초록

A magnetic bearing system uses conductive loops which interact with magnets to levitate a rotor and to center it on a rotational axis. The rotor is provided with a plurality of closed loops of electrically conductive material with a finite inductance. Rotation causes the loops to travel along a prescribed circular path which carries them through a series of magnetic fields. In preferred embodiments, each loop is subjected to two magnetic fields simultaneously, and the magnets are positioned where a loop moving on its prescribed path will be equally subje...
