Motor Type and Rating
This Dayton 4UX68 is a single-phase split-phase motor rated at 1/3 hp and 1,725 RPM. It runs on 115 V AC at 60 Hz and draws 4.8 A at full load. The unit suits HVAC equipment that requires a horizontal, open air-over motor in a 48YZ frame.
Thermals and Power Draw
Continuous duty is supported with automatic thermal protection and Class B insulation. The maximum ambient temperature is 40 °C and the service factor is 1.0. An open air-over enclosure allows airflow to manage heat during normal operation.
Shaft and Mounting Details
A 5/8 in diameter shaft extends 2 in and rotates in either direction. The horizontal mounting position and 48YZ frame dimensions determine fitment in compatible pedestal fan assemblies. No additional accessories or software are included with this motor.

Questions about this item
How is the 48YZ-frame motor mounted horizontally and what step is often missed?
Mount the motor horizontally on its 48YZ frame using the 5/8-inch shaft; the step often missed is confirming clockwise or counter-clockwise rotation before tightening the set screw.
What maintenance will the split-phase motor need during continuous duty?
The open air-over enclosure requires periodic cleaning of dust from the windings; the automatic thermal protection resets itself, but the Class B insulation should be inspected if the 40 °C ambient limit is regularly reached.
What limit appears first when the motor runs continuously at 1725 RPM?
The 40 °C maximum ambient temperature is the first limit reached; exceeding it trips the automatic thermal protection and stops the motor until it cools.
