  • 230 V AC operation matches standard HVAC supply
  • Totally enclosed air-over design protects windings in 40 °C ambients

HVAC Unit Bearing Motor 1/100 HP

The FASCO UB599 is a shaded-pole unit bearing motor rated at 1/100 HP for 230 V AC single-phase supply. It delivers 9 W output at 1,550 RPM with a clockwise shaft rotation when viewed from the lead end. The motor carries automatic thermal protection and Class B insulation for continuous duty in HVAC control applications.

Shaded-pole single-phase limits

Shaded-pole designs provide fixed-speed operation at 60 Hz with no provision for speed control or reversible rotation. The motor is not usable at 208 V or 200 V and requires a 230 V supply drawing 0.27 A full-load current. Ambient temperature must not exceed 40 °C and the totally enclosed air-over enclosure depends on external airflow for cooling.

Rear double-foot mounting constraint

Installation requires a rear double-foot mounting pattern that matches the non-standard frame of this unit. Builders whose equipment uses a different foot spacing or a resilient-ring mount cannot use this motor without fabricating an adapter bracket.

Questions about this item

Which version of the FASCO UB599 unit bearing motor should I choose for my HVAC system?

The FASCO UB599 is offered as a single configuration: a shaded-pole motor rated at 1/100 HP, 230 V AC, 0.27 A full-load current, 1,550 RPM, clockwise rotation, and a non-standard frame with rear double-foot mounting.

What does the 1/100 HP rating mean once the motor is installed in my equipment?

At 1/100 HP the motor delivers approximately 9 W of mechanical output, suitable for light-duty air-over applications such as small fan or blower wheels in residential HVAC controls.

What voltage standard does the UB599 use and what does that limit in practice?

The motor is designed for 230 V AC, 60 Hz single-phase supply and is not usable at 208 V or 200 V, so it must be connected to a true 230 V circuit.
