An actuator is a mechanical device that converts energy into motion, often used to control or move a system or mechanism. It is an essential component in many different types of machinery and equipment, from robotics and automation systems to aerospace and automotive applications.
Definitions
The term “actuator” is defined as a device that converts energy into motion or force, typically used to control or move a system or mechanism. The motion or force can be linear, rotational, or a combination of both, depending on the specific application.
Origin
The word “actuator” comes from the Latin word “actus,” which means “a doing” or “an act.” The term was first used in the context of machinery and engineering in the early 20th century, as engineers began to develop more sophisticated systems that required precise control and movement.
Meaning in different dictionaries
According to the Oxford English Dictionary, an actuator is “a device for converting energy into mechanical motion, especially one that controls or moves a system or mechanism.” Merriam-Webster defines it as “a mechanical device for moving or controlling something.” The Cambridge Dictionary describes it as “a device that produces movement or force in a machine or system.”
Associations
Actuators are commonly associated with robotics, automation, and control systems, where they are used to control the movement of robotic arms, conveyor belts, and other machinery. They are also used in aerospace and automotive applications, such as controlling the movement of aircraft flaps or adjusting the position of a car’s throttle.
