  1. Actuator

    An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover". An actuator requires a control device (controlled by control signal) and a source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic, or hydraulic fluid pressure, or even human power. Its main energy source may be an electric current, hydraulic pressure, or pneumatic pressure. The control device is usually a valve. When it receives a control signal, an actuator responds by converting the source's energy into mechanical motion. In the electric, hydraulic, and pneumatic sense, it is a form of automation or automatic control. The displacement achieved is commonly linear or rotational, as exemplified by linear motors and rotary motors, respectively. Rotary motion is more natural for small machines making large displacements. By means of a leadscrew, rotary motion can be adapted to function as a linear actuator (a linear motion, but not a linear motor).


  1. actuator

    An actuator is a device that converts energy into motion. It controls a system or mechanism by moving or controlling it. This device is typically powered by pneumatic pressure, hydraulic fluid pressure, or electric current. Actuators are key components in a wide range of mechanical systems and devices, and they also play a critical role in robotics, industrial processes, and many other applications.

Webster Dictionary

  1. Actuatornoun

    one who actuates, or puts into action


  1. Actuator

    An actuator is a type of motor for moving or controlling a mechanism or system. It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion. An actuator is the mechanism by which a control system acts upon an environment. The control system can be simple, software-based, or a human or other agent.

Examples of actuator in a Sentence

  1. Ryan Goodwin:

    The new device has a magnetic actuator, so it’s an expandable rod so once it’s implanted it’s not necessary to go back in with another operation to lengthen it, simply using a magnetic actuator can actually lengthen the rods slowly through the patient’s skin without having to do an operation.
