This happens because a linear motor is modified in such a way as to the only move in linear directions rather than rotational ones.
Electric linear actuator how it works.
A linear actuator is a piece of equipment that turns rotational motion into linear motion through the application of linear force.
The advantage of these actuators is that an operator gains complete control over an object.
So the big question is how does a linear actuator work the linear motion is created by using a screw or lead scew as they are more correctly called.
The screw turns either clockwise or counter clock wise and this causes the shaft which is basically a nut on the screw to move up and down the screw as the screw turns.
These are the two most important electric linear actuator parts.
The basic working principle of electric linear actuators is to convert the rotary motion into a linear motion.
