Company Presentation January 2011

Noliac Group Technology, Products and Applications Noliac is specialized in a high degree of customization

PAD – Piezoelectric Actuator Drive Developed by Siemens A partner needed for commercialisation Noliac A/S acquired the PAD technology from Siemens AG in 2010 –Patents –Fully equipped test laboratories –PAD prototypes and demonstrators –Training of engineers Motor currently being developed for Siemens Piezoelectric Actuator Drive -PAD

The displacement is generated by the piezo components –Signals with 90° phase Piezoelectric Actuator Drive -PAD

Servo-controlled System PAD electronics PAD motion control PAD drive CAN, Profi-Bus, Gearbox Position sensor Torque sensor E-Motor Motion control E-Brake Electronics CAN, Profi-Bus, PAD System PAD – Reduced Complexity

PAD - Characteristics Dynamics High acceleration and deceleration without e-brake (low inertia) Slow and precise motion possible (0 to 60 rpm) Revolution independent of load Scalability Scalability in terms of power, relative speed and torque Synchronization of multiple PADs possible Torque / load sensing Smart load sensing without torque sensors High torque without gearbox / no backlash (typ. 6,5 Nm) Overload protection Others No power consumption when holding a load Function not affected by strong magnetic fields or radiation No magnetic stray fields Precision Positioning accuracy and repeatability (< 2 arcseconds) without encoders/decoders No gearbox required / no backlash No overshooting

Special conditions of relevance in relation to ITER: High temperature (up to200°C) : High temperature is generally not a problem. Both the housing and the actuators should be able to cope with high temperature, and the wiring can be insulated. Vacuum: PAD should be capable of withstanding Ultra High Vacuum (UHV) up to 10^3 Pa. Magnetic field: PAD has so far been successfully tested at 1,5T, but should be able to cope with a stronger magnetic field (5-8T). Radiations: Generally not a problem. The resistance will depend on the materials selected for the PAD unit.
