This is high quality Nema 11 stepper motor linear actuator with 1.8 deg. step angle (200 steps/rev). Each phase draws current 0.67A at 3.8V voltage, allowing for a holding torque of 8.3 Oz-in. You can choose a external shaft type or a non-captive shaft type stepper linear actuator to meet your specific application requirements.Stepper Motor Linear Actuator Specification

Stepper Motor Linear Actuator Dimension1. Non-captive shaft style2. External shaft styleTips: Basic principle of stepper motor linear actuatorThe stepper motor linear actuator is meshed with a screw and nut, so as to prevent the relative rotation of the screw nut so that the screw will have axial movement. There are two ways to achieve this transformation. The first is to build a rotor with inner screw thread in the stepper motor so as to achieve the linear motion through the mesh of internal thread and the screw. The second is to use the screw as the output shaft of the motor. A linear motion is achieved by meshing the external drive nut and screw. It simplifies the design greatly so that precise linear motion can be carried out in many application areas without installing external mechanical linkage device.
ATO external stepper linear actuator in this video is 2 phase 4 wire comes in Nema 23 frame size. We will show you how to use PLC connect to the hybrid stepper motor system, and control this external stepper motor linear actuator for simple forward and reverse motion by the pulse and direction command issued by PLC.
