3/4 hp Capacitor-Start/Run Motor
The Dayton 119156.00 is a single-phase general-purpose motor rated at 3/4 hp with a nameplate speed of 1,725 RPM. It operates on 115/208-230V AC at 60 Hz and fits a standard 56 frame with a rigid base. The capacitor-start/run design provides reliable starting torque for continuous-duty industrial applications.
Suitable for Fixed-Speed Industrial Loads
This motor suits equipment requiring a single speed and continuous operation at a 1.25 service factor. It is usable at 208V and mounts in any angle with clockwise or counter-clockwise rotation. Buyers needing variable speed control, integrated thermal overload protection, or a totally enclosed enclosure for wet environments should consider other designs.
6.6 Amps at 115V with 1.25 Service Factor
At 115V the motor draws 6.6 full-load amps, dropping to 3.5–3.3A on 208-230V. The 1.25 service factor allows temporary overload headroom for demanding starts. Insulation class B limits the maximum ambient temperature to 40°C, so sustained high-temperature or high-altitude operation will reduce available output.

Questions about this item
What voltage supply and circuit capacity do I need to run the 115/208-230 V motor drawing 6.6 / 3.5-3.3 A?
Wire the motor for either 115 V or 208-230 V single-phase, 60 Hz. At 115 V it pulls 6.6 A full-load; at 208-230 V it pulls 3.5-3.3 A. Provide a branch circuit and protection sized to the chosen voltage per local code.
Can I keep my existing NEMA 56-frame mounting and shaft coupling when swapping to this motor?
Yes. The motor uses a standard NEMA 56 frame with a rigid base and 5/8 in keyed shaft. Bolt pattern, shaft height and keyway match other 56-frame units, so your current mounts and couplings will align.
How do I confirm the motor is delivering its rated 3/4 hp at 1,725 RPM after installation?
Measure line current at the supply voltage; it should sit near 6.6 A at 115 V or 3.5-3.3 A at 208-230 V under full load. Verify shaft speed with a tachometer — 1,725 RPM ± normal slip — and check that the casing temperature stays within the 40 °C ambient design limit.
