Ao Smith 322 Shaded Pole Motor 1/25 Hp 115V 1550 Rpm

Product Description

The AO SMITH 322 is a shaded pole motor rated at 1/25 horsepower and designed for single-phase, 115-volt AC applications. Running at 1550 RPM and drawing 1.4 amps, this motor operates in a 4.3 frame size with an open-air enclosure and sleeve bearing construction. Counterclockwise rotation is measured from the lead end. HVAC technicians and equipment service pros install this motor in low-torque, continuously running applications where compact size and reliable low-speed operation are required.

This motor is suited for residential and light commercial HVAC equipment, including evaporator fan assemblies, draft inducers, and other auxiliary blower applications that demand a compact, low-horsepower shaded pole design. Its single-speed, open-air configuration makes it a direct-fit replacement in equipment that specifies a 4.3 frame shaded pole motor with a 7.25-inch shaft and 0.5-inch shaft diameter.
