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.
