3. 2. Consequences of Magnetic Properties in Stainless Steel for a High-efficiency Wave Power Generator

   Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Mohamed Sheikh Abdi; Yosef Gebresilassie; [2018]
   Nyckelord :stainless steel; wave power; permeability;

   Sammanfattning : A new kind of wave power generator is being developed at KTH Royal Institute of Technology which potentially can reach an efficiency of 98 %. However, this generator’s small air gap sets strict requirements on the stiffness of the structure to withstand the large magnetic forces. The structure, therefore, need to be both stiff and non-magnetic. LÄS MER
