Abrégé

The invention relates to a stator (1) of a generator of a wind power station or wind energy plant comprising a liquid cooling system for the region of the stator sheet stacks (5). The stator (1) comprises a plurality of axial tubes (8) and/or axial borings (7) through which a liquid cooling medium can flow, said tubes or borings extending inside or outside of the stator sheet stacks (5) over the axially extending extension, in a longitudinal manner of the periphery thereof limited or formed by the stator sheet stacks (5). The aim of the invention is to provide a solution to improve the cooling of the sheet stacks of the stator. Said aim is achieved due to the fact that the axial tubes (8) and/or the axial borings (9) are components of a cooling fluid line (15), in particular, of a closed cooling circuit, said cooling fluid line (15) running through the region which is to be cooled in a meandering manner.

The aim of the invention is to allow an external or internal rotor of a wind turbine generator to be easily and favorably equipped with a plurality of closely arranged individual permanent magnets in a magnet system (1) of a multi-pole generator, especially for a wind turbine, said generator comprising a magnet ring (2, 2', 2a' - 2c', 2a - 2j) that includes a support (5), on the outer or inner circumference of which individual permanent magnets (4, 4') are arranged in a row, the direction of the polarity of said magnets (4, 4') being regularly reversed. Said aim is achieved by providing the surface of the outer or inner circumference of the support (5) with receiving elements (12), within or on each of which a clamp-type holding element (6) is disposed, wherein two holding elements (6) that are disposed at a distance from each other retain and/or fix an individual permanent magnet (4, 4') on and/or to the support (5) between the two holding elements (6).

The aim of the invention is to make it easier and thus faster to mount switchgear cubicles in rotating parts of a wind turbine, i.e. in a rotor of a wind turbine generator comprising a magnet wheel that rotates in or around a stator and is equipped with a magnet wheel housing (1, 9). Said aim is achieved by forming receiving surfaces and/or receiving spaces (8) within or on the magnet wheel housing (1, 9). On and/or inside said receiving surfaces and or receiving spaces (8), switchgear cubicles can be and/or are co-rotatingly arranged that contain electrical control and/or switching elements which include parts performing a switching movement to establish and/or interrupt an electrically conducting connection.

The aim of the invention is to allow an external or internal rotor of a wind turbine generator to be easily and favorably equipped with a plurality of closely arranged individual permanent magnets in a magnet system (1) of a multi-pole generator, especially for a wind turbine, said generator comprising a magnet ring (2, 2', 2a' - 2c', 2a - 2j) that includes a support, on the outer or inner circumference of which individual permanent magnets (4, 4) are arranged in a row, the direction of the polarity of said magnets (4, 4') being regularly reversed. Said aim is achieved by laterally joining several magnet rings (2, 2', 2a - 2j, 2a' - 2c') in an axial direction such that said magnet rings radially rest against each other and form a magnet wheel (10).

The aim of the invention is to provide a solution for a rotor of a generator of a wind generator or wind turbine comprising a pole wheel that has a pole wheel housing (1, 9) and that rotates in or around a stator that allows the simplified assembly of switchgear cabinets that are to be installed in rotating components of a wind turbine and that reduces the complexity of said assembly and the number and mass of the rotating components that are to be positioned on the tower of a wind turbine. To achieve this, the blades of the rotor in the wind generator or wind turbine and the switchgear cabinets that comprise the electric control and/or switching elements of the associated pitch system can be and/or are positioned on and/or in the pole wheel housing (1, 9) of the rotor.

Abrégé

The invention relates to a method for producing a magnetic system (1) of a multi-pole generator in a wind generator or wind turbine, comprising a pole wheel (13), said system having a connection between a pole wheel housing (11) and at least one magnetic ring (2) that has a plurality of individual permanent magnets (4, 4') arranged in a ring, or between said housing and at least one magnetic wheel (10) that has a magnetic ring (2) and a support (5) holding said ring, achieved by heating the pole wheel housing (11) to a temperature at which the internal diameter of an internal peripheral surface of the pole wheel housing (11) that forms a receiving surface (14) expands to a size that is greater than the external diameter of the magnetic ring (2) or the magnetic wheel (10) and by the positioning of the at least one magnetic ring (2) or magnetic wheel (10) in or on the receiving surface (14) and the shrinkage of the pole wheel housing (11) onto the at least one magnetic ring (2) or magnetic wheel (10) by cooling the pole wheel housing (11) to the ambient temperature. The aim of the invention is to provide a solution that results in a reliable and highly stable connection between a magnetic ring or a magnetic wheel and a pole wheel housing whilst at the same time allowing the assembly to be simplified and made more cost-effective. To achieve this, before the pole wheel housing (11) is heated and/or before the magnetic ring (2) or the magnetic wheel (10) is positioned and/or before the pole wheel housing (11) is cooled, the external peripheral surface of the at least one magnetic ring (2) or magnetic wheel (10) and/or the receiving surface (14) is provided with an adhesive (15) that forms a bonded connection between the pole wheel housing (11) and the at least one magnetic ring (2) or magnetic wheel (10) when the pole wheel housing (11) shrinks.
