Electric motor efficiency is improved by using thinner sheets of electrical steels. This is important to meet the needs of hybrid/electric vehicles. But more laminations need to be stamped from this thinner metal to get to the same stator height. An article from steelmaker voestalpine says that at least 60 additional high-precision stamping lines/presses will be needed by 2025 for production of 25 million drive motors with a lamination thickness of 0.25 mm rather than the current 0.35 mm. Not highlighted in the article is the likelihood of a greater cost per ton to produce this value added product at a thinner gauge.
