PremiumPlus+™ motorsNovaTorque, Inc. has introduced its next-generation design of 3hp and 5hp PremiumPlus+™ motors, which boast motor-only rated point efficiencies of 93.0 percent and 92.0 percent for 3hp and 5hp versions, respectively. According to the company, the motors are further characterized by:

  • A brushless permanent-magnet design, driven by variable frequency drives. 
  • A unique, patented flux-focusing stator and rotor hub geometry.
  • The motors produce this performance with an all-ferrite (versus rare earth) magnet design. 
  • The motors are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution. 
  • Due to their high power density, they are available both in the mounting frame size typical for induction motors, as well as one frame size smaller. 
  • They are compatible with readily available variable frequency drives (VFDs) from most leading manufacturers, including ABB, Yaskawa, Mitsubishi, Fuji, Hitachi, Toshiba and others.
