PROBLEM TO BE SOLVED: To provide a bearingless rotating machine which enables it to achieve size reduction of coil ends and simplification of a power amplifier at the same time. SOLUTION: In a bearingless rotating machine, whose rotor is levitated magnetically by superposing a control magnetic field of n (=m±2) poles synchronously with a rotating driving magnetic field of m poles, giving torque to the rotor, and increasing or decreasing the control magnetic field of n poles from the displacement of the rotor detected by a rotor displacement detecting means, respective one sides of a plurality of coils on a stator are wound in the inside slots of the stator, and the other sides are wound on the outside part of the stator. Each coil is independent, and two coils are arranged per slot. One of the coils is used for generating an m-pole magnetic field, and the other coil is used as one for generating an n-pole magnetic field. |
