Wikipedia

  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).

Webster Dictionary

    one who actuates, or puts into action

  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.
