Product Identity

The Dayton 4YFJ9 is a unit bearing motor rated at 1/83 hp for 230 V AC operation at 550 RPM. It suits technicians replacing shaded-pole motors in HVAC air-over applications where a totally enclosed, cast-aluminium frame is required.

Electrical And Thermal Limits

The motor draws 0.33 A at full load and delivers 9 W output at 50 or 60 Hz. Insulation class A and automatic thermal protection cap the maximum ambient temperature at 40 °C, so the installation must stay within that thermal envelope.

Installation Checks

Verify that the driven load matches the clockwise lead-end rotation and that the rear or foot mounting pattern fits the existing bracket. Confirm the supply is single-phase 230 V AC and that the non-standard frame dimensions align with the available space before ordering.

Questions about this item

How do I choose between the 50 Hz and 60 Hz ratings on this motor?

The motor is rated for both 50 and 60 Hz operation, so it will run on either supply frequency without a separate version to select.

What does the 1/83 hp rating mean for actual airflow in my HVAC unit?

At 1/83 hp and 9 W output, the motor delivers low torque suited for small direct-drive fans or blower wheels in residential HVAC equipment.

Will the 230 V AC shaded-pole design limit the speed I can run this motor at?

Yes, the shaded-pole design and 550 RPM nameplate speed are fixed by the 230 V AC supply frequency; the motor cannot be speed-controlled with a standard voltage reducer.
