General-purpose three-phase motor
The Dayton 2N865 is a 1/2 HP three-phase motor built for continuous-duty industrial and commercial applications. Its 56 frame and rigid base suit standard mounting patterns, while dual-voltage 208-230/460V AC input covers common supply options. The totally enclosed fan-cooled design protects internal components in dirty or damp environments.
Straightforward rigid-base mounting
Installation uses the standard 56-frame bolt pattern on a rigid base, so alignment follows familiar procedures. No thermal protection is fitted, so external overload devices must be provided by the installer. Shaft rotation is reversible between clockwise and counter-clockwise to match driven-equipment requirements.
Half-horsepower output with 1.25 service factor
At 745 rpm nameplate speed the motor delivers 1/2 HP with a 1.25 service factor, giving headroom for occasional overloads. Full-load current draws 1.8-1.7 A at 208-230V or 0.90 A at 460V. Class F insulation and 40 °C maximum ambient temperature define the thermal limits for continuous operation.

Questions about this item
How do I confirm the 2N865 motor is running correctly after wiring it to 208-230/460V AC?
Verify the shaft spins freely in either CW or CCW direction, measure full-load current near 1.8-1.7 A on low voltage or 0.90 A on 460 V, and check nameplate speed is around 1,745 rpm under load.
What ships with the 2N865 and what must I source separately for installation?
The motor itself with rigid base and steel frame is included; you must supply three-phase power wiring, overload protection, mounting hardware, and any driven-equipment coupling.
Which voltage connection should I use on the 208-230/460V dual-voltage 2N865?
Configure the nine-lead winding for 208-230 V if your supply is in that range, or for 460 V if the supply is 460 V; both deliver 1/2 HP at 1.25 service factor.
