A linear actuator is a device that creates motion in a straight line, as opposed to rotational motion. It converts energy, often from electricity or hydraulic pressure, into linear movement. Linear actuators are commonly used in various applications, including robotics, manufacturing, and automation systems, to control the position of objects. These actuators can be found in different forms, such as electric motors, pneumatic cylinders, and hydraulic cylinders. They are essential in tasks that require precise movement, such as adjusting the position of solar panels or operating industrial machinery. Their ability to provide controlled motion makes them valuable in many industries.
