PROBLEM TO BE SOLVED: To provide a bearingless rotating machine which can suppress the axial deflective vibration at low cost, without requiring a controller, a sensor, an inverter, etc. SOLUTION: This bearingless rotating machine, which is equipped with a stator 1 where first winding for generation of rotating torque is wound and a rotor 4 which is arranged concentrically opposite to the stator 1 via an air gap and where rotating torque is generated by the magnetic mutual action between the stator 1 and the rotor 4 when the first winding is supplied with power for generation of rotating torque and the rotor 4 rotates thereby, is equipped with second winding which detects the change of the radial components of the magnetic flux caused by the rotation of the stator 1 with the center axis of the rotor 4 displaced from the center axis of the stator 1. This second winding is connected to an AC/DC converter 6, and this AC/DC converter 6 is connected to a DC circuit 7. COPYRIGHT: (C)2005,JPO&NCIPI
