About
The Reaction Wheel RW150 is a key component for attitude control in small satellites. It incorporates integrated wheel drive electronics with latch-up protection, ensuring robust operation. The device offers different operation modes for speed and acceleration, utilizing model-based controllers to achieve precise control. It is characterized by high torque and speed stability, resulting in low operational noise. The RW150 provides extensive housekeeping data, including speed, voltage, current, and temperatures, allowing for comprehensive monitoring. It features internal compensation for friction and time delays, enhancing its accuracy and performance. The mechanical design, coupled with high levels of alignments and balancing, ensures low emitted vibrations. The RW150 is designed for a design lifetime of over 7 years in Low Earth Orbit (LEO) and a storage time of over 3 years (including 240 hours of ground operation).
