Motor Design & Output
The Dayton 30PT43 is a single-phase general-purpose motor rated at 1/3 horsepower with a nameplate speed of 1725 RPM. It uses a capacitor-start/run design for reliable torque and operates on dual-voltage 115/230V AC power at 60 Hz.
Frame & Mounting
The 56C frame incorporates a C-face with rigid base for secure horizontal mounting. A 1.35 service factor provides a margin above the nameplate load, while Class B insulation supports continuous duty in ambient temperatures up to 40 °C.
Electrical Limits & Protection
Full-load current draws 3.8 amps at 115V or 1.9 amps at 230V, and the open drip-proof enclosure allows airflow without built-in thermal protection. The motor is not inverter rated, so it suits fixed-speed applications only. Buyers needing variable-frequency drive compatibility or integrated overload protection must look elsewhere.

Questions about this item
What frame size and mounting style does the 56C motor require?
The motor uses a NEMA 56C frame with a C-face and rigid base for horizontal mounting.
Which voltage leads do I connect for 115 V or 230 V operation?
Wire the dual-voltage terminals for either 115 V at 3.8 A or 230 V at 1.9 A as shown on the nameplate diagram.
How often should I inspect the open drip-proof enclosure for debris?
Check the open vents every few months and clean dust buildup to keep airflow within the 40 °C ambient limit.
