Dayton

Dayton Definite Purpose HVAC Motor 1/2 hp 120V 825 RPM

SKU CH-EVSR-9ST7B

Single-phase PSC motor delivers 1/2 hp at 825 RPM on 120 V AC with 5.3 A full-load current, Class B insulation rated for 40 °C ambient, continuous duty in a horizontal steel frame

  • 1/2 hp output drives HVAC equipment reliably
  • Permanent split capacitor design provides efficient single-phase operation
  • 825 RPM at 120 V AC matches OEM replacement specs
  • Continuous duty rated for 40 °C maximum ambient temperature
  • Horizontal steel frame mounting suits definite-purpose installations

HVAC Motor for Continuous Duty

The Dayton definite-purpose HVAC motor delivers 1/2 horsepower at 825 RPM on a 120 V AC single-phase supply. Its permanent split capacitor design suits continuous operation in heating, ventilation and air-conditioning equipment. A maximum ambient temperature of 40 °C and Class B insulation support reliable long-term running.

Voltage Compatibility Limits

This motor is rated for 120 V and is not usable at 200 V or 208 V. The jump to a higher-voltage supply is not worth it because the windings and insulation are not rated for those levels. Full-load current is 5.3 A at the nominal voltage, so installers must stay on the specified 120 V circuit.

Mounting and Frame Constraints

The unit uses a non-standard steel frame built for horizontal mounting only. Vertical or angled installation is not supported by the frame design. Operators should verify that the driven equipment matches the 60 Hz nameplate speed and that the mounting orientation remains horizontal throughout the duty cycle.

Questions about this item

What frame size and mounting orientation does this 1/2 hp motor require?

The motor uses a non-standard steel frame and must be mounted horizontally; verify the existing housing dimensions before ordering.

How do I wire the permanent split capacitor on this 120 V unit?

Connect the 120 V supply to the designated line leads and attach the run capacitor across the capacitor terminals; reversing the capacitor leads is the common error.

When should I plan to replace the bearings on this continuous-duty HVAC motor?

With Class B insulation rated for 40 °C ambient and continuous duty, bearings typically last several years; inspect annually for noise or heat and replace if worn.
