Title: REACTION SPHERE FOR SPACECRAFT ATTITUDE CONTROL
Abstract:
An electromagnetic stator 130 surrounds a spherical conductive rotor 140 to provide rotation of the rotor in a frictionless environment, as well as allows the rotor 140 to be driven in any axis. This eliminates the need for multiple reaction wheel assemblies that are only able to be drive about a single axis and also eliminates the use of gimbaled assemblies.
