NovaTorque Permanent magnet EC motor
The 3- through 15-hp permanent magnet EC motor models are available in 2,400-rpm versions, with rated efficiencies of 93.5 to 95%. The new speed rating will help designers to select a motor with a rating closer to the fan’s ideal operating range. In certain instances, the motor will be one full frame size smaller than the alternative ac induction motor. The motor is compatible with many VFD brands, and it’s designed to provide 30 to 50% reduction in motor losses and 5 to 20% reduction in energy usage when compared with NEMA Premium induction motors. The motors are produced in NEMA dimensions.
