Abstract
A method of attaching a magnet to a rotor or a stator of an electrical machine is provided. The method includes arranging a magnet along a surface of the rotor or stator; arranging a pair of retainers, one on each side of the magnet; enclosing the rotor or stator, magnet and retainers in a vacuum bag; and performing vacuum evacuation to consolidate the magnet to the retainers by means of adhesive. A magnet mounting arrangement for a rotor or a stator of an electrical machine and a wind turbine with a generator including a rotor and a stator and such a magnet mounting arrangement are also provided.

A method of attaching a magnet to a rotor or a stator of an electrical machine, comprising:
- arranging a magnet along a surface of the rotor or stator;
- arranging a pair of retainers one on each side of the magnet;
- enclosing the rotor or stator, magnet and retainers in a vacuum bag;
- and
- performing vacuum evacuation to consolidate the magnet to the retainers by means of an adhesive,
- wherein a retainer is shaped to essentially cover a side face and at least part of the upper face of the magnet.
A magnet mounting arrangement for a rotor or a stator of an electrical machine, comprising:
- a magnet arranged along a surface of the rotor or stator;
- a pair of retainers arranged one on each side of the magnet;
- and
- an adhesive bonding the pair of retainers to the magnet and the magnet to the rotor or stator,
- wherein a retainer is shaped to essentially cover a side face and at least part of the upper face of the magnet.
