WEG Electric’s W40 three-phase induction motors are designed for compressors, blowers, oil well and fire pumps and industrial refrigeration applications. All models meet or exceed NEMA standards and international efficiency requirements. The W40 motor line features a rated output of 60 Hz at 15 to 2,250 hp as well as 2- or 4-pole models in NEMA frame sizes from 254T – L6808/09.
