About
The RW6000 is a reaction wheel developed by ASTROFEIN, intended for use in satellites for attitude determination and control. It is currently under development and is noted as the largest wheel produced by ASTROFEIN to date. The device offers a significant angular momentum of 100.0 Nms at its nominal speed of 4200 rpm, and a nominal reaction torque of 0.2 Nm, which is its maximum commandable reaction torque. It operates with a supply voltage ranging from 23 to 34 V. Power consumption varies depending on the operational state: ≤ 5.0 W in standby (motor off), ≤ 30.0 W at nominal speed, ≤ 75 W at 0.1 Nm/max. speed, and a maximum of ≤ 150 W at 0.2 Nm/max. speed. The RW6000 has a mass of ≤ 12.5 kg and a moment of inertia of 2.274e-1 kg m2 for its rotating mass. Its dimensions are 446 x 442 x 149 mm3. It is designed to operate within a temperature range of 0 °C to +60 °C for both operation and start-up, with a survival temperature up to +65 °C. Communication is handled via a CAN data interface. The design lifetime is specified as > 15.5 years, with a storage time of > 6 years, including 1500 hours of ground operation.
