Often when we are dealing with three-phase squirrel cage motors we ask ourselves “Is there a standard or a rule of thumb for this motor characteristic?” The 10 characteristics that follow apply to conditions associated with motor starting as well as steady state operation. Examples are provided for each of the characteristics.

We all need friends, right? Isn’t the world a better place when you have someone to share it with? Electric motor shop leaders are no different. Peer groups have long been known as a means by which to advance collective goals and performance. EASA’s Roving Chief Executive (RCE) groups are exactly that - tailored to the executive, owner or general manager of electromechanical repair facilities.

A menudo, cuando trabajamos con motores trifásicos jaula de ardilla, nos preguntamos: "¿Existe una norma o regla general para esta característica del motor?". Las siguientes 10 características aplican tanto al arranque del motor como al funcionamiento en estado estacionario.

This presentation covers induction motor basics for squirrel-cage and wound rotor motors.

There is now a much-needed DC repair standard, created through the participation of EASA members and industry motor users.

Existe ahora una norma para las reparaciones de CC muy necesaria, creada gracias a la participación de miembros de EASA y usuarios de motores de la industria.

When repairing electrical apparatus of any type, a common task is to ensure that machined fits are within acceptable limits of Geometric Dimensioning and Tolerancing (GD&T). The complexity of the task, of course, adds time, and time is never in surplus at a motor service center. Skipping these GD&T checks to save time can lead to mistakes and failures, with costs ranging from a few days of additional work to complete motor replacement and possibly lost production time for both the customer and the service center.

Al reparar aparatos eléctricos de cualquier tipo, una tarea común consiste en asegurar que los ajustes mecanizados se encuentren dentro de los límites aceptables del Dimensionamiento y Tolerancia Geométrica (GD&T).  La complejidad de la tarea, por supuesto, implica tiempo adicional, y el tiempo nunca sobra en un taller mecánico. Omitir estas comprobaciones GD&T para ahorrar tiempo puede provocar errores y fallos, con costos que van desde unos pocos días adicionales de trabajo hasta completar el reemplazo del motor y la posible pérdida de tiempo de producción tanto para el cliente como para el taller.

This recording provides an overview of common different thrust bearing arrangements, with end play guidance tips for each.

Concentric to lap winding conversions are common practice in many EASA service centers. For most stators, this change is feasible and can be made with little difficulty. In some cases, however, it can be quite challenging and result in undesired outcomes due to reduction in copper or insulation.
