Fasco UB564 Motor

The Fasco UB564 Motor is a high-efficiency 9W shaded pole motor designed specifically for refrigeration and ventilation applications requiring consistent 1550 RPM performance. Operating at 230V, this unit serves as the direct replacement for Fasco D564, ensuring seamless mechanical compatibility without the need for mounting modifications. This motor features a CWOSE rotation (Clockwise Opposite Shaft End) and utilizes an impedance-protected design to prevent thermal failure during locked-rotor conditions. For technicians servicing commercial reach-ins or exhaust fans, the UB564 refrigeration motor provides a reliable 0.50 Amp draw, making it an ideal drop-in solution for maintaining system static pressure and airflow. Its compact 3.3-inch frame and standard hub mounting allow for quick installation in tight plenums. When sourcing a replacement fan motor, verifying the Fasco UB564 specifications against the existing blower wheel pitch is essential for optimal motor longevity and heat dissipation.

Key Benefits

• Direct Interchangeability: Engineered as the exact Fasco D564 replacement to eliminate field retrofitting time.
• Optimized Thermal Management: Shaded pole design provides natural internal overload protection for continuous duty cycles.
• Reliable RPM Consistency: Maintains 1550 RPM under standard load to ensure rated CFM output in refrigeration circuits.
• Moisture Resistance: Built to withstand the high-humidity environments typical of evaporator and condenser applications.
• Standardized Fitment: Features a universal shaft diameter and mounting pattern common in HVAC mechanical duty motors.

Common Questions

Is the UB564 compatible with variable speed controllers?
No, this is a fixed-speed shaded pole motor designed for single-speed 230V operation; using a triac or VFD may cause premature winding failure.

What is the rotation direction of the Fasco UB564?
The motor is rated for Clockwise Opposite Shaft End (CWOSE) rotation; always verify the fan blade pitch matches this orientation before installation.

Can I use this motor to replace a 115V unit?
No, the UB564 is strictly a 208-230V component. Applying 115V will result in insufficient torque and motor stall, while over-voltage will burn the windings.
