Sub-systems

ADR has developed new equipment and sub-systems such as the servomotors, motorised bearings and positioners to meet new technological requirements. ADR provides a complete electromechanical function based on expertise and experience going back more than 25 years in the high precision fields. 3-Axis Positioners in Carbon Composite (G3AC) The carbon composite positioner has been developed for the new defence and aeronautics telecommunications markets that demand high positioning accuracy and stable mechanical behaviour in time. Servomotors and Motorised Bearings The range of servomotor and motorised bearings has been designed with the aim of reducing mass and overall dimensions as well as achieving high rigidity of the shaft. Servomotors have very high angular precision and can evolve in demanding mechanical and vibratory environments. The servomotor and the motorised bearings bring the following benefits: • A hollow shaft for central routing of equipment and connections; • A high precision angular position sensor which is integrated into the servomotor range; • Motorised bearings architecture and flat, compact, so-called pancake-shaped servomotor; • High axis velocity thanks to its direct drive architecture and low inertia; • High torque and high reliability are delivered by the Brushless motor.
