Linear Ferrite Generator Prototype for Wave Power
Abstract: A linear, direct drive, scale model prototype generator has been designed at KTH Royal Institute of technology in Sweden. The prototype is based on a scaled down electromagnetic optimization made by researcher Anders Hagnestål. The aim of the project is to verify the calculations experimentally and by using ferrite magnets, there is an opportunity to develop a competitively priced and environmentally friendly generator for wave power plants. Based on the electromagnetic optimization a mechanical design has been developed using computer aided design (CAD). Structural calculations have been made to ensure that the design withstands the large magnetic forces involved. Furthermore, different techniques and challenges appearing in the build of the prototype have been evaluated and explained. A description of the advantages of the design and the basic electromagnetic design is also included. The build is underway and is expected to be finished during 2018.
