Three-Phase General Purpose Motor
The Dayton 31LH48 is a 1 HP three-phase AC motor built for continuous duty in industrial and commercial equipment. Its 56C frame and C-face mounting suit direct-coupled pumps, fans, and gearboxes where a compact footprint is required.
Dual-Voltage 230/460 V Operation
Nameplate data lists full-load current at 3.0 A on 230 V and 1.5 A on 460 V, so the installer must match the supply voltage and starter settings to the correct winding connection.
Sustained Load Performance
Rated for continuous duty at 40 °C ambient, the motor delivers 77 % nominal efficiency at 3470 RPM with a 1.25 service factor, and its Class F insulation and ball bearings support steady operation without thermal protection.

Questions about this item
What does the 3470 nameplate RPM mean when the motor is installed?
It indicates the shaft will spin at roughly 3470 revolutions per minute under full load on a 60 Hz supply.
How does the 230/460V three-phase rating limit the motor in practice?
It requires a three-phase 230 V or 460 V supply; single-phase power cannot run it without a converter.
What does the 56C frame with C-face mounting need to bolt up?
A 56C C-face flange with the standard bolt circle and a shaft key for the driven equipment.
