Title
(EN) SHROUDED WIND TURBINE WITH RIM GENERATOR AND HALBACH ARRAY
(FR) EOLIENNE CARÉNÉE À ROTOR PÉRIPHÉRIQUE ET ENSEMBLE DE HALBACH
Abstract
(EN)
A wind turbine comprises a turbine shroud and optionally an ejector shroud. The wind turbine encloses a permanent magnet ring generator. A static ring of phase windings is located in the turbine shroud, and wind airflow causes a rotor having permanent magnets thereon to rotate, creating an electric current in the static ring. The permanent magnets are arranged to form a Halbach cylinder with the magnetic field being exterior to the rotor.
(FR)
L'invention concerne une éolienne comprenant un carénage de turbine et en option un carénage d'éjecteur. L'éolienne entoure un générateur annulaire magnétique permanent. Un anneau statique d'enroulements de phase est situé dans le carénage de turbine, et un courant d'air fait tourner un rotor sur lequel se trouvent des aimants permanents, en créant un courant électrique dans l'anneau statique. Les aimants permanents sont disposés de manière à former un cylindre de Halbach avec le champ magnétique extérieur au rotor.
