MicroEMA. Micro-Electromechanical actuator for aeronautical applications

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.
