Direct-drive permanent magnet (PM) synchronous machines for wind turbines are large, heavy and thus expensive to build, transport and install. The structure that is required to maintain the airgap clearance is often heavier than the electromagnetically active material. It is show ...
Wave energy is currently an untapped resource, but has the potential to make a significant contribution to the energy mix. In order to use conventional electrical generators mechanical interfaces are used, such as hydraulic systems and air-turbines, With the electrical generator ...
The objectives of this paper are to investigate the feasibility of a 10 MW generator for a direct-drive wind turbine and to compare the generator systems for pitch control and for active speed stall control. The idea behind the active speed stall control concept is to make a roto ...
The archimedes wave swing (AWS) is a system that converts ocean wave energy into electric energy. The goal of the research described in this paper is to identify the most suitable generator type for this application. Of the conventional generator types, the three-phase permanent- ...
