Problems solved by technology

[0003] However, due to the flat copper wire material used in the flat wire motor for winding, it still has high technical difficulties in the manufacturing process
Especially at the junction of the solder joints of the windings, it is necessary to bend multiple flat copper wires at the solder joints to different degrees, which is difficult to bend and takes a long time, and will seriously damage the original insulation and copper of the flat copper wires. line performance

Embodiment Construction

[0017] The concrete implementation method of the present invention is as follows:

[0018] like Figure 1-3 As shown, the stator structure of a flat wire motor is composed of a stator core 1 made of magnetic steel sheets, a stator winding 2 wound by flat copper wires, copper outlet terminals 6 and bus bars 3, and the stator winding is made of flat copper The wire is wound, and the cross-sectional area of ​​the copper wire is determined by the rated power and current of the motor. The bus bar 6 is fixed at the solder joint of the winding, and is electrically connected with the solder joint by soldering.

[0019] The bus bar 5 is composed of an insulating base 3 and a copper bar 4 , the insulating base 3 is made of polyethylene, the copper bar 4 is made of brass, and the copper bar 4 is inserted inside the insulating base 3 .

[0020] The insulating base 3 has an arc-shaped groove structure as a whole, and is composed of an insulating base shell 11, an insulating base groove 10...

Abstract

The invention discloses a stator structure of a flat wire motor, which has the advantages of simple welding process of a winding node and avoiding damage to the copper wire caused by bending of the flat copper wire. The stator structure of the flat wire motor comprises a stator iron core, a stator winding, an outgoing terminal and a busbar, wherein the stator winding adopts a flat copper wire structure, and the busbar is arranged at the solder joint of the three-phase winding through cuttage and electrically connected with the solder joint.

Description

technical field [0001] The invention relates to a motor stator structure, in particular to a flat wire motor stator structure wound by flat copper wires. Background technique [0002] Flat wire motors should be successfully applied in many industrial fields such as hydropower and wind power. In recent years, with the market expansion and technological breakthroughs of new energy vehicles, flat wire motors have also been gradually applied to the field of new energy vehicle drives. Compared with traditional round wire motors, flat wire motors have higher power density, better reliability and lower failure rate. At present, advanced new energy vehicle companies such as Prius and Tesla have successfully applied flat wire motors to their own vehicles and successfully realized industrialization. At home, various enterprises in our country are also stockpiling a large number of technologies and technological capabilities related to flat wire motors. [0003] However, due to the f...
