Actuator and accessory are mechanical or electro-mechanical devices that provide controlled and sometimes limited motion. Or positioning to be operated by electricity, by hand, or by various fluids such as air, hydraulics, etc.
Hardware devices that convert a controller command signal into a change in a physical parameter.
– The change is usually mechanical (e.g., position or velocity).
– An actuator is also a transducer because it changes one type of physical quantity into some alternative form.
– An actuator is usually activated by a low-level command signal, so an amplifier may be required to provide sufficient power to drive the actuator.
The two basic motions are linear and rotary. Linear actuators convert power to linear motion, typical for positioning applications. And often have a push and pull function.

This post is for those who are new to linear actuators and are looking for some guidance in choosing an actuator for a project.
In basic terms, a linear actuator is a device that produces motion in a straight line and is powered by an external energy source. This motion is commonly achieved with a rod extending and retracting or with a slider that moves on a track.
Linear actuators have a variety of applications: used in the healthcare sector, in the machine; industrial work applications, in a home; office automation or in solar tracking systems, and even in aerospace technology. These steps will help you in determining which linear actuator will suit your application.
Specify in your project what is the weight of the object to be moved or lifted?
Firgelli Automations carries a range of products from mini linear actuators with a force capacity of 15 lbs to industrial heavy duty linear actuators capable of moving forces up to 2000 lbs.
You have to answer this question “what is the distance that you want to move something in your project?” This is called the stroke length and it determines how far the linear actuator will move in one direction.
Firgelli Automations carries various linear actuators with strokes ranging from 1" up to 60".
How to measure a linear? The speed of a linear actuator is measured in distance per second. The specification sheet for a linear actuator will tell you the speed that the actuator is rated for. Generally, the higher the force required the slower the actuator will move. So that, you need to define does your project need to move fast or slow?
Not the same all, different types of linear actuators are better suited to certain projects.
With the technical specifications of your project worked out you can see which linear actuators will work with that parameters.
There are many kinds of actuators, the most common are the Rod-style actuators. It is a simple feature a shaft which extends and retracts. Track actuators are perfect for tight spaces where a sliding block is ideal due to its unchanging length whether extended or retracted. Or a column lift is ideal if you need an actuator with a long stroke in relation to its retracted size. And of course, there are actuators to lift your TV and drop down your TV.
Some linear actuators are used with manual controls, such as in the dental room, you easy to found the linear actuators in the dental chairs and require no other Positioner feedback with limited switches. There are some manufacturers even remove the limit switches by providing integrated free-form motion at the end of the stroke, such as the actuators shown on the right.
Hopefully, now you know the basics of linear actuators you will be sure to choose one for your next project.
If you have time should find out more creative uses for linear actuators and see how some of our customers are using them, check out the naman-tech pages on Instructables and YouTube.
Based on the source of Input Power actuators are classified into 3 groups:
These utilize pneumatic energy provided by the compressor and transform it into mechanical energy by means of pistons or turbines.
These transform the energy stored in the reservoir into mechanical energy by means of suitable pumps.
Electric actuators are simply electro-mechanical devices which allow movement through the use of electrically controlled systems of gears.
To finale this article, here we share a little bit about the new project: The hidden secret door in the Library that they using Linear Actuators to open and close the door. Have you ever heard about this secret project?
Absolutely here is the unique project, because of they wanted to slide out at door before it swings open??? This is needed because they wanted the door to appear as a hidden door when it is closed and still look like part of the wall.
– 2 actuators are used to slide the door mechanism away from the wall by about 4″ to ensure everything is clear.
– The third Linear Actuator is used to swing the door open by 90 degs.
If you can look at it in more detail then this concept is quite easy really for you. So we would recommend using an Arduino controller to program the sequence however if you wish you could just have 2 switches, one to operate the 2 actuators that slide out the door then one switch to operate the door that swings the door open 90 degs.
– The classic style linear actuator 4″ strokes
– The Arduino controller if desired to program the actuators to work in the correct order.
– The Actuator Brackets MB1.
