What is an actuator?

Actuators are the mechanical component of a machine or system which provides movement. They can provide either rotary or linear motion and are typically split into 3 main categories based on the type of power they employ for propulsion.

  • Pneumatic
  • Hydraulic
  • Electric

Pneumatic  – Uses compressed air under pressure to drive a shaft to create movement. Typically very durable and suitable for environments where ignition or electricity is a challenge or a danger to use. The accuracy and efficiency can be lower than electric and hydraulics alternatives.

Hydraulic  – uses fluid under pressure in a similar way to pneumatics. Typically used in very high force applications or where the compressor or motor is required to be housed far away from the actuator. Also susceptible to leaks and inefficiencies. Hydraulic fluid can damage environmental systems or consumable products.

Electric  – An electric actuator is a device that creates smooth motion control by utilising an electrical motor to generate the required force. Electric actuators typically convert the rotations in gears into straight or linear motion for precise repeatability in movements such as lifting/lowering. Electric linear actuators are more accurate and efficient than conventional hydraulic and pneumatic actuators. An electrical actuator is commonly utilised in the operation of highly accurate movement, lifting, sealing, pressing, closing and opening. This means they can be found in applications as diverse as medical devices, manufacturing automation, submarines, food processing, power generation, testing & simulation, control valves and many more. If it needs to be moved accurately, efficiently and dependably, then electric actuators are a great solution.

Electrical actuators may be further subdivided depending on how the electrical power is deployed to create movement.

Ball screw  – ball bearings are fed around a thread form with matching grooves to the ball bearing form. These bearings transmit the force which is converted to motion. Ball screws are typically used where the duty cycle, force and speed is low. They can suffer from brinelling and lower life expectancies.

Roller Screw – Multiple roller screws with helical threads are assembled in a planetary system around the screw threaded shaft. The high number of contact points means high torque, power and longevity. This makes roller screw actuators the ideal choice for applications with continuous or heavy load cycles.

Inverted Roller Screw – the shaft and screw are inverted in this design. The nut has a threaded inner diameter and the nut is made to the length of the stroke. The design makes the actuator more compact as the transmission is integrated in the rotor of the servo motor.

Tubular Linear Actuators  – Contactless direct-drive motion without any contact between forcer and shaft. Lower force than roller screw but with no wear or need for lubrication or maintenance. Ideal for use in food production and sterile environments.

Linear or rotary actuator?

Rotary actuators rotate from open to closed. The electromagnetic power is generated from the motor, which causes the components within the rotary actuator to rotate. A circular shaft or a table can be used as the rotary element that provides the rotary motion.

In contrast, Linear electric actuators open and close utilising pinch, globe, diaphragm, gate, or angle valves. Linear actuators are often utilised when tight tolerances are required. Linear electric actuators have the load connected to the end of a screw that is either belt or gear driven.
