1750 HP, 1800 RPM, NEMA Frame 8311, 2300/4000 V, WPII

GE Motors is proud to introduce its new line of medium & high voltage horizontal induction motors called Pegasus™ MHV. The design is a result of result of much hard work and investment in research, design and equipment. According to our latest market observations, this is truly a best-in-class product. Pegasus™ MHV yields more horsepower per frame size and improved efficiency along with power factor all awhile decreasing the overall weight of the motor. Pegasus™ MHV is offered in a range from 500 to 7000HP in NEMA or IEC designs.
