Unit Bearing Motor for HVAC Controls

The Dayton 4YFJ4 is a shaded-pole motor rated at 1/185 hp and 230V AC for HVAC control applications. It delivers a nameplate speed of 550 rpm with 4 watts of output power. The totally enclosed air-over design suits horizontal or vertical shaft-up mounting. A cast aluminium frame houses the rear-foot mounting arrangement.

230V AC Single-Phase Power Requirement

This motor operates on 230V AC at 50/60 Hz and draws 0.17 A at full load. The single-phase shaded-pole design needs no external capacitor or starter. Impedance thermal protection and Class A insulation handle ambient temperatures up to 40 degrees C. Verify that the supply matches these exact voltage and frequency values before installation.

Rear-Foot Mount with Fixed CWLE Rotation

The rear-foot cast aluminium frame bolts directly to compatible HVAC housings. Rotation is fixed clockwise from the lead end, so the driven fan or blower must match this direction. The non-standard frame means dimensions differ from common NEMA sizes; confirm bolt pattern and shaft fit against the original equipment. No alternative mounting positions or rotation options are available.

Questions about this item

What does the 1/185 hp rating mean for airflow in a real HVAC unit?

The 1/185 hp output delivers 4 watts at 1,550 RPM, suitable for small direct-drive fan or blower wheels in residential HVAC equipment.

How does the 230V AC, 60/50 Hz supply affect motor performance?

The shaded-pole design runs at nameplate speed on both 60 Hz and 50 Hz mains, drawing 0.17 A full-load current at 230 V AC.

What clearance and orientation does the rear-foot, cast-aluminium frame require?

The motor mounts horizontally or with the shaft vertical-up on its rear foot pattern; the totally enclosed air-over body needs surrounding airflow and fits within a 40 °C maximum ambient.
