1/2 hp Capacitor-Start/Run Motor
The Dayton 119191.00 is a single-phase general purpose motor rated at 1/2 horsepower. It operates on 115/208-230V AC at 60 Hz with a nameplate speed of 1,140 RPM. The motor features a 56 frame rigid base mounting suitable for all-angle installation. Its open drip-proof enclosure and Class B insulation support continuous duty cycles in ambient temperatures up to 40 degrees C.
Upgrade From Split-Phase Or Smaller HP Motors
This capacitor-start/run design provides higher starting torque and better running efficiency than basic split-phase motors of similar size. The 1.25 service factor allows sustained operation above nameplate load without overheating. The jump is worth it when replacing failed motors on compressors, pumps, or conveyors that need reliable starting under load and dual-voltage wiring flexibility.
Suits Industrial Maintenance And OEM Replacement
Maintenance teams standardising on 56 frame footprints will find the rigid base and CW/CCW rotation simplify swaps. The lack of built-in thermal protection means external overload devices are required for code compliance. Buyers needing totally enclosed enclosures, automatic thermal overloads, or three-phase power compatibility should look at alternative motor designs.

Questions about this item
What shaft height does the 56-frame motor require for mounting?
The 56-frame rigid-base motor uses standard NEMA 56 dimensions, so the shaft centreline sits 3.5 inches above the base; verify your mounting plate matches that height before bolting it down.
Which voltage jumper setting should I select for a 208 V supply?
The nameplate lists 115/208-230 V; move the internal jumpers to the 208-230 position and connect the leads for 208 V operation — using the 115 V setting on 208 V will damage the windings.
How often should I inspect the open drip-proof enclosure for debris?
Because the enclosure is open drip-proof, schedule a visual check every three to six months; blow out dust and lint from the vent openings to keep the 40 °C ambient rating valid and prevent insulation breakdown.
