Actuators can create a linear motion, rotary motion or oscillatory motion. That is, they can create motion in one direction, in a circular motion or in opposite directions at regular intervals. Hydraulic and air cylinders can be classified as single-acting cylinders, meaning that the energy source causes movement in one direction and a spring is used for the other direction. Alternatively, these cylinders can be double-acting cylinders, meaning that the energy is used in two directions.
Types Of Actuator-
There are two types Of Actuator – Hydraulic actuator & Electric Actuator
A hydraulic actuator is a hydraulic cylinder or hydraulic motor that converts hydraulic power into useful mechanical work; the mechanical motion produced may be linear, rotary, or oscillatory.
A linear actuator is an actuator that creates motion in a straight line, as contrasted with a circular motion of a conventional electric motor. produce linear motion; many other mechanisms are used to provide a linear motion from a rotating motor.
An Electric actuator is a type of motor that is responsible 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 a mechanism by which a control system acts upon an environment. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), a human, or any other input.
