In addition, if there is a description of "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between the various embodiments can be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not be within the protection scope of the present invention.
Fig. 1 is a partial structural schematic view of a stator of a flat-wire motor according to an embodiment of the present invention. In fig. 1, the stator of the flat wire motor may include a plurality of linear segment conductors 01, a commutation conductor 02, an outgoing wire 03, and a hairpin end 04.
As shown in fig. 1, each of the straightly-line conductors 01 may be arranged in parallel and divided into at least two groups. Each set of straightaway conductors 01 may be used in series with each other to act as the main line in the stator. The hairpin end 04 may be connected to one end of two adjacent straight-line conductors 01 in the same group. One end of the outgoing line 03 can be connected with the other end of the straight-line conductor 01, and the other end can be bent towards the periphery of the coil winding to be used for external connection to external connection voltage. The commutating conductor 02 may be connected to the other ends of two adjacent straight-line segment conductors 01 in the same group.
In the stator shown in fig. 1, the linear section conductors 01 may be arranged side by side in various forms depending on the shape of the stator casing. In one example of the present invention, the straight-line segment conductors 01 may be arranged in a vertical direction; in another example of the present invention, the straight line conductors 01 may be juxtaposed in the same oblique direction.
Based on the coil structure of the stator shown in fig. 1, the straight-line segment leads 01 are adopted to form a main circuit, the reversing conductor 02 and the hairpin end 04 are combined to be connected in series with each straight-line segment lead 01, and meanwhile, the other end of the outgoing line 03 is bent towards the periphery of the coil winding, so that the outgoing line 03 can be arranged on the same outer side of the straight-line segment leads 01. When wiring, the operation of external voltage can be completed only by arranging the wiring terminal at the outer side of the stator. Compared with the conventional outgoing lines which are respectively arranged on the inner side and the outer side of the circumference formed by the straight-line section leads 01 in the prior art, the coil structure of the stator overcomes the technical defect that the design volume is increased due to the fact that the stator needs to be wired from the bottom and the outer side simultaneously during wiring in the prior art, and the coil height of the motor stator is reduced.
In one embodiment of the present invention, the stator may further include a stator core 10 in order to fix the coil of the stator as shown in fig. 1. As shown in fig. 2, the stator core 10 may be a cylindrical housing with a hollow top and a hollow bottom, and a rectangular groove 11 for accommodating the linear conductor 01 may be formed in an inner wall of the cylindrical housing. Wherein, the specific number of the rectangular slots 11 can be determined according to the length of the coil of the stator. In one example of the present invention, the number of the rectangular grooves 11 may be 48. And the 48 rectangular grooves 11 can be uniformly distributed on the inner wall of the cylindrical shell. In addition, considering that the adjacent straightaway conductors 01 need to be insulated from each other, 2 straightaway conductors 01 may be installed in each rectangular slot 11, and the 2 straightaway conductors 01 may be disposed near the bottom and the opening of the rectangular slot, respectively. Further, since the stator core 10 is generally formed by pressing silicon steel, in order to insulate the linear conductors 01 from each other and insulate the linear conductors 01 from the stator core 10, insulating paper may be disposed in the rectangular slot 11.
In one embodiment of the present invention, to facilitate the connection of the commutation conductors 04 and the hairpin ends 01, the straight-line conductors 01 may be arranged in a cylindrical shell, and each group of straight-line conductors 01 is disposed at an interval. The commutation conductor 02 may include two straight conductive lines having opposite inclination directions and a bridge line for connecting the two straight conductive lines, and the two straight conductive lines are connected to the other ends of the adjacent two straight line segment conductors 01, respectively. In this embodiment, since the straight conductor connected to the straight section conductor 01 on the commutation conductor 02 is in an oblique direction, the height of the wiring is further reduced compared to a conventional vertical wiring. In addition, because the inclination directions of the two straight wires connected with the two straight-line conductors 01 are opposite, the influence of a magnetic field between the wires is reduced, and the suppression current generated by magnetic induction is reduced.
Since the conventional motors are all alternating current motors, and the external connection voltage is a three-phase voltage, in one embodiment of the present invention, the outgoing lines 03 may be three groups, and each group of the outgoing lines 03 may be two, and each outgoing line is used for accessing or deriving one phase of the three-phase voltage.
In one embodiment of the utility model, the stator may also include a neutral row 05, as shown in fig. 1. The neutral row 05 may wrap around the circumference formed by the commutation conductors 02 to isolate the wires exposed to the outside of the stator core 10 from the outside.
In this embodiment, as to the specific structure of the card end 04, in the case of being able to connect adjacent linear conductors 01 in the same group, there may be a variety of structures known to those skilled in the art. Such as a U-shaped member, etc., as shown in fig. 3. In one example of the present invention, the hairpin end 04 may also be of similar construction to the commutation conductor 02.
In this embodiment, in order to ensure the stability of the connection between the linear section conductor 01, the commutation conductor 02, the outgoing line 03 and the hairpin element 04, the linear section conductor 01, the commutation conductor 02, the outgoing line 03 and the hairpin element 04 may be connected by soldering.
Based on the structural schematic diagrams of the partial stators shown in fig. 1 to 3, after the respective components are combined, the schematic diagram of the resulting stator is shown in fig. 4.

Each set of straightaway conductors 01 may be used in series with each other to act as the main line in the stator.

One end of the outgoing line 03 can be connected with the other end of the straight-line conductor 01, and the other end can be used for externally connecting to external wiring voltage. The commutating conductor 02 may be connected to the other ends of two adjacent straight-line segment conductors 01 in the same group.

When wiring, the operation of external voltage can be completed only by arranging the wiring terminal at the outer side of the stator. Compared with the conventional outgoing lines which are respectively arranged on the inner side and the outer side of the circumference formed by the straight-line section leads 01 in the prior art, the coil structure of the stator overcomes the technical defect that the design volume is increased because the stator needs to be wired from the bottom and the outer side simultaneously during wiring in the prior art.

Further, since the stator core 10 is generally formed by pressing silicon steel, in order to insulate the linear conductors 01 from each other and insulate the linear conductors 01 from the stator core 10, insulating paper may be disposed in the rectangular slot 11.
