An aerogenerator comprising: - a fixed structure, - a wind turbine comprising a propeller provided with at least two blades and an axis securely extending from a hub of the propeller and mounted free in rotation on the fixed structure, to convert wind energy into mechanical energy, and - an electric generator comprising a rotor secured to the wind turbine and a stator secured to the fixed structure to convert the mechanical energy generated by the wind turbine into electrical energy, the rotor of the electric generator is fastened on the propeller so as to be at a distance from the axis of the wind turbine, the rotor comprises at least one element and the stator comprises at least one coil (420a, 420b) fastened on the fixed structure, such that each element passes proximate to each coil (420a, 420b) at each complete revolution of the wind turbine about its axis, characterised in that: said at least one element is based on a conductive material, and in that said at least one coil (420a, 420b) comprises at least one pair of coils, each pair of coils comprising: - a primary coil intended to be connected to an electrical energy source so that the primary coil generates a magnetic field when it is crossed by an electrical current supplied by the electrical energy source, and - a secondary coil intended to be connected to an electrical energy distribution network so as to inject into said network an electric current originating from the secondary coil and generated by disturbances of the field generated by the primary coil because of the passages of the elements based on a conductive material when the rotor rotates. -
