Hi! Anybody know of a place where I can get some stepper motors with a 6mm shaft (NEMA 23)? I'm looking to replace some 5-phase stepper motors for a 4th axis. Thanks!

How about 6.35?

NEMA 23 wouldn't have a 6mm shaft because NEMA 23 is an inch based standard(6.35mm=1/4 inch). NEMA does have metric standards, but they all end in multiples of 5(ie NEMA 70, NEMA 75).

I actually bought a kelinginc stepper motor to use with the 4th axis but after trying to jam it into the harmonic drive hub with no luck I soon realized I needed a stepper motor with a 6mm shaft. I actually did a search and found

but I'm hoping that someone has seen one on ebay, or some US based site.

Different models of Toshiba photocopiers provided me with nema 23 sized motors using the 6.0mm and 6.35mm sized shaft.
