Matchbook-Sized Motor Sets 1 Million RPM Record [Rpm Record]
Researchers from ETH Zurich's Department of Power Electronics have developed a matchbook-sized motor that can spin faster than any other machine in the world—over 1,000,000 rpm. In order to keep it from falling apart at such high speeds, the researchers employed a titanium shell, ultra-thin copper wire for the windings and a mysterious top-secret iron that is "previously unused for machines." So does this mean we will all be seeing million rpm engines and hard drives soon? Probably not—but products like faster drills may be feasible in the near future thanks to a Swiss company named Celeroton that has been formed to bring products based on the technology to market.
