external step motor actuator

A common way to generate precise linear motion is to use an electric motor (rotary motion) and pair it with a lead screw to generate a linear actuation system.  Depending upon what this linear actuator interfaces with it can be constructed in a number of different ways.  Here we will discuss several different ways to combine a lead screw and nut with a stepper motor to create a linear actuator system…
