Horizontal and vertical motors have uniquely different requirements for endplay, while sleeve bearing machines bring their own challenges. This presentation examines those differences.

The information in this article provides comparisons of key characteristics of IEC and NEMA motors to aid in evaluating the potential simplicity or complexity of the IEC to NEMA design conversion.

En este artículo, se profundizará en los motores de CA responsables de las funciones de inclinación y elevación de las apiladoras de troncos. Estos motores poseen características distintivas, incluido un rotor de alta resistencia.

La información de este artículo proporciona comparaciones de las características clave de los motores IEC y NEMA para ayudar a evaluar la posible simplicidad o complejidad de la conversión de diseño IEC a NEMA.

This video shows the proper way to lubricate the deep-groove, open ball bearing before assembling a horizontal induction motor.

This video shows the proper procedure for seating carbon brushes in a DC machine.

This video will walk you through how to check the relative polarity of DC machine interpoles and the armature and correct it if necessary using a simple interpole polarity test.

This video demonstrates the correct way to use an induction bearing heater to install an interference fit ball bearing on a machine shaft.

When working with DC machines, it’s not uncommon to find a customer who runs different products requiring a range of armature current. Unlike other conductors, where lower current is a good thing, carbon brushes are designed for a narrow range of current density. A unique aspect of carbon brush life is that brushes operating at a much lower current density than they are designed for do not last nearly as long as expected.

Being proactive on behalf of the repair industry, EASA created the best practice repair standard for the industry. This article looks back on this history of this important document.
