Permanent Magnet Motors - NovaTorque, Inc.


NovaTorque Inc.’s family of Gen2.0 PremiumPlus+™ Electronically Commutated Permanent Magnet (ECPM) motors will soon be available in high speed 3hp and 5hp 2400 rpm (maximum speed 3600 rpm) models. Also available in 3hp and 5hp 1800 rpm models (maximum speed 2700 rpm), NovaTorque motors utilize low-cost ferrite magnets in an innovative flux-focusing design to deliver the superior efficiency of rare-earth permanent magnet motors at a price that is competitive with induction motors. 

Driven by variable frequency drives, Gen2.0 PremiumPlus+ ECPM motors boast motor-only rated point efficiencies of 93.0 and 92% percent for 3hp and 5hp versions respectively, far exceeding the levels achieved with induction motors. Additionally, unlike induction motors, NovaTorque’s PremiumPlus+ ECPM motors maintain their high efficiency and high torque over a very broad speed and load range. 

NovaTorque PremiumPlus+ motors are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution. Due to their high power density, NovaTorque motors are available both in the mounting frame size typical for induction motors, as well as one frame size smaller. NovaTorque PremiumPlus+ motors are compatible with readily available variable frequency drives (VFDs) from most leading manufacturers, including ABB, Yaskawa, Mitsubishi, Fuji, Hitachi, Toshiba, Danfoss, Siemens and others.
