Problems solved by technology

[0002] When the existing multi-layer winding is wound, the wire transposition operation is mostly performed on the straight side of the winding. The straight line side for the transposition operation is not neatly arranged, and the cross-sectional width of the straight side for the transposition operation is likely to exceed the tolerance. When the multi-layer winding is embedded in the iron core, the winding is not easy to be embedded in the iron core or the insulating paint surface of the wire is damaged after being embedded in the iron core

Embodiment Construction

[0027] The invention discloses a winding method of a multi-layer winding, which reduces the difficulty of embedding the multi-layer winding into an iron core and simultaneously avoids the damage of the iron core to the insulating paint surface of the multi-layer winding. The invention also discloses a multilayer winding.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] see Figure 1-Figure 4 , figure 1 Schematic diagram of the structure of the wire arrangement on the first arc-shaped...

Abstract

The invention discloses a multilayer winding and a winding method thereof. In the process that the multilayer winding is embedded into an iron core, only the straight line edge is embedded into the iron core, the first arc edge and the second arc edge are not embedded into the iron core, in the scheme, a wire changes the position on the first arc edge, the first arc edge with wire turns not arranged neatly is not embedded into the iron core, and after winding of the multilayer winding is completed, it can be guaranteed that the structures and sizes of the two straight line structures of the winding are consistent, wire turn arrangement is neat, the size meets the tolerance requirement, the difficulty of the winding embedded into the iron core is lowered, damage caused by the iron core to insulating paintwork can be effectively avoided, and insulating reliability of use of the multilayer winding is guaranteed.

Description

technical field [0001] The invention relates to the technical field of traction motor manufacturing, in particular to a multilayer winding and a winding method thereof. Background technique [0002] When the existing multi-layer winding is wound, the wire transposition operation is mostly performed on the straight side of the winding. The straight line side for the transposition operation is not neatly arranged, and the cross-sectional width of the straight side for the transposition operation is likely to exceed the tolerance. When the multi-layer winding is embedded in the iron core, the winding is not easy to be embedded in the iron core or the insulating paint surface of the wire after the iron core is embedded is damaged. [0003] Therefore, how to reduce the difficulty of embedding the multilayer winding into the iron core and at the same time avoid the damage of the iron core to the insulating paint surface of the multilayer winding has become a technical problem to b...
