Embodiment 1

[0017] Embodiment one, figure 2 It is a schematic diagram of the wind generator stator winding of the present invention. In the figure, 100 is the stator core, and 200 is the teeth on the stator core. The stator winding 1 of the present invention includes the first half winding 11 arranged on two adjacent teeth 200 The winding direction is opposite to that of the second half-winding 12 , and the end of the first half-winding 11 is connected to the head end of the second half-winding 12 . When winding, first, the first half winding 11 is wound on the linear bar mold, then the second half winding 11 is reversely wound, and the second half winding 12 is turned over to form a connected, reversely wound When installing the stator winding 1 composed of two half-windings, the two connected half-windings 11 and 12 are inserted into the adjacent stator teeth 200 at one time, thereby reducing the number of coil terminals and embedding wires. The number of times, improve the installati...

Embodiment 2

[0018] Embodiment two, see image 3 , the figure shows a quarter of the stator winding of the wind generator of the present invention, the stator core 100 has 48 teeth 200 (12 teeth are shown in the figure), and the stator core 100 is provided with 24 windings 1 ( 6 windings 1) are shown in the figure, and each winding 1 includes two one-time windings formed on two adjacent teeth 200 and connected as a whole, two half-windings: the first half-winding 11 and the The second half-winding 12 has the same winding direction, and the end of the first winding 11 is connected to the end of the second winding 12 . When winding, see Figure 4 , the figure shows the winding method of this embodiment, 300 in the figure is a linear rod mold, its two ends have the same shape and diameter, and there is a transition section 301 in the middle, first the first winding 11 is placed on the linear rod mold Winding is carried out at one end, and after completion, the wire is crossed over the trans...

Abstract

The invention discloses a wind driven generator stator winding which is a centralized winding and is characterized by comprising two semi windings which are wound once and arranged in adjacent stator tooth slots, wherein one ends of the two semi windings are connected with each other. The wind driven generator stator winding can be used for solving the problems of complex forming, connecting and line inserting of the centralized winding of a motor with a multi-tooth stator, and effectively improving the installation efficiency of a coil; and besides, welding points are less and the reliability is high.

Description

technical field [0001] The invention relates to a winding, in particular to a stator winding of a wind power generator and a winding method thereof. Background technique [0002] The existing stator windings of motors either use distributed windings or centralized windings. see figure 1 , for concentrated windings, in order to facilitate multiple series-parallel connections between windings, generally a wound-shaped concentrated winding is assembled to a tooth slot of the stator core, and then each concentrated winding is connected to obtain multiple windings. phase stator winding. For the stator of a large-scale wind turbine with a large number of teeth, if a concentrated winding is used, the assembly of the winding and the wiring after the embedding are obviously very complicated. Therefore, a stator winding that reduces the workload of the embedding and reduces the wiring become the goal pursued by those skilled in the art. Contents of the invention [0003] The pur...
