NovaTorque Inc. Expands Its Ultra Efficient PremiumPlus+(TM) ECPM Motor Line

By using low-cost ferrite magnets in an innovative flux-focusing design, NovaTorque motors deliver the superior efficiency of rare-earth permanent magnet motors at a price that is competitive with induction motors in a power range of 2hp to 10hp

Fremont, CA — NovaTorque, Inc. (, a Fremont CA based producer of ultra efficient, cost-effective, electronically commutated permanent magnet motors, will introduce new higher 7.5hp and 10hp horsepower models of its PremiumPlus+™ motors at the AHR Expo, January 21-23, 2014 at Javits Center, New York City, NY. NovaTorque will be exhibiting in booth 7182. 

“NovaTorque’s new 7.5hp and 10hp versions, driven by variable frequency drives, boast motor-only rated point efficiency of over 94 percent, a full 3 point advantage over NEMA Premium induction motors. That advantage grows under partial load, as is the case in variable speed fan applications, with typical efficiency improvements ranging from 5% to 15%. In a high duty cycle 10hp fan application in an average cost-of-power area, annual energy cost savings can exceed $300”, says Scott Johnson, NovaTorque’s Vice President of Sales. “The advantage is even more dramatic when compared to the current installed base of induction motors, where efficiency improvements of 20 percent or more are achievable,” continues Johnson.

NovaTorque Electronically Commutated Permanent Magnet motors reduce motor losses (wasted energy) by 30% to 50%. In typical variable speed fan applications that translates into a 5% to 15% energy savings when compared to NEMA Premium induction motors – and much greater savings when compared with the current installed base. Importantly, NovaTorque motors have been designed to compete on a first cost basis with induction motors, providing a rapid payback on the modest price premium.

Importantly, due to its unique patented flux-focusing stator and rotor hub geometry, the NovaTorque motor produces this performance with an all-ferrite (versus rare earth) magnet design. 

“The cost of rare earth (neodymium) magnet material, the basis of most conventional permanent magnet motors, has risen erratically over the last several years. Further, supply of rare earth magnets is increasingly uncertain. The ability to use ferrite magnets allows NovaTorque to price its motors comparable to induction motors. This means OEMs and HVAC systems builders can now economically deliver superior permanent magnet motor efficiency with modest first cost impact and a rapid payback,” explains Jaffer Hussain, NovaTorque’s Vice President of Marketing and Product Management.

NovaTorque PremiumPlus+™ motors are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution of AC induction motors. NovaTorque PremiumPlus+™ motors are compatible with readily available variable frequency drives (VFDs) from most leading manufacturers, including ABB, Yukawa, Mitsubishi, Siemens, Fuji, Hitachi, Toshiba, Delta, Danfoss, Schneider, Vacon and others. 


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).
