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 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.

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.

Hazardous location motors, often referred to as explosion-proof motors, are designed and tested for use in environments where fire or explosive hazards may exist due to flammable gases, vapors, combustible dusts, or ignitable fibers. These motors must contain any flame within the motor to prevent ignition of the surrounding atmosphere. Various standards govern the use of these motors, including those from Underwriter’s Laboratories (UL), Canadian Standards Association (CSA), International Electrotechnical Commission (IECEx), Mine Safety and Health Administration (MSHA), Factory Mutual (FM), Atmosphères Explosibles (ATEX), and British Approvals Service for Electrical Equipment in Flammable Atmospheres (Baseefa).
