- UL, CSA and CE certifications confirm safety compliance
Industrial three-phase motor
The Dayton 4GYY8 is a 2 HP general-purpose motor built for continuous duty in industrial environments. Its totally enclosed fan-cooled design protects internal components while delivering 1165 RPM nameplate speed. Dual-voltage 208-230/460V AC operation suits standard North American three-phase supplies.
Replaces worn direct-drive units
This frame 182/4T motor fits existing rigid-base mounts without modification, making it a drop-in replacement for failed units of the same frame and power rating. The 1.15 service factor provides margin for intermittent overloads, and 88.5 percent nominal efficiency reduces operating cost over older standard-efficiency models. Upgrade is justified when the original motor shows bearing noise, insulation breakdown or repeated thermal trips.
Suits pump, fan and conveyor drives
The steel frame and ball bearings handle continuous 40 °C ambient conditions in material-handling and HVAC equipment. CW/CCW rotation flexibility simplifies installation on reversible loads. Buyers needing single-phase power, integrated thermal protection or a different frame size should select an alternative model.

Questions about this item
Will the 182/4T frame fit my existing mounting base?
The rigid base matches NEMA 182/4T dimensions, so it bolts directly to any standard 182/4T mounting pattern without adapters.
Which wiring step is most often missed on the 208-230/460V dual-voltage terminal block?
Installers frequently forget to reconfigure the nine leads for the chosen voltage; follow the diagram on the nameplate to set 230 V or 460 V before powering up.
When should the sealed ball bearings be inspected or replaced?
Bearings are sealed for life; plan a vibration and temperature check at each scheduled shutdown — typically annually — and replace only if noise or heat exceeds normal limits.
