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.

Description

[0001] This application claims priority to US Provisional Patent Application No. 61 / 222,142, filed July 1, 2009. This application is also a continuation-in-part of U.S. Patent Application No. 12 / 054050, filed March 24, 2008, which claims priority to U.S. Provisional Patent Application No. 60 / 919,588, filed March 23, 2007 right. This application is also a continuation-in-part of U.S. Patent Application No. 12 / 629714, filed December 2, 2009, which claims priority to U.S. Provisional Patent Application No. 61 / 119078, filed December 2, 2008 right. The entire disclosures of these applications are hereby incorporated by reference in their entirety. technical field [0002] The invention relates to rim generators for shrouded wind turbines. In particular, ring generator variants based on rotor / stator assemblies are used as permanent magnet generators. The magnets contained in the ring generator are arranged in a Halbach array in order to enhance the power generation of the shroud...
