RW210 Series Reaction Wheel

The RW210 series reaction wheels are low mass, low power reaction control wheels, which allow CubeSats and other pico- or nano-satellites to control their attitude. These reaction wheels are specifically designed for 1 to 3U CubeSat platforms, and they are also used in the iADCS-series of attitude determination and control systems as well as the iACS series of attitude control systems.

The RW210 series of reaction wheels feature an internal fire-and-forget controller, which frees up the host processor’s workload.

The standard configuration features up to 0.1 mN.m torque, and an I²C interface. Different interfaces are available on request.

The RW210 is available with either 1.5, 3.0 or 6.0 mN.m.s of momentum storage in both directions of rotation.
