The Emerson K050S172 series is a rugged, industrial-duty, single-phase motor designed for the most demanding continuous-duty applications. Part of Emerson's prestigious K-Series line, this motor is engineered to provide reliable starting torque and consistent operation in environments where standard motors fail. It is ideally suited for applications such as compressors, pumps, conveyors, material handling equipment, machine tools, and agricultural machinery requiring a 1/2 HP, 1725 RPM power plant. The K-Series construction features heavy-gauge steel frames, cast iron end shields, and a Totally Enclosed Fan Cooled (TEFC) enclosure to withstand dust, moisture, and harsh industrial conditions.
