Motor Specifications

The Dayton 31TT03 is a single-phase, capacitor-start/run general-purpose motor rated at 1 HP with a nameplate speed of 3,450 RPM. It uses a 56 frame with a rigid base for horizontal mounting and a keyed shaft that rotates in either direction.

Suitable Applications

This motor suits equipment requiring continuous-duty operation at 60 Hz on 115 V or 208–230 V supplies, drawing 8.8 A at the lower voltage and 4.9–4.4 A at the higher. Buyers needing inverter-rated operation, thermal overload protection, or a different frame size should look elsewhere.

Installation Checks

Verify that your supply voltage matches 115 V or 208–230 V AC and that the mounting surface accepts a 56-frame rigid base in a horizontal position. Confirm the driven load can accommodate a keyed shaft with reversible rotation and that ambient temperature will not exceed 40 °C.
