The National Electrical Manufacturers Association (NEMA) has published MG 1, Revision 1 “Motors and Generators”. The standard is produced by NEMA’s Motor & Generator Technical Committee.

“With each revision, MG 1 becomes more useful to manufacturers and users
of motors and generators,” said Roger Daugherty, Ph.D., of Baldor
Electric Co., who chairs the Technical Committee.

NEMA says MG 1 is the definitive standard for practical information
concerning performance, safety, testing, construction and manufacture of
alternating- 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.

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 colour-coded lines throughout the document
to mark affected sections.
