New 7.5 hp and 10 hp horsepower models have been added to the company's line of high-efficiency permanent magnet motors. All motors in the line use low-cost ferrite magnets in a flux-focusing design to deliver the efficiency of rare-earth permanent magnet motors at a price that is competitive with induction motors. The new motors, designed to be driven by variable frequency drives, have motor-only rated point efficiency of more than 94 percent, a 3 point advantage over NEMA Premium induction motors. Under partial load the typical efficiency improvements ranges from 5% to 15%. In a high duty cycle 10 hp fan application in an average cost of power area, annual energy cost savings can exceed $300. The motors are packaged in standard NEMA frame sizes and mounting dimensions for easy substitution of AC induction motors, and are compatible with readily available variable frequency drives from most leading manufacturers, including ABB, Yaskawa, Mitsubishi, Siemens, Fuji, Hitachi, Toshiba, Delta, Danfoss, Schneider, Vacon and others.
