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.
