56 frame motor shaft size.

56j face 5has 3a threaded shaft of stainless steel while all others have a keyed steel shaft. These exceptions are noted in the general catalog. Drawings represent standard tefc general purpose motors refer data section 502 for various models open or tefc d im e ns oa rf c ly. For a two digit frame divide the frame number by 16 to arrive at this dimension.

The frame number relates to the d dimension distance from center of shaft to center bottom of mount. Typical examples of frame numbers 48 56 145 and 215. For c flange motors refer to diagram 2. For the d dimension of a three digit frame number consider only the first two digits and use the divisor 4.

The frame number relates to the d dimension distance from center of shaft to center bottom of mount. Dimension v is shaft length available for coupling pinion or pulley hub this is a minimum value. Electrical motor shaft power electrical motors are rated in horsepower or watt.

The largest of the current fractional horsepower frame sizes is a 56 frame which is available in horsepowers greater than those normally associated with fractionals. For example in the two digit 56 frame the d dimension is 31 2. Iec nema standard torques iec and nema torque classifications of electrical motors. 56 divided by 16 31 2.

The frame number relates to the d dimension distance from center of shaft to center bottom of mount. Base of 56hz frame motors has holes and slots to match nema 56 56h 143t and 145t mounting dimensions. Similarly a 56 frame motor would have a shaft height of 3 1 2 inches. In any standard frame number designation there are either two or three numbers.

For example in the two digit 56 frame the d dimension is 3 56 divided by 16 3. For example in the two digit 56 frame the d dimension is 3 56 divided by 16 3. Certain nema 56z frame motors have 1 2 x 1 1 2 long shaft with 3 64 flat. And apply to all base mounted motors listed herein that carry a nema frame 1designation.
