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.
