An actuator is a device that activates a system based on the principle of dynamics. In fact, it is an American term for motor and it has numerous applications in hydraulic, pneumatic, electronic and allied streams of engineering.
Actuators facilitate steady and critical ratio of power and speed for optimum ergonomic solutions for a wide range of industrial and other complex operations of machinery, gadgets etc.
As compared to traditional electrical motors which function due to circular or rotary motion, linear actuators generate the thrust in a straight line. Hence they are extensively used in machinery, automobiles including gigantic earth moving and material handing machines, construction equipment and numerous hospital aids and gadgets. Read more
