The Unitronix, stock number 9207, is a high-efficiency,
multiwatt output replacement motor. The supermarket case evaporator fan motor
is an electronically commutated motor (ECM) that can replace a variety of OEM
shaded pole evaporator fan motors. It is designed as a 3-in-1TM
multiwatt output motor. This allows it to replace 6-, 9-, and 12-W PSC and
less-efficient shaded pole unit bearing motors. According to the manufacturer,
using it as a retrofit to replace shaded pole OEM motors can save the user up
to 65 percent in energy usage. The motor uses less wattage to achieve the same
airflow as a shaded pole motor, so it produces less heat, and fewer Btu in the
system means less work for the compressor and reduced compressor wear, claims
the company. Bulletin 6029 on the motor is available for download at
