Zusammenfassung:The present invention relates to a liner actuator driven by an electricity-driven motor. One embodiment discloses the electricity-driven linear actuator comprising: a screw operationally connected with a driving shaft of the electricity-driven motor; a nut block mounted on the screw; and a drum-shaped rod having a hollow structure for containing at least a part of the screw. One end of the rod is coupled with the nut block, so that the rod and the nut block are configured to move in an axial direction of the screw as the screw rotates. The linear actuator can generate high driving force required in a large industrial machine while significantly reducing a weight thereof. 본 발명은 전기구동 모터에 의해 구동되는 리니어 액추에이터에 관한 것으로, 일 실시예에서, 전기구동 모터의 구동축에 동작적으로 연결된 스크류; 상기 스크류에 장착되는 너트블록; 및 상기 스크류의 적어도 일부분을 수용할 수 있는 중공 구조를 갖는 통형상의 로드;를 포함하고, 상기 로드의 일단부가 상기 너트블록과 결합되어, 상기 스크류가 회전함에 따라 상기 로드와 상기 너트블록이 상기 스크류의 축방향으로 움직이도록 구성된 전기구동 리니어 액추에이터를 개시한다.
