I've got a whole box of surplus mystery steppers that I've been
wanting to ID, NEMA 17, 23, and a couple size 34. Most don't have
all the specs printed on them. Do you have other "rule of thumb"
numbers for wattage, for the other frame sizes?

I assume single/double/triple stack has to do with the length of
the motor. Are these lengths standardized? Is there a website
or other resource that has all of the NEMA size motor dimensions?

Thanks,
