Dayton 6XH73 Split Phase Motor 1/4 HP 850 RPM 56 Frame

SKU CH-TNJJ-0WAPN

General-purpose split-phase motor delivers 1/4 hp at 850 rpm in a 56 frame for continuous HVAC duty

  • 1/4 HP output drives light-duty HVAC equipment
  • 850 RPM single-speed suits fan and blower applications
  • 115 V AC supply matches standard residential circuits
  • 56 frame with cradle base fits common mounting patterns
  • Continuous duty with 1.25 service factor handles sustained loads

Product Identity

The Dayton 6XH73 is a split-phase AC motor rated at 1/4 horsepower and 850 RPM. It is built for continuous-duty HVAC applications where a single-speed, open drip-proof enclosure is specified. The 56 frame and cradle-base mounting suit standard industrial footprints.

Capacity and Headroom

The motor delivers 1/4 hp at a service factor of 1.25, drawing 6.9 A at 115 V AC. This headroom covers typical fan and blower loads within the nameplate rating. Operation beyond the 40 °C ambient limit or sustained overload will exceed the design margin.

Interface Limits

The 115 V, 60 Hz single-phase supply and split-phase starting define the electrical boundary. No thermal protection is fitted, so external overload provision is required. The keyed shaft and CW/CCW rotation accommodate direct drive, but the ODP enclosure restricts use to clean, dry indoor locations.

Questions about this item

Will the 56 frame and keyed shaft match the mounting brackets and coupling on my existing 115 V blower assembly?

The motor uses a standard NEMA 56 frame with a cradle base and a keyed shaft, so it bolts to existing 56-frame brackets and accepts the same coupling or pulley you currently use.

How can I confirm the 850 RPM single-speed motor is running correctly after installation?

Measure the shaft speed with a tachometer; it should read approximately 850 RPM under load at 115 V and 60 Hz, and the current draw should be near the 6.9 A nameplate value.

Does the open drip-proof motor ship with a capacitor, start switch or mounting hardware, or must I source those separately?

As a split-phase design it has no capacitor or start switch; the box contains only the motor with its cradle base, so mounting bolts and any drive components must be supplied separately.
