Design of NewGen Direct-Drive Generator for Demonstration in a 3 , 5 MW Wind Turbine

  title={Design of NewGen Direct-Drive Generator for Demonstration in a 3 , 5 MW Wind Turbine},
  author={Staffan Engstr{\"o}m and S. R. Lindgren},
The NewGen is a new type of direct drive generator for wind turbines, based on the idea to put the generator bearings adjacent to the air-gap of a large diameter generator. In this way the stiffness requirements of the rotor and the stator are drastically reduced, which leads to large mass savings in the mechanical structure and enables a further diameter increase, which then results in mass reductions also in electrically active parts. The design is based on excitation by use of rare-earth…
