NovaTorque Releases New Versions Of Its ECPM Motors
The 900 RPM versions are designed to deliver major efficiency gains at lower cost.
NovaTorque, Inc. has introduced 900 RPM versions of its 1.5, 2, 3, and 5 hp models. The new models provide a full load motor-only efficiency rating of 92% to 94% compared to approximately 82% to 87% for conventional AC induction motor ratings. Additionally, NovaTorque motors maintain high efficiency under partial load (AC induction motors do not), making NovaTorque motors ideal for variable speed fan applications. The efficiency advantage of a 900 rpm NovaTorque motor vs. an 8-pole 900 rpm AC induction motors can grow to 20 points or more at half-rated speed in such applications. That’s a 67% reduction in motor losses (wasted energy).
“There are many continuous-duty applications where required fan speed is in the 300 to 500 RPM range. For example, data center cooling applications — where high-flow and low-static pressure is desired — require a large diameter fan running at a relatively low RPM,” said Scott Johnson, VP Sales at NovaTorque. “To date, however, low speed direct drive applications haven’t been practical due to the high cost and low efficiency of 900 RPM 8-pole induction motors. NovaTorque’s 900 RPM ECPM motors change that paradigm with the combination of ultra high efficiency across a broad operating range at prices substantially lower than those of 8-pole induction motors.”
