I need to buy stepper motors for a hobby CNC machine I’m planning on making. Most of the motors I’m seeing are have a rating like “NEMA 23″ for instance, but don’t list the shaft’s diameter. Is there a standard, where each NEMA rating coincides with a set shaft diameter?
Thanks.

The “23″ refers to the case size. The shaft size will vary based on power output, which can vary quite a bit within a given case size. You will have to get a spec. sheet from the specific motor mfr.
