NovaTorque Inc.: Brushless Permanent Magnet Motors
Driven by variable-frequency drives, the Gen2.0 PremiumPlus+™ brushless permanent magnet motors have motor-only rated point efficiencies of 93 percent and 92 percent for 3- and 5-hp versions respectively. They are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution. Due to their high power density, the motors are available both in the mounting frame size typical for induction motors, as well as one frame size smaller. According to the manufacturer, PremiumPlus+™ motors are compatible with readily available VFDs from most leading manufacturers.
