Translation guide
A device that converts energy into motion or physical action, often used in engineering and robotics. In Japanese, the English loanword アクチュエーター is standard, but native terms like 駆動装置 are also used in technical contexts.
A component that moves or controls a mechanism, such as in robotics, automotive, or industrial systems.
The most common and direct equivalent, used across technical fields. A loanword from English, widely understood by engineers.
このロボットには複数のアクチュエーターが搭載されている。
This robot is equipped with multiple actuators.
A native Japanese term meaning 'drive device' or 'actuator'. Common in mechanical engineering contexts, especially when emphasizing the driving function.
この駆動装置は油圧で動く。
This actuator operates hydraulically.
Literally 'operation part', sometimes used for actuators in control systems or valves, but less specific than アクチュエーター.
バルブの操作部を点検してください。
Please inspect the valve actuator.
An actuator as part of a larger system like a car engine or aircraft control surface.
Still the standard term; often used with modifiers like 電動 (electric) or 油圧 (hydraulic).
電動アクチュエーターがスロットルを制御する。
An electric actuator controls the throttle.
Means 'actuating device', used in aerospace and heavy machinery. Slightly more formal than 駆動装置.
In modern engineering, アクチュエーター is overwhelmingly used. Native terms like 駆動装置 may sound slightly dated or overly formal in some contexts, but are still correct.
航空機の作動装置は高い信頼性が求められる。
Aircraft actuators require high reliability.
