    • A magnetic bearing system includes a rotor shaft 1, stationary electromagnetic pole, a radial displacement sensor 5 for detecting the position of the rotor shaft 1 with respect to the electromagnetic polarity, and a control circuit 220 which supplies a control current in accordance with an output from the radial displacement sensor 5. A permanent magnet 20 is disposed in the magnetic bearing so as to constitute a portion of a magnetic member 10 which forms a magnetic circuit between the rotor shaft 1 and the electromagnetic pole. The position where a balance exists between an attraction force developed in the permanent magnet 20 and static force, which acts on the rotor shaft 1 when no load is imposed on the rotor shaft 1, is set as a target position for the rotor shaft 1.
    • 磁轴承系统包括转子轴1,固定电磁极,用于检测转子轴1相对于电磁极性的位置的径向位移传感器5以及根据输出提供控制电流的控制电路220 永磁体20设置在磁性轴承中,以构成在转子轴1和电磁极之间形成磁路的磁性部件10的一部分。 作为转子轴1的目标位置,在永磁体20中产生的吸引力与作用在转子轴1上的静力之间产生平衡的位置被设定为转子轴1的目标位置。
