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 article explains in layman’s terms what electromechanical professionals refer to as circulating currents, why they exist in three-phase electric motors and to offer practical solutions. 

Este artículo es explicar en términos sencillos a qué se refieren los profesionales de la electromecánica como corrientes circulantes, por qué existen en los motores eléctricos trifásicos y ofrecer soluciones prácticas.

When repairing centrifugal and axial flow pumps, axial thrust is a concern. An understanding of the causes and the mitigating provisions of various pump designs will help repair technicians to ensure those provisions work properly.

Unlike their AC counterparts, DC machines do not have rotating magnetic fields. Rather, there are fixed magnetic field axes for the field (direct axis) and armature (quadrature axis). Even though the armature is rotating, the magnetic field axis in the armature is fixed thanks to commutation, which allows the direction of current in an armature conductor to change as it passes from the region under one main field pole to the next.
