Fasco K100 Motor
The Fasco K100 Motor is a high-performance C-frame shaded pole motor specifically engineered for continuous-duty HVACR applications, such as bathroom exhaust fans, range hoods, and humidifiers. This 1/100 HP unit operates at a synchronous speed of 2750 RPM on a 115V single-phase power supply, drawing a consistent 0.73 Amps. Designed with a CW rotation (clockwise facing the shaft end), it features a standard 0.181-inch diameter shaft with a 1.05-inch extension, ensuring a precise fit for round hub blower wheels and fan blades. The 0.62-inch iron stack and open air over (OAO) enclosure maximize heat dissipation, while the sleeve bearings and Class B insulation provide the reliable mechanical stability required by service contractors for high-cycle environments. With 1-7/8 inch center-to-center stud mounting, this direct replacement motor is the industry standard for restoring airflow in light-duty ventilation systems.
Key Benefits
- Universal C-Frame Design: The skeleton frame and extended studs facilitate seamless integration into a wide variety of OEM vent housings.
- High-Speed Efficiency: Rated at 2750 RPM, this motor delivers the high-velocity torque necessary for effective air evacuation in moisture-prone areas.
- Robust Thermal Protection: Includes automatic reset thermal overload protection to prevent winding failure during restricted airflow conditions.
- Quiet Operation: Precision-engineered sleeve bearings minimize vibration and acoustic noise, crucial for residential bath and kitchen installations.
- Broad Compatibility: Serves as a reliable cross-reference for various legacy Fasco and third-party models, simplifying inventory for field technicians.
Common Questions
Can the rotation of the Fasco K100 be reversed in the field?
No, this specific model is factory-set for CW rotation. If your centrifugal blower requires counter-clockwise movement, you should verify the rotation requirement before installation to avoid air cavitation or motor overheating.
What are the most common applications for this 1/100 HP motor?
The K100 is typically found in bathroom ventilator fans, small exhaust hoods, and evaporative cooler pumps where a compact, high-speed shaded pole motor is required for low-starting-torque loads.
How do I confirm if this motor fits my existing bracket?
Check the bolt spacing on your current unit; the K100 uses a standard 1.875-inch (1-7/8") mounting pattern. Additionally, ensure the 0.181-inch shaft diameter matches your fan blade hub.
