Fasco D128 Motor

The Fasco D128 Motor is a high-versatility, 3.3-inch diameter shaded pole motor designed for light-duty air-moving applications, including evaporator fans, range hoods, and small blowers. This 115V multi-horsepower unit is engineered to operate at 1/40-1/50-1/80 HP, allowing technicians to consolidate truck stock by replacing multiple single-speed motors with one reliable component. Operating at a synchronous speed of 1500 RPM, the motor features a double-shaft design (4" x 5/16" x 4") with a flat, making it a functional drop-in for HVAC blower motor replacement in restricted spaces.

Built for continuous duty in Open Air Over (OAO) environments, the Fasco D128 utilizes sleeve bearings and automatic thermal overload protection to ensure operational stability under standard load conditions. With its 3-speed capability (Black-High, Blue-Med, Red-Low), this motor provides precise airflow control without the need for a start capacitor. The 3.3-inch frame motor is commonly cross-referenced with various OEM parts, servicing as a robust solution for refrigeration motor retrofits and general-purpose ventilation tasks where quiet, multi-speed performance is required.

• Multi-HP Versatility: Covers 1/40, 1/50, and 1/80 HP ratings in a single unit to reduce inventory overhead.
• Double Shaft Design: 5/16" diameter shafts extending 4 inches from both ends support diverse blower wheel configurations.
• Simplified Wiring: 3-speed shaded pole design eliminates capacitor maintenance and streamlines installation.
• Thermal Protection: Integrated automatic reset prevents winding failure during restricted airflow or over-temperature events.
• Industrial Build: Features Class B insulation and sleeve bearings optimized for 40°C ambient temperatures.

Can I use this motor to replace a single-shaft unit?
Yes. For single-shaft applications, the unused shaft end can often be trimmed or positioned within the housing, provided there is adequate clearance for the 10.63-inch overall length.

What is the correct rotation for the D128?
The Fasco D128 is designed with double shaft rotation, effectively allowing it to serve applications requiring either direction depending on which shaft end is utilized relative to the lead end.

Is a capacitor required for this motor?
No. As a shaded pole motor, the D128 operates directly on 115V AC power without an external start or run capacitor.
