Farm duty motor for continuous use
The Leeson 113938.00 is a single-phase 1-1/2 HP farm duty motor built for continuous operation. Its capacitor-start/run design delivers reliable torque for blowers, fans and similar equipment in agricultural or industrial settings. The totally enclosed fan-cooled enclosure protects internal components from dust and moisture.
Dual-voltage flexibility with thermal margin
Rated for 115 V or 208-230 V AC at 60 Hz, the motor draws 17.2 A at low voltage and 8.8-8.6 A at high voltage. A 1.15 service factor provides headroom for occasional overload, while Class F insulation and a 40 °C maximum ambient temperature support sustained duty. Manual thermal protection requires operator reset after a trip.
56HZ frame limits mounting options
The rigid-base 56HZ frame fixes the mounting footprint and shaft height, so the unit suits horizontal installations on a flat surface only. Rotation is field-reversible between CW and CCW. Operation at 200 V is not supported, and the single-speed 1 725 RPM output cannot be varied without external controls.

Questions about this item
Will the 56HZ frame and 115/208-230V wiring match the mounting holes and voltage of my existing 1-1/2 HP farm motor?
The 56HZ frame and dual-voltage 115/208-230V design match common farm-duty footprints; verify your old motor’s frame code and supply voltage before swapping.
How can I confirm the blower is running at the nameplate 1,725 RPM after installation?
Measure shaft speed with a tachometer; it should read 1,725 RPM at 60 Hz under full load with the 1.15 service factor applied.
Does the box include a capacitor, mounting bolts or a power cord, or must I source them separately?
The motor ships as a bare rigid-base unit; capacitor, mounting hardware and supply cord are not included and must be purchased separately.
