Hello,

ive seen some almost number alike steppers in ibm proprinters
Sanyo denki step-syn
103G770-2521              DC4,1v 1,1A 1,8 deg/step
103G770-2511              DC4,1v 1,1A 1,8 deg/step

i liked them
because i think they are nice to use for plotter alike tables
i want to make

i have already made a plotter with steppers found in epson printers
but they are much smaller with less amperes and less torq i think
http://home.wxs.nl/~luberth/plotter/plotter.htm

the step syn i have is aprox 2.25 inch in diameter and 2 inch in length
and a shaft of 0.25 inch

i have been searching for more ibm proprinters but no luck

i have no idea what such moters should cost

if the price is not so high i would be interested in a few
but i don't now if it is word shipping because of the weight
my location is holland

warning dont open stepper moters if you are curious what the inside
looks like
it wil destroy the moter
it will loose a lot of magnetic current
and wil therefore loose torq when put togheter again

for more info of how to use steppers
visit my plotter page and use the link to ian harries
lots of info and links there

greeting's from holland
