General-purpose three-phase motor
The Dayton 31TU36 is a 2 HP three-phase motor built for continuous industrial duty. Its 143-5TC/56HCZ frame fits standard C-face mounting, making it a direct replacement for pumps, fans and conveyors that demand reliable torque at 3505 RPM.
Steel frame with rigid base and ball bearings
A totally enclosed fan-cooled enclosure protects windings from dust and moisture while the steel frame and rigid base resist vibration. Dual-voltage 230/460 V windings draw 4.9 A at low voltage and 2.5 A at high voltage, and Class F insulation supports a 40 °C ambient rating for long service life.
Upgrade from single-speed or lower-efficiency units
The 86.5 % nominal efficiency and 1.25 service factor reduce energy cost and handle intermittent overloads better than standard-efficiency models. Buyers who need variable-speed control or a different frame size should look elsewhere, as this motor is fixed-speed and frame-specific.

Questions about this item
What voltage does the 230/460V AC three-phase supply require for full-load operation?
The motor runs on 230 V or 460 V AC three-phase at 60 Hz, drawing 4.9 A at 230 V and 2.5 A at 460 V under full load.
Which frame and mounting combination does the 143-5TC/56HCZ frame with C-face and rigid base need?
It fits a 143-5TC or 56HCZ frame footprint, uses a C-face flange for direct coupling, and bolts to a flat surface through the rigid base.
How do you wire the dual-voltage 230/460V leads for the correct rotation?
Connect the nine leads for 230 V or 460 V per the nameplate diagram, then swap any two line leads to reverse CW/CCW rotation.
