[ detailed description ] embodiments
Referring to the accompanying drawings 1 to 8 in the specification, the present invention relates to a winding structure of a flat wire motor, which adopts a 2-way parallel connection mode and is composed of a stator core 1, a plurality of special-shaped flat wires I2, a three-phase outgoing line 3, a neutral point connecting copper bar 4, a plurality of special-shaped flat wires II5, a plurality of special-shaped flat wires III6, and the like.
The special-shaped flat wire I2, the special-shaped flat wire II3 and the special-shaped flat wire III4 are respectively assembled in the stator core 1 according to design requirements, a hairpin end 7 is formed at one side of the stator core 1, and a welding end 8 is formed at the other side of the stator core 1. The special-shaped flat wire I2 is an existing special-shaped flat wire and is not described in detail herein. After the ends of the special-shaped flat wire I2, the special-shaped flat wire II3 and the special-shaped flat wire III4 are cut, welding heads at the welding end 8 are all on the same horizontal plane, so that the design of a twisting head tool is relatively simple, and the production and the manufacture are easier.
The special-shaped flat wire II5 is of an integrated structure and can be connected in a cross-phase mode. In the present embodiment, the shaped flat wire II5 is specifically provided with 6 pieces and is formed by press molding, and includes the first wire body portion 51, the cross-phase connecting portion 52, and the second wire body portion 53 which are integrated. The cross-phase connecting part 52 is located at the hairpin end 7, connects the first line body part 51 and the second line body part 53, and connects the copper bar 4 across the neutral point, so that the winding structures are connected in a cross-phase mode. Because dysmorphism flat wire II5 strides mutually and connects through stamping forming's mode, and the switching of welding is carried out to the non-adoption traditional copper bar, has cancelled corresponding welding point to reduced the risk that leads to the motor to burn out because of welding inefficacy.
The three-phase lead-out wire 3 is welded at the hairpin end 7 and part of special-shaped flat wires III6, so that the later-period end cutting at the welding end 8 can be ensured to be neat, all welding heads are on the same horizontal plane, the design of the head twisting tool is relatively simple, and the production and the manufacture are easier. The three-phase lead-out wire 3 is divided into U, V, W three-phase lead-out wires. Each three-phase outgoing line 3 comprises a connecting copper bar 31 and two connecting flat wires 32 welded on the connecting copper bar 31. Each connecting flat wire 32 is welded with a special-shaped flat wire III6, and the total number of the welding points is 6. Meanwhile, the connection flat wire 32 has an insulation layer, so that additional insulation coating is not needed, and the production and manufacturing cost is indirectly reduced.
The utility model discloses a neutral point position of winding structure adopts neutral point to connect copper bar 4 and carries out welded connection, promptly the neutral point is connected copper bar 4 and is held 7 and another part dysmorphism flat wire III6 welding at the hairpin. In the present embodiment, three welding points 41 are arranged on the neutral point connecting copper bar 4; each welding point 41 is welded with a special-shaped flat wire III 6. The neutral point connecting copper bar 4 only needs 2, so that the using amount of the copper bar is less, and the production and the manufacture are convenient.
The utility model discloses a winding structure of flat wire motor's design principle as follows: the three-phase outgoing line 3 is designed at the hairpin end 7 to be outgoing, so that all flat lines are tidy when the ends of the welding ends 8 are cut, all welding heads are on the same horizontal plane, and the design of a twisting tool is relatively simple; the three-phase outgoing lines 3 are all connected by welding by adopting the own connecting flat wire 32, and the connecting flat wire 32 is provided with an insulating layer, so that additional insulating coating is not needed. And the phase are connected in a cross-phase manner by adopting the special-shaped flat wire II5 formed by stamping and molding instead of adopting the traditional copper bar for welding and switching, so that welding points are reduced, and the risk of burning the motor due to failure of the welding points is reduced. Except that the neutral point positions are connected by adopting two neutral point connecting copper bars 4, corresponding copper bars are cancelled at other positions, and the production and manufacturing cost of the winding is directly reduced.
The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
