FIELD: electricity.SUBSTANCE: invention is related to electric energy storage units using kinetic energy. An advanced electric energy storage unit using kinetic energy contains a circular flywheel installed inside a body. The flywheel is rigidly pinned to a shaft. The shaft is installed in a rotating support so that it can rotate in the body freely. The device also contains conversion facilities. The conversion facilities are made so that they can convert electric energy supplied to the device input into mechanical energy accumulated by the flywheel and convert mechanical energy accumulated by the flywheel into electric energy at the device output. The device is symmetrical about the central plane perpendicular to the flywheel rotation axis. The flywheel disc is placed in the central plane. The above conversion facilities contain two rotor/stator units. These units are placed at both sides from the disc mounted inside a ring. The ring is formed by the flywheel. Each stator is connected rigidly to the body. Each rotor is connected rigidly to the shaft. The rotating support is represented by at least two support bearings. These bearings are placed symmetrically at both sides from the central plane and support the shaft ends.EFFECT: advanced storage device in comparison with the known engineering solutions, in particular the advanced device is characterised by a better balance, it considers mechanical, magnet and thermal conditions occurring in result of the device integrated mounting so that it could be used at rail vehicles.10 cl, 2 dwg |
