CubeSat Reaction Wheels RW0 / 4RW0

The minimum order quantity for RW0 subsystem is 4 pieces.

NanoAvionics has designed reaction/momentum wheels (RW), offered either as a separate component (RW0) or as an integrated four-reaction-wheel redundant 3-axis control system (4RW0), to enable precision pointing of the satellite bus.

Reaction wheels include DC brushless motors assembled in sealed housing providing no particle emissions and preventing contamination of peripheral devices.
