What this motor does

The Dayton 4YFG9 is a shaded-pole unit bearing motor rated at 1/185 HP and 1,550 rpm for 115 V AC operation. It delivers 4 W output and is built for HVAC control applications such as fan or damper drives.

Check voltage, mounting and rotation

Confirm your system supplies 115 V AC at 50 or 60 Hz and can accommodate a rear-foot mount with a horizontal or vertical shaft-up orientation. The shaft rotates CCWLE and the totally enclosed air-over enclosure requires airflow for cooling.

Replaces worn shaded-pole motors

This unit replaces failed shaded-pole motors of the same horsepower, speed, voltage and rotation in HVAC equipment. The jump is worth it when the original motor has lost torque, overheats or shows bearing noise and a direct drop-in with identical electrical and mechanical specs is needed.
