ABSTRACT:
A flywheel assembly has a base and a flywheel rotatable with respect to and in contact free relation with the base. First and second annular yokes are secured to the base coaxial with the flywheel, and coupled to each other by radially extending control poles. Control coils are wound around the poles. An annular magnet is mounted on the first yoke, coaxial therewith, and a third annular yoke is mounted on the magnet. An outer cylindrical yoke is secured to the flywheel at the outside of the first yoke, and an inner cylindrical yoke is fixed to the flywheel at the inside of the second yoke. The cylindrical yokes are coupled to each other by an annular yoke. A magnetic flux from the magnet flows through the magnet, third yoke, outer cylindrical yoke, first yoke, and the magnet, thereby controlling the axial position of the flywheel. A control flux produced by one of the coils flows through a control magnetic path which passes through one of the poles, first yoke, outer cylindrical yoke, annular yoke, inner cylindrical yoke, second yoke and said one of the poles, and extends radially with respect to the rotational axis of the flywheel, thereby controlling the radial position of the flywheel.
