How to find shaft diameter on stepper motors?
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.
