i have a stepper motor of step angle 1.8 degree which i have micro-stepped so that its angular movement is 0.01degree per pulse.how can i convert this into a linear motion?the linear movement is supposed
to be in the order of micro meter.(i thought of rack pinion arrangement
but then how to do it was confusing).so help me as soon as possible friends.
attach your stepper motor to a micrometer head
Think of a screw thread rod with a pitch of say 1 mm.
360 deg = 1000 micrometer advance of a nut. 1.8 degree = 5 micrometer advance. Get it?Brian Whatcott Altus OK
As usual Brian has come up with the definitive practical solution.

thanks micheal.but then i would really appreciate if you could elucidate your idea.hoping for a speedy response
I used a standard 1 inch (12tpi) bolt that I used for adjusting a roller. And like Brian states I had the following: one revolution of the screw = 1"/12tpi = 0.083" linear travel (for my needs) 1.8 degree = 0.083" / (360 / 1.8) = 0.000128 inch linear travel
