- Posco has initiated development of 6.5% silicon-content electrical steel for high-efficiency EV motors.
- Industry, academic, and research partners will jointly validate efficiency gains in real EV drive motors.
South Korea-based Posco has officially launched a new research and development initiative aimed at advancing electric vehicle motor efficiency through the development of next-generation electrical steel materials. The company held a kickoff meeting for the project titled “Development of 6.5% Silicon-content Wide Electrical Steel Sheet and Electric Vehicle (EV) Efficiency-Enhancing Core and Drive Motor Manufacturing Technologies,” marking the formal start of the program. The initiative is being supported by the Ministry of Trade, Industry and Energy (MOTIE) and the Korea Evaluation Institute of Industrial Technology (KEIT).
The project focuses on securing manufacturing technologies for 6.5% silicon-content wide electrical steel sheets, which are considered a critical material for producing high-efficiency electric motors. By enhancing the material characteristics of electrical steel used in motor cores, the participating organizations aim to improve the overall efficiency of electric vehicle drive systems. The program also includes performance validation activities to assess the effectiveness of the developed material in actual EV drive motors and measure its contribution to vehicle efficiency improvements.
Led by Posco, the collaborative project brings together ten organizations representing industry, academia, and research institutions. Key participants include Hyundai Motor Company, SL Corporation, and Polepair Electric. The consortium structure is designed to combine expertise across multiple stages of the value chain, supporting the development and commercialization of advanced motor technologies for electric vehicles.
Participating organizations will work together throughout the complete development process, spanning material engineering, core manufacturing, and motor production. This integrated approach is intended to accelerate technology readiness while ensuring that the developed electrical steel sheets can be effectively incorporated into practical EV applications. Through coordinated research and validation efforts, the project seeks to strengthen capabilities in advanced motor materials and support future improvements in electric vehicle performance and efficiency.
