MECHANICAL ENERGY STORAGE WITH MAGNETIC GEARBOX Russian patent published in 2017 - IPC F16F15/305 H02K7/02 

FIELD: machine engineering.

SUBSTANCE: mechanical storage comprises a flywheel and drive in the form of a magnetic gear arranged coaxially and hermetically separated from each other enclosures. The flywheel is disposed within a vacuum enclosure. The rim of the flywheel is designed as a winding on the mantle surface of the flywheel tapes bonded magnets magnetized transversely to their width. Vacuum housing has an inner magnet, which is made by winding the same types of bonded magnets with oppositely magnetization relative to the rim of the flywheel. The power input-output device is a magnetic gear comprising a fast rotating shaft. The slow rotation shaft includes a hollow cylinder stator, comprising a magnetic circuit with teeth on its inner surface. The hollow cylinder stator is hermetically and mechanically connected to its one end to the frame via a non-magnetic ring. Hollow rotor and stator cylinders slow rotation comprise alternating ferromagnetic and non-magnetic elements directed along the axis of rotation.

EFFECT: reduction of losses during energy conversion.
