AC Induction Motors

Some of the largest opportunities to save energy and reduce operating costs in buildings and industrial facilities come from optimizing electric motor systems. About half of all electricity consumed in the U.S. flows through motors, 90 percent of which are alternating-current (AC) induction motors. The U.S. Department of Energy (DOE) estimates that on average, the manufacturing sector could reduce industrial electric motor energy use 11 to 18 percent by using proven efficiency technologies and practices. In a single year, a fully-loaded motor operating continuously can consume energy worth about 10 times its initial cost. That's why even small improvements in efficiency can pay back quickly. The key is to choose the right-sized, energy-efficient motor and to integrate it into an optimized drivepower system.
