It is true that mechanical developments in the last ten years have changed dramatically. The technology we look at is electromechanical actuators.

What are electromechanical linear actuators? Well to start to understand the principles you look at how the actuator works. A linear actuator can basically be described as a motor that has bearings and a gear box. There’s a separate unit that controls the actuator in its movements,How Are Electromechanical Actuators Performance Rated? Articles whether it be moving in one way or the other but can only move laterally or as known to most as linearly, which then gives it its name which is quite logical. When these actuators are powered by either AC or DC – most of them do operate with DC, it’s relatively easy to identify an electro mechanical. There are different types of actuators and not all run off power. Air cylinders or otherwise known as pneumatic actuators use compressed air to generate the energy needed to move provide the movement power. In most cases these types of actuators are found in smaller applications because of their size and where they are used, maintain them can be awkward so these types of actuators are used. You’ll find them in things such as office equipment like scanner, copiers and printers. When looking at electromechanical linear actuators it's no secret that is has developed the production industries of today. Mass producing has also benefited as well as the packaging and export trade fraternities. Because there are various requirements for each load adjustment, electromechanical actuators are made in certain standard ranges with fixed specs but for instances where there is a unique function required, clients can have their own electro mechanical linear actuator custom made. They tend to assemble on order with such things as parts can be quite expensive and to have a range of unusual actuators lying around can be costly.When one looks at mechanical linear actuators and electromechanical linear actuators, there is a slight difference. Simply mechanical linear actuators are supervised in operation, and an example of this would be a fork lift. The actuators run from power but its functions are initiated by a control manned by an attendant. Some gantry systems are also included in this category. Electro mechanical linear actuators are virtually the same however, they’ve been fitted with an onboard control or receivers which interpret signals that will trigger a programmed function, an example of that would be gate automation. 12 volt linear electric actuators are motors running off AC but due to conditions they are designed to convert to DC for reasons including safety. The receiver connected to the electronics is programmed so that upon trigger or preprogrammed terminal, it pulls or pushes the linear arm without supervision. Elsewhere, electromechanical actuators are used together with a slider crank mechanism. This device has a master fix that has a crank joint angel that conducts reciprocating motion. These motor mechanisms are used in pumps mostly and pistons in cars are another example. In industries of actuators, electromechanical linear actuators and accessories in larger level operations are made by a place called Flowserve and they call them Limitorque actuators. They supply an international market with mechanical engineering science found in big industrial industries. No matter what you need, they can develop a solution for you.
