In a flywheel energy accumulator including, in a vacuum-tight housing, a vertical shaft with a rotor of an electric motor/generator arranged in the axial center of the shaft and flywheels mounted on the shaft at opposite sides of the rotor, the electric motor/generator and the flywheels are included in modules, each with a housing ring, which are mounted on top of one another and receive bearing modules including support discs mounted between, and adjacent, the housing rings with superconductive magnetic bearings disposed in the center thereof around the shaft for supporting the shaft with the flywheels and the rotor. The number of superconductive bearings is twice the number of flywheels. The bearing module discs between adjacent flywheels have upper and lower superconductive magnetic bearings and the bearing modules at the axial ends of the shaft and adjacent the rotor carry each only one superconductive magnetic bearing so that the number of superconductive magnetic bearings is greater, by two, than the number of flywheels.
