All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to fig. 3, the present invention provides a high performance electromagnetic wire for motor coil winding, including a flat conductor 1, a first insulating layer 2 is wrapped outside the flat conductor 1, first insulating protrusions 3 and second insulating protrusions 4 are fixedly connected to the top and the bottom of the first insulating layer 2 at equal intervals, respectively, an outer groove 6 is arranged between two adjacent first insulating protrusions 3, and an inner groove 5 is arranged between two adjacent second insulating protrusions 4. When the flat conductor 1 is wound on a motor winding, the first insulating projections 3 and the second insulating projections 4 on the surface of the first insulating layer 2 are respectively positioned on the outer side and the inner side of the coil, and the first insulating projections 3 and the second insulating projections 4 are poorly engaged with each other to perform winding.

As shown in fig. 2, when the flat conductor 1 is wound around the coil winding, the first insulating protrusion 3 is snapped into the inner groove 5, and the second insulating protrusion 4 is snapped into the outer groove 6.

Specifically, the first insulating protrusions 3 are inserted into the inner grooves 5 between two adjacent second insulating protrusions 4, and the second insulating protrusions 4 are inserted into the outer grooves 6 between two adjacent first insulating protrusions 3, so that the first insulating protrusions 3 and the second insulating protrusions 4 are in opposite cross engagement.

As shown in fig. 1, the thickness of one side of the first insulating layer 2 is 0.045-0.1mm.

The single-side thickness of the first insulating layer 2 is set to be 0.045-0.1mm, which is beneficial to bending the flat conductor 1 firstly and can ensure that the flat conductor 1 is not excessively accumulated in the winding process secondly.

As shown in fig. 1, the thickness of the single side of the first insulating bump 3 and the second insulating bump 4 is 0.05mm.

Through setting for 0.05mm with the unilateral thickness of first insulating arch 3 and second insulating arch 4, can make things convenient for flat conductor 1 both intercrossing meshing when the winding, also can not cause pile up between them because of thickness is too high simultaneously to influence winding thickness.

As shown in fig. 1, the insulating material of the first insulating layer 2 is an aromatic polyimide composite film, and the surface of the aromatic polyimide composite film has a glue coating.

By adopting the aromatic polyimide composite film as a manufacturing material of the first insulating layer 2, a good insulating effect can be achieved, and the thickness is small.

The working principle and the using process of the invention are as follows:

first 2 twine the surface of 1, live the complete parcel in the outside of 1, then through top surface and the ground at 2

adhesion

3 and 4 respectively, make 3 and 4 and 2 fixed connection, then at 2, one deck hot melt adhesive layer is paintd on the surface of 3 and 4, when twining 1 on motor winding, the first insulation arch 3 and the second insulation arch 4 on 2 surfaces on the first insulation layer are located the outside and the inboard of coil respectively, with the mutual relatively poor meshing of first insulation arch 3 and second insulation arch 4, insert first insulation arch 3 in the inside groove 5 between two adjacent second insulation arch 4, insert second insulation arch 4 in the outer tank 6 between two adjacent first insulation arch 3 simultaneously, just so can be convenient for 1 twine, can leave certain gap between 3 and 4 and be convenient for dispel the heat, secondly 3 and 4 cross arrangement, even one side breaks, also can not directly contact between 1's inner wall and the outer wall, thereby play fine insulating effect.
