The surface of the heat-insulating vacuum vessel 16 facing the disc-shaped armature 12 is plated with a material having low emissivity (gold, copper, etc.). In addition, in view of the fact that the superconducting coils 13a facing each other with the annular armature 12 in between are attracted to each other by strong magnetic force, the gap between the liquid helium container 14 and the heat-insulating vacuum container 16 is wide enough to allow enough space when assembled. The position where the magnetic force and the force due to the deflection of the heat insulating support body 17 are balanced during excitation is set correctly.

Each superconducting coil 13 is filled with liquid helium.
A is cooled to an absolute temperature of 4.2 degrees and becomes superconducting. At this time, the liquid helium container I4 is fixed to the heat insulating vacuum container 16 via a heat insulating support 17 in order to prevent heat from entering the liquid helium container RH4. Since the heat insulating support 17 thus supports the radiation shield 15 cooled with liquid nitrogen, the degree of heat infiltration into the liquid helium container 14 is further significantly reduced.

出力を取り出すことが出来る。When each superconducting coil 13a is excited, lines of magnetic force are generated between adjacent superconducting coils 13a, as shown by arrows in FIG. Therefore, each superconducting coil 13a
Since the magnetic field is formed only in a narrow periphery of the motor housing, the magnetic field hardly reaches the outside of the motor housing. At this time, when a predetermined current is applied to the disc-shaped armature 12 via the brush 18, the disc-shaped armature 12 obtains rotational force by the Lorentz force and rotates, so that the output of the motor can be extracted from the shirt I-11. I can do it.
