ECM 142R is the next generation of high-efficiency, fractional-horsepower outdoor motors. 142R is ideally suited to outdoor applications such as split system outdoor units, package units, or any other prop fan air-moving that requires a 1/5, 1/3, 1/2 or 3/4 horsepower, 300-1200 RPM motor. Side-by-side with an induction motor, the new ECM uses 20% less power.
This generation of ECM combines over 20 years of development in residential HVAC and many millions of field installations, creating a motor with warranty return rates low enough to rival conventional permanent-split capacitor (PSC) motors. ECM 142R also features speed ramping for decreased fan noise, BlaKBox™ Diagnostics for reporting field data back to manufacturers, and a PSC-like speed-tap interface that service technicians have been using for years.
ECM 142R maintains its high efficiency across a range of operating speeds, which results in a significant reduction in energy use when the motor is run at reduced speeds. This makes the 142R ideal for use in creating two-stage outdoor compressors and heat pump-type units. In addition to reducing electrical use, two-stage compressors feature enhanced humidity removal, less temperature swing between cycles, more even temperatures throughout the home, and quieter equipment operation (especially when combined with a fully-variable ECM ThinkTank™ indoor blower motor).
