DIRECT-DRIVE GENERATOR/MOTOR FOR A WINDMILL/HYDROPOWER PLANT/VESSEL WHERE THE GENERATOR/MOTOR IS CONFIGURED AS A HOLLOW PROFILE AND A METHOD TO ASSEMBLE SUCH A WINDMILL/HYDROPOWERPLANT

摘要

A turbine rotor for a wind power plant or a hydropower plant with a direct-drive generator for converting the energy in flowing wind or water intoelectrical energy wherein the wind or hydropower plant comprises a turbinerotor and a stator and wherein the turbine rotor further comprises a ring-shaped hub (6) having an axis of rotation that coincides with the centre axisof the stator and wherein the turbine rotor comprises at least one rotorblade, which rotor blade is arranged on the ring- shaped hub. The turbinerotor is also intended to be used as a propeller for a craft.
