The RW400 series reaction wheel is aimed at applications in 6 to 12 U CubeSats or similar platforms. It comes in three models that offer 15, 30 or 50 mN.m.s of angular momentum storage respectively in both directions. Up to 12 mN.m of torque allow for rapid slewing operations with small satellites.

The small envelope of 50 x 50 x 27 mm includes a dedicated controller, offering simple fire-and-forget control to the user.


  • 15, 30, or 50 mN.m.s of angular momentum storage in both directions
  • Maximum torque: 12 mN.m
  • Fire-and-forget control
  • I²C compatible interface
  • RS422/RS485 interface
  • Mass: 155 – 375 g


The RW400 reaction wheels are scheduled to be part of an iADCS400 which will be delivered to a client soon.

The TRL of the RW400 is at 7.

We have currently three reaction wheels of the RW400 available, with different momentum storage, ranging from 15 mNms, 30 mNms to 50 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.
