  • FLYWHEEL SYSTEM WITH STATIONARY SHAFT
    Publication number: 20240250593
    Abstract: A flywheel system including a rotor forming an aperture extending through a rotation axis of the rotor and a fixture including a shaft assembly for passing through the aperture of the rotor, wherein the rotor rotates about the shaft assembly. The shaft assembly includes a bottom support, a top support, a central rod connecting the bottom support to the top support, a plurality of stacked modules, each module forming an aperture for receiving the central rod, a top pre-tensioning nut affixed to a top end of the central rod, and a bottom pretensioning nut affixed to a bottom end of the central rod. The top pre-tensioning nut and the bottom pre-tensioning nut clamp the plurality of stacked modules between the bottom support and the top support.

  • Flywheel system with stationary shaft
    Patent number: 11923737
    Abstract: A flywheel system includes a rotor and a fixture. The rotor forms an aperture. The fixture includes a bottom support, a top support, and a shaft connecting the bottom support to the top support. The shaft passes through the aperture. The bottom support and the top support are outside opposite ends of the aperture. The rotor is configured to rotate about the shaft. A method for operating a flywheel system includes converting between rotational energy of a rotor and electrical energy in windings of a generator stator that is implemented in a stationary shaft passing through an aperture of the rotor, while the rotor is rotating about the shaft.
