Performance curves are among the most crucial and frequently requested documents from fan manufacturers, second only to dimensional prints. While many request these documents, not everyone fully understands their significance or maximizes their potential.
Las curvas de rendimiento se encuentran entre los documentos más importantes y solicitados a los fabricantes de ventiladores, superadas únicamente por los planos dimensionales. Si bien muchos solicitan esta documentación, no todos comprenden plenamente su importancia ni aprovechan al máximo su potencial.
Few things are less exciting in the motor world than a large synchronous motor that refuses to start—and all too often, the root cause is excitation. This article provides an overview of what synchronous motor excitation is, how it works, and the common issues you are likely to encounter.
Pocas cosas resultan menos estimulantes en el mundo de los motores que un gran motor sincrónico que se niega a arrancar; y, con demasiada frecuencia, la causa raíz reside en la excitación. Este artículo ofrece un panorama general de qué es la excitación de un motor síncrono, cómo funciona y los problemas habituales que es probable que encuentre.
