FASCO UB590 Unit Bearing Motor 1/250 HP 230V CW 0.14 A
A 1/250 HP shaded-pole unit bearing motor running at 450 RPM on 230 V AC with CW rotation and continuous duty
- ColorTransparent
- Reliable continuous operation with 40 °C ambient rating
- Shaded-pole design delivers 4 W output at 1/250 HP
- Single-speed 1,450 RPM simplicity for consistent airflow
- 230 V AC supply with 0.14 A full-load current
- Totally enclosed air-over enclosure protects motor internals
Purpose & Audience
The FASCO UB590 is a shaded-pole unit bearing motor rated at 1/250 HP for 230 V AC single-phase supply. It delivers 4 W output at 1,450 RPM with a continuous duty cycle and impedance thermal protection. The clockwise lead-end rotation suits direct-drive fan or blower wheels in HVAC equipment. Buyers needing reversible rotation or higher starting torque should look elsewhere.
Build Integration
The motor fits a non-standard rear/double-foot mounting pattern and a totally enclosed air-over enclosure rated for 40 °C maximum ambient. It draws 0.14 A full-load current at 60 Hz and is not usable at 208 V or 200 V. The single-speed design eliminates speed-control wiring but requires the driven load to match the fixed 1,450 RPM shaft speed.
Included Extras
The unit ships as the motor only; no capacitor, mounting hardware, wiring harness or speed controller is bundled. Installers must supply compatible foot fasteners, electrical connections and any required overload protection separately.

Questions about this item
What is the maximum ambient temperature this motor can handle during continuous operation?
The motor is rated for a maximum ambient temperature of 40 degrees Celsius with a continuous duty cycle.
Does the motor run hot or draw more power when operated at its rated 230V AC for extended periods?
It draws 0.14 amps full load at 230V AC, features impedance thermal protection, and is designed for continuous duty.
What voltage supply is required since it cannot operate on 200V or 208V?
This unit requires a 230V AC, 60 Hz power supply and is not usable at 200V or 208V.
