DAYTON 3-Phase NEMA Frame General Purpose AC Motor

NEMA 180 frame three-phase general purpose AC motors have a standard 1-1/8" diameter, 2-3/4" length shaft whose center is 4-1/2" above the mounting surface. Variations to the frame's standard dimensions and design are indicated by a letter designation following the frame number, such as 182TC. The letter "T" specifies integral HP motor dimension standards set by NEMA in 1953 and 1964, "C" indicates that the motor can be face mounted. The combined suffix "CH" indicates that the face-mounting dimensions differ from frames with a "C" letter designation. These frame standards and letter designations are defined by the National Electrical Manufacturers Association (NEMA).
