<P>PROBLEM TO BE SOLVED: To provide a high performance superconducting apparatus which avoids characteristics deterioration caused by heat of permanent magnets serving as component members. <P>SOLUTION: A superconducting motor includes a stator 20 and a rotor 30. The stator 20 includes superconducting coils 10, and has an opening formed at a center part as shown in Figure 2. The rotor 30 is disposed in the opening of the stator 20 and includes permanent magnets 31. The stator 20 includes cooling containers 50, 60 holding the superconducting coils 10 therein. In the cooling containers 50, 60, the heat conductance of the inner periphery side facing the rotor 30 is larger than the heat conductance of the outer periphery side which is opposite to the inner periphery side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
