11. Design, Modelling and Control of Electrical Machines - With Applications to Iron-powder Machines and Acoustic Noise
Abstract : This thesis consists of two parts, the first dealing with the design of iron-powder synchronous machines, and the second with the analysis and prediction of the acoustic noise in electrical machines. In Part I, a 1.6 kW electrically magnetized claw-pole machine with magnetically conducting end-plates has been analyzed and a prototype tested. READ MORE

15. On analytical modeling and design of a novel transverse flux generator for offshore wind turbines
Abstract : 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.
