RW222 Reaction Wheel

The RW222 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.
