Engineering Institute Weighs-in on Efficiency (continued) Energy User Awareness and Incentives IEEE-USA states: “IEEE-USA recommends user awareness programs sponsored by government, utilities and organizations. . . . These programs have helped users realize the benefits and cost effectiveness of energy efficient technologies and processes.” CDA is a sponsor of the Consortium for Energy Efficiency’s Motor Decisions MatterSM Campaign, which aims to help businesses control costs through better motor management. Additionally, through intensive, hands-on seminars, the technological achievements of the copper motor rotor program are shared with businesses interested in utilizing this new process. Generation, Delivery, Conversion IEEE-USA states: “Power conversion processes, such as accomplished by electric motor systems, consume the largest share of electrical energy and provide one of the largest opportunities for energy efficiency.” According to Cowie, the level of energy efficiency being achieved through the copper motor rotor project exceeds the efficiency of currently produced motors using aluminum rotors as well as any efficiency guidelines in place by the DOE. Industrial Processes IEEE-USA states: “Replacing older, less-efficient motors with new, high-efficiency motors will typically improve efficiency by three to eight percent. This type of change-out can achieve an estimated 18 percent of the total electric system savings opportunity in the industrial sector.” “Independent tests on the copper motor rotors were performed by a motor company that replaced their existing motor rotors with copper,” Cowie explained. “The motor sizes were 3kW, or 4 hp. The efficiency test results show a reduction in overall loss exceeding 20 percent, without even measuring stray load losses.” Cowie concluded, “As energy demand in the USA continues to increase, more energy-efficiency practices and processes are warranted. The technological advances made through the copper motor rotor project can play a significant role in controlling the overall energy demand of the USA.” For more information on IEEE-USA and their policy, go to www.ieeeusa.org.
