Pedestal Fan Motor 1/2 HP 1075 RPM
This Dayton 3M505 motor delivers 1/2 horsepower at a nameplate speed of 1,075 RPM. It operates on 115V AC single-phase power at 60 Hz with a 48YZ frame. The unit is designed for continuous duty cycles in HVAC applications.
Permanent Split Capacitor Two-Speed Design
The permanent split capacitor design provides two-speed operation for adjustable airflow control. Automatic thermal protection safeguards the motor during overload conditions. Class B insulation supports a maximum ambient temperature of 40 degrees Celsius.
Horizontal Mounting 5/8 Inch Shaft
Verify that your equipment requires a horizontal mounting position with a 5/8 inch diameter shaft measuring 2 1/2 inches long. Confirm the 48YZ frame dimensions match the existing mounting pattern. Ensure the 7.2 amp full-load current is compatible with your circuit protection.

Questions about this item
Will the thermal protection on this 1/2 HP motor need resetting or replacement after repeated trips?
The motor uses automatic thermal protection, so it resets itself once the temperature drops below the limit. No manual reset or replacement of the protector is required under normal operation.
What limits continuous running at full 7.2 A load in a 40 °C ambient?
The insulation is Class B and the service factor is 1.0, so the winding temperature rise at rated load in 40 °C ambient is the limiting factor for continuous duty.
How much heat and noise should I expect from the totally enclosed air-over enclosure during all-day operation?
The totally enclosed air-over design relies on the fan's own airflow for cooling, so the motor surface will run warm but within Class B limits, and noise is limited to bearing and air-movement sound at 1,075 RPM.
