Abstract:
Disclosed is a direct drive generator for a wind turbine, the generator including a rotor, a stator configured to remain stationary relative to the rotor, and at least one bearing connected to the stator. The rotor includes at least one rotor part extending circumferentially about an axis of rotation and a plurality of active materials arranged on a side of the at least one rotor part. The stator includes at least one stator part extending circumferentially about the axis of rotation and positioned adjacent to the at least one rotor part, and at least one winding arrangement supported by the at least one stator part and facing the plurality of active materials. The bearing is flexibly connected to the at least one stator part, wherein the bearing abuts the rotor part to help maintain a gap between the at least one winding arrangement and the active materials.
