Self-Bonding Lamination Stacks in China
Full-face bonding — our most non-damaging technique in producing stator and rotor cores.
Self-bonding lamination stacks, also known as full-face bonding, offer exceptional performance and reliability in motor manufacturing. This advanced joining technique ensures enhanced structural integrity, reduced vibration, and superior thermal and electrical conductivity.
Self-bonding provides a cleaner and more environmentally friendly solution by eliminating the need for interlocking or welding. We also provide glue bonding lamination stacks.
Self-Bonding Electrical Steel Laminations Technology
Self-bonded motor core is an innovative stator core manufacturing process. In fact, self-bonded iron core can be regarded as a variant of the bonded iron core.
- It uses a special functional coating to tightly bond the stator core pieces to achieve an integral connection. Through the self-bonding process, the structural strength and geometric tolerance of the stator core can be effectively improved.
- The key to this lamination bonding process is the correct selection and use of self-adhesive coatings, as well as strict control to ensure the quality and stability of the stator core.
- The self-bonded core process uses special coatings and high-temperature curing to tightly bond the core sheets, thereby significantly improving the strength of the overall structure.
Self-Bonding Lamination Stacks Products
Ultra-thin electrical steel sheets are difficult to form riveting points or interlocking points, and laser welding may cause local conduction, which is detrimental to motor performance. Therefore, self-bonded iron cores have become an ideal choice to solve the problem of lamination and assembly of ultra-thin silicon steel sheets.

3. Maintenance of Magnetic Properties
Backlack bonding preserves the magnetic properties of the laminations, ensuring optimal performance and efficiency of the motor.
Conventional stacking techniques for electrical steel lamination stacks
Laser welding
This technique uses a high-powered laser to weld the laminations together at specific points. Laser welding provides a strong bond and precise alignment but can introduce localized heating.
Interlocking
Interlocking involves creating tabs and slots on the edges of the laminations, allowing them to snap together without the need for additional bonding agents.
Riveting
Riveting uses mechanical fasteners to hold the laminations together. This method is reliable and easy to implement but can add weight and create stress points within the stack.
FAQs
Ensuring the consistency of coating thickness on the surface of the silicon steel sheet is a primary challenge. Additionally, managing the storage and timeliness of bonding varnish demands precision processing and testing equipment. These factors are crucial to maintaining the high-quality standards and performance of self-bonding lamination stacks.
The adhesive materials of self-bonding motor cores are typically EB540, EB546, EB548, EB549, and EB549 fast.
EB549 and EB549 fast are primarily used in new energy vehicle drive motors and small to medium-sized motor cores, providing excellent performance and reliability in these applications.
Self-bonding lamination stacks are most commonly used in new energy vehicle motors. They are also ideal for various other applications, including industrial motors, traction motors, renewable energy systems, and high-performance electric motors, offering enhanced efficiency, reduced noise, and improved durability across different sectors.
