New generation of X-pin flat wire motor stator winding technology

The new generation of flat wire motor stators with X-pin winding technology can overcome key technical difficulties and has outstanding leading advantages in various technical directions of the X-pin flat wire motor stator production line, helping OEMs to deliver high-quality and cost-effective products.

X-pin is named after the overlap of two copper wires at the solder joint to form an "X" shape. In the flat wire motor market, the current common winding forms are mainly hair-pin, followed by I-pin. The common point of these two winding forms is that a straight section needs to be left at the welding end, which directly increases the height of the stator winding end.

X-pin removes the straight section, lowers the height of the stator end and reduces the volume, which is more conducive to the customer's space layout of the electric drive system and the vehicle. Compared with Hair-pin and I-pin, X-pin stator copper wire reduces heat loss, while reducing volume and weight, resulting in increased power density, while maintaining the current flexible electromagnetic solution of the motor, making the "heart of the electric vehicle" "More powerful, more powerful. Furthermore, X-pin stator does not require head cutting process during the production process, which has great technological advancement and can save costs for customers.

Innovative X-pin stator high-efficiency and stable welding technology adopts a flexible laser welding architecture solution and integrates a self-developed advanced visual guidance system. The success rate of visual guidance before welding has reached 99.9%, which greatly improves welding reliability and effectively maximizes motor performance.

X-pin stator intelligent manufacturing technology provides strong support for the evolution of flat wire motor technology, actively promotes the application of X-pin technology in the new energy vehicle market, and provides customers with higher quality and more cost-effective product choices.
