FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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.

Detailed explanation-2: -An actuator is a device that converts energy into some kind of “operation", such as linear movement, rotation, or bending. In addition to electricity, the input energy comes in a variety of forms, such as air (pneumatic) or oil (hydraulic) pressure, magnetic force from electromagnets, steam, and heat.

Detailed explanation-3: -Actuators use an energy source – such as electrical, compressed air, or hydraulic pressure – and a control signal that can be manual, an automatic electronic system, a fixed mechanical system, a software-run system or a robotic control system.

Detailed explanation-4: -Actuator Mechanisms Actuators are devices that convert some type of stored energy into motion. The stored energy is usually in the form of compressed air (pneumatic pressure), electrical potential, or liquid (hydraulic) pressure. It is typically stored within a sealed cylinder made in most cases from metal.

Detailed explanation-5: -An actuator is a device that produces a motion by converting energy and signals going into the system. The motion it produces can be either rotary or linear. An electric linear actuator is a device that produces a motion by converting energy and signals going into the system.
