Flat wire motor X-pin winding technology

Flat wire motor X-pin winding technology is a relatively advanced technology. Its main function is to improve the efficiency and power density of the motor, while also reducing the noise and vibration of the motor. In terms of applications, X-pin winding technology is mainly used in electric vehicles, medical equipment, aerospace, etc. These application scenarios have higher performance requirements for motors and require the use of more efficient and reliable motors to meet their performance requirements.

X-pin winding is a type of flat wire motor. Currently, the common flat wire motors on the market include I-pin and H-pin. The common point is that a small straight section needs to be left in the welding section, which will increase the height of the stator winding end. X-pin removes the straight line segment and reduces the height of the end to make the motor stator more compact. Compared with H-pin and I-pin, the end height of X-pin is lower, which shows that the size of the motor can be further reduced and the power density can be further improved.

X-Pin winding is named after the two copper wires overlapped at the solder joint to form an "X" shape. X-pin was developed on the basis of I-pin and Hair-pin processes. The winding forming process, The head shape of the solder joints and the welding process of the solder joints are different, but the ultimate goal is to shorten the height of the winding end.

At present, scholars and engineers at home and abroad are constantly researching and improving X-pin winding technology to further improve its performance and application scope. For example, new materials and manufacturing processes are used to optimize the structure of the X-pin winding, improve its heat dissipation performance and improve its mechanical strength, etc. These studies and practices have laid a solid foundation for the further development and application of X-pin winding technology.
