What is a Linear Actuator?
An electrical linear actuator is a device that translates rotational motion, from an enclosed motor, into linear pushing/pulling motion from the shaft [2]. They range in several variables but, most importantly, different linear actuators have different weight limits and shaft lengths. They are versatile, efficient, safe, easy to install, and easy to use. On top of being easier to install, linear actuators are also much cheaper and compact than hydraulic or pneumatic systems. They essentially consist of a DC or AC motor, gears, and a lead screw with driving nut that pushes the shaft in and out [2].
