Dayton 31LH56 Three-Phase Motor 1/3 HP 56C 230/460V AC

SKU CH-DSQ1-Q36AA

Three-phase general purpose motor delivers 1/3 HP at 3510 RPM in a 56C frame with dual-voltage 230/460V AC operation

  • 1/3 HP three-phase power for industrial drives
  • 230/460 V dual-voltage wiring fits common supplies
  • 3510 RPM nameplate speed suits fan and pump loads
  • Open drip-proof enclosure with Class F insulation
  • 35 service factor handles continuous-duty overloads

Three-Phase General Purpose Motor

The Dayton 31LH56 is a new three-phase general purpose motor rated at 1/3 HP with a 56C frame. It operates on 230/460V AC at 60 Hz and features an open drip proof enclosure with a rigid base and C-face mounting. This motor suits industrial equipment requiring continuous duty in standard ambient conditions.

3510 RPM Nameplate Speed

The nameplate speed of 3510 RPM is the single specification that determines whether this motor matches the driven load. Full load current draws 1.1 A at 230 V or 0.60 A at 460 V. Insulation class F and a 1.35 service factor support reliable operation within the rated temperature range.

1/3 HP Continuous Duty Capacity

At 1/3 HP and 72 percent nominal efficiency the motor comfortably handles light-duty fans, pumps and conveyors running continuously at up to 40 °C ambient. The 56C frame with ball bearings and included shaft key provides direct coupling. It runs out when the load demands more torque than the 1.35 service factor allows or when a higher horsepower rating is required.

Questions about this item

What does the 1/3 HP rating mean once the motor is installed?

It delivers one-third horsepower at the nameplate speed of 3510 RPM, drawing 1.1 amps at 230 V or 0.60 amps at 460 V under full load.

How does the 230/460 V three-phase supply affect what the motor can do?

The dual-voltage design lets you wire it for either 230 V or 460 V three-phase, 60 Hz power; the lower voltage draws 1.1 A and the higher 0.60 A at full load.

What does the 56C frame require for mounting and shaft connection?

It uses a rigid base with a C-face flange, includes a shaft key, and fits standard 56C mounting patterns with steel frame construction.
