  1. 1. Direct Driven Generators for Vertical Axis Wind Turbines

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sandra Eriksson; Uppsala universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronous generator; wind power; vertical axis wind turbine; simulations; experiments; finite element method; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP Teknisk fysik;

    Abstract : Wind power is a renewable energy source that is increasingly used all over the world. Most wind turbines have a horizontal axis of rotation but a few have a vertical axis of rotation. The concept presented in this thesis is a straight-bladed vertical axis wind turbine with a direct driven cable-wound permanent magnet synchronous generator. READ MORE

  2. 2. On Design and Analysis of a Novel Transverse Flux Generator for Direct-driven Wind Application

    University dissertation from Stockholm : KTH

    Author : Dmitry Svechkarenko; KTH.; [2010]
    Keywords : Transverse flux machines; permanent magnet machines; finite element analysis; direct-driven generator; offshore wind turbine; renewable energy;

    Abstract : This thesis deals with the analysis of a permanent magnet synchronous generator suited for direct-drivenwind turbines inmegawatt class. The higher specific torque and power density of a transverse flux permanent magnet machine in comparison to conventional radial-flux machines make it a promising solution for direct-driven wind turbine generators.

  3. 3. On analytical modeling and design of a novel transverse flux generator for offshore wind turbines

    University dissertation from Stockholm : KTH

    Author : Dmitry Svechkarenko; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transverse flux machines; permanent magnet machines; direct-driven gen- erator; offshore wind turbine; renewable energy; global warming; TECHNOLOGY Electrical engineering; electronics and photonics Electrical engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektroteknik;

    Abstract : The object of this thesis is to develop a cost effective direct-driven wind generator suited for offshore wind turbines. As the generator price is a complicated function dependent on many parameters, the emphasis is mainly put on reduction of the weight of active materials, such as copper, laminated steel, permanent magnets, and electrical insulation.
