About
The RW1500 is a reaction wheel specifically developed for satellite applications, providing precise attitude control. It is currently under development. Key specifications include an angular momentum of 25.0 Nms at nominal speed and a nominal rotation speed of 4000 rpm. The maximum commandable reaction torque is 0.2 Nm. The power interface operates with a supply voltage ranging from 22 to 37 V. Power consumption varies depending on the operational state: ≤ 2.5 W in standby (motor off), ≤ 30.0 W at nominal speed (0.1 Nm/max speed), and a maximum of ≤ 140 W (0.2 Nm/max. speed). Mechanically, the unit has a mass of ≤ 6.0 kg and a moment of inertia of 5.97e-2 kg m2 for its rotating mass. Its dimensions are 320 x 320 x 120 mm3. The RW1500 is designed to operate within a temperature range of -20 °C to +60 °C, with a start-up capability from -30 °C to +60 °C, and a survival temperature range of -40 °C to +65 °C. Data communication is handled via CAN/RS485 interfaces. The design lifetime is specified as > 15.5 years, with a storage time of > 6 years, which includes 1500 hours of ground operation.
