Abstract

A magnet assembly is disclosed. The magnet assembly includes a base element and a magnet attached to a first surface of the base element. A second surface of the base element opposite to the first surface of the base element includes a contour, which is adapted to engage with a complementary contour of a support structure of a rotor arrangement. It is further described a method for engaging a magnet assembly to a support structure of a rotor arrangement, a rotor arrangement for an electromechanical transducer, an electromechanical transducer and a wind turbine.

First claim

The invention claimed is:

1. A magnet assembly, comprising:
a base element that includes a first and second surface, the first surface on an opposite side of the base element from the second surface, the second surface includes a contour adapted to engage with a complementary contour of a support structure of a rotor arrangement;
a magnet attached to the first surface of the base element; and
a protective cover encapsulating the magnet, the protective cover consisting of a non-metallic material.

2. The magnet assembly as set forth in claim 1 , wherein the contour and/or the complementary contour is formed in a dove tail manner.

3. The magnet assembly as set forth in claim 1 , wherein the support structure of the rotor arrangement comprises a protrusion and wherein the base element comprises a recess for engaging with the protrusion of the support structure of the rotor arrangement.

4. The magnet assembly as set forth in claim 1 , wherein the base element comprises a protrusion and wherein the support structure of the rotor arrangement comprises a recess for engaging with the protrusion of the base element.

5. The magnet assembly as set forth in claim 1 , wherein the magnet is attached to the base element by a gluing material.

6. The magnet assembly as set forth in claim 1 , the protective cover is fixed to the base element.

7. A rotor arrangement for an electromechanical transducer, the rotor arrangement comprising
a support structure; and
a magnet assembly as set forth in claim 1 .

8. An electromechanical transducer, comprising:
a stator assembly; and
a rotor arrangement as set forth in claim 7 .

9. The electromechanical transducer as set forth in claim 7 , wherein the electromechanical transducer is a generator.

10. A wind turbine, comprising:
a tower;
a rotor, which is arranged at a top portion of the tower and which comprises a blade; and
an electromechanical transducer, comprising:
a stator assembly; and
a rotor arrangement as set forth in claim 7 .
