MicroEMA. Micro-Electromechanical actuator for aeronautical applications




- Client: Internal development of SENER
- Country: Spain
- Start date: 2006
- Ending date: 2010
Development, design and manufacturing of a micro electromechanical actuator for aeronautical applications tested and flight qualified.
The lightness and compactness of the resulting actuator, allows integrating them inside the wing / flap boxes, avoiding thus extra fairing. It has a high power density: 120 W. of peak power within 60x90x150 mm dimensions.
EMA Health Monitoring System:
- SENER’s Health Monitoring and Management System for EMAs monitors different operating parameters of the actuator in real time.
- It provides failure detection, diagnostic, and prognostic information to the platform and its maintenance operators.
- Proactive maintenance strategies make use of the data in order to repair or replace the EMA before failure.
- Main features:
- Application: Secondary Flight Control
- Output movement: linear
- Motion transformation: Roller screw
- Actuator mass: 2.1 Kg
