The purpose of the utility model can be realized through the following technical scheme:
according to the utility model discloses an aspect provides a coreless motor winding, including the multislot winding coil, every slot winding coil includes a power lead-out wire, the winding still including setting up the winding of striding the groove between the non-adjacent winding coil of homophase.
As a preferable technical solution, the cross-slot winding is a connection line between winding coils which are not adjacent in phase.
As a preferable technical scheme, the connecting wire is a continuous winding wire without cutting treatment in the middle.
Preferably, the cross-slot winding is arranged at two ends of the winding coil.
Preferably, the cross-slot winding is arranged at the middle position of the winding coil.
Preferably, the cross-slot winding is a single wire.
As a preferred technical scheme, the cross-slot winding is a stranded wire.
According to another aspect of the utility model, a take motor of coreless motor winding is provided, include coreless motor winding.

1) the utility model discloses a continuous cross-slot wire winding, the winding that has significantly reduced draws the line head, and technology is simpler in the wiring of back process.
2) The utility model discloses a after the wire winding of striding the groove, need not handle middle gap bridge end of a thread, can stop because the fried tin line that middle end of a thread soldering tin brought hinders the problem, improves the quality of product.
3) The utility model discloses cancel the gap bridge end of a thread, reduce solder joint insulation processing, not only stopped because of the withstand voltage breakdown problem that solder joint insulation processing improper arouses, and simplified motor design structure, reduced motor cost.
4) The utility model discloses cross the automatic line of crossing of groove wire winding (gap bridge line) adoption efficiency, reduce the difference of the artifical reason line of wire winding in-process, the product uniformity is better.
5) The utility model discloses cross groove wire winding (gap bridge wire) and put at winding coil middle part, can keep the winding coil on, in, the unanimity of three position thickness down, in the post process thermal flattening, the coil atress is more even, and it is better to bond between the winding electromagnetic wire.

FIG. 1 is a schematic diagram of a conventional winding structure;
fig. 2 is a schematic structural diagram of the winding of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall fall within the protection scope of the present invention.
Example 1
As shown in fig. 2, the coreless motor winding comprises a multi-slot winding coil 1, each slot winding coil comprises a power outgoing line 2, and the winding further comprises a cross-slot winding 3 arranged between winding coils which are not adjacent in phase.
The cross-slot winding 3 is a connecting wire (bridge wire) between winding coils which are not adjacent in phase. The connecting wire is a continuous winding wire without shearing treatment in the middle, so that the number of winding leading-out wire ends is small, and the process is simpler in post-process wiring; meanwhile, after the cross-slot winding is adopted, the intermediate bridging thread end is not required to be processed, the problem of tin wire damage caused by tin soldering of the intermediate thread end can be avoided, and the product quality is improved.
The cross-slot winding 3 is arranged at the two ends of the winding coil, the winding is convenient and the manufacturing process is simple, or the cross-slot winding is arranged at the middle position of the winding coil, the thickness of the upper, middle and lower positions of the winding coil can be kept consistent, the coil is stressed more uniformly in the post-process hot pressing, and the winding electromagnetic wires are bonded better.
The cross-slot winding 3 is a single-stranded wire, or the cross-slot winding is a multi-stranded wire, so that the application range of the cross-slot winding is wider.
