actuator 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. a mechanism that puts something into automatic action
  2. An actuator is a mechanical device for moving or controlling a mechanism or system. It takes energy, usually transported by air, electric current, or liquid, and converts that into some kind of motion.
  3. (Actuators) Devices that perform the actual work commanded by the on-board computer. Actuators can be in the form of a motor, relay, switch, or solenoid.
  4. (Actuators) Hydraulic cylinder Swashplates are used in 'hydraulic motors' requiring highly accurate control and also in 'no stop' continuous (360o) precision positioning mechanisms. These are frequently driven by several hydraulic pistons acting in sequence. ...
  5. (Actuators) Mechanisms for activating process control equipment by use of pneumatic, hydraulic, or electronic signals.
  6. (actuators) ( motors)/ effectors ( claws, etc.)
  7. An electrical mechanism for moving or controlling something indirectly instead of by hand, such as a door lock. Output device the PCM controls such as solenoids, relays, fuel injectors and stepper motors.
  8. A mechanical assembly that positions the read/write head over the appropriate track.
  9. In a closed-loop control system, that part of the final control element that translates the control signal into action by the control device.
  10. A motorized assembly that allows an antenna to scan the arc of satellites under remote control.
  11. A device used to operate a damper or control valve.
  12. Mechanism that moves an object; for example, the read/write head on a disk drive.
  13. Device that performs an action or outputs a signal in response to a signal from a computer.
  14. A device that creates mechanical motion by converting various forms of energy to rotating or linear mechanical energy.
  15. An electric, hydraulic, mechanical or pneumatic device, or combinations of these, that will provide a predetermined mechanical movement.
  16. A power mechanism used to effect motion, or maintain position of the robot (for example, a motor which converts electrical energy to effect motion of the robot) (R15.07). The actuator responds to a signal received from the control system.
  17. An actuator is a device that a robot can use to interact with the real world. Examples include: a sound device for making beeps or playing synthesized speech; a gripper on an arm for picking things up; and wheels (really the motors) to drive the robot around. ...
  18. An assembly of mechanical and electrical components that allow a robot to physically act upon itself or the environment.
  19. A device used together with radiant heat manifolds to control water flow through individual manifold branches. Actuators allow to use a single radiant heat manifold station to control multiple heating zones.
  20. A device which transforms an electric signal into a measured motion using hydraulic, pneumatic or pyrotechnic (explosive) action.
  21. The mechanism of a switch which operates the contacts.
  22. The active element of the printhead in which the pressure wave is generated to eject the ink.
  23. A device used to transfer motion from one object to another. An actuator activates a movement or a process.
  24. A pneumatic, hydraulic, or electrically powered device that supplies force and motion so as to position a valve's closure member at or between the open or closed position. [800-82]
  25. This is another name for the stepper motor of a C-band dish.  This motor moves the dish to different satellites.
