Noliac Group Technology, Products and Applications

Noliac is specialized in a high degree of customization

• PAD – Piezoelectric Actuator Drive• Developed by Siemens 2000 - 2008• 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

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.
