Problems solved by technology

[0007] Although modular generators may be advantageous for transport and maintenance or repair operations, the prior art solutions described above have disadvantages: In order to ensure that the generator has sufficient rigidity to withstand the operating conditions, the generator structure is too large
This undesirably leads to higher cost, but not better performance

Embodiment Construction

[0032] The drawings show different embodiments of rotor assemblies suitable for direct synchronous wind turbine generators. The rotor assembly is indicated as a whole by the reference numeral 10 throughout the drawings. In the respective drawings, the same reference numerals denote the same parts.

[0033] Such as Figure 7 with Figure 8 As shown, the rotor assembly 10 can be rotated relative to the stator assembly 300 via a suitable bearing 310.

[0034] As a non-limiting example in Figure 1-5 The embodiment of the rotor assembly 10 shown in includes six rotor segments 110. According to requirements, other embodiments of the rotor assembly 10 may also have other different numbers of rotor segments 110. E.g, Image 6 The illustrated embodiment of the rotor assembly 10 includes four rotor segments 110.

[0035] Such as Figure 1-6 As shown, the rotor segment 110 forms a modular rotor structure 100. Dividing the rotor structure 100 of the rotor assembly 10 into rotor segments 110...

Abstract

The rotor assembly (10) comprises a plurality of rotor segments (110) forming a rotor structure (100) and a ) of the central structure (200). A wind turbine generator comprising a stator assembly (300) and said rotor assembly (10) and a wind turbine comprising the generator are also provided.

Description

[0001] This application claims priority for European patent application EP11382029 filed on January 27, 2012 and US provisional patent application No. 61 / 616,105 filed on March 27, 2012. Technical field [0002] The present invention designs a rotor assembly, a wind turbine generator including the rotor assembly, and a wind turbine including the generator. Background technique [0003] Direct drive wind turbines are known in which the gearbox is replaced by a multi-pole generator, which is usually placed between the generator and the main shaft of the wind turbine. This type of gearless wind turbine does not use any gearboxes because the wind rotor is directly connected to the rotor of the wind turbine. Therefore, a multi-pole generator is also called a direct drive generator. The direct drive generator may be, for example, a synchronous generator with a wind rotor or a synchronous generator with permanent magnets arranged in the rotor. [0004] One of the main disadvantages of di...
