POSCO has partnered with Hyundai Motor and eight other industry, academic and research organisations to develop next generation high efficiency electrical steel for electric vehicle drive motors. The collaboration aims to improve EV energy efficiency, extend driving range and strengthen South Korea's leadership in advanced automotive materials.
Key Highlights
- Consortium: 10 organisations led by POSCO, including Hyundai Motor
- Technology Focus: Development of 6.5% silicon content wide electrical steel sheets
- Objective: Improve efficiency of EV drive motors and reduce energy losses
- Project Support: Backed by South Korea's Ministry of Trade, Industry and Energy and the Korea Institute for Advancement of Technology
- Application: High efficiency electric vehicle motors with improved driving range and performance
Advanced Electrical Steel to Power the Next Generation of EVs
POSCO has launched a national research initiative with Hyundai Motor, automotive component manufacturers and leading research institutions to develop next generation electrical steel specifically designed for electric vehicle drive motors. The project will focus on producing 6.5% silicon content wide electrical steel sheets, a material capable of significantly reducing iron loss during high speed motor operation while improving overall motor efficiency.
Electrical steel is one of the most critical materials used in electric motors, directly influencing efficiency, heat generation and vehicle range. By improving the magnetic properties of the steel, automakers can develop motors that consume less energy while delivering higher performance, enabling EVs to travel longer distances on a single battery charge.
Industry Collaboration to Accelerate Commercialisation
The consortium brings together expertise from across the automotive value chain, including steel producers, vehicle manufacturers, component suppliers and research organisations. POSCO will lead material development while Hyundai Motor will evaluate the performance of the newly developed electrical steel in electric vehicle drive motors under real world operating conditions.
The project is expected to accelerate commercialisation by integrating material development, motor manufacturing and vehicle validation within a single collaborative framework. Such partnerships are becoming increasingly important as global automakers compete to improve battery efficiency and extend EV driving range without significantly increasing battery size or cost.
Innovation Supports the Global Shift Towards Electric Mobility
As electric vehicle adoption accelerates worldwide, demand for high performance electrical steel continues to grow rapidly. Unlike conventional steel, electrical steel is specifically engineered to minimise energy losses in electric motors and transformers, making it a strategic material for the automotive and clean energy sectors.
The development of higher silicon electrical steel represents a significant technological advancement that could improve motor efficiency, reduce power consumption and enhance vehicle performance. The initiative also aligns with South Korea's broader strategy of strengthening its competitiveness in advanced manufacturing and sustainable mobility technologies.
Market Impact
The collaboration highlights the growing importance of specialised steel grades as the automotive industry transitions towards electrification. Rising demand for electrical steel is expected to create new opportunities for steelmakers capable of producing high value added products, while reducing dependence on conventional commodity steel.
For the steel industry, this trend signals a gradual shift towards advanced automotive materials with higher margins and stronger long term demand. It also presents opportunities for equipment manufacturers, technology providers and suppliers involved in precision steel processing.
Outlook
The partnership between POSCO and Hyundai demonstrates how collaboration across the steel and automotive industries can accelerate innovation in electric mobility. As governments tighten emission regulations and global EV adoption continues to rise, demand for advanced electrical steel is expected to grow significantly. Successful commercialisation of this technology could not only improve the efficiency of future electric vehicles but also reinforce South Korea's position as a global leader in advanced steel and automotive manufacturing.
