What is a Linear Actuator?

One of the more important implements in the manufacturing world is the actuator, and while there are many different actuator styles, perhaps none are as useful as that of the linear actuator.

In simple terms, a linear actuator is a mechanical device that creates motion in a linear, or straight, line. This varies significantly from the circular motion that is created by conventional motors, thus making the linear actuator unique in its operation.

By connecting a linear actuator to a rotating electrical motor, operations are no longer limited to circular motion. In fact, it is the spinning of the electric motor that causes the linear actuator to move up and down.

How is a linear actuator used?
One of the most common implements where a linear actuator is used is in the operation of  high level windows. Situated high up in a home or  building these windows are designed to allow the building to breathe with out the use of mechanical ventilation.

Hot air will rise up to the highest part of the building and accumulate causing the inside temperature of the building to rise and rise.

Once the high level windows are opened the hot air will escape out through the high level windows which in turn will draw cooler more dense air in through the lower doors and windows.

This is called passive ventilation and promotes the movement of air in a built environment without the need for mechanical ventilation.
