Product Identity
The FASCO D181 is a shaded-pole HVAC motor rated at 1/30 horsepower and 1500 RPM on 115 V AC single-phase supply. It delivers 20 watts output from a 3.3 frame with stud mounting and a steel frame.
Suitability
Technicians replacing an original-equipment shaded-pole motor in residential air-handling equipment will find the correct speed, voltage and frame match here. Installations that require 208 V or 200 V operation, reversible rotation, or a different frame size should look elsewhere.
Deciding Specification
The motor is usable only at 115 V and is explicitly not usable at 208 V or 200 V, so the supply voltage is the single specification that determines whether this part fits the application.

Questions about this item
How is the 3.3 frame motor secured to the blower housing?
The motor uses a stud mounting type; the step often missed is tightening the stud nuts to the specified torque so the shaft stays aligned with the blower wheel.
What maintenance will the shaded-pole motor need after extended operation?
The open air-over enclosure relies on airflow for cooling, so the main task is keeping the motor vents and the blower wheel free of dust buildup.
At what ambient temperature does the Class B insulation reach its limit during continuous duty?
The motor is rated for a maximum ambient temperature of 40 degrees Celsius; sustained operation above that will trip the automatic thermal protection.
