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.

Abstract: Linear motor includes a moving member tapered relative to a traveling direction to provide a surface slanted relative to the traveling direction toward one end of the moving member, a stator having a surface that is opposed to the slanted surface of the first member and slanted relative to the traveling direction at an angle corresponding to the slanted angle of the slanted surface of the moving member, a field pole producing section for producing field poles on the slanted surface of the moving member, and an armature section provided on the stator and including armature windings so as to produce electromagnetic poles corresponding to electric currents passed through the armature windings. Thus, the moving member is caused to move relative to the stator, by exciting the armature windings to produce a linearly moving magnetic field.
