PURPOSE: A linear actuating device is provided to independently control a plurality of linear actuators by combining optimized servo motor controller to a linear actuator structure and to enhance responsibility and control reliability. CONSTITUTION: An actuator main body(101) forms an opening window on a part of sidewall to a length direction. A ball screw is composed of a screw unit and a shaft unit. A ball screw nut is combined with the external diameter of the screw unit by using a screw and spirally moves upward and downward. The bottom of a slide shaft is combined with the ball screw nut. A servo motor(300) provides torque to the ball screw. A main body is combined with the external diameter of the slide shaft. A slide guide is composed of a guide protrusion having a guide groove. |
