MAGNETIC BEARING WHEEL FOR AN ARTIFICIAL SATELLITE

摘要

A magnetic bearing arrangement for rotor for controlling the attitude of an artificial satellite wherein the rotor has a rotating speed and an axis of rotation which are adjusted in accordance with a change in the attitude of the satellite. The arrangement includes a stator defined by at least three segments, and each stator segment is provided with a permanent magnet to eliminate the necessity of any electromagnet for controlling radial rotor displacement and any sensor for detecting such radial displacement. The apparatus is free from any eddy currents that may cause great resistance to rotation.
