    • The invention relates to a rotodynamic machine for conveying a fluid, like a turbo-machine (2) or a centrifugal pump, with at least one drive and bearing device (1) in the form of an electric motor with a stator and a magnetic-bearing rotor (4a), in which the windings (15, 16) generating the torque and the magnetic bearing force are arranged together in the stator, the rotor (4a) forms a section of the shaft (4) of the turbo-machine (2) and there is a control device (7) controlling one of the two windings, in such a way that a magnetic bearing force acting on the rotor (4a) can be generated by the first winding (16) in order contactlessly to hold the shaft (4) radially and a torque acting on the rotor (4a) can be generated by the second winding (15).
    • 本发明涉及一种转子动力机器用于输送流体作为涡轮机(2)或一离心泵具有至少一个驱动器和轴承装置(1),其被设计为电动机的定子和一个带磁悬浮转子(4a)的 其中,所述转矩和磁轴承的力实现绕组(15,16)共同在所述定子和所述转子(4a)的布置形成所述轴的一部分(4)涡轮机(2),并且其中,所述两个绕组(的 设置15,16)-addressing控制装置(7),使得(与第一线圈16)中的(在转子4a)的作用磁力支承力可产生在径向方向上以保持所述轴(4)不接触,并且 到转子上的第二绕组(15)(4a)的作用扭矩产生。
