  • Publication number: 20160079834
    Abstract: A cogless electric generator consisting of a compressed nearly all copper air core stator placed within a surrounding rotor containing a plurality of permanent magnets is described which is particularly suitable for direct-drive integration with small-wind turbines. Such turbines become capable of generating electric energy at very low wind speeds. A particular focus is in reducing maintenance and operational costs of such a device by eliminating magnetic attraction of internal components typical of such generators and by reducing friction on bearings through the use of magnetic levitation. Techniques are employed to reduce eddy currents to increase the efficiency of the generator. Air scoops and air flow considerations combined with convective elements intimately in contact with and extending through the stator, allow heat directly from the stator to be dissipated externally.
