Embodiment Construction

[0080] figure 1 A portion of the outer support structure of the generator is shown.

[0081] figure 1 Module 1 showing the support structure of an external rotor generator.

[0082] The modules 1 are equipped at the upper and lower ends with mechanisms for connecting the modules 1 to adjacent modules. These mechanisms include holes, which can be used, for example, for bolts.

[0083] The inner side 2 of the module 1 comprises fixing means 4 to support the permanent magnets in the generator. The permanent magnets can be slid into the fixing mechanism 4 from the upper side or the lower side of the module 1 .

[0084] Module 1 comprises insulating stacked laminates 6 . The plate 6 is formed in such a way that it includes the fixing means 4 for the permanent magnets.

Abstract

The invention relates to an improved outer structure of a generator. A generator comprises a rotor and a stator, whereby the generator is a radial flux electrical machine. An outer part of the generator is the stator or the rotor, whereby the outer part of the generator comprises a support structure. The support structure is modular and the modules 1 are arranged in rows 9, 10, 11. The modules 1 are arranged in a staggered manner, so that a module 1 in a first row 9 of modules 1 is connected to two modules 1 of a second row 10 abutting on the first row 9.

Description

technical field [0001] The invention relates to an improved outer structure of a generator. Background technique [0002] Generators convert mechanical energy into electrical energy. [0003] The generator is usually used as a direct drive generator. In this case, rotational energy is fed directly to the generator, said rotation not being transmitted by gears. [0004] This is often the case in wind power plants or in hydropower plants, where the rotor of the turbine is directly coupled to the generator. These direct drive generators turn more slowly than generators with gear transmissions. [0005] Depending on the power of the generators and according to the torque, these generators have a diameter greater than 4 meters and a length greater than 2 meters. [0006] The size of the generator often causes problems in the transportation of the generator. This may be due to the size and / or weight of the generator. [0007] The generator is constructed as an electric machi...
