ABSTRACT:
Rotating machine with a rotor (44) with an inductor of an electrical radial field machine (48) arranged on the rotor (44), which radial field machine is designed for absorption of the radial bearing forces acting on the rotor, and with an inductor of an axial field machine (46) arranged on the rotor (44), which axial field machine is designed for absorption of the axial bearing forces acting on the rotor. For normal force control, means for field control with the aid of current influencing are provided in the stators of the two electrical machines, which for their part are each subdivided into four quadrants with their own regulating units. The two electrical machines (46, 48) are of multipole design, there being at least two poles per winding quadrant. The axial field machine (46) is provided with three controllers for the stabilization of three degrees of freedom and the radial field machine (48) is provided with two controllers for the stabilization of two degrees of freedom.
