Problems solved by technology

[0004] One difficulty associated with the aforementioned prior art is that many bolts and nuts are required to hold and maintain the permanent magnet in the correct position and to withstand the magnetic attraction force acting on the magnet once it is magnetized, thus placing the permanent magnet (including its mounting plate) The process of assembling or mounting to the rotor base is very time consuming

Embodiment Construction

[0024] will now refer to figure 1 and figure 2 Embodiments of the present invention will be described.

[0025] figure 1 A wind turbine 1 is shown schematically. The wind turbine 1 comprises a tower 2 , a nacelle 3 and a hub 4 . The nacelle 3 is located above the tower 2 . The hub 4 comprises a plurality of wind turbine blades 5 . The hub 4 is mounted to the nacelle 3 . Furthermore, the hub 4 is pivotally mounted so that it can rotate about an axis of rotation 9 . The generator 6 is located in the nacelle 3 . The wind turbine 1 is a direct drive wind turbine.

[0026] figure 2 The components of the generator 6 according to the invention are shown schematically in a perspective view. The generator 6 comprises a magnet assembly 11 and a base element 12 . The magnet assembly 11 includes at least one magnet 13 and a mounting plate 14 . The magnet 13 is connected to a mounting plate 14 . For example, the permanent magnets 13 are glued to the mounting plate 14 . The ...

Abstract

A method for assembling part of a generator (6) is provided, wherein a magnet assembly (11) comprising at least one magnet (13) and a mounting plate (14) is fastened to a base element (12) by welding (15) the mounting plate (14) to the base element (12).

Description

technical field [0001] The invention relates to a method for assembling parts of a generator. The invention further relates to a generator and a wind turbine. Background technique [0002] Permanent magnet (PM) generator rotors for wind turbines are known in the prior art. Here, rods or segments of permanent magnet material are mounted to the surface of the generator rotor on some rotor base structure. The purpose of these magnets is to induce current in the generator stator coils through which the magnets pass as the generator rotor rotates. Most importantly, the magnets are adequately fixed to the rotor base structure since the distance between the magnets and the stator coils is typically only a few millimeters. [0003] A permanent magnet rotor arrangement is provided in EP 1 860 755 A2. The arrangement comprises a rotor with a radial outer edge. The circumferential array of magnet holders is secured to the outer rim of the rotor by at least one screw or bolt. Bolt...
