Patent number: 8035246Abstract: A direct-drive power train of a wind power plant is protected from over-torque by a torque limiting device. The power train includes a turbine rotor including a hub and blades supported on the hub, and a generator including a stator and a generator rotor rotatably disposed within the stator. The generator rotor includes a generator rotor body, a rotor shaft, and the torque limiting device connects the generator rotor body to the rotor shaft. The torque limiting device is configured to support the generator rotor body within the stator and allow coaxial rotation of the rotor body relative to the stator. The hub and the generator rotor are connected by the rotor shaft, and the rotor shaft rotates at the same frequency as the hub.Type: GrantFiled: January 7, 2010Date of Patent: October 11, 2011Assignee: American Superconductor CorporationInventor: Peter M.
