Abstract

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.
