Dayton Pedestal Fan Motor 1/4 HP 115V 9-1/4in.L GGS_47305

SKU CH-87HG-PDS9M

Replacement pedestal-fan motor delivering 1/4 HP at 115 V with a 3-inch, 1/2-inch-diameter shaft and yoke mounting

  • weight17.7
  • Quarter-horsepower motor drives pedestal fans reliably
  • Single-phase PSC design runs on standard 115V AC power
  • Two-speed operation with automatic thermal protection
  • 48YZ frame fits common yoke-mount installations
  • Continuous-duty rating at 60 Hz for steady airflow

Motor Purpose & Fit

The Dayton pedestal fan motor replaces a worn or failed unit in an existing pedestal fan assembly. It supplies 1/4 HP at 115 V AC single phase for continuous duty. The permanent split capacitor design provides two-speed operation at a nameplate speed of 1,100 RPM. Buyers who need a different voltage, phase count or horsepower rating cannot use this motor.

Build Integration

The motor uses a 48YZ frame with a yoke mounting style and a 1/2 inch diameter shaft extending 3 inches. It draws 2.00 full-load amps at 60 Hz and weighs 17.7 units. The totally enclosed air-over enclosure protects windings while relying on the fan's airflow for cooling. Installers must verify that the original fan housing accepts the yoke mount and shaft dimensions before ordering.

Sustained Operation

Thermal protection is automatic and the insulation class B rating supports continuous duty cycles without shutdown. The service factor of 1 indicates the motor runs at its nameplate load without overload margin. Rotation is fixed clockwise when viewed from the shaft end, so the fan blade must match that direction. The motor maintains its rated output as long as the surrounding air stream provides adequate cooling.

Questions about this item

How long can the 1/4 HP motor run at its 100 RPM nameplate speed without stopping?

The motor carries a continuous duty cycle rating, so it is designed to run all day at 100 RPM without a mandated rest period.

How much current does the 115 V motor draw when it runs continuously?

At full load it pulls 2.00 amps on a 115 V AC, 60 Hz supply, so plan the circuit for that steady draw.

What shaft dimensions must the existing fan blade or hub match to fit this motor?

The motor shaft is 3 in long and 1/2 in diameter, so the blade or hub must accept that exact shaft size.
