Fasco D1139 Motor
The Fasco D1139 Motor is a high-performance shaded pole OEM replacement motor engineered for precision in HVACR equipment, specifically optimized for wood stoves like Buck Stove and Nashua models. Featuring a 1/50 HP output and operating at 1550 RPM, this 3.3-inch diameter motor provides reliable variable speed control with its 3-speed functionality (High-Black, Medium-Blue, Low-Red). Built for continuous duty in demanding environments, the Fasco D1139 utilizes a Totally Enclosed Air Over (TEAO) design with Class B insulation to manage internal temperatures effectively up to 40°C ambient.
This 115V AC motor is designed with sleeve bearings for quiet, long-term operation and includes automatic thermal protection to prevent overheating during heavy-use cycles. The double shaft design (2.5-inch and 1.125-inch extensions) with 5/16-inch diameters and flats ensures a secure fit for fan blades in multi-blower configurations. This 4-pole motor is a direct cross-reference for Dayton 38N534 and Regal Beloit specifications, making it the industry standard for 3.3-inch frame general purpose replacements.
Key Benefits of the Fasco D1139
- Multi-Speed Versatility: Features 3 distinct speed taps for customized airflow management in room heaters and air conditioning units.
- Robust Shaft Configuration: Equipped with a double shaft for versatile mounting and blower wheel compatibility.
- Optimized Cooling: The totally enclosed air over housing protects internal components from dust and debris common in wood stove applications.
- Direct Fit Compatibility: Specifically designed for Buck Stove 26000, 27000, and 28000 models, reducing installation time for contractors.
- Thermally Protected: Integrated auto-reset thermal overload ensures the motor shuts down safely if temperature limits are exceeded.
Common Questions
Is the Fasco D1139 compatible with variable speed controllers?
Yes, as a shaded pole motor with three speed taps, it is designed to work with standard multi-speed wiring or compatible variable speed switches for precise airflow tuning.
Which way does this motor rotate?
The Fasco D1139 is rated for Clockwise rotation (CWSE) when viewed from the shaft end opposite the leads (CWLE). Always verify your existing motor's rotation before finalizing the installation.
Can I use this for outdoor condenser units?
While it is thermally protected and totally enclosed, it is primarily sized and spec’d for 3.3-inch frame indoor blower and wood stove applications. Check the horsepower and RPM requirements of your specific unit first.
