UK Engineers Develop Record-Efficiency Electric Motor Using Amorphous Steel
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.
