Abstract

The invention provides a synchronous-generator stator, comprising a stator ring, a stator core, a circumferential gap between the stator ring and the stator core, and a plurality of decoupling units in the gap, wherein the decoupling unit has a first plate, which is matched to a contour of the stator core, and has a second plate, which is matched to the contour of the stator ring, wherein a mat, having a cavity and an inlet valve, is provided between the first and the second plate.

First claim

The invention claimed is:

1. A synchronous-generator stator, comprising:
a stator ring;
a stator core;
a circumferential gap between the stator ring and the stator core; and
a plurality of decoupling units in the gap, wherein each of the plurality of decoupling units has:
a first plate having a contour that is matched to a contour of the stator core;
a second plate having a contour that is matched to a contour of the stator ring; and
a mat having a cavity and an inlet valve, the mat being located between the first and the second plate.

2. The synchronous-generator stator according to claim 1 , wherein each of the mats is a vulcanized rubber pressure mat.

3. A synchronous generator, comprising:
a synchronous-generator stator, having:
a stator ring;
a stator core;
a circumferential gap between the stator ring and the stator core; and
a plurality of decoupling units in the gap, wherein the plurality of decoupling units have:
a first plate having a contour corresponding to a contour of the stator core;
a second plate having a contour corresponding to a contour of the stator ring; and
a mat provided between the first and the second plate, the mat having a cavity and an inlet valve.

4. A wind turbine comprising a synchronous generator according to claim 3 .

5. A method for mounting a synchronous-generator stator that has a stator ring and a stator core, the method comprising the steps:
inserting the stator core in the stator ring such that there is a circumferential gap between the stator ring and the stator core;
inserting a plurality of decoupling units in the gap, the plurality of decoupling units having a first plate having a contour corresponding to a contour of the stator core and has a second plate having a contour corresponding to a contour of the stator ring, each of the plurality of decoupling units including a mat between the first and the second plates, the mat having a cavity and an inlet valve; and
introducing a pressure medium through the inlet valves of the plurality of decoupling units and filling the cavity of the mats between the first and second plates.

6. The synchronous generator according to claim 3 , further comprising a pressure medium in the cavity of the mat.

7. The synchronous generator according to claim 3 , wherein the mat is a vulcanized rubber pressure mat.
