Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] The low-speed multi-pole synchronous generator includes a housing 1 on which a stator 2 with a stator coil 3 is fixed, and the stator coil 3 is wound on an n-shaped magnetic conductor 4 .

[0025] On the shaft of the low-speed multipole synchronous generator (shaft not shown in the figure) is fixed a rotor 5 made in the form of a disc with inserts made of permanent magnets 6 . The permanent magnets 6 are installed in the rotor 5 alternately with respect to the direction of magnetization. At this time, the permanent magnets 6 are installed on the rotor 5 in such a way that the magnetizers 4 of the stator coils 3 are displaced circumferentially, that is, every 10th permanent magnet 6 or the magnetizers 4 of the stator coils 3 are arranged opposite to each other, so that Whichever is the most shall prevail. This ratio ensures a reduction in movement for...

Abstract

The invention relates to a low-speed multipole synchronous generator comprising a stator in the form of n-shaped segments with a winding formed from stator coils provided with one coil per pole and combined into different coil groups, as well as a rotor with permanent magnets arranged on the rim along the rotor. The rotor is in the form of a disk with inserts consisting of permanent magnets fixed alternately relative to the direction of magnetization, wherein the permanent magnets on the rotor are mounted with a circumferential shift relative to the yokes of the stator coils in such a way that every 10th magnet or yoke of the stator coil is arranged opposite one another depending on which poles there are more of.; The proposed synchronous generator has a significantly lower mass in comparison with the prior-art technical solution.

Description

technical field [0001] The invention relates to electrical engineering, in particular to the design of a low-speed multi-pole synchronous generator, and in particular can be widely used in the design of wind turbines. Background technique [0002] Magnetoelectric generators comprising a stator and a segmented rotor are known (cf. А.с.СССР No. 861716). The stator has a three-phase winding made of coils arranged one coil per pole and combined into different coil groups. The rotor has permanent magnets which are arranged on a yoke along the rotor axis. [0003] However, such an engine has a large mass and size, is complicated to manufacture, and has a current frequency of 50 Hz, which can only be achieved when the rotor rotates at a high speed, which is not allowed for the use of the generator in the design of a wind turbine. [0004] The closest to the present invention is a low-speed multi-pole synchronous generator (see Ukrainian Invention Patent Publication No.42513, publ...
