Dayton 6XH78 HVAC Control Motor 1/6HP 1140RPM 115V

SKU CH-1C88-EBMWJ

Single-phase split-phase motor delivers 1/6 hp at 1140 rpm on 115 V AC for continuous HVAC duty

  • Reliable HVAC operation from a 1/6 HP split-phase motor
  • Continuous-duty design handles 40 °C ambient temperatures
  • 35 service factor provides extra torque margin
  • Reversible CW/CCW rotation suits varied installations
  • Open drip-proof steel frame resists moisture ingress

Motor Specifications

The Dayton 6XH78 is a general-purpose split-phase motor rated at 1/6 hp and 1,140 RPM for 115 V AC single-phase supply. It suits HVAC control applications that need continuous-duty operation in ambient temperatures up to 40 °C.

Upgrade Context

This unit replaces an existing 48Z-frame motor with matching voltage, speed and shaft configuration when the original fails or lacks the 1.35 service factor. The jump is worth it if the old motor runs hot, lacks reversible rotation or cannot handle the 4.5 A full-load current.

Build Integration

The open drip-proof steel frame with cradle-base mounting fits standard HVAC housings, while the flat shaft accepts common drive components. Class B insulation and reversible CW/CCW rotation simplify wiring, though the absence of thermal protection means the installer must provide external overload safeguards.

Questions about this item

What frame size and mounting type does the 6XH78 motor use?

The motor uses a 48Z frame with a cradle base mounting type, so the mounting surface must match those dimensions.

How do I wire the 115 V split-phase motor for the correct rotation?

Connect the 115 V AC supply to the two power leads; swap the leads to reverse the CW/CCW rotation.

When should I expect to replace the bearings on this open drip-proof motor?

With continuous duty at 40 °C max ambient and no thermal protection, plan bearing inspection annually and replace if noise or play appears.
