Purpose and fit
The Dayton 4YFJ7 is a shaded-pole unit bearing motor rated at 1/83 hp for HVAC control applications. It runs on 115V AC single-phase power at 60/50 Hz and draws 0.62 A at full load. The motor delivers 9 W output at a nameplate speed of 550 rpm with clockwise rotation viewed from the lead end.
Build integration
A cast aluminium frame and totally enclosed air-over enclosure allow horizontal or vertical shaft-up mounting via rear foot brackets. The non-standard frame requires a matching mounting pattern and shaft coupling in the host equipment. Thermal protection is automatic and the insulation is rated Class A for a maximum ambient temperature of 40 degrees C.
Sustained operation
Continuous duty is supported by the auto-reset thermal protector and the service factor of 1 at the rated load. The low-speed shaded-pole design limits starting torque, so the motor suits fan or blower loads that accelerate gradually. Heat dissipation relies on airflow over the enclosed body, making unobstructed ventilation necessary during extended runs.

Questions about this item
At what ambient temperature does the motor reach its thermal limit under sustained use?
The motor is rated for a maximum ambient temperature of 40 degrees C.
How much heat and noise should I expect from the 9 W shaded-pole motor running continuously?
The totally enclosed air-over design dissipates 9 watts of output power with auto thermal protection and Class A insulation.
Does the rear-foot mounting on the cast-aluminium frame require any special brackets to install?
The motor uses a rear/foot mounting type on a non-standard frame; verify the mounting pattern matches your equipment.
