Abrégé

The invention relates to a device (1) for an uninterrupted supply of energy and to an energy store (5) for kinetic energy, comprising a housing (13), a shaft (7) which has a non-rotatably connected inner rotor (8), and an outer rotor (11), in particular a drum-shaped outer rotor, which surrounds the inner rotor (8) at least in some areas and which is rotatably mounted relative to the shaft (7), said inner (8) and/or outer rotor (11) having at least one electric coil (9). The aim of the invention is to achieve a particularly compact design as well as a high stability and ease of maintenance. This is achieved in that the outer rotor (11), which is rotatably supported on the housing (13) in a mechanical manner on both sides, is held without mechanical support towards the shaft (7).
