A flywheel battery with double flywheel structure

The invention discloses a flying wheel battery with a dual-flywheel structure. The exterior of the axial middle of a rotary shaft is coaxially sleeved with an axial winding structure with a gap; flying wheels, which are coaxially and fixedly arranged on the rotary shaft in a sleeving manner, are arranged on the left and right sides of the axial winding structure respectively; the two flying wheelsare symmetrically arranged left and right relative to the axial winding structure; bearingless permanent magnet motors, which are coaxially and fixedly arranged on the rotary shaft in a sleeving manner, are arranged on the left side of the left-side flying wheel and on the right side of the right-side flying wheel respectively; the two bearingless permanent magnet motors are symmetrically arranged left and right relative to the axial winding structure; 12 circular annular grooves are uniformly formed in the plate surfaces on the left and right sides of a circular plate iron core of the axialwinding structure in the circumferential direction; central cylinders are all wound with axial winding coils; inner and outer circular annular grooves are formed in the wheel surfaces on one sties ofthe flying wheels; annular permanent magnets are embedded in the corresponding circular annular grooves; by adopting one axial winding structure, the axial movement of the rotary shaft is limited; andcompared with a single-fly-wheel structured flying wheel battery with the same radius, the rotational inertia of the flying wheel battery with the dual-flywheel structure is two times of that of thesingle-fly-wheel structured flying wheel battery, so that the flying wheel battery with the dual-flywheel structure is higher in energy storage.
