Reaction Wheel for ADACS 

The MAI-400 reaction wheels are offered as a complete, standalone reaction wheel assembly unit for CubeSats and NanoSat missions. The motor driver electronics, which includes an ARM Cortex CPU, reside on a 1.3” x 1.3” PCB mounted to the mechanical wheel assembly. This provides a compact, versatile solution for various attitude control needs. This single axis reaction wheel assembly can provide the necessary attitude control for all nanosatellites including CubeSats.
