The National Electrical Manufacturers Association (NEMA) released Aug. 26 its revised Motors & Generators, MG 1-1998, standard. Designed to help users properly select and apply motors and generators, MG 1-1998 provides practical information on performance, safety, test, construction, and manufacture of ac and dc motors and generators. It also includes data on installation and use problems as described by manufacturers, users, inspection authorities, and others with specialized experience. MG 1-1998 is available through Global Engineering Documents (Englewood, Colo.). The standard is revised periodically to address changes in users' needs, technology advances, and economic trends. The new MG 1-1998 contains several important additions and revisions. For example, Parts 30 and 31 on inverter-fed motors address evolving technology; generator information is combined in a simpler Part 32; and a newly revised Part 4 combines dimensional data from former Parts 4 and 11.
