TECHNICAL FIELD
[0001] The utility model relates to a kind of motors, more exactly, a kind of welding end wire flat wire motor stator. BACKGROUND
[0002] At present, the popularization of electric drive in engineering machinery market, the current drive scheme generally uses permanent magnet synchronous motor, in order to solve the problem of low slot fill rate of copper round wire winding and the demand of high speed, light weight, large torque, high efficiency and cost reduction and efficiency improvement of current host factory, flat wire motor stator becomes the most important of the technology research and development of major motor factory. For the demand of low speed and large torque, high speed and large torque in engineering machinery field, more parallel branch numbers and layers are often used in design, such as 4-way parallel 8-layer flat wire, which also causes complexity in structure arrangement, both ensuring the feasibility of technology and ensuring the cost performance. The existing motor stator generally leads out wire from crown end, which needs to set special busbar assembly at crown end, and special mold is needed for manufacturing busbar assembly, with high cost. In addition, the height of the crown end of the existing stator is too high, which is not conducive to the miniaturization of motor, and the high crown end does not contribute to the torque of motor, but reduces the efficiency of motor.

[0021] In order to make the personnel in the technical field better understand the scheme of the utility model, the following will be to the technical scheme in the embodiment of the utility model, clear, complete description is carried out to the embodiment of the utility model.
[0022] As Figures 1 to 3 As shown in the figure, the welding end outgoing line flat wire motor stator comprises a core body 1, a flat wire cluster 2 is arranged in the core body 1, the flat wire cluster 2 comprises a crown end 21 and a welding end 22, the setting direction of the crown end 21 is opposite to that of the welding end 22, and a plurality of outgoing lines 221 are connected to the welding end 22.
[0023] It should be noted that the extension direction of the outgoing line 221 is consistent with the axial direction of the core body 1.
[0024] As shown in the figure, Figure 4 and Figure 5 the number of layers of the flat wire cluster 2 is eight.
