Claim Text:
1. A generator for a wind turbine, comprising: a stator; a rotor comprising a rotor housing surrounding the stator; and a main bearing adapted to support the rotor housing to be rotatable about an axis of rotation, wherein the stator comprises a plurality of cylindrical elements extending in parallel with the axis of rotation, and wherein the rotor comprises a front element having a plurality of holes at positions aligned with the cylindrical elements, and wherein the rotor is fixable to the stator by inserting fastening members through the cylindrical elements and the holes aligned with the cylindrical elements; further comprising a rotor brake and a rotor lock, wherein the rotor brake comprises a brake disc and the rotor lock comprises a lock bracket, wherein the rotor brake and the lock bracket are fixed relative to the stator, wherein the lock bracket comprises a recess for receiving the brake disc and is adapted to engage with the brake disc to lock the rotor at a predetermined angular position, wherein a further plurality of cylindrical elements extending in parallel with the axis of rotation is arranged at the lock bracket, wherein the brake disc comprises a further plurality of holes aligned with the further cylindrical elements, and wherein the rotor is further fixed to the stator by inserting further fastening members through the further cylindrical elements the further holes aligned with the further cylindrical elements.
