[0002] The stator flat wire is flat in shape, usually with a rectangular or nearly rectangular cross-section. This shape allows the flat wire to be arranged more closely in a limited space, thereby improving the space utilization of the motor stator winding. Since the flat wire can be arranged more closely, more conductors can be accommodated in the same space, thereby increasing the number of turns and current carrying capacity of the winding, which helps to improve the power output of the motor and achieve higher power density. In the drive motor of new energy vehicles, the use of stator flat wire technology can significantly improve the power and torque of the motor without increasing the volume of the motor, meeting the vehicle's demand for high-performance power systems.

[0003] However, in the production process of motor stators, the flat wire needs to be accurately clamped and fed. The existing stator flat wire feeding mechanism often has problems such as unstable clamping, low feeding accuracy, and inconvenient operation, which affects the production quality and efficiency of the stator.
