RW400 Series Reaction Wheel

The RW400 series reaction wheel is a low mass, low power reaction control wheel, which allows CubeSats and other small platforms to control their attitude. The wheel was specifically designed for 6 - 12U CubeSat platforms, and is also used in the iADCS400-series of attitude determination and control systems.

It features an internal fire-and-forget controller, which frees up the host processor’s workload.

The RW400 is available with either 15, 30 or 60 mN.m.s of angular momentum storage in both directions of rotation.

All versions feature 2 mN.m of torque (optional up to 5 mN.m) and an I²C compliant interface. Different interfaces are available on request.
