PROBLEM TO BE SOLVED: To provide a centrifugal separator having a rotor rotating in non- contact and non-friction state in single or plural of super conductive magnet bearings arranged at certain magnetical intervals during centrifugal separation. SOLUTION: A rotor device (1) has one or more permanent magnet structures (6, 7, 8, 9; 11, 12, 13, 14). The permanent magnet structures are arranged at prescribed intervals adjacently to at least a passive super conductive magnet stators (19, 20). The permanent magnet structures and the magnet stators form at least one magnet bearing.
