Dayton 5C040 Oscillating Fan Motor 1/2 hp HVAC Control

SKU CH-DPC9-XQR5J

Oscillating fan motor delivers 1/2 hp at 115 V AC with two-speed operation at 1075 and 875 RPM in a 48YZ frame

  • ColorTransparent
  • 1/2 hp motor powers demanding HVAC airflow
  • Two-speed operation at 1075 and 875 RPM matches load needs
  • 115 V single-phase supply fits standard building wiring
  • Totally enclosed air-over design protects windings in dusty environments
  • Auto thermal protection and Class B insulation extend motor life

1/2 hp Oscillating Fan Motor

The Dayton 5C040 is a single-phase oscillating fan motor rated at 1/2 hp for HVAC control applications. It operates on 115V AC at 60 Hz with a 48YZ frame and draws 4.5 A at full load. The permanent split capacitor design provides two-speed operation at 1,075 and 875 RPM. Automatic thermal protection and Class B insulation support continuous duty cycles.

Horizontal mount with 5/8 in shaft

This motor mounts horizontally in a totally enclosed air-over enclosure with a 3 1/16 in shaft length and 5/8 in shaft diameter. Clockwise rotation when viewed from the shaft end suits direct-drive fan assemblies. The 1.0 service factor and 40 degrees C maximum ambient temperature define the operating envelope. Installers must provide a compatible capacitor and verify voltage supply matches the 115V AC requirement.

HVAC technicians replacing direct-drive fan motors

This unit suits technicians servicing oscillating fan systems that require a 48YZ frame motor with horizontal mounting and CWSE rotation. It does not suit applications needing vertical mounting, reversible rotation or a different frame size. Buyers who need variable-speed control beyond the two fixed speeds or a higher horsepower rating should look at alternative motor configurations.

Questions about this item

What limits how long the motor can run continuously at 40 °C ambient?

The motor is rated for continuous duty at up to 40 °C ambient with Class B insulation and automatic thermal protection.

How much noise and heat should I expect when the motor runs all day on 115 V AC?

It draws 4.5 A full-load amps on 115 V AC; the totally enclosed air-over enclosure relies on the airstream it creates to carry heat away.

What mounting and shaft details must my fan assembly already provide?

Horizontal mounting, 48YZ frame, 5/8 in shaft diameter and 3 1/16 in shaft length with clockwise rotation viewed from the shaft end.
