    Stepper motor linear actuator is a driving unit which converts electric pulsing signal into microstep linear motion. It adopts a stepper motor as a rotating power source and transforms rotating motion into linear motion through screw type motion. It is a device that can  replace a rotating stepper motor directly, and finally get linear motion through a set of intermediate conversion mechanism.
    Stepper motor linear actuator has simple structure and needs no intermediate conversion device. The movable part is light in weight, small in inertia and no accumulative positioning error. It is an ideal linear driving device with high positioning accuracy. The hybrid linear stepper motor is developing rapidly and has been widely applied in many fields, such as numerical control machine, autoplotter, computer device, robot, precision meter, transmission apparatus, automatic door opening and detection control.

    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.
