Arrangement for a direct drive generator, direct drive generator, wind turbine and generator assembly procedure

摘要

Arrangement for a direct drive generator (2) for a wind turbine (1), the generator (2) comprising a stator (17) with several stator segments (28), each stator segment (28) having at least one element (33) of stator for the generation of electric power and the generator (2) comprising a rotor (16) that can pivot about a central axis (A) of the generator (2) and with respect to the stator (17) with several segments (20) of the rotor, each rotor segment (20) having at least one rotor element (25) for generating electrical energy, whereby said arrangement comprises at least one stator segment (28) and at least one segment (20) of the rotor, characterized in that the at least one stator segment (28) and the at least one rotor segment (20) are configured such that the at least one rotor segment (20) rests at least temporarily, is say, during transport, assembly and disassembly, on the at least one sec Stator ment (28) after moving towards at least one stator segment (28) by constructing a unit of stator / rotor segments, whereby an air gap (34) remains between the at least one element (33) of stator and the at least one rotor element (25), in which the at least one stator segment (28) comprises at least a first support projection (60, 61) and in which the at least one segment ( 20) The rotor comprises at least a second support projection (57, 58), in which the first support projection (60, 61) of the at least one stator segment (28) and the second projection (57, 58) Supporting the at least one rotor segment (20) are configured to support each other at least temporarily.
