Dayton 4YFH3 unit bearing motor
This single-phase shaded-pole motor delivers 1/83 hp at 1,550 rpm on 115 V AC. It draws 0.62 A at full load and produces 9 W output. The totally enclosed air-over design suits HVAC control duties where quiet, continuous operation is required.
Check voltage, shaft and mounting
Verify the supply is 115 V AC at 50 or 60 Hz. The 1/2 in. shaft rotates clockwise viewed from the lead end and uses a rear/foot mount on a cast-iron frame. Ensure the application tolerates a maximum ambient temperature of 40 °C and Class A insulation.
Replaces worn shaded-pole unit bearing motors
The motor is a direct swap for failed 1/83 hp shaded-pole units in fan-coil, ventilation or refrigeration controls. The upgrade is worthwhile when the original motor shows bearing noise, overheating or reduced airflow. It is not suited for applications demanding higher torque, variable speed or three-phase power.
