Problems solved by technology

Therefore, when constructing an electromagnetic system composed of such a magnetic wheel (that is, all the independent permanent magnets in the magnetic wheel are arranged in a multi-row ring shape), especially if each row of magnets needs to be accurately arranged, it takes a relatively high cost. manufacturing cost

Embodiment Construction

[0044] Generally, each kind of wind power generation equipment or wind power generation equipment should include a rotor with a hub and a transmission disk, and a machine box for enclosing the generator. If the mechanical power generated by the rotor drive disc is to be converted into electrical power, it can be converted into electrical power through a multipolar generator (generally, a synchronous generator is preferred, that is, a generator driven according to the rotor speed, which is generally placed in the aforementioned machine box) )to realise. The multipolar generator mentioned here includes a stator with windings and a rotor. The rotor can surround the stator (ie, the outer rotor), or the stator can surround the rotor (ie, the inner rotor).

[0045] In the specification examples given below, an external rotor is described which constitutes an electromagnetic field system such as Figure 9 Shown in 1. The electromagnetic field system includes a plurality of magnetic...

Abstract

The invention relates to a method for installing an electromagnetic system (1) on a multipole generator for wind energy or wind power plants, the system comprising a magnetic ring (2, 2', 2a'- 2c', 2a-2j), the permanent magnets (4, 4') that align the magnetic poles according to a certain change rule are arranged on the outer or inner circumference of the magnetic ring, and it is necessary to adopt a simple and economical method in installation. Numerous and densely packed individual permanent magnets are attached to the inner or outer rotor of this multipole generator for wind energy or wind power plants. The method that this installation method can be realized is that the outer circumference or the inner circumference of the supporting device (5) has a receiving element (12), and a clip-shaped supporting element (6) is respectively installed inside or next to it, so that the A permanent magnet (4, 4') can be supported or fixed between every two adjacently installed supporting elements (6) on the supporting device (5).

Description

technical field [0001] The present invention relates to an excitation system in a multi-pole generating set (especially a wind generator or a wind energy generator), in which a magnetic ring with a supporting device is assembled, and the outer ring or inner ring of the device On the circle, many independent permanent magnets are regularly arranged, and the polarities of these permanent magnets are opposite to each other. Background technique [0002] Recently, new types of wind power generators or wind power generating sets have been successfully developed. In these wind power generation devices, the wind rotor-rotor-hub is used as a complete component of the generator set. The working principle of the generator is that the inner stator and the outer rotor work together. This type of generating set has been described in the patent "DE10239366A1". In order to construct the rotor located at the outer end in this type of generator, it is necessary to install numerous permanen...
