September 09, 2003 by Jeff Shepard

The National Electrical Manufacturers Association (NEMA, Rosslyn, VA) announced that it has released MG 1-2003, Motors and Generators, a revised version of MG 1-1998. The new standard provides more than 500 pages of manufacturing and performance data related to electric motors and generators, and is designed to assist users in the proper selection and application of motors and generators.

Included in the new version is a section on NEMA Premium™ Efficiency Motors with expanded information on short-time-rated machines, and modifications in dimension tables and drawings. In addition, Part 5, "Classification of Degrees of Protection Provided by Enclosures for Rotating Machines," has been updated to align MG 1 with the IEC 60034-5 standard. MG 1 is revised periodically to incorporate changes in user needs, advances in technology and shifts in economic trends, and can be applied to any product that requires converting electric energy into mechanical energy.

The new MG 1-2003 standard is now available and is priced at $208.
