actuator
An actuator is a mechanical component responsible for moving and controlling a mechanism or system. It acts as the 'muscle' of a machine by converting energy, such as electricity or air pressure, into physical motion.
例文
3 / 5The smart lock uses a small actuator to turn the bolt when you use the smartphone app.
The digital lock contains a tiny mechanical mover to shift the locking pin via the phone application.
Each hydraulic actuator must undergo a rigorous safety inspection before being installed in the aircraft.
Every fluid-powered moving part needs a strict safety check before placement in the airplane.
I think the actuator in my car's window is broken because it won't slide up anymore.
I believe the motor part for my car window is failing because the glass is stuck down.

よく混同される語
An activator starts a process (like a chemical or social one), while an actuator is specifically a mechanical device that creates physical motion.
A sensor detects information from the environment, whereas an actuator performs an action based on that information.
使い方のコツ
The term is primarily used in technical fields like engineering, robotics, and manufacturing. It refers to the specific part that makes things move rather than the entire machine.
よくある間違い
Learners often use 'motor' for everything, but 'actuator' is the correct term for components that create linear motion or operate valves in industrial contexts.
覚え方のコツ

語源
Derived from the Latin 'actus' (a doing or driving) and 'actuate' (to put into motion).
文法パターン
文化的な背景
The term is increasingly relevant in modern culture due to the rise of 'Industry 4.0' and smart home automation where actuators control everything from smart blinds to robotic vacuums.
