Brushless Permanent Magnet Motors

January 26, 2012

NovaTorque’s Gen2.0 PremiumPlus+™ brushless permanent magnet motors, driven by variable frequency drives, boast motor-only rated point efficiencies of 93.0 percent and 92.0 percent for 3hp and 5hp versions respectively, far exceeding the levels achieved with induction motors, according to the manufacturer. By comparison, 3hp and 5hp NEMA Premium® induction motors, when driven by variable frequency drives, achieve a motor-only efficiency of between 88.5 and 90.0 percent. NovaTorque PremiumPlus+™ motors are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution.
