About
The RWT150 is a reaction wheel specifically designed for small satellites, serving as an upscaled version of the RW150. It is currently under development. This component is crucial for attitude determination and control systems (ADCS) in spacecraft. Key features include a nominal angular momentum of 1.0 Nms at its nominal speed of 6000 rpm, and a nominal reaction torque of 0.1 Nm, which is the maximum commandable deliverable output torque across its entire speed range. The RWT150 operates with a supply voltage of 18 to 34 V, with power consumption varying from ≤ 2.5 W in standby (motor off) to ≤ 7 W at steady state, and a maximum of 7 years in Low Earth Orbit (LEO) and a storage time of > 3 years, including 240 hours of ground operation.
