  3. 2. Development of the Winding Geometry for an Efficient Wave Power Generator

    Kandidat-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Thomas Wall; [2017]
    Nyckelord :;

    Sammanfattning : A method for twisting a stranded cable in orderto reduce losses due to circulating currents is investigated. Atheoretical model connecting the voltages over individual strandsto the magnetic flux through the cable is presented. A modelsimplifying the geometry of the cable is developed. LÄS MER
