Abstract:
1. A wind turbine generator, comprising: a generator including a stator and a stator casing accommodating a generator rotor and the stator; a main shaft having one end coupled to a wind turbine rotor and the other end coupled to the generator rotor; a first bearing rotatably supporting said main shaft; a second bearing provided on said main shaft to support said stator casing such that said main shaft and said stator casing are rotatable with respect to each other; a base to which said first bearing is attached; and a torque support including a coupling member which couples said base portion and a front plate of said stator casing, wherein a load center of a force acting between said coupling member and said front plate in a case that torque acts on said stator casing in a circumferential direction of said main shaft is positioned in a range between front and back surfaces of said front plate.
