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

    Författare :Sandra Eriksson; Hans Bernhoff; Mats Leijon; Jörgen Blennow; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronous generator; wind power; vertical axis wind turbine; simulations; experiments; finite element method; Engineering physics; Teknisk fysik;

    Sammanfattning : 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. LÄS MER
