Actuator Systems

  1. Actuator Systems

Actuator Systems

Linear actuators are the core component of many production, machine and automation systems and as such; reliability, accuracy and repeatability are often the prerequisites of any actuator system. Here at Matara UK, we have the capability and expertise to design and manufacture a range of actuator system solutions, including pneumatic actuators, to suit the requirements of your industrial setting. Read on to find out more about actuator systems. 

What is an actuator system?

An actuator system consists of a number of key parts; all of which work together to move a load from one area to another. These key components are: 

  • One or numerous belt, ballscrew or electric linear actuators
  • Motors, gearboxes and control units to move the actuators along X,Y or Z axes.
  • Internal and external linear guide systems, using linear rail and carriages

These all work tougher to convert the control signal, powered with the hydraulic or pneumatic motor, to move items from one area to another. For any actuator system to perform consistently at its optimum level, it needs the correctly specified motor, gearbox, couplings and control system to accompany it. 

What are the key types of actuator

There are predominantly three main types of actuators, all of which are defined by the source of power that they use to control the movement of objects from one place to another. These are: 

Electric actuators

Electric actuators rely on electrical energy to move objects in a straight line. They operate by moving a piston back and force based on electrical signals and are often used for movements such as pushing, pulling, lifting, ejecting, clamping and descending. 

Hydraulic actuators

This type of actuator operates similarly to an electric actuator in that it generates a mechanical movement in a straight line. The difference here, however, is that hydraulic actuators do this through an unbalanced pressure that is applied with hydraulic fluid on a piston in a hollow cylinder that will lead to torque strong enough to move the object. 

Pneumatic actuators

Often considered to be one of the most cost-effective and simplest forms of actuator available on the market, pneumatic actuators work by using compressed air to create movement, either through extending or retracting a piston. However, pneumatic actuators also use a carriage that runs on a driveway or cylindrical tube to move an object. The retraction of the piston is either done through a spring or through the use of a fluid to build up pressure.

What should you consider when selecting an actuator system?

When you are looking to implement an actuator system within your industrial application, there are a number of key things that you must take into account. These are: 

  • The movement that is required, and whether it is linear or rotary
  • The energy input that you will be using
  • The level of precision that you need the actuator to achieve
  • The amount of force required to move the item from one area to another 
  • How far the object or item needs to move with the assistance of the actuator system 
  • The speed at which you want the actuated movement to move
  • The operating environment and any external factors that may affect the actuator systems operation such as corrosive environments
  • The mounting style you would like to implement. 

All of these factors are important when considering which actuator system is most suitable for use in your application. If you are interested in learning more about how to choose the correct type of actuator for your individual application, why not read our technical article on the subject?
