Organization releases NEMA MG 1-2009, Revision 1-2010, "Motors and Generators"
Rosslyn, Va.-based Electrical Manufacturers Association (NEMA) has published NEMA MG 1-2009, Revision 1-2010, "Motors and Generators." The standard is produced by NEMA’s Motor & Generator Technical Committee and is frequently revised to reflect changes in technology.
MG 1 is the definitive standard for practical information concerning performance, safety, testing, construction, and manufacture of alternating-current and direct-current motors and generators. It provides access to fundamental testing and dimensional and application criteria relative to rotating machinery.
This newest revision features extensive revisions to Part 7 of the standard, covering mechanical vibration, and an addition to Part 14 on application data.
“With each revision, MG 1 becomes more useful to manufacturers and users of motors and generators,” says Roger Daugherty, Ph.D., of Baldor Electric Co. and chair of the technical committee. “The members of NEMA’s Motor and Generator Technical Committee work diligently to ensure that this standard is a comprehensive resource for anyone working with these product types, and I hope readers will find this newest revision to be a beneficial addition to their standards libraries.”
To increase the publication’s utility and readability, the standard also includes a summary of changes for the current revision as well as the four previous editions, with color-coded lines throughout the document to mark affected sections.
