DAYTON 3N427B6 General Purpose Industrial Motor, 3-Phase, 3/4 HP, 208-230/460V AC, 1155 RPM, TEFC, 56H Frame

Condition: New – no usage indicated, assumed unused and compliant with CSA and UL certifications.

The DAYTON 3N427B6 is a rugged, three-phase general-purpose industrial motor built for reliable performance across a broad range of commercial and industrial applications. Featuring a 3/4 HP rating and operating at 208-230/460V AC, this motor is designed with a Totally Enclosed Fan Cooled (TEFC) enclosure to provide superior protection against dirt, dust, and moisture. Built on a 56H rolled steel frame, it offers a rigid base mount adaptable to all angle mounting positions, making it highly versatile. Its low-speed, high-torque 1155 RPM output suits applications requiring controlled movement, making it a strong choice for conveyors, fans, blowers, pumps, and material handling equipment. The inverter-rated design also ensures compatibility with Variable Frequency Drives (VFDs) for speed control.

The motor’s keyed shaft design and ball bearings enhance stability and efficiency during continuous-duty operations, while a nominal efficiency of 78.5% delivers dependable energy savings in demanding environments.
