Abstract: Rotary synchronous machine includes a stator and a rotor. The stator includes a magnetic field core and an armature core magnetically separated from each other. The rotor includes a plurality of magnetic substance segments which are magnetically separated from each other in a direction of rotation but are magnetically coupled with both of the magnetic field core and armature core. The rotor and magnetic field core are arranged to cause an axial thrust to the rotor depending on the intensity of electric currents passed through filed windings. Namely, the rotor and magnetic field core are arranged in such a manner that magnetic attraction (magnetic coupling) occurs between the rotor and the magnetic field core in a same direction as a rotational axis or at a predetermined non-normal angle relative to the rotational axis.
