NEMA 140 frame three-phase general purpose AC motors have a standard 7/8″ diameter, 2-1/4″ length shaft whose center is 3-1/2″ above the base mounting surface. Variations to the frame’s standard dimensions and design are indicated by a letter designation following the frame number, such as 143T or 145TC. The letter ?T? specifies integral HP motor dimension standards set by NEMA in 1953 and 1964, and ?C? indicates that the motor can be face mounted. These frame standards and letter designations are defined by the National Electrical Manufacturers Association (NEMA).

NEMA 56 frame three-phase general purpose AC motors have a standard 5/8″ diameter, 1-7/8″ length shaft whose center is 3-1/2″ above the base mounting surface. Variations to the frame’s standard dimensions and design are indicated by a letter designation following the frame number, such as 56HZ or 56C. The letter ?H? indicates that the frame has a set of mounting holes at 3″ and 5″, ?Z? indicates that the frame has a nonstandard shaft, and ?C? indicates that the motor can be face mounted. These frame standards and letter designations are defined by the National Electrical Manufacturers Association (NEMA).
