Title:
高Tc超伝導材料を使用して回転軸を支承する磁気軸受
Document Type and Number:
Japanese Patent JP3840182
Kind Code:
B2
Abstract:
The invention relates to a magnetic bearing (2) for magnetically suspending a rotating shaft (3) within a stator. Said magnetic bearing comprises a first bearing element (5) rigidly linked with the shaft which is enclosed by a second bearing element (13) pertaining to the stator, thereby defining a bearing clearance (12). A system of magnets (7) of the first bearing element with permanent magnet elements (8i) and a cooled superconducting system (14) of the second bearing element with high Tc superconducting material are commonly enclosed by at least one insulating compartment (V1, V2). An additional compartment (25) which is separate from said insulating compartment encloses the bearing clearance (12) and partial compartments (25a, 25b; 26a, 26b) that radially extend on lateral sides of the superconducting system and of the system of magnets up to the shaft (3) and are sealed from the shaft.
