actuator

Thân thiện

A robotic arm uses an actuator to pick up a small component.

Definition

Noun: A device or mechanism that causes a machine or system to operate or move. It converts energy (often electrical, hydraulic, or pneumatic) into physical motion or action, putting something into automatic or controlled operation.

Usage

An actuator is a core component in automated systems. It receives a control signal and energy source, then produces the corresponding mechanical motion to control a mechanism. - The actuator is responsible for moving the robotic arm. - A linear actuator extends and retracts in a straight line. - The valve is opened by an electric actuator.

Examples

Advanced Usage

• "Actuator fault": A failure in the actuating mechanism, often used in engineering diagnostics.
  • The system shutdown was caused by an actuator fault in the cooling unit.
• "Actuator saturation": A state where an actuator has reached its physical limit of motion or force output.
  • The controller must account for potential actuator saturation to avoid system instability.

Variants and Related Words

• Actuate (verb): To cause a machine or device to operate.
  • This button actuates the emergency release mechanism.
• Actuation (noun): The process of putting something into action or motion.
  • The actuation of the lock is nearly instantaneous.

Synonyms

• Mover: A device that imparts motion.
• Driver: A component that drives or controls another part of a mechanism.

Related Phrases

• "Actuator arm": The moving part of an actuator, often found in devices like hard disk drives.
  • The read/write head is positioned by a precise actuator arm.
• "Actuator shaft": The rotating or linear output component of an actuator.
  • Seal the actuator shaft to prevent dust ingress.
