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).
