Reaction Wheel 250


The RW 250 is a smart reaction wheel for Small and Micro Satellites with integrated wheel drive electronics, different operation modes for speed and acceleration using model based controllers, high torque and speed stability (low noise), internal compensation of friction and time delays, provides extensive housekeepings (e.g.: measured and estimated speed, voltage, current, acceleration reserves etc.), various protective and monitoring mechanisms for: Voltage and current, Temperature and Data processing and low level emitted vibrations, due to the mechanical design and the high level of alignments and balancing.
