Dayton 4YFJ5 HVAC Control Unit Bearing Motor 1/185 hp 230V AC
Single-phase shaded-pole unit-bearing motor delivers 1/185 hp at 230V AC for HVAC control applications
- ColorTransparent
- Reliable HVAC control with 1/185 hp shaded-pole motor
- Runs on standard 230V AC single-phase power
- Low 0.17 A draw keeps energy use minimal
- Impedance thermal protection guards against overheating
- Cast-aluminium frame suits horizontal or vertical shaft-up mounting
Application Fit
This unit bearing motor is built for HVAC control systems that require a shaded-pole, single-phase drive. It operates on 230V AC at 60/50 Hz and delivers 1/185 hp with a nameplate speed of 1,550 RPM. The cast-aluminium frame and totally enclosed air-over enclosure suit indoor equipment where ambient temperatures reach 40 °C.
Build Integration
The rear-foot mounting and non-standard frame mean the motor bolts directly to the equipment chassis without an adapter bracket. Its horizontal or vertical shaft-up orientation gives layout flexibility inside cabinets. Impedance thermal protection and Class A insulation handle continuous duty at 0.17 A full-load current, freeing the designer from adding external overload devices.
Sustained Operation
Rated for continuous service with a 1.0 service factor, the motor maintains its 4 W output without derating during extended runs. Shaded-pole construction provides inherent simplicity — no capacitors or starting switches to age — so reliability stays consistent over long operating periods. The CCWLE shaft rotation is fixed, so the driven load must match that direction.

Questions about this item
At what ambient temperature does the motor reach its thermal limit during continuous operation?
The motor is rated for a maximum ambient temperature of 40 degrees Celsius, beyond which its impedance protection may trip.
How much current does the motor draw and what noise or heat should be expected when running all day?
It draws 0.17 A at 230 V AC, producing 4 W of output in a totally enclosed air-over frame that runs warm but stays within Class A insulation limits.
What voltage supply and mounting arrangement must already be in place for this motor to operate?
A 230 V AC single-phase supply at 50 or 60 Hz and a rear or foot mounting surface suited to the non-standard cast-aluminium frame are required.
