发明名称 BALANCE CORRECTION OF MAGNETIC BEARING
摘要 PURPOSE:To eliminate unbalance caused through shifting of the center of magnetic field by applying magnetic field onto a portion of a magnetic metal ring. CONSTITUTION:An electric magnet 10 is arranged near to a magnetic metal ring 2 then magnetic field 9 higher than the saturation field of said ring 2 is provided to partially magnetize said ring 2 thus to produce uneven field or shifted field of remanence on the end face 2a even after removal of field 9 and to vary the center of magnetic field of rotary member 1 at the position to be balanced magnetically. Since the rotary member 1 journaled through magnetic bearing will rotate around the center of magnetic field, unbalance can be corrected by varying the center of magnetic field or the center of rotation.
