Industrial Three-Phase Motor
The Dayton 2NKY3 is a three-phase general-purpose motor rated at 2 HP for industrial and commercial machinery. It converts electrical energy into mechanical power for manufacturing lines, HVAC systems and other fixed equipment. The 143-5T/56HZ frame follows standard dimensions for mounting compatibility. Buyers needing single-phase input or a different horsepower rating should look elsewhere.
Continuous Duty Electrical Profile
Designed for continuous duty cycle operation, the motor draws 5.7 A at the lower voltage and 2.8 A at the higher voltage when running at full load. The CC030A identifier from EASA classifies the design for performance and efficiency expectations. No sound-pressure or thermal-rise figures are supplied, so installers must rely on application-specific testing. The Proposition 65 notice flags chemicals known to California to cause cancer and reproductive harm.
Frame Mounting and Wiring Considerations
The standard 143-5T/56HZ frame allows direct replacement in many existing mounts without re-drilling. Three-phase supply wiring and appropriate overload protection are required before commissioning. No starter, capacitor, VFD or coupling is included, so those components must be sourced separately. The motor does not ship with a power cord, plug or integrated controls.

Questions about this item
How do I mount the 143-5T/56HZ frame motor and align the shaft?
Bolt the motor to a rigid base using the standard 143-5T/56HZ mounting holes, then align the shaft to the driven load within the manufacturer's angular and offset tolerances before tightening the coupling.
What bearing maintenance does the 2 HP three-phase motor require?
Relubricate the bearings at intervals recommended by Dayton for continuous-duty operation, using the specified grease type and quantity to avoid premature wear.
At what current does the thermal overload trip during sustained full-load running?
The motor draws 5.7 A at full load on the low-voltage connection and 2.8 A on the high-voltage connection; size the overload relay to the corresponding full-load amp value.
