An EV drive motor core is a critical component in electric vehicles (EVs), responsible for converting electrical energy into mechanical energy to drive the vehicle's wheels. The core typically consists of laminated steel sheets stacked together to form the stator and rotor, which are integral parts of the electric motor. The design and materials used in the core influence the motor's efficiency, torque, and power output. Advanced manufacturing techniques and materials, such as high-performance steels or soft magnetic composites, are often used to optimize performance, reduce energy losses, and improve the overall efficiency of the electric drivetrain.

Electric Vehicle Drive Motor Core Industry Trends and Innovation

• High-Performance Electrical Steel: Innovations in non-oriented electrical steel (NOES) are enhancing motor efficiency by reducing core losses. High-grade NOES is increasingly being used in traction motor cores to improve power density and thermal management, essential for optimizing EV performance.
• Rare Earth Alternatives: Due to the high cost and supply chain risks associated with rare earth elements, there is a growing focus on developing alternatives. Research into ferrite-based and other non-rare-earth materials for magnets is advancing, aiming to maintain or even improve motor efficiency without relying on rare earth elements.
• Advanced Lamination and Bonding: Interlocking and bonding techniques for motor core laminations are being refined to improve motor efficiency and durability. Laser welding and adhesive bonding are being adopted to create stronger, more precise laminations, reducing energy losses and improving the motor's electromagnetic properties.

Electric Vehicle Drive Motor Core Market Drivers and Challenges

• Global EV Adoption: The increasing sales and production of EVs globally are directly boosting the demand for traction motor cores. Major automotive markets, including China, Europe, and the U.S., are seeing significant growth in EV sales, which is expected to continue as more affordable and technologically advanced models are introduced.
• Localized Production: To mitigate supply chain risks and reduce dependency on certain regions for critical materials, manufacturers are localizing production of motor cores and sourcing raw materials from more diverse and reliable suppliers. This trend is particularly prominent in Europe and North America.

Electric Vehicle Drive Motor Core Market Challenges

• Material Shortages: The supply chain for key materials like rare earth elements and advanced steels can be constrained by limited availability, long lead times, and geopolitical tensions. These constraints can lead to production delays and increased costs, affecting the overall supply of traction motor cores.
• Intense Competition: The EV traction motor core market is highly competitive, with numerous players vying for market share. This competition puts pressure on manufacturers to continuously innovate while keeping costs low, which can strain resources and margins.

Global Electric Vehicle Drive Motor Core Market Analysis by Type

Automotive drive motor cores are mainly divided into Interlocked Motor Core, Welded Motor Core and Bonded Motor Core; among them, Interlocked Motor Core and Welded Motor Core are the most common types on the market, accounting for 62.6% and 26.4% of the market share respectively in 2023; as an advanced process technology, the only companies that have the ability to mass-produce Bonded Motor Core are Mitsui High-tec, EuroGroup Laminations, POSCO Mobility Solution, Wuxi Long Sheng Technology, Tempel Steel and Kuroda Precision.

• Interlocked Motor Core：An interlocked motor core is produced using a progressive die equipped with an automatic stacking and riveting technology. The formation process involves aligning the raised riveting point of the upper lamination with the corresponding recessed hole in the lower lamination at the blanking station. When the upper lamination is pressed by the punch, the friction between the lower lamination and the die wall creates a reactive force, causing the two laminations to interlock. Through continuous high-speed stamping, a precisely stacked core of a certain thickness is formed. The interlocking points on the laminations can be cylindrical, V-shaped, L-shaped, trapezoidal, and other forms.
• Welded Motor Core：A welded motor core is assembled by connecting laminations through welding techniques. Common methods include TIG welding, gas shielded welding, and resistance welding, which offer advantages such as mature processes, low costs, minimal requirements for lamination precision, and low equipment demands. However, the drawbacks are significant: a large heat-affected zone can reduce motor performance, the process is not environmentally friendly, it requires a high level of skill from workers, and the appearance may be flawed with rough weld seams. Currently, laser welding can mitigate some of these drawbacks, but it is primarily used for small-sized cores.
• Bonded Motor Core：A bonded motor core uses adhesive to join the laminations, replacing traditional welding and interlocking methods. The purpose of this improvement is to enhance the motor's electromagnetic performance and reduce iron losses in the stator and rotor cores. Bonded cores are particularly suitable for ultra-thin laminations, as the adhesive can bond the stack without causing deformation that often occurs with lamination. The adhesive between the steel sheets forms an insulating layer, significantly reducing electromagnetic losses. Additionally, bonded cores offer improved vibration resistance and waterproofing.
