General-Purpose Motor for Continuous Duty
The Dayton 30PT79 is a single-phase capacitor-start/run motor rated at 1 hp with a 56 frame. It operates on 115/230V AC at 60 Hz and delivers a nameplate speed of 1,140 RPM. The open drip-proof enclosure and Class B insulation support continuous operation in ambient temperatures up to 40 degrees C.
Suited for Fixed-Speed Industrial Equipment
This motor suits conveyors, pumps, fans and similar machinery that run at a constant speed and require reversible rotation. Its cradle-base mounting and horizontal orientation limit use to applications that can accommodate that footprint. Buyers needing variable-speed control should look elsewhere because the unit is not inverter rated. Single-phase sites without 115/230V supply cannot use it.
Auto Thermal Protection and Dual-Voltage Wiring
Automatic thermal protection resets itself after an overload, reducing unplanned downtime on unattended equipment. The dual-voltage design lets the installer wire for either 115V at 8.9 A or 230V at 4.6 A without buying separate motors. A 1.15 service factor provides a modest margin for occasional peak loads beyond the 1 hp rating.

Questions about this item
What voltage supply do I need to run the 1 hp motor?
The motor operates on 115/230V AC single-phase power at 60 Hz.
Will the 56 frame fit my existing cradle base mounting?
Yes, it uses a 56 frame with cradle base mounting designed for horizontal installation.
How can I verify the motor is running at the correct speed after installation?
Check that the shaft rotates at 1,140 RPM under full load; the motor is single-speed and not inverter rated.
