NovaTorque (Fremont, CA) introduced 600 RPM versions of its PremiumPlus+® Electronically Commutated Permanent Magnet (ECPM) motors. The new versions are available from 0.75 HP to 3 HP, and are suited for directly driving larger-diameter fans at low speeds. The motors offer lower current requirements (FLA) than AC induction motor alternatives. A patented geometry allows for the use of readily available ferrite (versus rare earth) magnets. The motors are produced in standard NEMA frame sizes.
