January 17, 2008, Rosslyn VA: The National Electrical Manufacturers Association (NEMA) has published MW 1 000 Revision 3 Magnet Wire. MW 1000 is the premier standards publication for general requirements, product specifications, and test procedures for the manufacture and packaging of magnet wire.
According to Sergio Peña Rojas, chairman of the NEMA Magnet Wire Section Technical Committee, MW 1000 is continually developed and maintained by the Magnet Wire Section to ensure that specifications and test procedures reflect evolving magnet wire end-user requirements and state-of-the-art magnet wire manufacturing technologies.
“This standard presents, in concise and convenient form, all existing NEMA standards for magnet wire, including standards for round, rectangular, and square film insulated and/or fibrous covered copper and aluminum magnet wire for use in electrical apparatus,” Peña Rojas said. “MW 1000 contains the definitions, type designations, dimensions, constructions, performance, and test methods for magnet wire generally used in the winding of coils for electrical apparatus.”
This revision includes expanded performance and dimensional requirements for half-AWG wire sizes, new solderability requirements for MW 79-C and MW 80-C, new MW 64-C and MW 65-C specifications, and a new table of solderability immersion times.
MW 1000 is approved as an American National Standard through an accredited canvass of the American National Standards Institute (ANSI), and is endorsed by Electro-Federation Canada (EFC) for use in Canada and by La Asociación de Normalización y Certificación del Sector Eléctrico (Association of Standardization and Certification of the Electrical Sector (ANCE) for use in Mexico.
