Neither seem to be steppers, just maybe DC motors .. ???
AFAIK the minimum number of wires to a stepper is 4, ie bipolar connected.
'escap' ??
Portescap ??
http://www.portescap.com/category-brush-dc.htmlTheir stuff is very good and very expensive IIRC .. not your usual junk.
Cannot find anything in the search box with the numbers you gave.
Both motors should turn by hand, unless there is a reduction gearbox attached to them, in which case you may have problems in the gearbox, or more likely, a high reduction ratio. If, in fact, you are turning a g/box output shaft, you may be trying to spin the motor itself at a high rate of knots.
They don't by any chance vaguely resemble this motor ?? ie an ally blob on the end ??
