Three-phase Electric Motors

WEG’s new NEMA W22 range of high and premium efficiency three-phase electric motors offer the highest levels of energy efficient performance, reducing losses by between 10% and 40%. Designed in 2, 4, 6 and 8-pole configurations, the NEMA W22 motors exceed the requirements of the new IE2 High Efficiency, and IE3 Premium efficiency classes. Key to their improved energy performance is a new aerodynamic frame, which increases airflow and reduces operational temperatures, and also a repositioned motor terminal box, which optimizes airflow over the motor. The W22 NEMA range of 60-Hz motors is initially available in frame sizes from 364T to 587T.
