Abstract

A generator, particularly for a wind turbine, having a rotor and a stator is provided. The rotor includes at least one disc-like shaped rotor end plate supporting the rotor and the stator includes at least one disc-like shaped stator end plate supporting the stator, wherein the at least one rotor end plate and/or the at least one stator end plate at least partially extends tilted relative to the center axis of the generator.

First claim

We claim:

1. A generator, comprising:
a rotor comprising at least two disc-like shaped rotor end plates supporting the rotor, wherein two of the at least two rotor end plates are axially adjacently disposed and each are at least partially extending tilted relative to a centre axis of the generator, whereby the rotor end plates are disposed at one axial face side of the rotor, wherein each rotor end plate comprises a radially outer end; and
a stator comprising at least one disc-like shaped stator end plate supporting the stator, wherein each stator end plate comprises a radially outer end,
wherein the at least two of the at least two rotor end plates axially adjacently disposed and at least one stator end plate at least partially extends tilted relative to the centre axis of the generator in an outward direction towards a drive end,
wherein all of the radially outer ends of the respective rotor end plates converge in a common point at the axial face side of the rotor.

2. The generator according to claim 1 , wherein one stator end plate is disposed at each axial face side of the stator, whereby respective stator end plates at least partially extend tilted relative to the centre axis of the generator only at one axial face side of the stator.

3. The generator according to claim 1 , wherein at least one stator end plate is disposed at each axial face side of the stator, whereby at least one of the respective stator end plates at least partially extend tilted relative to the centre axis of the generator at one axial face side of the stator.

4. The generator according to claim 1 , wherein at least one rotor end plate is disposed at each axial face side of the rotor, whereby respective rotor end plates at least partially extend tilted relative to the centre axis of the generator only at one axial face side of the rotor.

5. The generator according to claim 1 , wherein at least one rotor end plate is disposed at each axial face side of the rotor, whereby at least one rotor end plate at least partially extend tilted relative to the centre axis of the generator at one axial face side of the rotor.

6. The generator according to claim 1 , wherein a first tilting angle a 1 , a 2 of the respective rotor end plates and a second tilting angle 3 of the respective at least one stator end plate are different.

7. The generator according to claim 1 , wherein, if both the rotor end plate and the stator end plate at least partially extend tilted relative to the center axis of the generator, the respective rotor and at least one stator end plates are disposed at the same axial face side of the generator.

8. The generator according to claim 1 , wherein a first tilting angle of the respective rotor end plate and a second tilting angle of the respective stator end plate are different.

9. The generator according to claim 1 , wherein, if the stator end plate partially extends tilted relative to the centre axis of the generator, the respective stator end plate comprises a first section perpendicularly extending relative to the center axis of the generator and a second section extending tilted relative to the center axis of the generator.

10. The generator according to claim 1 , wherein a tilting angle of respective tilted sections of a rotor end plate and/or stator end plate lies in the range of 1-700 in anti-clockwise or clockwise direction emanating from a vertical axis.

11. The generator according to claim 1 , wherein at least one stator end plate comprises at least one aperture.

12. A wind turbine, comprising:
at least one generator according claim 1 ,
wherein a first face side of the generator is oriented towards a drive-end of the wind turbine and second face side of the generator is oriented towards a non-drive end of the wind turbine.
