Dayton 5K480 Capacitor-Start Motor 1 hp 115/230V AC 182 Frame 1750 RPM

Dayton 5K480 Capacitor-Start Motor

The Dayton 5K480 is a general-purpose, single-phase motor rated at 1 hp with a nameplate speed of 1750 RPM. It operates on dual-voltage 115/230V AC at 60 Hz and fits a NEMA 182 frame. The capacitor-start design provides strong starting torque for belt-driven or direct-coupled loads. Its open drip-proof enclosure and Class F insulation suit clean, dry indoor environments.

Suited for continuous-duty industrial equipment

This motor suits continuous-duty applications such as pumps, fans, compressors and conveyors that need a rigid horizontal base mount and a keyed shaft for positive drive engagement. The 1.25 service factor gives a modest overload margin. Buyers who need built-in thermal protection, a vertical mounting option or an enclosed housing for dirty or wet locations should look at alternative designs.

1 hp output with 1.25 service factor

At 115V the motor draws 14.4 full-load amps; at 230V it draws 7.2 amps, so circuit sizing must match the chosen voltage. The 1.25 service factor allows temporary operation up to 1.25 hp without overheating in a maximum ambient temperature of 40 degrees C. It is not designed for variable-speed control or frequent start-stop cycling beyond normal continuous duty.
