cyber® reaction wheel 2 for pico & nano satellites
The compact cyber® reaction wheel 2 is especially designed for attitude control used in pico or nano satellites. Due to its cube shape with integrated electronic control it can be used in several configurations. The reaction wheel is provided with vacuum-rated bearings and components resisting radiation terms up to 200 Gy. Profiting from the experience of WITTENSTEIN cyber motor in the field of precise small permanent magnet motors and ZFT in the field of reliable space electronics and software engineering.

Extremely compact in a square space of 20 x 20 x 20 mm, the reaction wheel is especially designed for rough space conditions. The square construction makes space-saving integration possible and, with its low torque / weight ratio it provides maximum flexibility in the application. The efficiency, robustness and compactness characterize the reaction wheel.
For a 360 ° alignment of the satellite, the reaction wheels can be positioned in various arrangements.
