Fasco D1143 Motor
The Fasco D1143 is an OEM replacement motor designed for versatile 3.3-inch diameter applications, commonly utilized in exhaust fans, evaporative coolers, and specific furnace configurations. This shrouded 115V HVAC motor operates at a fixed speed of 1550 RPM with a 1/20 HP output. Engineering specifications include a shaded pole motor design with a 1.1 amp draw, ensuring reliable performance in intermittent duty or continuous airflow environments. The 5/16-inch diameter shaft features a 2.5-inch length, facilitating compatibility with standard blower wheels. Utilizing sleeve bearings for quiet operation, this thermally protected motor is built for CCWSE rotation (Counter-Clockwise Shaft End). Contractors prioritizing efficiency will find the 3.3-inch unit bearing motor footprint ideal for tight installations where thermal resilience and precise direct drive motor specs are required for maintaining system static pressure and airflow ratings.
- Direct OEM interchange for seamless mechanical fit in existing blower housings.
- Sleeve bearing architecture minimizes vibrational noise during high-speed operation.
- Internal thermal protection prevents winding failure during restricted airflow conditions.
- Standard 5/16" shaft accommodates various fan blade and blower wheel bore sizes.
Common Installation Question: Can I use this motor if my original is rated for 1.0 amps?
Yes, the 1.1 amp rating on the D1143 is the maximum load capacity. It is compatible as long as the 115V voltage, 1550 RPM speed, and physical shaft dimensions match your existing application.
Common Installation Question: Does this motor support speed controllers?
This is a single-speed shaded pole motor. While some variable voltage controllers work, it is optimized for full-speed operation to maintain proper internal cooling.
Common Installation Question: How do I confirm the rotation direction?
The D1143 is rated for CCWSE (Counter-Clockwise Shaft End). Look at the end of the shaft; the motor must spin counter-clockwise to ensure correct airflow and prevent overheating.
