I did a "define:" on Google, and it told me that NEMA means "The National Electrical Manufacturers Association". However, I see "Nema 17", "Nema 23", etc steppers listed on websites. Is "NEMA" a generic term, or the name of a manufacturer, or what? What does it mean?
Secondly, how fast can I expect a NEMA 17 to reliable move a moderate load? e.g. - A 1/4" router bit plunging into solid wood.
