There are a lot of factors to take into consider when interpreting the bar-bar test or surge test. This articles reviews those factors.

Hay muchos factores a tener en cuenta al interpretar la prueba de barra-barra o la prueba de sobretensión. Este artículo revisa esos factores.

As EASA members, we have the technical skills, knowledge and support to do almost anything in the electromechanical repair industry. Rail work is no different.

The US Department of Energy (DOE) has issued rulemaking on test procedures for small electric motors for more than a decade. The present “final rule,” effective February 3, 2021, is the culmination of those efforts.

EASA's DC Machine Data Sheet provides all the fields necessary on a simple one-page form to accurately record all the details about the machine being repaired.

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.

Determining the source of noise in a motor is often much more challenging than correcting it. However, a methodical approach to investigating the noise can narrow down the possible causes and therefore make it easier to resolve the noise issue. There is a caveat. If the cause of the noise is due to something in the motor design, that is, a manufacturing defect or anomaly, a solution may not be possible or practical.
