The RW210 series reaction wheel is aimed at applications in 1 to 3 U CubeSats or similar platforms. It comes in three models that offer 1.5, 3.0 or 6.0 mN.m.s of angular momentum storage respectively in both directions. 0.1 mN.m of torque allow for rapid slewing operations with small satellites.

The small envelope of 25 x 25 x 15 mm includes a dedicated controller, offering simple fire-and-forget control to the user.


  • 1.5, 3.0, or 6.0 mN.m.s of angular momentum storage in both directions
  • Maximum torque: 0.1 mN.m
  • Fire-and-forget control
  • I²C compatible interface
  • Mass: 21 – 48 g


The RW210 reaction wheels have been flying on four missions ever since 2017.

The TRL of the RW210 is at 9.

We have currently three reaction wheels of the RW210 available, with different momentum storage, ranging from 1.5 mNms, 3 mNms to 6 mNms. If you are unsure which wheel fulfils your requirements best, please talk to us. We can recommend you the optimal wheel for your mission.

Our Flight models undergo, in comparison to Engineering models, vibration testing, microvibration testing and complete more thermal test cycles.

We offer acceptance testing of the Flight Model as well as qualification testing.
