Automotive Motor Lamination Market Size & Share Analysis - Growth Trends and Forecast (2027 - 2032)

Market Trends and Insights

Global Electrified-Vehicle Motor Production Expansion

Electric-vehicle motor production is increasing the addressable volume for precision motor cores. The GEM Detroit Region projects U.S. e-motor output will rise from 3.2 million units in 2024 to 14.1 million units by 2030. It also expects e-motors to account for 61% of U.S. vehicle output by 2030 ^[1]. This expansion supports the automotive motor lamination market because each traction motor requires a stator and rotor core set. The opportunity is narrower for independent suppliers where vehicle makers retain or build captive drive-unit capacity. Local production investments can therefore expand core demand while also intensifying competition for third-party nominations. The practical result is that capacity growth does not automatically translate into equal access for all lamination suppliers. Companies that already meet program quality and timing requirements are better positioned to receive the resulting work.

Higher Motor Speed and Power Density Requirements

Traction motors operating above 15,000 rpm require electrical steel with controlled core loss at higher frequencies. This raises the value of stamping accuracy, stack geometry, and joining quality for hairpin motor programs. RWTH Aachen University reports that hairpin stator lines run at 150,000 to 200,000 units per year, with continuous hairpin processes reaching mechanical slot fill factors of up to 90% ^[2]. A 2025 IEEE review identifies lamination stack geometry as a constraint on further efficiency gains in continuous hairpin winding ^[3]. The automotive motor lamination market therefore favors suppliers that work with motor engineers early in program development. Early technical involvement also gives a supplier time to align die design, material behavior, insulation needs, and stack tolerances before production begins. This reduces the risk that a core design will need costly changes after a vehicle program is approved. Feintool states that its glulock technology supports laminations as thin as 0.1 mm and can improve motor efficiency by up to 15% within the same motor envelope.

Shift Toward Thinner Non-Grain-Oriented Electrical Steel

Vehicle makers are pursuing thinner non-grain-oriented steel to reduce core losses and help extend electric driving range. thyssenkrupp Steel commissioned an annealing and isolating line in Bochum in January 2025 as part of a EUR 300 million site investment. The line can produce more than 200,000 metric tons of NGO electrical steel annually, including 0.2 mm sheets with a minimum yield strength of 420 MPa. ArcelorMittal’s Mardyck electrical-steel line has 200,000 tons of annual capacity, and its USD 1.2 billion Calvert, Alabama line, with up to 150,000 tons per year, remains under construction, with first production expected in the second half of 2027. In the automotive motor lamination market, the shift below 0.25 mm requires changes to progressive-die tooling and strengthens the case for adhesive bonding. These requirements may favor suppliers with proven thin-gauge processes over firms dependent on legacy interlocking methods.

Rising Auxiliary-Motor Content per Vehicle

Electrified vehicles use more auxiliary motors for electric power steering, pumps, cooling fans, HVAC compressors, and brake boosters. Auxiliary motors are expected to grow at a 13.32% CAGR through 2032, reflecting this broader motor count per vehicle. The APC UK expects European electric motor demand to more than triple during the next decade and projects permanent magnet synchronous motors to retain more than 60% share. IEC 60034-30-1:2025 introduced the IE5 efficiency class in December 2025, reinforcing demand for efficient motor systems. The automotive motor lamination market can gain volume from these systems even when traction-motor production differs across vehicle platforms. Feintool’s work on cooling-fan motor cores also shows that precision auxiliary-core capability can serve adjacent applications using similar manufacturing assets.

Volatility and Limited Availability of High-Grade Non-Grain-Oriented Electrical Steel

High-grade NGO electrical steel remains a material constraint for suppliers serving electric-drive programs. The requirement for low core loss and thin gauges limits the number of suitable steel grades for high-speed motors. The IEC 60034-30-1:2025 IE5 efficiency class adds a compliance factor that favors premium electrical steel. Price changes in silicon and alloy inputs also affect the economics of supply agreements when contracts allow material pass-through. New capacity in Germany, France, and the United States can improve regional availability but does not remove the need for qualified grades. The automotive motor lamination market is exposed when limited material supply constrains production schedules or narrows supplier margins. This is especially relevant where a motor program depends on a qualified steel grade and cannot readily switch materials without renewed testing. It increases the value of long-term material relationships and supply planning.

