FASCO UB568 Unit Bearing Motor
The FASCO UB568 is a single-phase shaded-pole motor rated at 1/50 HP and 16 W output. It runs at 550 RPM on 230 V AC at 60 Hz, drawing 0.4 A full-load current. The totally enclosed air-over enclosure carries Class B insulation and automatic thermal protection for continuous duty up to 40 °C ambient. Mounting is via a rear double-foot pattern with a clockwise lead-end shaft rotation.
Installers replacing original-equipment
This motor suits technicians servicing HVAC equipment that specifies a 1/50 HP shaded-pole unit with a non-standard frame and rear double-foot mount. It is not for applications requiring multi-speed operation, reversible rotation, or a standard NEMA frame. Buyers needing 208 V or 200 V compatibility should look elsewhere, as the motor is rated only for 230 V AC.
16 W shaded-pole output at 550 RPM
The 16 watt rated output at 550 RPM is the decisive figure for matching the motor to the driven load. If the nameplate on the failed unit shows a different horsepower, wattage or speed, this model will not deliver the required airflow or torque.

Questions about this item
Does the FASCO UB568 unit bearing motor include mounting hardware or a fan blade?
The motor has a rear double-foot mounting design and a CWLE shaft rotation; mounting bolts and a fan blade are not included and must be sourced separately.
Should I choose the 230 V AC single-speed version or look for a multi-speed alternative?
This model is a single-speed shaded-pole motor rated for 230 V AC at 60 Hz and is not usable at 208 V or 200 V, so select it only if your system matches those exact electrical requirements.
What does the 550 RPM nameplate speed mean for airflow in my HVAC unit?
At 550 RPM the motor delivers 16 W output with a 1.0 service factor and continuous duty rating, providing the low-speed torque needed for direct-drive fan applications in a 40 °C maximum ambient.
