Rotor arrangement for a generator

1. A rotor arrangement for a generator, the rotor arrangement comprising:

a rotor including a plurality of circumferentially adjacently disposed magnetic elements; and

an axially extending spacer element disposed between at least two circumferentially adjacently disposed magnetic elements;

wherein the axially extending spacer element includes a plane base area attached to the rotor and includes a freely exposed inclination area which is inclined relative to the base area, wherein the axially extending spacer element further includes two inclination areas which are inclined relative to the base area; and

wherein the two inclination areas are inclined in an axial direction in such a manner that they build a tip portion at the axial centre of the spacer element.

2. The rotor arrangement according to claim 1 ,

wherein the two inclination areas are oppositely inclined relative to the base area.

3. The rotor arrangement according to claim 2 ,

wherein the two inclination areas are inclined with an acute angle relative to the base area.

4. The rotor arrangement according to claim 1 ,

wherein the axially extending spacer element is built of a plurality separate spacer element segments adapted to build the spacer element when assembled.

5. The rotor arrangement according to claim 4 ,

wherein the axially extending spacer element is built of two, particularly cross-sectionally, symmetrical spacer element segments, with the spacer element segments having a cross-sectionally wedge-like shape.

6. The rotor arrangement according to claim 1 ,

wherein an axially extending spacer element is disposed between all circumferentially adjacently disposed magnetic elements.

7. A wind turbine generator, comprising:

a stator; and

a rotor arrangement according to claim 1 .
