Abstract

Generador eléctrico y aerogenerador que comprende dicho generador eléctrico.#La presente invención se refiere a un generador eléctrico y al aerogenerador que comprende dicho generador, donde el generador comprende un rotor donde la sección radial de su corona es variable a lo largo de su perímetro debido a que la corona del rotor comprende unos rebajes dispuestos en la cara de la corona opuesta a la cara donde se encuentran dispuestos los elementos de excitación, donde los rebajes están dispuestos en las zonas de la corona del rotor con menor densidad de flujo magnético para minimizar el material magnético empleado y reducir el peso del generador, donde dependiendo de si existe o no continuidad en el flujo magnético a lo largo de todo el perímetro de la corona del rotor, los rebajes estarán enfrentados a los elementos de excitación o no respectivamente.Electric generator and wind turbine comprising said electric generator. # The present invention relates to an electric generator and the wind turbine comprising said generator, where the generator comprises a rotor where the radial section of its crown is variable along its perimeter due to which the rotor crown comprises recesses arranged on the face of the crown opposite the face where the excitation elements are arranged, where the recesses are arranged in the areas of the rotor crown with lower magnetic flux density to minimize the magnetic material used and reduce the weight of the generator, where depending on whether or not there is continuity in the magnetic flux along the entire perimeter of the rotor crown, the recesses will face the excitation elements or not respectively.
