Motors deliver more efficiency than NEMA Premium

The NovaTorque Premium Plus+ motors offer higher efficiency and smaller size at a price competitive to current NEMA Premium induction motors.


Innovative design of Premium Plus+ motors offer improved efficiency and performance over NEMA Premium, NovaTorque Inc. of its new 2 and 3 hp at 1800 rpm motors of the company’s line of Premium Plus+ high efficiency electric motors. The NovaTorque Premium Plus+ motors offer higher efficiency and smaller size at a price competitive to current NEMA Premium induction motors. The motors are available direct from NovaTorque either as a motor system paired with a variable frequency drive (VFD) or standalone. The motors offer equipment manufacturers and customers a competitively priced step-up in performance and efficiency as the Energy Independence and Security Act of 2007, which mandates higher motor efficiency, is taking effect, the company said. The 2 hp Premium Plus+ motor has a full-load rated efficiency of 91.5% at the rating point of 1800 rpm; the 3 hp model has a full load rated efficiency of 90.5%. Full load NEMA Premium motor ratings are 86.5% and 89.5% for 2 and 3 hp motors respectively. Premium Plus+ motors maintain their high efficiency over a much wider speed and load range. The net result is a 5%-to-8% average improvement in operating efficiency over that of a NEMA Premium motor in a typical variable speed, variable load application, such as a fan or blower.
