Engineering Institute Weighs-in on Efficiency As reported in the last issue of Update, energy consumption is expected to increase at a rate of 1.4 percent annually over the next 18 years, according U.S. Department of Energy (DOE). Switching to more-efficient motors, in the industrial sector as well as in the home, can make a significant contribution toward a more energy-efficient future in the USA. According to the IEEE-USA position statement, “through the proper application of energy-efficient technologies and processes, the United States will have greater resources available to compete in the global market while reducing environmental impacts and increasing energy security.” 
According to Dr. John Cowie, vice president of strip, sheet and plate at
the Copper Development Association Inc. (CDA) and program manager of the copper motor
rotor project, switching to premium-efficiency, copper motor rotors presents more opportunity
for energy savings and efficiency than any motor available today, “By switching
from a rotor with aluminum conductor bars to one with copper conductor bars, it is
possible to create a ‘super-premium’ efficiency motor surpassing even the premium-efficiency line of motors
currently available,” he said.
The IEEE-USA position statement presents several ways through which higher levels of energy efficiency can be achieved. Listed on the next page are the objectives where motor efficiency is a factor and how the Copper Development Association. is helping to meet those objectives on a commercial level. MORE >> |
