Abstract: The disclosed subject matter relates to a reaction wheel system for controlling and stabilizing a satellite or other spacecraft. The reaction wheel system includes a reaction wheel rotor and a containment structure stator including a plurality of contactor assemblies for securing the reaction wheel rotor when not in rotation and for electromagnetically inducing substantially frictionless rotation of the reaction wheel rotor.
