Like most linear motors, a linear stepper motor is essentially a variation of the rotary design, cut radially and laid out flat. Similar to their rotary counterparts in operation and performance, a linear stepper motor is typically run as open-loop systems and are capable of providing high resolution at high speeds and accelerations.
The linear stepper motor almost exclusively employs a hybrid design, with two main parts—a base (also referred to as a platen) and a slider (also referred to as a forcer). Unlike other linear motor designs, in a linear stepper motor, the platen is a passive component—a steel (or stainless steel) plate with slots milled into it. The forcer contains laminations with slotted teeth, motor windings, and a permanent magnet. The teeth of the forcer concentrate the magnetic flux that is created when current is applied to the coils. The forcer teeth are also staggered in relation to the platen teeth—typically by ¼ tooth pitch—to ensure that constant attraction is maintained and that the next set of teeth will come into alignment as current is switched in the coils. For each full step of the motor, the forcer moves ¼ tooth pitch.

There are two types of nuts,copper nut and POM nut
Computer controlled stepper motors are a type of motion-control positioning system. They are typically digitally controlled as part of an open loop system for use in holding or positioning applications.
In the field of lasers and optics they are frequently used in precision positioning equipment such as linear actuators, linear stages, rotation stages, goniometers, and mirror mounts. Other uses are in packaging machinery, and positioning of valve pilot stages for fluid control systems.
Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, image scanners, compact disc drives, intelligent lighting, camera lenses, CNC machines and, more recently, in 3D printers.
