Dayton 31LH54 Three-Phase Motor 1/4 HP 56C 230/460V
Three-phase general-purpose motor delivers 1/4 HP at 1720 RPM with dual-voltage 230/460V operation and 69.5% nominal efficiency
- 1/4 HP output powers light-duty machinery
- Dual 230/460 V AC voltage suits flexible wiring
- 1720 RPM nameplate speed matches standard 60 Hz operation
- 56C frame with C-face mounting enables direct coupling
- 5 % nominal efficiency reduces energy waste
Application Fit
The Dayton 31LH54 is a three-phase general-purpose motor rated at 1/4 HP with a 56C frame and dual-voltage 230/460V AC operation. It suits industrial equipment, HVAC drives and machinery requiring continuous duty at 1720 RPM. Buyers needing single-phase power, higher horsepower or a different frame size should look elsewhere.
Installation Notes
The motor uses a rigid base with C-face mounting and standard 56C dimensions, so alignment follows common industrial practice. No thermal protection is built in, so external overload devices must be provided by the installer. Verify rotation direction before final coupling; the shaft runs CW/CCW.
Capacity and Headroom
At full load the motor draws 1.0 A at 230 V or 0.50 A at 460 V with a 1.35 service factor giving modest overload margin. Nominal efficiency is 69.5 percent at 60 Hz. Continuous duty is rated up to 40 °C ambient; beyond that temperature rise will limit output.

Questions about this item
How do I confirm the motor reaches its 1720 RPM nameplate speed after wiring?
Measure shaft speed with a tachometer under load; it should read near 1720 RPM at 60 Hz.
What ships with the 31LH54 and what must I supply separately?
Motor only; you must provide three-phase 230/460 V supply, starter, overload protection, mounting hardware and coupling.
Which voltage connection should I use for a 230 V three-phase panel?
Wire the nine leads for the low-voltage 230 V configuration per the nameplate diagram; the motor draws 1.0 A at full load.
