NovaTorque’s 900 RPM Version boots efficiency rating up to 94 percent.
NovaTorque, Inc. unveiled 900 RPM versions of its 1.5, 2, 3 and 5 hp motor models that provide a full load motor-only efficiency rating of 92% to 94% compared to approximately 82% to 87% for conventional AC induction motor ratings. Additionally, the motor maintains high efficiency under partial load. According to the company, the motor’s flux focusing stator and rotator technology offers the ability to spec a motor one full frame size smaller than conventional induction motors. The NovaTorque motor achieves this efficiency gain, and smaller size, with an all-ferrite (versus rare earth) magnet design. NovaTorque motors are packaged in standard NEMA frame sizes and mounting dimensions. NovaTorque motors are compatible with readily available variable frequency drives (VFDs) from most leading manufacturers.
