A stepper motor linear actuator converts the rotary output of a stepper motor into precise linear movement directly within the drive itself, eliminating the external rack-and-pinion or belt-and-pulley mechanisms traditionally used to create linear motion. Because a stepper advances a fixed increment with every electrical input pulse, this integrated approach delivers the high resolution and repeatable positioning that demanding automation applications require. igus® stepper motor linear actuators pair a drylin® stepper motor with a high helix dryspin® lead screw and a matching lead screw nut, and are offered in NEMA 11, 17, and 23 frame sizes, each rated to IP40. The complete system operates without the need for external lubrication, allowing reliable, maintenance-free performance, while consistent torque and a compact, cost-effective design make these actuators well suited to industrial automation. They can also be combined with drylin® motor controllers and drylin® E motor and encoder cables to build a complete automated system from a single source.
