摘要
A direct-drive wind turbine generator is provided with: a main shaft having one end connected to a rotor head of a wind turbine rotor; a generator having a stator, a stator casing for supporting the stator, and a rotor connected to the other end of the main shaft; first and second bearings positioned between the rotor head and the generator to rotatably support the main shaft; and a torque support for supporting the stator casing. The second bearing is positioned closer to the generator than the first bearing. The first bearing is a bearing with an aligning capability, and the second bearing is a bearing with no aligning capability.
