Further, a rotor 2 (a permanent magnet having a length of about 10 mm and a diameter of 5 mm) comprises a bar magnet 3 with its poles on a rotor shaft within a scope of a cylindrical hole having a diameter of 6 mm. Since a line of force of a magnetic field of the permanent magnet is preferably not beyond lower critical magnetic field, the permanent magnet is sealed by a space between the stator and the rotor. Due to a field force (of a field generated in pair with the field of the permanent magnet) in a longitudinal direction of the rotor shaft, a certain level of axial stabilization of the rotor 2 at the edge of the hole of the stator 1 is attained.  The cooling of the super conductive material is carried out by making cooling liquid pass through a pipe 4.
