Re: newbie needs help with stepper motor
I don't know of anything like that offhand. You will probably need some more detail regarding dimensions, mounting hole locations # shaft size. Some useful search terms that might get you closer are:
"unipolar 48-step motor"
That yields plenty of hits - mostly on ebay. Unfortunately, most do not have detailed specifications.

How close to the specs to things need to be?
By the way, I think the part number is PM4222-09.
