What are linear actuators and how do they function?

Linear actuators are devices used to create linear (straight line) motion in various applications. They convert rotational motion from a motor (typically a servo motor) intLinear actuators o linear movement. This is achieved through mechanisms such as screwdriven or belt driven systems.

In this video, Henry Gilland, an automation specialist at ES&E, provides an overview of linear actuators, explaining their function and applications. He contrasts traditional pneumatic and hydraulic actuators with electric actuators, highlighting their energy efficiency, system simplicity, and reduced contamination risk. The video also details the two main types of linear actuators—screwdriven and belt driven—each suited for specific applications like high precision or high-speed movement. Linear actuators are used across industries like pharmaceuticals, food, beverage, and automotive, making this understanding valuable for anyone involved in automation.
