Demonstration and test of low-loss, high reliability, high speed, bearing-relief generators

Power dense electrical generators are required to operate at high rotational speeds. Conventional, contact bearing technology is mature but limits generator efficiency, maximum rotational speeds and reliability. This project will demonstrate a new class of bearing-relief generators where radial forces are controlled electromagnetically taking loads off the bearings and additionally suppressing any rotor vibrations.
