| 1. A generator for a wind turbine having a tower, a nacelle, and a hub, the generator comprising:
a stator supporting frame having a stator supporting portion, a radially extending portion and a rotor frame supporting portion,
wherein the stator supporting frame is stationarily mountable within the nacelle;
a rotor frame rotatably supported on the rotor frame supporting portion of the stator supporting frame, wherein the rotor
frame is connectable to the hub;
a gear driven by the rotor frame, the gear comprising:
a ring gear stationarily mounted to the stator supporting frame;
a carrier gear assembly rotatably mounted to the rotor frame and meshing with the ring gear; and
a ring-shaped sun gear meshing with the carrier gear assembly; and
a rotor generator ring support frame rotatably supported and radially positioned outward of the rotor frame supporting portion
of the stator supporting frame,
wherein the sun gear is fixedly and directly mounted to the rotor generator ring support frame.
