Permanent Magnet EC Motors operate up to 2,400 rpm.

Press Release Summary:




Intended for fan applications, 2,400 rpm Permanent Magnet EC Motors are available in 3–15 hp models, with rated efficiencies of 93.5–95%. Units feature all-ferrite magnet design and are produced in NEMA dimensions to facilitate substitution. When compared with NEMA Premium induction motors, 2,400 rpm motors offer 30–50% reduction in motor losses and 5–20% reduction in energy usage.

NovaTorque Fills Void in Fan Application Speed with Introduction of 2400 RPM Permanent Magnet EC Motor



Fremont, CA — NovaTorque, Inc. (www.novatorque.com) has introduced 2400 rpm versions of its 3hp through 15hp models, with rated efficiencies of 93.5 to 95%.



Until now, when the desired operating point of a fan fell in the 2200 to 3200 rpm range, the designer was left with less than optimum choices.  One could over-speed a 4 pole 1800 rpm motor or turn down a 2 pole 3600 rpm motor.  Both choices result in a significant loss of efficiency, and the 3600 rpm choice often results not only in the reduction of efficiency, but also the need to move up to the next HP rating, adding costs to both motor and variable frequency drive (VFD). 



NovaTorque’s innovative motor design has opened the door to the creation of a number of motor models with new speed ratings, including its unique 2400 rpm motor offerings.  This will allow designers to select a motor with a rating much closer to the ideal operating range of the fan.  Further, in many cases, the motor will be one full frame size smaller than the alternative AC induction motor, reducing weight, cost, and possibly VFD size.



In addition to the unique speed rating, NovaTorque’s 2400 rpm motors retain all the advantages of its 900, 1200, 1800, and 3600 rpm line of motors.  These include: 30% to 50% reduction in motor losses and 5% to 20% reduction in energy usage when compared with NEMA Premium induction motors.  NovaTorque motors are compatible with all leading VFD brands.  They are produced in NEMA dimensions for easy substitution, and the all-ferrite (versus expensive rare earth) magnet design allows them to be priced competitive with AC induction motors



ABOUT NOVATORQUE, INC.

Based in Fremont, CA, NovaTorque is a producer of electronically commutated permanent magnet electric motors. The Company is dedicated to delivering the superior energy efficiency of permanent magnet motors at price points more comparable to the common AC induction motor. NovaTorque accomplishes this through an innovative flux-focusing design that allows for the use of ferrite rather than rare-earth magnets. The Company is an active member of the Air Movement and Control Association (AMCA) and National Electrical Manufacturers Association (NEMA).
