Linear stepper motors are offered with a variety of lead-screws, which are designated by their lead. Lead is the distance the nut travels when the lead-screw turns one revolution. For a linear stepper motor, larger leads will make the nut move faster, but with less force.
To determine the linear travel per step divide the screw lead by the motor steps / revolution. For example: Lead designation E062 has a lead of 1.588 mm (.0625”). With a 1.8 degree step motor the movement per step is 1.5875 / 200 = 0.00794 mm / step (.062 / 200 = 0.0003125 inch / step). Note: the E in the E062 designation indicates this is based on inches, and the mm values have been rounded.
