Magnet ring of a multi-pole generator for a wind turbine

Abstract

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).
