AO Smith F391 Three Phase TEFC Induction Motor

AO Smith F391 is a 3 horsepower, three-phase induction motor with a 182T frame and a TEFC (totally enclosed fan-cooled) enclosure, configured for dual-voltage operation at 230 and 460 VAC. It runs at 1760 RPM, a four-pole speed typical for standard line frequencies and well suited to a broad range of mechanical loads. TEFC construction protects the windings from dust, moisture, and other contaminants while the integrated fan provides cooling for continuous-duty or intermittent-use applications. As a general-purpose, NEMA-frame motor, the F391 is commonly applied to pumps, fans, conveyors, and machine tools in manufacturing and process environments, offering rugged, reliable performance with straightforward replacement and cross-reference in catalogs. With 230/460 V compatibility and a standard 182T frame, it fits a wide array of existing equipment and replacement components, making it a practical choice for upgrades where a 3-phase TEFC motor is required.
