Electric generator and process for assembling a wind turbine equipped with said generator

摘要

The invention consists of a generator (1) having a rotor which comprises rotor (2) excitation element-carrying modules (4), for example magnets, radially movable in relation to the generator (1) shaft in such a manner, when in their retracted position, as to significantly ease generator (1) transport and assembly. The use of these movable magnet-carrying modules (4) is particularly useful in direct drive-type generators which do not require a multiplier. Another object of the invention is an assembly process which comprises a generator (1) equipped with said radially movable magnet-carrying modules (4).
