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

    Författare :Dmitry Svechkarenko; Chandur Sadarangani; Waqas Arshad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transverse flux machines; permanent magnet machines; direct-driven gen- erator; offshore wind turbine; renewable energy; global warming; Electrical engineering; Elektroteknik;

    Sammanfattning : 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.

  3. 7. Integrated In-Wheel Motors for Low Power Traction Application

    Författare :Prakashraj Kasinathan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric golf cart; integral-slot; force density; flux-linkage; traction motors; forklift trucks; direct-drive; electric wheelchairs power wheelchairs; low speed machines; fractional-slot;

    Sammanfattning : This thesis is primarily concerned with the practical limits, imposed by magnetic saturation and thermal considerations, of the force density in low-speed permanent-magnet electric machines. The practical force density values obtainable in integral- and fractional-slot machines are determined. LÄS MER

  4. 8. Performance Evaluation and Life Cycle Cost Analysis of the Electrical Generation Unit of a Wave Energy Converter

    Författare :Pinar Tokat; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The main focus of this work is the performance and the economical assessment of a radial flux generator that is used in wave power applications. The wave energy converter (WEC) used in this work is a point absorber, that is considered to move only in heave. LÄS MER
