What the UB592 unit bearing motor does
The FASCO UB592 is a shaded-pole unit bearing motor rated at 1/200 hp and 115 V AC. It delivers 550 RPM at 5 W output with a continuous duty cycle. The motor suits HVAC controls that need a compact, single-speed drive in a totally enclosed air-over enclosure.
Installing the motor and common pitfalls
Mount the motor using its rear double-foot pattern and confirm the shaft rotates clockwise from the lead end. Wire the single-phase supply to 115 V AC, 60 Hz, drawing 0.34 A at full load; the motor is not usable at 200 V or 208 V. Impedance thermal protection and Class B insulation handle normal heat, but the 40 °C ambient limit must be observed.
Limits of the shaded-pole design
Shaded-pole construction provides only one fixed speed and low starting torque, so the motor cannot drive variable-speed loads or high-inertia fans. The 5 W output restricts it to small air-moving tasks, and the non-standard frame may not match common mounting bolt patterns without an adapter.

Questions about this item
How can I confirm the motor is running correctly after installation?
The motor should rotate clockwise from the lead end at 550 RPM while drawing 0.34 A at 115V AC; continuous operation up to 40 °C ambient is within specification.
What comes with the FASCO UB592 and what must I source separately?
The unit bearing motor itself is supplied; mounting hardware, wiring connectors and any fan blade or driven component are not included and must be purchased separately.
Which voltage and horsepower version of the UB592 should I select for a 115 V shaded-pole application?
Choose the 1/200 hp, 115 V AC, single-speed model rated at 550 RPM and 0.34 A full-load current; it is not usable at 200 V or 208 V.
