Actuators (EMA)

Integrated system for linear and rotary movement of flight controls and actuation systems.

Multiple features in a single unit.

Features and benefits

  • Reduced weight and volume

Our actuators are characterised by their high level of features integration.

  • Custom-designed to suit your application

Full in-house design and manufacturing of electrical motor, brake, clutch and position sensors, as well as all the parts and subassemblies.

  • Extensive range of power, torque and speed

Rotary Actuators provide from 0.2 Nm up to 5 000 Nm (3 700 lbs-ft), with speed ranges from 3 rpm to 1000 rpm and power from less than 1 W to 250 W.

Linear Actuators provide from 10 N up to 20 000 N (4500 lbs) servo thrust, a stroke up to 500 mm (20”) with speed ranges from 0.5 to 100 mm/second and power from less than 1 W to 2500 W.

We can also provide actuators able to sequence several rotary and linear movements.

  • Multiple electrical power inputs

DC brush motors for simple DC ON/OFF operation

Single or three-phase induction motor, also for ON/OFF operation

DC brushless motors for any type of operation, particularly servo-applications


Electromechanical actuator (EMA) integration

Our EMA design expertise can be used to integrate the following features:

  • Electrically controlled clutch
  • Electronic drive (embedding power, control and communication)
  • Mechanical back-up command
  • No back movement
  • Position sensor(s)
  • Power-off brake
  • Spur, conical, any type of epicycloid gears or worm gears
  • Tacho generator
  • Temperature sensors
  • Lead screws/ball screws/roller screws (linear actuators only)


Our EMA designs are used on air, land and sea. Our extensive range of applications include:

At Meggitt, we can provide you with an electromechanical actuator that is specifically designed for your application. To discuss what you need in more detail, please contact us.
