More efficient motors are surging ahead

Motors are driving the zero-emissions race to electrification, but what if we could make them smaller and more efficient? David Calley, who spoke to Lexicon at CES 2023 in Las Vegas, is one entrepreneur working on the issue. His company, Arizona-based Elemental Motors, is digging into more efficient designs that could offer five or more times the torque density than comparably-sized motors. It could power robots, industrial applications and eVTOLs, paving the way for improvements in mobility.
