Posco, Hyundai team on high-silicon electrical steel for EV motors
Posco has opened a joint development effort with Hyundai Motor and other partners aimed at a high-silicon electrical steel used as a precursor for stator and rotor production, according to electrive. The material is intended to yield more efficient electric motors.
The work is built around electrical steel carrying a silicon content of 6.5%, electrive reported. Lifting the silicon share cuts iron losses in a motor's magnetic core, though it also leaves the metal more brittle, turning the rolling of thin, large-format sheets into a manufacturing hurdle, according to electrive.
Ten partners signed a Memorandum of Understanding to set the collaboration in place, electrive reported. Funding comes from South Korea's Ministry of Trade, Industry and Energy (MOTIE), with the Korea Evaluation Institute of Industrial Technology (KEIT) handling coordination, according to electrive.
Cho Myung-jong, Head of the Future Steel R&D Center at Posco, said the effort brings the steel and future mobility industries together on electrification, according to electrive.
The steel project follows a separate battery-materials deal. Posco struck a multi-year contract with SK On earlier in the year for up to 25,000 tonnes of lithium concentrate sourced from Argentina, destined for electric vehicle batteries and stationary storage, electrive reported.
