  • Flux-switching dual excitation electrical machine
    Patent number: 7868506
    Abstract: Flux-switching electrical machines. In particular, a flux-switching electrical machine having a stator and a rotor. The stator has permanent magnets, armature windings and excitation windings, and the rotor has no winding or permanent magnet but includes a plurality of flux-switching teeth. The stator is generally formed by a succession of elementary cells, each cell being intended to interact with only a single tooth of the rotor at a time. Each cell includes one of the permanent magnets; a first slot for at least partly housing one of the excitation windings at least; and second slots for housing one of the armature windings.
