Running torque will start out about 90 oz in and quickly drop a speed
increases. Among other reasons for this as speed increases each coil
has less time to charge,... a reason for operating steppers at 10 to
25 times their rated voltage. Higher voltage, ie : faster current
rise. But you need a driver that can chop the current at low rpms,..
otherwise they will burn up. I don't have the math in front of me ,
but running them at just their rated voltage at 2 to revs a sec could
be as little as 10 % the holding torque. Someone may know this a
little better.
