Global Adhesive-Laminated Core Market Strategic Research Report

Scope of the Report

The global Adhesive-Laminated Core market size is predicted to grow from US$ 1,804 million in 2025 to US$ 4,138 million in 2032; it is expected to grow at a CAGR of 12.3% from 2026 to 2032.

Adhesive-Laminated Cores are motor components where the layers of the motor core are bonded together using adhesives. Unlike traditional core manufacturing methods, adhesive-bonded cores do not use welding or mechanical connections. Instead, advanced bonding processes connect the various parts of the core together, achieving higher precision and better mechanical strength. This bonding technology reduces core losses and improves motor efficiency, especially during high-frequency operation. Common adhesives include epoxy resins and polyurethanes, which provide good electrical insulation and strength. In 2025, global production of Adhesive-Laminated Cores reached approximately 17.06 million units, with an average price of US$108.1 per unit and a gross profit margin of approximately 20.43%. Downstream customers include domestic and international automotive parts manufacturers, OEMs, and motor manufacturers, such as Valeo, Bosch Group, Aldor Group, Inovance Technology, and BYD. Production Capacity: Mitsui High-Tech Co., Ltd. supplies more than 1.6 million motor cores annually for automotive applications.

With the rapidly increasing demands for efficiency, noise, power density, and reliability from new energy vehicles, robots, drones, servo systems, and high-speed industrial motors, adhesive-bonded motor cores are gradually moving from a few high-end projects into mass production applications for high-efficiency motors. While traditional splicing, welding, and riveting processes are mature, they can introduce problems such as localized stress, short circuits between laminations, magnetic performance loss, and vibration noise. Adhesive lamination, through methods like adhesive dots, full-surface bonding, self-adhesive coatings, or in-mold bonding, allows silicon steel sheets to form a monolithic structure while maintaining insulation, helping to improve core consistency, reduce losses, and enhance the mechanical stability of high-speed motors. Companies like Kuroda, Tempel, and Voestalpine are continuously advancing process verification around in-mold bonding, full-surface bonding, and self-bonded electrical steel, indicating that this technology is shifting from process innovation to supply chain capability competition.

From the demand side, new energy vehicle drive motors represent the most important growth market for adhesive-bonded motor cores. High-speed, high-power-density, and low-noise drive motors place higher demands on rotor stability, stator lamination consistency, and iron loss control, driving the upgrade of iron core manufacturing from traditional mechanical fixing to higher-precision adhesive lamination. Meanwhile, industrial servo motors, robot joint motors, drone brushless motors, medical motors, and rail transit traction motors are also driving the expanded application of adhesive-bonded iron cores. For small, high-end motors, adhesive bonding can improve structural strength and noise performance; for new energy vehicles and high-speed motors, the value of adhesive bonding lies more in reducing losses, improving reliability, and supporting the mass production of thin-gauge electrical steel.

Market challenges are concentrated on cost, material matching, and mass production consistency. Adhesive-bonded motor iron cores need to address issues such as adhesive layer thickness control, curing processes, heat resistance, oil resistance, peel strength, stamping burrs, lamination positioning accuracy, and long-term reliability verification. Compared to traditional snap-fit ​​iron cores, adhesive lamination places higher demands on molds, dispensing equipment, self-adhesive electrical steel, thermosetting curing, and online testing capabilities. Therefore, in the short term, it is mainly used in high-performance motors rather than completely replacing traditional iron cores. In the future, from 2026 to 2032, with the upgrading of electric drive platforms for new energy vehicles, the expansion of the supply of self-adhesive electrical steel, and the maturity of domestic iron core manufacturers' processes, adhesive-bonded motor iron cores will show a structural growth from high-end traction motors to industrial motors, small precision motors, and robot motors.
