Partnership Advances Motor Efficiency
December 12, 2001dustrial electric motor systems use roughly 23 percent of all electricity sold in the United States. Energy represents more than 97 percent of total motor operating costs. In large industrial plants, motor system energy costs can easily exceed $1 million annually. However, by installing energy efficient motors and applying good motor systems management techniques a company can reduce its motor systems energy costs by as much as 18 percent.
The National Electrical Manufacturers Association (NEMA) and the U.S. Department of Energy (DOE) have worked together to promote efficient industrial motor systems since 1993, when NEMA signed on as a harter Partnerin the former DOE Motor Challenge Program. In their continuing efforts to advance energy efficient motor systems, this year NEMA established a premium efficiency specification and brand for motors called NEMA Premium TM. A product must meet all of the NEMA-specified criteria in order to qualify as a NEMA Premium TM compliant electric motor.
DOE Office of Industrial Technologies continues to work closely with NEMA to promote NEMA Premium TM and motor system efficiency. DOE BestPractices and Federal Energy Management Programs are working with NEMA and the Motor Decisions Matter campaign to encourage the use of energy efficient motors as part of an overall approach to sound energy management.
NEMA and its motor and generator member companies have joined forces with several other organizations to initiate the Motor Decisions Matter campaign. Facilitated by the Consortium for Energy Efficiency, the nationwide campaign encourages the use of sound motor management and planning as a tool for cutting motor system energy costs and increasing energy efficiency. In doing so, industrial customers can help increase the reliability and quality of motor-driven process systems and reduce plant operating costs.
