An Arthur D. Little report concluded that motors use 62 percent of all power generated in the US. This fact created a powerful incentive to accelerate development of higher-efficiency motors. The combination of the report results and rapidly escalating power costs has caused all motor manufacturers to re-examine their motor designs. Various ways to improve efficiency are to use thinner steel laminations in the stator and rotor core, use steel with better electromagnetic properties, add more steel, increase wire volume in the stator, improve the rotor slot design and insulation, and use smaller, more efficient fans. These innovations result in a higher-priced motor, so companies must consider offering a separate line of high-efficiency motors to its customers along with the conventional ones. The factors to be considered by a firm on whether to purchase a high-efficiency motor are discussed, namely: starting torque, acceleration, horsepower, duty cycle, motor environment, efficiency, power, factor, and first cost.