Capital Intensity of Progressive Dies, High-Speed Presses, and Inspection Systems

Modern traction-core programs need purpose-built progressive dies, high-speed presses, automated handling, and inline measurement. These investments are made before production revenue begins and are tied closely to a specific motor design. Hairpin-compatible core production also requires tight dimensional control and repeatable stack performance. Suppliers may need controlled-atmosphere annealing and additional inspection equipment to meet automotive requirements. The investment burden makes it harder for small firms to enter the automotive motor lamination market. It also increases the value of long production runs and stable vehicle-program nominations.

Automotive Motor Lamination Market Segment Analysis

Non-grain-oriented silicon steel accounted for 66.63% of the automotive motor lamination market share in 2026. Its position reflects an established balance of performance, cost, and compatibility with high-speed progressive-die stamping. The material serves a range of auxiliary and traction motor applications. Cobalt alloys remain concentrated in extreme-performance uses that require saturation magnetization above 2.3 T. Nickel alloys are the fastest-growing material segment at a 12.78% CAGR through 2032. Their use is linked to 800 V traction motors where standard NGO steel can face unacceptable eddy-current losses.

The material mix is becoming more specialized as motor speed and power density increase. A 0.10 mm B10AHV900M ultra-thin grade was introduced for traction motors above 15,000 rpm in May 2025, indicating the direction of material development. Thin grades can improve high-frequency performance but require capable stamping and joining processes. This makes material selection a manufacturing decision as well as a motor-design decision. A grade that performs well magnetically must also run reliably through the die, insulation, stacking, and handling steps. Suppliers need to assess both considerations before committing to a production method. The automotive motor lamination industry has opportunities in premium applications where grade qualification and processing know-how are decisive. Standard NGO grades are likely to remain the largest-volume option because they meet broad application requirements at a workable cost.

The 0.2-0.35 mm band held 61.26% of the automotive motor lamination market share in 2026. This gauge range remains a common engineering choice for current traction motors and premium auxiliary systems. It balances manageable processing with core-loss performance. Less than 0.2 mm is the fastest-growing thickness segment, with a 13.05% CAGR through 2032, as high-speed traction designs adopt ultra-thin grades. More than 0.35 mm remains relevant for lower-speed auxiliary motors where standard gauges are suitable.

The thickness mix does not move in one direction across all motor types. HVAC systems, pumps, and cooling fans add core volume that can continue to use thicker gauges. Thin material has a higher risk of yield loss during stamping, especially for complex geometries. Feintool states that its adhesive-based process allows series production at 0.1 mm and can improve efficiency by up to 15%. This makes adhesive joining a practical route for the thin-gauge part of the automotive motor lamination market. Suppliers need to manage scrap and tooling life while meeting the tighter tolerances required by these grades.

Stamping accounted for 78.73% of the automotive motor lamination market share in 2026 and is forecast to grow at a 13.01% CAGR through 2032. Its lead reflects the scale and repeatability of progressive-die production. A new motor design generally requires a dedicated die set. Re-sourcing during production is difficult after a process has been validated by an OEM. Laser cutting and other methods serve prototypes and low-volume applications where dedicated die investment is not justified.

Stamping increasingly includes bonding as part of the production process rather than a separate downstream activity. Worthington Steel’s Tempel introduced FSB Full Surface Bonding in October 2025. The company says the process applies adhesive at 2-4 microns compared with 5-14 microns in conventional bonding and has received production approval at multiple automotive OEMs. This improves the relevance of high-volume stamping for quiet and efficient motor designs. The automotive motor lamination market rewards suppliers that combine tooling expertise with process control for adhesive application. Cost-effective prototype methods will remain necessary, but they do not challenge stamping’s high-volume position.

