For the wide variety of DC motor applications, there are those where a straight shunt motor is preferred and others which seem to require the greater starting torque of a series field. Why are there different field designs and are they interchangeable? What about the nameplates marked “stab shunt” or “str shunt?” The purpose of this article is to clear up lingering confusion about the types of fields as well as the benefits of each.
Para la amplia variedad de aplicaciones de motores de CC, existen aquellas en las que se prefiere un motor shunt directo (straight shunt) y otras que parece que necesitan el mayor torque de arranque de un campo serie. ¿Por qué existen diferentes diseños de campo y son intercambiables? ¿Qué sucede con las placas de datos marcadas como “stab shunt” o “str shunt?” El propósito de este artículo es aclarar la confusión permanente sobre los tipos de campos, como también los beneficios de cada uno.
Process downtime is expensive—even more so when it’s unexpected. So, when an electric motor fails, we tend to pull, repair, or replace it, and move on as quickly as possible. In doing so, however, we may miss an opportunity to capture basic information that could help improve the reliability of the application. With a little planning, these data can be gathered with no delay in startup.
The case study in this article demonstrates that EASA members have great opportunities to develop and improve customer relationships by helping them solve their application problems.
This 40-page booklet provides great advice for obtaining the longest, most efficient and cost-effective operation from general and definite purpose electric motors.
