ENERGY ACCUMULATOR Russian patent published in 2012 - IPC H02K7/02 H02K7/09 H02K51/00 F16F15/315 

FIELD: electricity.

SUBSTANCE: accumulator contains a vacuumised housing, a fly-wheel in the form of a vertical cylindrical tubular rotor with a motor generator set with a stator and a drive disc. The support system is composed of a needle support bearing with a bearing socket in the lower part and a magnetic bearing with a permanent magnet in the upper part of the rotor. The supports rotary elements are attached to the partitions installed inside the rotor tube at a certain distance from its butt ends. The horizontal plane passing through the boundary of interaction between the support rotary and non-rotary elements cross the rotation axis in the unit of the rotor axle bend shape at the operating rotation rate. The accumulator housing is installed into an accumulator assembly.

EFFECT: reduction of aerodynamic losses in the vacuumised housing and losses in the rotor support units.
