Description

Technical Field

[0001] The utility model relates to the technical field of armature windings, in particular to an improved structure of a coil. Background Art

[0002] The armature winding is a component in a motor or a generator, usually composed of coils wound around the iron core of the motor or the generator. It is the place where current generates a magnetic field in the motor or induces current in the generator.

[0003] The armature winding is composed of coils with the same structure and shape. The coils are divided into single-turn and multi-turn coils. At present, during the bending process of a single-turn coil, the inner wall of the bending part bulges upward and downward during the force application process, resulting in uneven surfaces on the inner and outer sides of the bending part. When stacking single-turn coils, the contact area between the bending parts of adjacent two coils is small, affecting the processing quality of the armature winding. Therefore, we propose an improved structure of a coil to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that when stacking single-turn coils in the prior art, the contact area between the bending parts of adjacent two coils is small, affecting the processing quality of the armature winding, and to propose an improved structure of a coil.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An improved structure of a coil, including a coil body. The coil body includes two embedding parts. One ends of the two embedding parts are connected by a bending part, and connecting parts are arranged at the other ends of the two embedding parts;

[0007] The plane where the bending part is located is perpendicular to the plane where the embedding part is located, and the upper and lower surfaces of the bending part are both flat, improving the contact area between the bending parts of adjacent two coils when stacking single-turn coils, so as to improve the processing quality of the armature winding.

[0008] As a preferred technical scheme of the utility model, both sides of the embedding parts are bent in the same direction, and the included angle between both sides of the embedding parts and the center of the circle where they are located is 90°.

[0009] As a preferred technical scheme of the utility model, insulating layers are arranged on the outer walls of the embedding part, the bending part and the connecting part, and an exposed end of 30 - 35 mm is left at the outer end of the connecting part, and the exposed end is used for the wiring operation of the coil.

[0010] As a preferred technical scheme of the utility model, both sides of the connecting parts are inclined outward, and the included angle between both sides of the connecting parts is 110° - 115°.

[0011] The beneficial effects of the present utility model are as follows:

[0012] During processing, the upper and lower surfaces of the bending part of the single-turn coil are made flat, so as to increase the contact area between the bending parts of adjacent two coils when the single-turn coils are stacked, thereby improving the processing quality of the armature winding.

[0018] Referring to Figures 1 - 3 , an improved coil structure includes a coil body. The coil body includes two embedding parts 1. One ends of the two embedding parts 1 are connected by a bending part 2. The plane where the bending part 2 is located is perpendicular to the plane where the embedding part 1 is located, and the upper and lower surfaces of the bending part 2 are both flat, which increases the contact area between the bending parts of adjacent two coils when the single-turn coils are stacked, thereby improving the processing quality of the armature winding;

[0019] Among them, both sides of the embedding part 1 are bent in the same direction, and the included angle between both sides of the embedding part 1 and the center of the circle where they are located is 90°, as Figure 2 shown;

[0022] In this embodiment: during the processing of the coil, the upper and lower surfaces of the bending part 2 of the single-turn coil are flattened to increase the contact area between two adjacent coils after stacking, thereby improving the processing quality of the armature winding.
