ABSTRACT:
A flywheel apparatus of the invention has a base and a rotor. The rotor is supported by a magnetic bearing. The magnetic bearing has a first annular plate member of a magnetic material, a second annular plate member of magnetic material radially opposing the first annular plate member so as to define a first annular gap, and at least two magnetic circuits formed between the first and second annular plate members as the first annular is a common magnetic path. The apparatus further includes solenoids for changing, at a plurality of positions along the circumferential direction of the first annular magnetic gap, the density of the magnetic fluxes passing along the common magnetic path.
