ABSTRACT:
A gyro bearing and caging mechanism in which a spherical gyro rotor is driven by an induction motor with bearing surfaces between the rotor and stator having a magnetic fluid that is held in place at discrete positions around the circumference of the rotor by permanent magnets imbedded in the spherical rotor and a movable caging plate with magnets in a surface thereof and magnetic fluid between surfaces of the caging plate and a top surface of the rotor for caging the rotor.
