What's the working principle of linear actuator?

A linear actuator is a device that converts rotational motion into linear motion.It consists of a motor,a lead screw or a ball screw,and a nut.

The motor is typically an electric motor that generates rotational motion. This rotational motion is then transmitted to the lead screw or ball screw through a coupling or a belt drive. The lead screw or ball screw has a threaded shaft with a helical groove that runs along its length.

The nut is attached to the load or the object that needs to be moved linearly. The nut has internal threads that match the threads on the lead screw or ball screw. As the lead screw or ball screw rotates, the nut moves along the screw, converting the rotational motion into linear motion.

The direction and speed of the linear motion can be controlled by controlling the rotation of the motor. By reversing the motor's rotation, the linear actuator can move in the opposite direction.

Linear actuators can be used in various applications such as robotics, industrial automation, automotive systems, medical equipment, and many others. They provide precise and controlled linear motion, making them suitable for tasks that require accurate positioning and movement.
