The most simple mechanism that continues to be demanded among customers for home automation is a linear actuator. Although its construction is not very complicated, still we can find today a great variety of linear actuators for different loads, purposes, and projects on the market.

To learn more about the types and voltage of the most popular models for your future home automation project look here and be aware of key specifications connected with this mechanism. Before finding out the major types of linear actuators let’s reveal more details about their design features.

Standard and small design

Typically, a linear actuator includes the motor as a separate cylinder fixed to the side of the mechanism, either parallel or perpendicular to the actuator. Sometimes the motor can be located close to the end of the drive. The drive motor is often designed with a rugged drive shaft that is linked with a drive nut or screw.

Compact variants of linear actuators use specially constructed motors that attempt to keep the motor and actuator very as minimal as possible.

 

The internal diameter of the motor shaft can be enlarged so that it can be hollow. Thus, the drive screw and nut can take up the center of the motor without the necessity for additional transmission between the motor and the motion screw.

 

Similarly, a motor may have a very small external diameter, but instead, the pole surfaces are spread along the length, so the motor can maintain very high torque when installed in a small-diameter environment.

Four Main Types of Linear Actuators

Currently, there are three major kinds of linear actuators that can be appropriate for home or industrial projects. Generally, all these mechanisms are very common. They can be of diverse shapes, styles, sizes, and price labels. More information about each of them you will discover below.

Electric

This one is probably the most popular in terms of implementation for home automation and they can be of a micro size and big ones. When compared with others, these actuators are more cost-effective and are typically applied for projects that need relatively slow, settled, and exact movement. One more benefit of the following actuators is that you can choose from various control options the most comfortable for you.

 

Pneumatic

This kind of device works with the help of compressed air to start moving. They are not as precise as electric actuators are but they are perfect for projects that need only two positions in the process of operation. Speaking about the price, it is commonly a bit expensive.

Hydraulic

To start the movement hydraulic actuators use a special hydraulic fluid under pressure. They are not very quick in the process of work but are great for commercial environments and manufacturing where the related specialists deal with both precise and powerful movement.

 

Vacuum actuators

These actuators are almost the same as the pneumatic ones but they use a different power for work, for example, vacuum actuators use vacuum produced by the related pump. They can be successfully applied in automobiles and many industrial applications.
