New energy vehicles’ axial flux stator punching employs specialized stamping and rolling equipment, guided by a servo synchronous control system. This ensures precise groove stamping, consistent alignment, and diameter accuracy throughout, enhancing disc stator in electric vehicles’ performance.

Lamination bonding is a crucial process in automotive motor manufacturing, enhancing the performance and durability of motor laminations. In this context, two prevalent bonding methods are employed: gluing dot bonding and self-bonding.

Gluing dot bonding involves applying adhesive in specific dot patterns to join lamination steel, providing structural integrity and preventing delamination. This lamination bonded together method ensures precise bonding points, optimizing the overall stability of the motor.

On the other hand, self-bonding relies on the inherent magnetic properties of the laminations, allowing them to adhere to each other without the need for external adhesives. This approach minimizes the use of additional materials, streamlining the manufacturing process and reducing environmental impact.
