UK Engineers Develop Record-Efficiency Electric Motor Using Amorphous Steel

publication · 2026-03-27

A British motor manufacturer has created an electric motor achieving 98.2% efficiency, setting a new record. The design utilizes amorphous steel, also known as metallic glass, which has glass-like properties due to its irregular atomic structure. This advancement highlights the superior efficiency of electric motors compared to internal combustion engines, which typically operate at 25-35% efficiency. The development underscores progress in electric vehicle technology, contributing to more sustainable transportation.

Key facts

  • An electric motor with 98.2% efficiency has been developed in the UK
  • The motor uses amorphous steel, or metallic glass, for its construction
  • Internal combustion engines have efficiencies between 25% and 35%
  • Electric motors generally convert 85% to 95% of energy into usable motion
  • The new motor loses only 1.8% of input energy as waste
