1.8° 1.33A 2.8v 2.6kg.cm Nema17 stepper motor with screw lead
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.
