This paper describes the design process of a 10 MW permanent magnet synchronous generator for wind turbine application. In order to achieve a high power output combined with a relatively low weight, a ring structure is chosen for the generator, with the generator’s length being less than 1/30 of the diameter. To reduce weight further, a tooth-wound coil winding is chosen for the generator. The electromagnetic layout, the power electronics concept, and the structural design of this new ring generator are presented in this paper, as well as the resulting generator design
This paper presents the design and control structure of a synchronous generator in ring form. The analysed generator is designed in order to test the control structure of a light-weight 10 MW generator for wind turbines. A segmented stator structure with distributed control allows control of the current of single stator segments which facilitates damping of axial displacement due to varying wind speeds by controlling axial forces. The layout process of the generator, its distributed control and the damping control are presented in this paper
