The Effect of Repair/Rewinding on Premium Efficiency/IE3 Motors
This webinar covers the results and the technical details of the recently completed follow-up to the 2003 EASA/AEMT Rewind Study.
Do What You Can To Protect The Investment

Storing an electric motor for more than a few weeks involves several steps to ensure it will operate properly when needed. Factors like temperature, humidity and ambient vibration in the storage area also influence the choice of storage methods, some of which may be impractical for smaller machines or need to be reversed before the motor goes into storage.
Customers sometimes send in a motor with no nameplate, or an illegible nameplate, having little knowledge of the machine’s ratings. This article will explore the process of evaluating the machine using frame size, winding data and test data to assign reasonable ratings.

To ensure the reliability of an RV’s electrical devices, especially electric motors, campers must know the service voltage of the hookup their RV is using. Teaching consumers to check that before they plug in the vehicle could save them many headaches.

Customers will often send in a motor with no nameplate and having little knowledge of the machine’s ratings. This webinar guides attendees through the process of evaluating the machine using core size, winding data and diagnostic testing to assign reasonable ratings.
ANSI/EASA AR100 is a must-have guide to the repair of rotating electrical machines. Its purpose is to establish recommended practices in each step of the rotating electrical apparatus rewinding and rebuilding processes.
What are the normal conditions for which a motor is designed? This is a question that does not often come up except when there is an issue with a motor application.
¿Cuáles son las condiciones normales para las que está diseñado un motor eléctrico? Esta es una pregunta que no surge muy a menudo, excepto cuando existe un problema con la aplicación.

This webinar recording discusses the equalized connections found in an increasing number of factory windings, explains why they are used, and addresses whether or not they are needed when converting a concentric winding to a lap winding. Alternatives, such as changing the number of circuits, or the special extra-long jumpers, are also compared.
Advancement in power electronics over the last few decades has made it possible to utilize a variety of rotating electric machines that would otherwise not be feasible. One such class of machines is called reluctance machines because of the way they produce an electromagnetic torque. A reluctance machine is an electric machine in which torque is produced by the tendency of its movable part to move to a position where the inductance of the excited winding is maximized.
