Directly actuated wind-turbine generator (41) that comprises a tower (11), a support structure (13) mounted on the tower (11), a power train actuated directly by a wind rotor (15), supported by a main shaft (29) connected to the support structure (13) by at least one bearing, the rotor of the generator (45) being rigidly connected to the rotor hub (17) and the generator stator (43) being rigidly connected to the main shaft (29), the generator rotor (45) and the generator stator (43) being arranged so that there is a predetermined variable dimension for the clearance (44) between them that is appropriate for allowing for changes in the dimension of the clearance (44), which changes may arise from internal and external forces acting on the generator (41) and the rotor hub (17), such that it is possible to maintain an acceptable distribution of the dimension of the clearance (44) for the generator (41) to be able to function in any operational situation. |
