The challenge of creating reaction wheels for small satellites – with WITTENSTEIN cyber motor
A discussion of the technical and commercial obstacles that companies can face when producing attitude control innovation.
In this episode we speak with Christoph Weis from WITTENSTEIN cyber motor GmbH – a Germany-based manufacturer of advanced servo motor technology. We discuss:
- The company’s experiences bringing industrial expertise from other sectors into the space industry
- How commissioning and pre-sales simulation can help demonstrate value
- Insights from WITTENSTEIN cyber motor on the space industry of today, and predictions for tomorrow What technical and product performance characteristics were most important for the business’ product development.
WITTENSTEIN cyber motor’s reaction wheel
cyber® reaction wheel 2
A 30g and 20 × 20 × 20 mm3 reaction wheel designed for 1-8U satellites. The system provides 2.0 mN m s of momentum storage at a nominal voltage of 5V and can be used in different configurations. It also features vacuum-rated bearings and components resisting radiation up to 200 Gy.
