An actuator is a component of a machine that produces force, torque, or displacement, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system).

An actuator can work as a mechanical or electro-mechanical tool transforming energy, usually in the form of electricity, hydraulics, or pneumatics, into regulated motion or force.

Jul 18, 2025 · An actuator is a device that converts energy—typically electrical, hydraulic, or pneumatic—into motion. This motion can be linear or rotary, and actuators are critical in everything …

Feb 10, 2023 · An actuator is a device that receives an energy input and converts it into motion or force and is an essential component in many modern technologies and engineering fields. From robotics to …

Defined simply, an actuator is a device that converts energy, which may be electrical, hydraulic, or pneumatic, to mechanical output in such a way that it can be controlled. The quantity and the nature …

Sep 26, 2023 · Actuators are mechanical or electro-mechanical devices that generate controlled motion or positioning, operating through electrical, manual, pneumatic, or hydraulic power sources. They …

Actuators receive a source of energy and use it to move something. To put it another way, the actuator converts a source of energy into a physical-mechanical motion. A butterfly valve is operated by …