Interlocking held 67.28% of the automotive motor lamination market share in 2026. It remains widely used because it fits established progressive-die tooling and supports high production rates. Bonding gains relevance as material gauges move below 0.25 mm. Mechanical interlocking can be less reliable for thin laminations exposed to demanding operating loads. Welding is the fastest-growing stacking method at a 13.15% CAGR through 2032. It supports segmented-core arrangements and post-stack joining requirements that interlocking cannot always meet.

The stacking-method choice depends on motor geometry, grade thickness, and noise or loss requirements. Nippon Steel received U.S. Patent 12,261,482 in March 2025 for adhesive regions on lamination teeth that provide axial tensile strength above 20 MPa for high-speed rotor use. POSCO International began mass production in December 2025 at its Brzeg facility in Poland using self-bonding adhesive lamination technology. These developments show that bonding is becoming a key option for automotive core programs. The automotive motor lamination market will retain interlocking at scale while expanding alternative methods for thinner and more complex core designs.

Traction motors held 65.48% of the automotive motor lamination market share in 2026. Every electrified drivetrain needs at least one primary drive motor with a stator and rotor core set. This ensures a large core requirement across battery electric and hybrid platforms. Auxiliary motors are forecast to grow at a 13.32% CAGR through 2032. Their growth is linked to increasing use of electric power steering, oil pumps, cooling fans, HVAC compressors, and brake boosters. The automotive motor lamination market size for auxiliary motors expands as vehicle electrification adds these systems.

Motor suppliers are applying stricter efficiency expectations to auxiliary systems. IEC 60034-30-1:2025 adds the IE5 efficiency class to the motor-efficiency framework. This reduces the scope for lower-grade material choices in some auxiliary applications. It also creates demand for consistent core quality across several smaller motor designs. Feintool’s cooling-fan motor core work demonstrates that automotive-grade auxiliary-core capability can be used in nearby industrial markets. The automotive motor lamination industry benefits from this wider equipment base because it can improve asset utilization beyond traction programs.

Stator lamination held 71.23% of the automotive motor lamination market share in 2026. The stator contains a larger annular structure and tooth array than the rotor in many motor designs. This higher material content supports its revenue position. Rotor lamination is forecast to grow at a 13.37% CAGR through 2032. Buried permanent magnet topologies at higher speeds require thin bridges and web features with close dimensional tolerances. The automotive motor lamination market size for rotor lamination is therefore closely tied to high-performance traction designs.

Rotor design creates a different manufacturing challenge from stator production. A 2026 Frontiers review identifies the lamination stack as a combined magnetic and production challenge in hairpin motors. Early cooperation between motor designers and stampers can reduce downstream production risks. The automotive motor lamination market therefore gives added strategic value to suppliers that can support rotor design validation. Stator volume will continue to dominate, but rotor complexity can determine the required technology level.

Battery electric vehicles held 58.36% of the automotive motor lamination market share in 2026 and are forecast to grow at a 13.26% CAGR through 2032. ICE vehicles accounted for 16.52%, with demand mainly associated with auxiliary motors for steering, pumps, cooling fans, and starters rather than traction cores. A dual-motor battery electric vehicle needs traction-core sets that contain many individual electrical steel laminations. Hybrid and plug-in hybrid platforms continue to support demand as manufacturers manage fleet carbon dioxide compliance.

Vehicle mix has a direct effect on supplier revenue per core set. Battery electric core sets carry higher value than hybrid core sets, so higher hybrid volumes may not generate equivalent value growth for premium suppliers. The automotive motor lamination market benefits most when higher-content battery electric platforms expand. ICE volume continues to provide a meaningful base through auxiliary cores. Suppliers should therefore balance programs across conventional, hybrid, and battery electric platforms rather than assess demand using vehicle count alone.
