The 3 mNms RW-0.003 from Rocket Lab is a Satellite Reaction Wheel that is designed for 1 U CubeSats and earth observation missions. It has a torque of 1 mNm and a nominal angular momentum of 0.005 Nms. This reaction wheel supports UART or I²C/SMBus command/telemetry interfaces and requires a supply voltage of 4.5-9.0 V. It comes with two control modes (speed or torque) and features a built-in control CPU. The reaction wheel has a radiation tolerance of greater than 10 krad dose and has diamond-coated hybrid ball bearings. It has a mass of less than 50 g and measures 33.5 x 33.5 x 17 mm.
