Consulting-Specifying Engineer - April 2008 - (Page 33) Save big money. Focus your energy on motors. One leading flooring manufacturer will save $1.7 million over the service life of 135 motors. If you’ve set your sights on cutting costs, consider the fact that electric motors account for about 70% of all electricity used in industrial settings. A switch to NEMA Premium® efficiency motors would do wonders for your bottom line. It’s working for Shaw Industries. They most recently replaced two motors that drive one of several tufting machines with much more efficient 15-hp NEMA Premium motors. Rated at 92.4% efficiency and constantly operating at 75% load, these two motors alone will save them 11,448 kWh each year. At their below-average energy rate of 5.8 cents per kWh, that translates to a savings of $666 on their annual utility bill and a payback period of a mere 18 months. When you consider that Shaw has over 130 additional motors that qualify for replacement, the savings potential is astonishing. In fact, they stand to save a whopping $1,771,560 over the motors’ expected 20-year service life. And that’s not even factoring in the hundreds of larger or special-purpose motors — which don’t fall within the NEMA Premium parameters — that Shaw also plans on replacing with more energy-efficient models. To learn how Shaw Industries and others are cashing in on NEMA Premium motors, call 888-480-MOTR or visit www.copper.org. We’ll also send you our helpful Energy Efficiency Motors and Transformers CD.
