HVAC Unit Bearing Motor
The FASCO UB566 is a single-phase shaded-pole motor rated at 1/50 HP and 16 output watts. It runs on 115 V AC at 60 Hz, draws 0.8 A full-load current, and turns clockwise at 550 RPM. The totally enclosed air-over enclosure and continuous duty cycle suit HVAC control applications.
Shaded-pole HVAC replacement
This motor fits technicians replacing a 115 V shaded-pole unit bearing motor in fan or blower assemblies that accept a rear double-foot mount. It is not for systems requiring 200 V or 208 V operation, multi-speed control, reversible rotation, or a standard NEMA frame. Buyers needing higher horsepower or different voltage should look elsewhere.
Mounting and thermal features
The rear double-foot mounting simplifies direct replacement in compatible HVAC housings. Automatic thermal protection and Class B insulation protect the windings during continuous operation at up to 40 °C ambient. No separate capacitor, speed control, or wiring harness is included in the package.

Questions about this item
What voltage supply and mounting style does the FASCO UB566 motor require for installation?
The motor runs on 115 V AC single-phase power and mounts with a rear double-foot bracket, so the installer needs a 115 V circuit and a surface that accepts that foot pattern.
Can the FASCO UB566 replace an existing shaded-pole motor that runs at 208 V or 200 V?
The specifications list usable at 208 V and 200 V as No, so the UB566 cannot be used on those voltages; it is rated for 115 V only.
How can I confirm the FASCO UB566 is operating correctly after wiring it up?
With power applied, the shaft should turn clockwise (CWLE) at 550 RPM, draw about 0.8 A, and the motor housing should stay within the 40 °C maximum ambient temperature limit.
