General-purpose capacitor-start motor

The Dayton 1K079 is a single-phase motor rated at 1/2 hp with a 56C frame and C-face mounting. It runs at 1,725 rpm on 115 V or 208-230 V AC at 60 Hz. Continuous-duty design suits conveyors, pumps and similar industrial equipment.

Thermals, noise and power draw

Totally enclosed fan-cooled construction keeps windings within a 40 °C maximum ambient temperature. Insulation class B and a 1.15 service factor provide margin for sustained full-load operation at 7.7 A on low voltage or 3.9 A on high voltage. No internal thermal protection is fitted.

Build integration

Rigid base plus C-face flange allows direct coupling to gearboxes or driven shafts without additional brackets. The keyed output shaft simplifies alignment with pulleys or couplings. Reversible CW/CCW rotation adapts to either installation orientation. Usable at 208 V for three-phase-derived supply flexibility.

Questions about this item

How do I wire the 115/208-230V AC capacitor-start motor for 230 V and what step is often missed?

Connect the dual-voltage leads for 230 V operation, install the supplied capacitor in the start circuit, and verify rotation is CW/CCW as needed; the step often missed is re-checking the capacitor wiring after the first run.

What maintenance will the 56C frame motor need during continuous duty at 40 °C ambient?

The totally enclosed fan-cooled design has no user-serviceable bearings or thermal protection, so maintenance is limited to keeping the fan cowl clear of debris and inspecting the keyed shaft for wear during scheduled downtime.

At what load does the 1.15 service factor limit appear first during sustained 1 725 RPM operation?

Continuous operation above 1/2 hp nameplate rating engages the 1.15 service factor; exceeding that overload margin causes winding temperature to reach the Class B insulation limit before any other component fails.
