The Pros and Cons of Electric Actuators
A linear actuator is a device that turns non-linear motion, or movement that does not go back-and-forth, into linear movement, or motion that does go back-and-forth. There are different varieties of linear actuators, and they range in size, power, and use. The specific type called a DC actuator, for example, is usually used in conjunction with a DC power source in order to function properly. We often see these kinds of actuators in smaller devices that require batteries. The DC actuator is part of a larger family of linear actuators called electric actuators.
Electric actuators are employed in many industrial settings, and they come in different variations. There is the DC actuator, which I already mentioned, and where there is DC, there is AC. The AC actuator is similar to the DC actuator; of course, it just relies on a different type of electricity to work. Where the DC actuator requires a DC motor for its source of power, the AC actuator uses an AC motor.
The great thing about actuators is they make our lives much easier. They fit into places we cannot and they make us safer since they can be used in situations that would normally be pretty caustic for a person. Electric actuators do have their fair share of drawbacks, though. For example, like any electrical system, there is always the risk of fire. So if you want to use an electrical actuator you have to take measures to prevent against fire. Also, electric actuators are not always capable of producing the same amount of power as other types of actuators. As always, though, the advantages of the electric actuator may outweigh some of the structural concerns. Because they are electric you can run them from a variety of power sources; if you decide to power them using solar power, then you can feel secure in the fact that you are using clean energy. Another advantage is that if you use an electric actuator you can use a remote control for it. Ultimately, like any device, you have to decide for yourself if the benefits outweigh the cost.
