Patent ID: 8860239

Claim:
A wind or water energy installation for production of electrical energy comprising at least one propeller and at least one generator, the generator including a rotor, a stator having flux-guiding material, and at least one magnetic circuit producing a magnetic flux; wherein the at least one magnetic circuit comprises at least one stator-side magnet and at least one stator-side coil through which at least a portion of the magnetic flux of the stator-side magnet flows, and the magnetic circuit is closed by the rotor; wherein on its surface facing the stator, the rotor has a magnetic reluctance (Rm), which is dependent on its respective rotation angle, such that the magnitude of the magnetic flux in the at least one stator-side coil is dependent on the respective rotation angle of the rotor, and varies during rotation of the rotor; and wherein the stator has an inner face facing the rotor and an outer face facing away from the rotor, the at least one stator-side magnet being embedded in and completely surrounded by the flux-guiding material of the stator such that the at least one stator-side magnet is separated from the inner and outer faces of the stator by the flux-guiding material.
