1. A control moment gyroscope which applies directional torque to a vehicle comprising:

  • a gimbal;

    gimbal support means mechanically attached to the vehicle which allows rotation of said gimbal about a gimbal axis;

    a rotor;

    means to magnetically levitate said rotor within said gimbal;

    means for inducing angular rotation of said rotor about a rotor axis which is normal to the gimbal axis;

    means for generating a magnetic field which induces torque on said rotor about an output axis normal to both the rotor axis and the gimbal axis, the torque on said rotor is transferred to the vehicle through said gimbal support means;

    sensing means to detect the proximity of said rotor to said gimbal; and

    rotation means connected to said sensing means for rotating said gimbal so as to follow precession of the rotor about the gimbal axis and avoid contact between the gimbal and said rotor.
