Dayton 6GC94 3/4hp Direct Drive Blower Motor

SKU CH-9HHE-871DR

Direct-drive blower motor delivers 3/4 hp at 1,075 rpm with three-speed operation on 277 V AC

  • 3/4 HP delivers strong airflow for HVAC systems
  • Permanent split capacitor design ensures efficient single-phase operation
  • Three-speed settings allow adjustable airflow control
  • 277 V AC rating suits commercial building wiring
  • Auto thermal protection prevents overheating during continuous duty

Direct-Drive Blower Motor

The Dayton 6GC94 is a single-phase permanent split capacitor motor rated at 3/4 hp for direct-drive blower applications. It runs on 277 V AC at 60 Hz and draws 4.1 A at full load. The 48YZ frame mounts via ring or stud in any orientation. Auto thermal protection and Class B insulation support continuous duty in ambient temperatures up to 40 °C.

HVAC Replacement and OEM Builds

This motor suits technicians replacing a failed direct-drive blower unit or OEMs specifying a three-speed 277 V motor for air-over cooling. It is not for installers who need a different voltage, a higher horsepower rating, or an enclosed frame for dirty environments. Buyers requiring a belt-drive configuration or a different frame size should look at other options.

Verify Voltage and Mounting Compatibility

Confirm the supply is 277 V AC single-phase at 60 Hz before ordering. Check that the existing mounting pattern matches the 48YZ ring/stud arrangement and that the shaft rotation direction can be set to CW or CCW as required. Ensure the ambient temperature at the install site will not exceed 40 °C for continuous operation.

Questions about this item

Does my HVAC unit need a 48YZ frame opening and a 277 V single-phase supply to install this 3/4 hp blower motor?

Yes, the motor is built for a 48YZ frame and runs on 277 V AC single-phase power, so the equipment must match both.

Can I keep my existing run capacitor when swapping to this permanent-split-capacitor motor?

The motor uses a permanent-split-capacitor design, so a compatible run capacitor must stay in the circuit for proper operation.

How do I confirm the motor is running correctly after wiring it for CW or CCW rotation?

Verify the shaft turns in the selected direction, reaches the 1,075 RPM nameplate speed, and draws no more than 4.1 A under full load.
