Fasco D122 Motor

The Fasco D122 is a reliable shaded pole HVAC motor designed for low-torque applications such as exhaust fans, humidifiers, and small centrifugal blowers. This 1/80 HP unit runs on 115V single-phase power, drawing a steady 0.60 Amps at a rated speed of 1500 RPM. With a 3.3-inch frame diameter (3-3/8") and a CWSE rotation (Clockwise Shaft End), it serves as a common Fasco motor replacement for several OEM configurations. The motor features a Totally Enclosed Air Over (TEAO) enclosure, ensuring the internal components are shielded from dust and debris while utilizing the system’s airflow for cooling. Built with Class B insulation and thermal overload protection, it is engineered to handle an ambient operating temperature of up to 40°C. Installation is straightforward via the thru-bolt mounting pattern, and the 1/4" x 2-1/4" shaft provides ample length for various fan blade depths.

Key Benefits

• Standard 3.3" Frame: Fits most small blowers and ventilation units without bracket modifications.
• Internal Thermal Protection: Prevents stator burnout during locked-rotor conditions or voltage fluctuations.
• Sleeve Bearing System: Provides quiet operation and consistent performance in light-duty residential and commercial setups.
• TEAO Enclosure: Extends the service life of the 115V AC motor by preventing environmental contaminants from entering the windings.

Common Questions

What is the direction of rotation for the Fasco D122?
This motor is CWSE (Clockwise facing the shaft end). Always verify your existing fan blade pitch to ensure proper airflow direction before installation.

Can I use this to replace a higher HP motor?
No, this is a 1/80 HP shaded pole motor. Forcing a motor with lower horsepower to drive a larger load will lead to overheating and premature failure. Always match the HP and RPM specs of your original unit.

Does this motor require a capacitor?
No, the D122 is a shaded pole design, which does not require a start or run capacitor, simplifying the electrical wiring in your HVAC cabinet.
