Dayton 31TT12 three-phase motor
The Dayton 31TT12 is a general-purpose three-phase AC motor rated at 1 HP in a standard 56 frame. It converts electrical energy into mechanical rotation for industrial and commercial machinery, including HVAC systems. Continuous duty design allows sustained operation under specified conditions. Energy Aware certification confirms it meets recognised environmental and energy-efficiency criteria.
230/460 V dual-voltage operation
Dual-voltage windings accept 230 V or 460 V three-phase supply, drawing 3.0 A at the lower voltage and 1.5 A at the higher voltage. Continuous duty rating means the motor handles full-load current without time limitation when properly cooled and protected. Headroom ends at the nameplate horsepower; loads exceeding 1 HP or frequent starts beyond the duty cycle will overheat the windings.
Replaces worn 56-frame three-phase units
This motor serves as a direct drop-in replacement for failed or ageing 56-frame three-phase motors of the same horsepower and voltage. The jump is worthwhile when the existing unit shows bearing noise, insulation breakdown or repeated thermal trips. It is not suited for single-phase supplies, variable-frequency drives without inverter-rated insulation, or applications requiring a different frame size or power rating.

Questions about this item
Will the 56-frame three-phase motor fit the mounting pattern on my existing 56-frame equipment?
Yes — the 56 frame conforms to standard NEMA dimensions, so it bolts directly to any 56-frame mounting surface without adapters.
How can I verify the 1 HP three-phase motor is drawing the correct current after wiring it for 230 V?
Measure the supply lines with a clamp meter; at full load you should see approximately 3.0 A on each phase when connected for 230 V operation.
Does the 31TT12 ship with a mounting base, conduit box or wiring accessories, or must they be ordered separately?
The motor is supplied as the bare unit only; mounting base, conduit box, cable glands and any required wiring accessories are sold separately.
