Product Identity
The Dayton 119157.00 is a single-phase general purpose motor rated at 3/4 hp with a capacitor-start/run design. It delivers 1,725 RPM nameplate speed on a 56 frame and suits continuous-duty industrial or commercial equipment.
Installation Checks
Verify that your supply voltage matches the dual rating of 115/208-230V AC at 60 Hz and that the starter circuit can handle 6.6 A at 115V or 3.5-3.3 A at the higher voltages. Confirm the driven load does not exceed the 1.25 service factor and that the mounting surface accepts a rigid base in any orientation.
Build & Connections
The open drip-proof enclosure with closed base and Class B insulation is rated for 40 °C maximum ambient temperature. Automatic thermal protection resets after a fault, while the CW/CCW reversible shaft and all-angle mounting give flexibility for belt, direct-couple or gear-driven layouts.

Questions about this item
What comes in the box with the Dayton 119157.00 motor and what must I purchase separately?
The motor ships as a single unit with a rigid base and 56 frame. Capacitors, wiring, pulleys, couplings and mounting hardware are not included and must be sourced separately.
How do I decide between the 115 V and 208-230 V connections on this motor?
The motor is dual-voltage: wire it for 115 V and expect 6.6 A full-load current, or wire it for 208-230 V and expect 3.5-3.3 A. Choose the voltage that matches your supply and circuit capacity.
What does the 1725 RPM nameplate speed mean once the motor is loaded in my application?
The nameplate rating is 1725 RPM at full load with a 1.25 service factor. Under continuous duty at 40 °C ambient the motor will run at or near that speed; lighter loads will run slightly faster.
