Claims (1)

Выполненный симметрично по вращению магнитный подшипниковый блок, содержащий ротор с двумя кольцами из постоянного магнита и статор с входящим в зазор между кольцами из постоянного магнита ротора демпфирующим диском. Для улучшения радиальной жесткости этого блока предлагается, чтобы на валу было закреплено дополнительное кольцо из постоянного магнита, образующее с соседним кольцом из постоянного магнита зазор, и чтобы в этот зазор входил закрепленный на статоре кольцевой диск, несущий на себе в зоне вращающихся колец из постоянного магнита ротора намагниченное в осевом направлении кольцо из постоянного магнита статора.A magnetic bearing block made symmetrically in rotation, comprising a rotor with two rings of a permanent magnet and a stator with a damping disk entering the gap between the rings of the permanent magnet of the rotor. To improve the radial stiffness of this block, it is proposed that an additional permanent magnet ring be fixed to the shaft, forming a gap with the adjacent permanent magnet ring, and that this gap should include an annular disk mounted on the stator, bearing on it in the area of the rotating rings of the permanent magnet axial magnetization of the rotor of the permanent magnet ring of the stator.
