Linear electric actuator is actually a motor where mechanical motion is obtained from electrical energy. The discovery of the principle behind this technology in itself is a great finding in the domain of electro-mechanical force. It has helped to achieve more for various industries with its great functions. It reduces efforts, time by nullifying the intermediate transmission efforts. It produces a linear movement which can be utilized for various purposes.

Not only electrical energy, a linear electric actuator can be brought into functioning by various other forms of energies, like hydraulic, pneumatic, mechanical etc. Scientists are continuously trying to make better use of actuators, which is a good sign for the future. There are various fields where linear electrical actuators are an unavoidable part. Efforts are being made to explore more usage for these actuators, like the medical field etc.

The name linear actuator signifies that a linear movement is involved in this type of motor. While using such an actuator, one needs to consider its speed, stroke length, and also the load rate of the actuator. A perfect combination of all these factors makes an actuator useful enough for a purpose. Programmability of the actuator is also an important that should be considered here.

Coming to the functioning of a linear actuator, actually different types of actuators work differently. However, their basic principles of working are somewhat similar to each other. An actuator works as a motor which rotates a screw and is synchronized by a timing belt drive. Actuators are there which use a work gear drive or a direct drive.

In an actuator, the rotating screw pushes a screw nut into the screw and as result the rod come out. And then the screw rotating in the opposite direction retracts the rod back to its original position. Well, this is the basic functioning of a linear actuator. There are used in different ways in different cases.

An actuator actually works as a controller of work motion. Now a day, the actuators which are used for controlling motion of a system are controlled by computers. These are mostly used in robotics and also for factory automation.
