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

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 into electrical energy wherein the wind or hydropower plant comprises a turbine rotor and a stator and wherein the turbine rotor further comprises a ring-shaped hub (6) having an axis of rotation that coincides with the center axis of the stator and wherein the turbine rotor comprises at least one rotor blade, which rotor blade is arranged on the ring-shaped hub. The turbine rotor is also intended to be used as a propeller for a craft.
