A A captive linear stepper motor is a type of linear stepper motor that converts electrical pulse signals into precise linear motion. It features an integrated nut captured inside the motor housing, which prevents the nut from rotating while allowing it to move linearly along the lead screw. This design ensures stable, smooth, and accurate linear positioning.

A A captive linear stepper motor offers several advantages including high positioning accuracy, minimal backlash, smooth linear motion, strong axial load capacity, and easy integration into automation systems. These characteristics make it suitable for precision equipment and industrial motion control applications.

A Many engineers choose captive linear stepper motors for CNC machines, robotics systems, and automation equipment because the captive design provides repeatable linear movement with reduced backlash and consistent performance, which is essential for high-precision positioning tasks.

A Besfoc manufactures captive linear stepper motors in multiple standard NEMA sizes, including NEMA 8, NEMA 11, NEMA 17, and NEMA 23. Each frame size can be configured with different motor body lengths, screw leads, and travel strokes to suit various linear motion applications.

A In a captive linear stepper motor, the nut is securely held inside the motor housing, preventing it from rotating freely. This structure eliminates mechanical slack and reduces backlash, resulting in more accurate positioning and improved repeatability during motion control operations.
