FASCO UB569 Unit Bearing Motor 1/50 HP 230V 550 RPM

SKU CH-M0SY-9ETQJ

Unit bearing motor UB569 delivers 1/50 HP at 550 RPM on 230 V AC for continuous HVAC duty

  • ColorTransparent
  • 1/50 HP shaded-pole motor delivers 16 W continuous output
  • 550 RPM single-speed operation suits low-speed HVAC applications
  • 230 V AC at 0.4 A full-load current simplifies wiring
  • Totally enclosed air-over enclosure protects windings in 40 °C ambient
  • Rear double-foot mounting with CCWLE rotation enables direct replacement

Application & User

The FASCO UB569 is a shaded-pole unit bearing motor rated at 1/50 HP for 230 V AC single-phase supply. It delivers 16 W output at 550 RPM with a continuous duty cycle and automatic thermal protection. Technicians servicing HVAC controls that require a compact, direct-drive motor with a rear double-foot mount will find this unit matches the original specification.

Replacement Scope

This motor replaces an existing shaded-pole unit bearing motor of the same horsepower, voltage, speed and CCWLE rotation. The upgrade is justified when the original motor has failed thermally or mechanically and the mounting footprint, shaft orientation and 0.4 A full-load current remain unchanged. It is not suited for applications that demand multi-speed operation, higher starting torque or operation at 208 V or 200 V.

Interface Limits

The totally enclosed air-over enclosure requires airflow across the motor body for cooling and is rated for a maximum ambient temperature of 40 °C. Operation is limited to 60 Hz supply frequency and the fixed 550 RPM nameplate speed. The non-standard frame and rear double-foot mounting pattern restrict interchangeability to equipment designed for this exact footprint.

Questions about this item

What mounting pattern does the UB569 rear double-foot design use?

The motor mounts with a rear double-foot arrangement; verify the bolt-hole spacing on your bracket matches the frame before installation.

Which wiring step causes the most errors when fitting this shaded-pole motor?

Connect the single-phase 230 V AC supply to the two leads only; the auto thermal protector is internal, so adding an external overload is a common mistake.

When should the sleeve bearing in this unit-bearing motor be inspected?

Inspect the bearing at each seasonal HVAC service; the 40 °C max ambient and continuous duty cycle mean lubrication loss is the typical wear-out mode.
