Whether you're selecting a motor for a new application or a replacement for one that has failed, you need a reliable way to match the capabilities and performance characteristics of various motors with the requirements of the application.

The topics covered included in this webinar recording:

• One circuit wye connection — Best, no parallel paths, turns per coil may prevent this
• Delta or multiple parallel circuits—Produces closed circuits, Circulating currents
• Open delta (4 wire connection)
• Permissible connections—Skip pole, adjacent pole
• Determined by speed combination

Bearing construction is a key difference between vertical motors and horizontal motors that are mounted vertically. Vertical motors typically drive pumps using thrust bearings. Horizontal motors rarely have those types of bearings. Understanding relevant construction and configuration factors is crucial when confronting lubrication-related issues that can be associated with vertical-motor bearings.

The Institute of Electrical and Electronics Engineers (IEEE) has published a new standard: IEEE Std. 3004.8-2016, “Recommended Practice for Motor Protection in Industrial and Commercial Power Systems.” If you’re an electrical professional who deals with a broad spectrum of motor protection schemes, including low- and medium-voltage AC and DC motors, then you need to become familiar with this standard.

This presentation covers who can perform repairs on hazardous location motors and what does it take to be certified

The nameplate of an electric motor reveals much valuable information about the capability and performance of the machine.

La placa de datos de un motor eléctrico revela mucha información valiosa acerca de la capacidad y desempeño de la máquina.

The Institute of Electrical and Electronics Engineers (IEEE) has published a new standard, IEEE Std. 3004.8-2016, “Recommended Practice for Motor Protection in Industrial and Commercial Power Systems.” This document provides guidance for motor protection for industrial and commercial applications. As motor service centers, the more we understand about the application and protection of motors in their applications, the better service we can offer to our customers.

El Instituto de Ingenieros Eléctricos y Electrónicos (IEEE) ha publicado una nueva norma, la IEEE 3004.8-2016: “Práctica Recomendada para la Protección de Motores en Sistemas de Potencia Industriales y Comerciales”. Los “libros de colores” están en proceso de revisión y actualización y sus designaciones cambiaron. Cada uno de los trece libros de la serie de normas de los “Libros de Colores IEEE” trata un aspecto diferente sobre la producción, distribución y uso de la energía eléctrica en sistemas de potencia industriales y comerciales; la 3004.8 reemplaza el Capítulo 10 del “Buff” book, IEEE 242-2001.

This presentation reviews the causes of axial thrust loading on bearings in motors and determine appropriate corrective actions.
