MECHANICAL ELECTRICAL-ENERGY STORAGE Russian patent published in 2005 - IPC

FIELD: power supplies for electric vehicles, electric buses, and the like.

SUBSTANCE: proposed electrical-energy storage is, essentially, electrical machine that has frame carrying stator with stator coils, field coils, and shaft-mounted solid metal rotor. Stator windings whose cores are attached to frame are disposed over circumference with solid homogeneous-metal rotor possessing magnetic properties arranged in its center. Rotor has two opposing magnetic poles disposed on circumference and two projections made on rotor butt-ends. These projections mount field coils shielded by and fixed in position on end plates of frame. Magnetic sensors designed to control position of rotor magnetic poles relative to stator coils are disposed on one of end plates; permanent magnets insulated from rotor are installed at butt end of respective rotor projection.

EFFECT: enhanced power characteristics.
