AEMT) del Reino Unido, esta publicación concluye que empleando las mejores prácticas de reparación/rebobinado la eficiencia del motor se conserva. Además de una Síntesis, el informe proporciona todos los datos de prueba, mucha información relacionada con procedimientos de prueba y metodología, información de los procedimientos que utilizan buenas prácticas, lecturas complementarias y un capítulo entero sobre las consideraciones para reparar/reemplazar un motor.
