POSCO Develops High-Efficiency Electrical Steel Sheets to Improve EV Energy Efficiency

Ten Industry-Academia-Research Organizations Including Hyundai Motor Participate
Challenge to Localize 6.5% Silicon Wide Electrical Steel
Securing Key Materials to Enhance Electric Vehicle Motor Efficiency

POSCO is embarking on the event of high-efficiency electrical metal sheets that may contribute to bettering electrical automobile power effectivity (EV gas effectivity).

POSCO officers held a kickoff assembly for collaboration on next-generation electrical metal sheet expertise with representatives from 10 industry-academic-research establishments, together with Hyundai Motor Company, on the Pohang Institute of Industrial Science and Technology (RIST) on the eleventh, and are posing for a commemorative picture.

POSCO introduced on June 11 that it held a kickoff assembly on the Pohang Institute of Industrial Science and Technology (RIST) for the challenge titled “Development of 6.5% Silicon Wide Electrical Steel Sheet and High-Efficiency Core and Drive Motor Manufacturing Technologies for Electric Vehicles,” marking the beginning of joint analysis and growth.

This challenge is a part of the “Specialized Steel Sheet Technology Development Project for Core Automotive Components,” supported by the Ministry of Trade, Industry and Energy and the Korea Evaluation Institute of Industrial Technology (KEIT). POSCO is main the challenge, with Hyundai Motor Company, SL, Polfair Electric, in addition to analysis institutes and universities, making up a complete of 10 collaborating organizations.

The core of the analysis is to safe manufacturing expertise for broad electrical metal sheets containing 6.5% silicon, a key materials for high-efficiency electrical motors, and to confirm the impact on improved power effectivity by making use of this materials to electrical automobile drive motors.

Electrical metal with larger silicon content material can cut back energy loss (iron loss) that happens in the course of the high-speed rotation of motors, thereby growing effectivity. However, because the silicon content material will increase, the fabric turns into extra brittle, making it extra inclined to breakage and making the manufacturing and processing of large-area sheets tougher.

The collaborating organizations signed a memorandum of understanding (MOU) on the identical day and agreed to conduct analysis by linking the complete course of from materials growth to core fabrication and drive motor manufacturing.

Jo Myungjong, Head of the Future Steel Research Institute at POSCO, acknowledged, “We will focus our capabilities on developing advanced materials and component technologies that improve energy efficiency and strengthen collaboration among industry, academia, and research institutes.”

Through this challenge, POSCO goals to safe competitiveness in high-efficiency electrical metal expertise and to strengthen the worth chain competitiveness of the home metal and automotive industries.
