Key highlights
The O.C.E. Technology RW250B Momentum Wheel 25Nms B is designed for satellites operating in MHigh Earth Orbit(HEO),and Medium Earth Orbit (MEO). It consists of internal wheel drive electronic, which could work as momentum flywheel or reaction flywheel. Its operational mode is torque-mode. RW250B is primarily used in meteorological satellites.
Applications
Suitable for meteorological satellites High Earth Orbit(HEO), and Medium Earth Orbit (MEO).
Key features
- Welding sealed
- Designed for excellent environmental adaptability by adopting analog electronic
- Internal step-up electronic
- Long lifetime
