I have never used steppers so far in any application, but I know the Kollmorgen sizing software referenced to in the link includes steppers in the selection process, I know that both servo's and steppers in the software is geared to the Kollmorgen line, I usually just use it as a guide line when selecting a motor for a particular application to get a rough motor load inertia match.
Over time I have come across alot of info off the manufacturers sites, and downloaded considerable information, which I found was a fortunate habit as many sites have changed and no longer appear to offer the same info anymore.
e.g. Sanyo Denki had an excellent Handbook of Servo Systems on their site which no longer exists.
The moral is, if you see it, save it.
