NEMA Revises Guide to Motors and Generators, NEMA MG 1-2016

October 5, 2016

The National Electrical Manufacturers Association (NEMA) has revised NEMA MG 1-2016 Motors and Generators.

NEMA MG 1 helps users select and apply motors and generators. It contains practical information concerning performance, efficiency, safety, testing, construction, and the manufacture of AC and DC motors and generators.

“These enhancements deal with a wide range of topics, including new requirements that promote durability of definite purpose inverter-fed polyphase motors rated 600 volts or less, guidance for procedures to utilize during efficiency and temperature rise testing, and clarification on nameplate marking requirements and on tolerances that can be observed for performance characteristics,” explains Steve Ruffing, Vice Chair of the Technical Committee of the NEMA 1MG Section and Senior Design Engineer at Nidec Motor Corp.  

Common examples of motors that rely on MG 1 include those that power production machinery in manufacturing plants, oil field exploration and recovery, heating and air conditioning, and essential components of portable water and fire protection pumping systems.

NEMA MG 1-2016 is available in hard copy or as an electronic download for US$448 on the NEMA website: www.techstreet.com/nema/products/1929069.
