The flat wire motor is characterized in that a copper wire in a stator winding adopts a flat wire, the winding is firstly made into a shape similar to a hairpin and penetrates into a stator slot, and then the end part of the hairpin is welded at the other end.

The flat wire motor and the round wire motor are different in the forming mode of copper wires, the flat wires are beneficial to improving the slot fullness rate of the motor, the slot fullness rate of the general round wire motor is about 40%, and the slot fullness rate of the flat wire motor can reach more than 60%. The improvement of the full rate of the groove means that more copper wires can be filled under the premise of unchanging the space, stronger magnetic field intensity is generated, and power density is improved. The contact area between the flat wires is large, and compared with a round wire motor, the flat wire motor has better heat conduction performance and lower temperature rise. Data show that the temperature rise of the flat wire motor is about 10% lower than that of the round wire motor. In addition, the flat wire motor can also improve the utilization rate of copper wires by saving copper materials at the end part, thereby achieving the purpose of reducing the cost.

Compared with the traditional round wire motor, the flat copper wire winding motor has obvious advantages in the aspects of efficiency, performance, heat dissipation and the like, but the manufacturing process of the winding is very complex, the copper wire is required to be made into the shape of a hairpin, and then the hairpin is inserted into a stator iron core slot to be subjected to end part twisting and welding. The complicated manufacturing process means that the difficulty of manual manufacturing is high, and a complete automatic production line is necessary to establish for batch high-efficiency production.
