Dayton 31TU30 3 HP 143-5TC/56HCZ Frame hvac control

SKU CH-XDYH-ZHSTB

Three-phase general-purpose motor converts electrical energy into mechanical power for industrial and HVAC machinery

  • 3 HP motor drives demanding HVAC equipment
  • Three-phase design delivers efficient continuous power
  • 143-5TC/56HCZ frame fits standard mounting points
  • CC060A identifier simplifies service and replacement tracking
  • Continuous duty cycle supports non-stop operation

Three-Phase Motor for Industrial HVAC

The Dayton 31TU30 is a three-phase AC motor rated at 3 HP and built on a 143-5TC/56HCZ frame. It converts electrical energy into mechanical rotation for power-transmission and pneumatics tasks. The unit carries EASA CC number CC060A for design tracking. It suits maintenance teams and OEMs specifying a standard-frame general-purpose motor.

Continuous Duty with Defined Frame Limits

The motor carries a continuous duty rating so it can run without scheduled rest periods within its nameplate limits. Output tops out at 3 HP, so loads demanding higher torque or speed will exceed its capacity. The 143-5TC/56HCZ frame fixes the mounting footprint and shaft dimensions, restricting direct replacement to matching frame sizes.

Direct-Couple Integration in Existing Lines

The fixed frame and shaft allow direct coupling to gearboxes, pumps or fans that share the 143-5TC/56HCZ pattern. No adapter plates or custom bases are needed when the driven equipment matches this frame. Installers must supply their own three-phase supply, starter and overload protection because the motor ships as a bare rotating unit.

Questions about this item

Will the 143-5TC/56HCZ frame match the mounting pattern on my existing 56-frame motor?

The 143-5TC/56HCZ frame combines the bolt pattern of a 143-5TC motor with the shaft dimensions of a 56HCZ motor, so it fits both mounting styles.

How can I verify the motor is running correctly after wiring it for three-phase power?

Confirm the motor starts smoothly, runs continuously without overheating, and draws balanced current on all three phases under load.

Does the box include a mounting base or coupling, or must I supply them?

The motor ships as the frame and windings only; mounting base, coupling, and wiring accessories are purchased separately.
