Lower Horsepower Motor Consumes Less Energy
Morrill Motors®, a division of Regal Beloit, has released the ARKTIC 59, 1/20th HP motor, for walk-in coolers and freezers. ARKTIC 59 1/20th HP motor is a constant speed, brushless DC motor with an operating speed range of 500-1800 rpm. This lower horsepower ECM motor is similar in performance, mounting, and input connections to the standard ARKTIC 59 motor. It’s a drop-in replacement for 3.3-in. shaded pole(SP) and permanent split capacity (PSC) motors, with a second operating point for lower energy consumption. Morrill’s ARKTIC 59-series unit bearing ECM motors are primarily used in the evaporator of commercial refrigeration walk-in coolers and freezers. Sources say they significantly outperform shaded pole and PSC technology, with efficiencies three times higher than SP motors and 45% higher than PSC. In addition to the reliable and quiet ball bearing design, the ARKTIC 59 1/20th HP motor provides users with what sources say is the most reliable and best energy savings solution for low horsepower applications.
