Motor and Generator

The member companies in the Motor and Generator Section are committed to providing high quality, energy efficient, and safe motor and generator products to the public. It works to ensure that the interests of the consumer and industry are addressed in technical, government, and market activities. The domestic industry represents about $5 billion in motor and generator shipments covering the commercial, industrial, institutional, and specialty motor/generator markets.

The NEMA Motor and Generator Section established a NEMA Premium® energy efficiency motors program to provide high energy efficient products that meet the needs and applications of users and original equipment manufacturers.

Look for and specify NEMA Premium® to optimize motor systems efficiency, reduce electrical power consumption and costs, and improve system reliability.

Technical Activities

Standards play a vital part in the design, production, and distribution of products destined for both national and international com­merce. Sound technical standards benefit the user, as well as the manufacturer, by improving safety, bringing about economies in product, eliminating misunderstandings between manufacturer and purchaser, and assisting the pur­chaser in selecting and obtaining the proper product for his particular need.

NEMA devotes much of its time, effort, and resources to voluntary standardization activities. NEMA standards are offered and recommended to become American National Standards under the procedures of the American National Standards Institute, usually under the canvass method. This decision rests with the particular subdivision or subdivisions concerned. NEMA standards are also often submitted for consideration as IEC standards components or references. It is the intent of the association to continue its support of these, and many more, activities as the best method to continue providing sound and safe electrical products for the use of all.

For the Motor and Generator Section, a large component of its technical work centers on the development and maintenance of NEMA Standard MG 1-2016, Motors and Generators.

For 2017 and 2018, technical activities include:

  • Development and updating of motor and generator standards, including MG 1-2016
  • Development and publication of the first edition of NEMA SM 1, Guide to General-Purpose Synchronous Motors Without Excited Rotor Windings
  • Harmonization and development of North American (UL 1004 and CSA C22.2 No. 100) motor safety standards
  • American National Standards, C50 on rotating machinery
  • Contributing to NEMA positions on amendments proposed for the 2020 National Electrical Code.
