Publication number: 20120091837Abstract: 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.Type: ApplicationFiled: November 19, 2009Publication date: April 19, 2012Applicant: Avantis Ltd.Inventors: Klaus Bodenstein, Detlef Lange, Dieter Rupprich

Publication number: 20120091724Abstract: The invention relates to a generator of a wind power station or a wind turbine comprising a stator (1) and a rotor (2) in addition to a disc brake. The aim of the invention is to provide a solution making it possible to provide a generator and a disc brake having a compact structure. Said aim is achieved in such a manner that the disc brake is integrated into the generator, said disc brake comprising a brake disc (6) which is embodied on the inner side on the outer rotor (2) and brake blocks (7) which are embodied on the inner side on the stator (1).Type: ApplicationFiled: November 17, 2009Publication date: April 19, 2012Applicant: Avantis Ltd.Inventors: Klaus Bodenstein, Detlef Lange, Dieter Rupprich

Publication number: 20120049519Abstract: In the case of a rotor of a generator of a wind power installation or of a wind energy installation having a pole wheel which rotates in a stator or around a stator and has a pole wheel housing (1, 9), the aim is to create a solution which provides a simplified assembly capability for switchgear cabinets to be installed in rotating components of a wind power installation, with the capability to reduce the assembly effort and to reduce the number and the mass of the rotating components to be arranged on the equipment tower of a wind power installation. This is achieved in that the blades of the wind rotor of the wind power installation or wind energy installation and the switchgear cabinets, which have the electrical control and/or switching elements of the associated blade control system (pitch system) can be arranged and/or are arranged on and/or at the pole wheel housing (1, 9) of the rotor.Type: ApplicationFiled: November 19, 2009Publication date: March 1, 2012Applicant: Avantis Ltd.Inventors: Detlef Lange, Dieter Rupprich, Klaus Bodenstein

Publication number: 20120049684Abstract: In the case of a magnet system (1) of a multipole generator, in particular for a wind energy installation or wind power installation, comprising a magnet ring (2, 2?, 2a?-2c?, 2a-2j) having a support (5) on whose external circumference or internal circumference individual permanent magnets (4, 4?) are arranged in one or more rows with a regularly changing polarity alignment, the aim is to provide an assembly capability which makes it possible to equip an external rotor or an internal rotor for a generator of a wind power installation with a multiplicity of individual permanent magnets, which are arranged close to one another, in a manner which is simple and advantageous for assembly. This is achieved in that a plurality of magnet rings (2, 2?, 2a-2j, 2a?-2c?) are joined together at the side, in the axial direction, coaxially and resting on one another, to form a magnet wheel (10).Type: ApplicationFiled: November 19, 2009Publication date: March 1, 2012Applicant: AVANTIS LTD.Inventors: Klaus Bodenstein, Detlef Lange, Dieter Rupprich

Publication number: 20120049518Abstract: In the case of a rotor of a generator of a wind power installation or of a wind energy installation having a pole wheel which rotates in a stator or around a stator and has a pole wheel housing (1, 9), the aim is to create a solution which provides a simplified assembly capability for switchgear cabinets to be installed in rotating components of a wind power installation, with the capability to reduce the assembly effort. This is achieved in that retaining surfaces and/or retaining areas (8) are formed in or at the pole wheel housing (1, 9) and switchgear cabinets having electrical control and/or switching elements, which are arranged therein and have components which carry out a switching movement to switch and/or break an electrically conductive connection, can be arranged and/or are arranged such that they also rotate thereon and/or therein.Type: ApplicationFiled: November 19, 2009Publication date: March 1, 2012Applicant: Avantis LtdInventors: Klaus Bodenstein, Detlef Lange, Dieter Rupprich
