World's Fastest Motor
A new motor developed by researchers at ETH Zurich's Department of Power Electronics and marketed by the Swiss company, Celeroton, can spin in excess of 1 million revolutions per minute.
As a comparison, collapsed stars spin at 60,000 rpms, a blender at about 30,000 and high performance engines at around 10,000 rpms.
The matchbook-sized motor has a titatnium shell, ultra-thin wiring and a trade secret iron formulated cylinder. The need for smaller electronic devices requires smaller holes, which means smaller, faster, more efficient drills.
