About
The Reaction Wheel RW100 is a recent development from ASTROFEIN, building upon the design of the RW90. It is specifically optimized for production processes in constellation applications, combining existing wheel technology with an automotive approach for efficiency and reliability. This reaction wheel is designed to provide attitude control for small satellites, offering an angular momentum of 0.4 Nms at its nominal speed of 6000 rpm. It can deliver a maximum commandable output torque of 0.02 Nm across its entire speed range. The device operates on a supply voltage of 18 to 34 V, with power consumption ranging from ≤ 2 W in standby mode (motor off) to 20 W at maximum torque/speed. Mechanically, it has a mass of ≤ 0.8 kg and dimensions of 100mm x 100mm x 60mm. It features a moment of inertia of 6.52×10^-4 kg m^2 for its rotating mass. The RW100 is designed for operation in temperatures from -20 °C to +60 °C, with a start-up range of -30 °C to +70 °C and a survival temperature range of -40 °C to +75 °C. It uses an RS485/RS422 data interface and boasts a design lifetime of > 7 years in Low Earth Orbit (LEO), with a storage time of > 3 years (including 240 hours of ground operation).
