Concepts for the Actuation System of the Spacecraft Technology Vehicle SHEFEX 2

Concept of the actuator
The actuator is the key component of the actuation system. It must operate against high loads (torque, bending moment) and sustain the thermal loads. We selected a brushless DC motor which acts on a spindle-lever link. The fin axis has ceramic ball bearings.
