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

    Author : Dmitry Svechkarenko; Chandur Sadarangani; Zi-Qiang Zhu; KTH; []
    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.

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

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

  4. 4. Design of Direct-driven Permanent-magnet Generators for Wind Turbines

    Author : Anders Grauers; Chalmers University of Technology; []
    Keywords : optimization; direct drive; synchronous generator; wind turbine; design; low speed; permanent magnet; frequency converter;

    Abstract : This thesis presents an investigation of how a direct-driven wind turbine generator should be designed and how small and efficient such a generator will be. Advantages and disadvantages of various types of direct-driven wind turbine generators are discussed, and a radial-flux permanent-magnet generator connected to a forced-commutated rectifier is chosen for a detailed theoretical investigation.
