FLYWHEEL ENERGY ACCUMULATOR |
摘要 |
In a flywheel energy accumulator comprising a vertical shaft rotatably supported in a vacuum housing by superconduct ive magnetic axial support bearings, lower and upper flywheels are mounted on the shaft in axially spaced relationship, a homopolar dynamic machine with a rotating magnetic field is disposed in the space between the flywheels and includes a stator supported in, or forming part of, the housing and a rotor mounted on the shaft so as to be disposed within the rotor, and the superconductive magnetic supporet bearings include a lower passive axial thrust bearing with an annular magnet disposed below the lower flywheel and an upper positive axial pull bearing with an annular magnet disposed above the upper flywheel and disc-shaped superconductors disposed adjacent the annular magnets such that both bearings provide magnetic forces jointly counteracting the gravity forces of the shaft, the rotor and the flywheels. |
