1. A drive train assembly for a wind turbine comprising:
a rotor hub;
a generator module, wherein the generator module comprises:
a generator stator;
a stationary frame supporting the generator stator;
a generator rotor;
a shaft supporting and removably connected to the generator rotor, wherein the rotor hub comprises a hub mounting flange defining the downwind end of the rotor hub, and the shaft comprises a shaft mounting flange defining the upwind end of the generator module;
a bearing assembly rotatably mounting the shaft on the stationary frame, the bearing assembly comprising a front bearing and a rear bearing, wherein an upwind end of the shaft mounting flange comprises an annular mounting plane for connecting to the hub mounting flange and a bearing seat for the front bearing; and
an upwind end of the generator module attached to a downwind end of the rotor hub.
