Three-Phase Motor for Industrial Equipment
The Dayton 31LH69 is a three-phase general-purpose motor rated at 2 HP with a 56HC frame. It operates on 230/460V AC at 60 Hz and delivers a nameplate speed of 3510 RPM. The open drip-proof enclosure and steel frame suit indoor industrial environments where airflow is unrestricted. Rigid base mounting and a C-face design allow direct coupling to pumps, fans or gearboxes.
Suits fixed-speed drives.
This motor runs at a constant 3510 RPM with no thermal protection, so it fits continuous-duty applications that do not require speed control. Buyers who need inverter-ready windings, built-in overload protection or an enclosure rated for wash-down or explosive atmospheres should look elsewhere. The 1.15 service factor provides a modest margin for occasional overload but does not replace a dedicated protective device.
Shaft key included for immediate coupling
A shaft key is supplied in the box, letting maintenance teams mount a coupling or pulley without sourcing a separate keyway component. Ball bearings and Class F insulation support the rated 40 °C maximum ambient temperature. No software, controllers or additional accessories are bundled with this motor.

Questions about this item
What three-phase voltage supply does the 31LH69 motor require?
The motor is rated for 230/460 V AC three-phase power at 60 Hz.
Can the 56HC frame motor be mounted on a legacy rigid base with C-face bolt pattern?
Yes, it has a rigid base and C-face mounting compatible with standard 56HC dimensions.
How can I verify the 2 HP motor is running at its nameplate speed after installation?
Measure shaft speed under load; it should read approximately 3510 RPM per the nameplate rating.
