Rosslyn, VA, June 16, 2003 -- NEMA has released General Specification for Consultants, Industrial and Municipal: NEMA Premium™ Efficiency Electric Motors (600 Volts or Less). This is the first time specific information has been developed to assist users and system designers in specifying the use of NEMA Premium™ Motors.
The intent of this specification is to outline the minimum requirements for three-phase AC induction motors applied to municipal and industrial applications for operation on voltages 600 volts or less, rated 500 horsepower or less, operating more than 2000 hours per year at greater than 75% of full load.
The NEMA Premium™ energy efficiency motors program, established by member companies of the NEMA Motor and Generator Section, provides highly energy efficient products that meet the needs and applications of users and original equipment manufacturers based on a consensus definition of "premium efficiency" and use of NEMA Premium™ logo for premium products.
NEMA Premium™ labeled electric motors help purchasers optimize motor systems efficiency, reduce electrical power consumption and costs, and improve system reliability. It is estimated that the NEMA Premium™ efficiency motor program would save 5,800 gigawatts of electricity. This is the equivalent of preventing nearly 80 million metric tons of carbon dioxide from being released into the atmosphere over the next 10 years or keeping 16 million cars off the road.
Joe Kline, technical committee chairman for the NEMA Motors and Generators section, says, "This specification was developed in a way such that fundamental technical requirements are clearly identified so the reader is fully versed in a step-by-step fashion."
The specification may be purchased for $31 by contacting Global Engineering Documents at 800-854-7179 (within the U.S.), 303-397-7956 (international), 303-397-2740 (fax), or on the Internet at www.global.ihs.com.
