subject: Dc Actuators As A Replacement For Hydraulic And Manual Systems [print this page] DC actuators are used when you need to move an object. Using these actuators you can push an object forward or backward, raise it, lower it or tilt it according to your requirements. These actuators are available in 12v or 24v versions, and you can use one that best suits your requirements. In the recent past, these actuators have emerged as a preferred option because they are much more efficient and convenient as compared to pneumatic, hydraulic and manual systems.
Operational basics of a DC actuator:
Once you invest in a DC actuator, you will certainly find yourself spending less time in its upkeep. At this point, lets understand what a DC actuator is. This actuation device can be used for activating assorted mechanisms. However, they are defined by the fact that they use direct current (Dc) as a power source to generate motion. And, the motion generated by such an actuator is along a single axis. This could be carried out through lead screws or gear trains for smooth and consistent operation. Speed levels in these actuators vary from one model to another.
Installation and use of a DC actuator:
Since DC Actuators function on direct current as a power source, it is vital that they are fitted with a step down unit. Versatility is a given with these actuators because they are widely used in sectors ranging from industrial automation uses, to robotics, to satellite actuation etc. Interestingly, home automation projects all over the world are increasingly making use of these actuators. For instance, you might find them being used in drop down TV panels, ventilation systems, sliding roofs over swimming pools, door controllers etc.
Commonly seen applications:
The electronics industry has been dependent on these actuators for a long time now. And this is especially true with the proliferation of compact consumer electronics such as digital cameras. Several lens control functions of a camera are controlled using these actuators. In the case of a camera, the actuator is powered using a battery.
Tips to choose the most appropriate actuator:
Based on the travel range of the actuator, you could choose an appropriate stroke range. This will ensure that you get the precise motion and the exact force that you desire to achieve. For instance, there are DC actuators that might extend up to an inch, or might have a reach that spans over several feet. Another deciding factor would be the pressure that you want the actuator to exert. For instance, if you want an actuator that can lift up large garage doors, you would need one that can exert a force of around 150lbs, approximately.
DC actuators are a very safe device if used according to the manufacturers guidelines. They involve the use of low currents, hence minimizing the risk of electrocution. Overall, they present you with low operating costs.
