September 13, 2015 - NovaTorque introduced 900 RPM versions of its 1.5, 2, 3 and 5 hp models that provide a full load motor-only efficiency rating of 92% to 94% compared to approximately 82% to 87% for its conventional AC induction motor ratings.
The motors maintain high efficiency under partial load, making them ideal for variable speed fan applications.
An additional benefit of flux focusing stator and rotator technology is the ability to often be one full frame size smaller than conventional induction motors, providing substantial weight and space savings. The motor achieves this efficiency gain, and smaller size with an all-ferrite (versus rare earth) magnet design, which provides a substantial cost benefit over conventional permanent magnet motors using costly rare earth materials.
NovaTorque motors are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution of AC induction motors. NovaTorque motors are compatible with readily available variable frequency drives (VFDs) from most leading manufacturers, including ABB, Yaskawa, Mitsubishi, Siemens, Fuji, Hitachi, Toshiba, Delta, Danfoss, Schneider, Vacon and others.
