  • Patent number: 10931164
    Abstract: The disclosed device is for storing energy by means of a flywheel. The device comprises a solid rotor having embedded permanent magnets along its outer surface, with flywheels attached at each end. The rotor is suspended by magnetic bearings within a housing. The housing comprises electromagnets that are sequentially charged in order to cause the rotor to spin due to the interaction of the electromagnets with the facing permanent magnets on the rotor. The spinning of the rotor causes the flywheels to spin, which results in the storage of rotational energy. The flywheels, which include magnets, turn through sets of coils on either end of the housing, thereby operating as an electrical generator to convert the flywheel rotational energy into electrical energy output from the device.

  • Patent number: 10700583
    Abstract: An induction machine with integrated magnetic gears is disclosed. The machine comprises two rotors and two stators. An outer stator has ferromagnetic material, producing a rotating magnetic field with a defined number of pole pairs synchronized with a supply frequency. A high speed rotor has ferromagnetic material and a combination of rotor bars and permanent magnet pole pieces selected so that the permanent magnet pole pieces do not interact with the outer stator magnetic field. The high speed rotor rotation is asynchronously coupled to the outer stator magnetic field. An inner stator has ferromagnetic steel segments that modulate the field produced by the high speed rotor permanent magnets. A low speed inner rotor has ferromagnetic material and permanent magnet pole pieces, the low speed inner rotor counter-rotating to the high speed rotor. The low speed inner rotor is synchronously coupled to the high speed rotor using modulation harmonics.
