HVAC Blower Motor 1/3 HP
This Dayton 3M713 blower motor is a permanent split capacitor unit rated at one-third horsepower for continuous-duty HVAC applications. It operates on 277 volt single-phase power at 60 hertz and draws 2.2 amps at full load, making it suitable for commercial air-handling equipment that requires reliable airflow.
48YZ Frame Stud Mount Open Air Over
The motor uses a 48YZ frame with a half-inch diameter shaft extending six inches and a stud mounting pattern that allows all-angle installation. Its open air-over enclosure relies on the airstream for cooling, while automatic thermal protection and Class B insulation guard against overheating up to a maximum ambient temperature of 40 degrees Celsius.
Replaces Worn Direct-Drive Blower Motors
This unit replaces failed direct-drive blower motors in furnaces, air handlers or packaged rooftop units where the original spec matches 1075 RPM three-speed operation at 277 volts. The jump is worth it when the existing motor has seized bearings, weakened windings or a tripped thermal protector that can no longer sustain continuous duty.
Highlights
- PSC motor runs efficiently at 1/3 HP
- Three-speed operation matches airflow needs
- 277 V supply suits commercial systems
- Auto thermal protection prevents overheating
- 48YZ frame with 1/2 in shaft fits standard mounts

Questions about this item
What does the 277 V AC rating mean for circuit compatibility?
The motor runs on a 277 V AC single-phase supply at 60 Hz and draws 2.2 A at full load, so the branch circuit and breaker must be rated for that voltage and current.
Will the 48YZ frame with 1/2 in shaft and 6 in shaft length fit my existing mount?
The 48YZ frame uses stud mounting in any angle; the shaft is 1/2 in diameter and 6 in long, so match those dimensions to your fan hub and mounting studs.
How do I wire the three-speed PSC motor correctly?
Connect the 277 V line to the common and desired speed tap, install the required run capacitor per the wiring diagram, and verify rotation is CW or CCW as needed.
