Can anyone out there direct me to a site that details standard NEMA sizes/dimensions for steppers? I just bought 3 Sanyo-Denki Step-Syn Nema 23 motors on ebay but haven't gotten them yet. I looked all over NEMA's site but couldn't find dimensional information (I'm assuming the numbers refer to dimensions, or do they?!?). I'm dying to start a CAD drawing of my first attempt at a CNC router. Needless to say, I've got a long way to go.
