EV Manufacturing Expansion in 2026 Is Reshaping Electrical Steels Demand for High-Speed Traction Motors

Electrical steel is becoming an increasingly important material in the transition towards electrified transportation and modern power infrastructure. Unlike conventional steel, it is engineered with specific magnetic properties that allow electrical energy to be converted and transmitted with lower energy losses.

Its applications extend across power transformers, industrial motors, electric vehicle traction systems, wind turbines, generators and high-frequency electrical equipment. As electricity consumption rises and industries replace conventional machinery with energy-efficient alternatives, manufacturers are placing greater emphasis on thinner steel sheets, improved magnetic permeability and reduced core losses.

Two Material Grades Serving Different Industrial Requirements

• The market operates around two principal product categories, each serving a distinct engineering requirement.
• Grain-oriented electrical steel (GOES) is primarily used in transformer cores because its magnetic properties are concentrated along the rolling direction.
• Non-grain-oriented electrical steel (NGOES) offers more uniform magnetic characteristics across different directions, making it suitable for rotating equipment such as motors and generators.
• According to Nippon Steel’s technical disclosures, these materials support improvements in transformer efficiency, motor performance and equipment miniaturisation.

The Transformer Supply Chain Is Creating a New Material Priority

The growing requirement for electricity infrastructure is bringing electrical steel into sharper focus. Transformers depend on specialised core materials to manage magnetic flux and minimise energy losses during power conversion. In October 2026, the US Department of Energy highlighted shortages of electrical steel for transformer cores as an important constraint affecting domestic grid-equipment manufacturing.

The department also reported that imported products supply approximately 80% of US power transformers and 50% of distribution transformers. Its Grid Supply Chain Program carries up to USD 375 million in authorised funding to support supply-chain improvements. This situation creates opportunities for electrical steel producers to strengthen domestic manufacturing, develop alternative material sources and support transformer manufacturers facing procurement delays.

EV Traction Motors Are Raising the Specification Bar

Electric vehicle manufacturers are increasingly demanding electrical steel that can support higher motor efficiency, compact designs and improved performance at elevated rotational speeds. High-grade NGOES is particularly important because magnetic losses within the motor core influence energy consumption and driving range.

A significant development emerged on June 15, 2026, when POSCO announced a collaboration involving Hyundai Motor and eight other organisations to develop 6.5% silicon-content wide electrical steel sheets and advanced EV motor technologies. This initiative highlights growing interest in materials with improved high-frequency magnetic characteristics.

Wind Generation and Power Electronics Are Expanding Application Boundaries

• Electrical steel demand is also connected to wind turbine generators, industrial drives and high-frequency reactors.
• These applications require materials capable of maintaining magnetic performance under different operating conditions.
• JFE Steel’s research into 6.5% silicon electrical steel for high-frequency applications demonstrates how manufacturers are developing specialised grades for next-generation electrical equipment.
• Its JNEX material targets the 400 Hz to 10 kHz frequency range, while JNHF addresses applications between 5 kHz and 100 kHz. Such developments are particularly relevant as power conversion systems become more sophisticated.

India’s Power Infrastructure Is Creating Additional Manufacturing Opportunities

India is becoming an important market for electrical steel because of its expanding electricity network, transformer requirements and electric mobility ambitions. The Indian Electrical and Electronics Manufacturers’ Association reported that 54,597 MW of generation capacity was added during FY2025-26, while 12,139 circuit kilometres of transmission lines and 1,13,013 MVA of transformation capacity were added.

Power transformer industry growth reached 31.6% during the same financial year. These developments indicate increasing requirements for transformer components and specialised electrical materials.

Production Technology Is Becoming a Competitive Differentiator

Electrical steel manufacturing requires precise control over silicon content, rolling thickness, annealing conditions, grain orientation and surface insulation coatings. Even small variations can influence magnetic losses, punching performance and finished-core quality.

Nippon Steel’s investment programme and POSCO’s advanced electrical steel development demonstrate how producers are prioritising higher-grade products rather than relying exclusively on conventional steel output. The ability to manufacture thin-gauge materials consistently will become particularly important for EV motors and high-efficiency transformers.

The Next Industrial Shift Will Be Defined by Magnetic Performance

The electrical steels industry is entering a period in which product engineering will become as important as production capacity. Transformer manufacturers require low-loss GOES, while EV manufacturers are seeking advanced NGOES grades that improve motor efficiency without compromising mechanical strength.

At the same time, grid expansion, renewable energy integration and industrial electrification are increasing the importance of reliable material supply. Companies capable of combining advanced metallurgy, precision processing and consistent quality will be better positioned to participate in the next generation of global electrical infrastructure.
