Actuators
Actuators (EMA)
Integrated system for linear and rotary movement of flight controls and actuation systems. Multiple features in a single unit.
- Reduced weight and volume
- Custom-designed to suit your application
- Extensive range of power, torque and speed
- Multiple electrical power inputs
Linear Actuators
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
- Custom-designed to suit your application
- Extensive range of power, torque and speed
- Multiple electrical power inputs
Our actuators are characterised by their high level of features integration. Full in-house design and manufacturing of electrical motor, brake, clutch and position sensors, as well as all the parts and subassemblies.
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 linear movements.
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.
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:
- Flight controls (stroke limiting and trim actuators) for commercial aircraft
- Guided ammunition actuation
- Helicopter blade folding
- Load or system activation on military fighters
- Missile and torpedo fins
- Pilot seats
- Turrets on military ground vehicles
Rotary Actuators
Penlink supplied gears and actuators for use in the main rotation and pivot axes of the "turn table" and in the rotate and swivel axis of the electro-optics.
Important factors for the selection of gears are the high accuracy, low weight, the hollow shaft for implementing a slip ring and the high power density. Units are available in nine sizes with gear ratios of 30, 50, 80, 100, 120 and 160:1 offering repeatable peak torques from 9 to 1840 Nm.
