<p><P>PROBLEM TO BE SOLVED: To provide a superconduction device which is advantageous in improving durability of a superconducting coil. <P>SOLUTION: The superconduction device includes a drive part 300 for driving, an operation part 400 for operating drive amount of the drive part 300, a superconducting motor 2 which is arranged between the operation part 400 and the drive part 300 and is equipped with a superconducting coil formed of superconducting material, a refrigerator 30 for cooling the superconducting coil of the superconducting motor 2, and a control part 500 for controlling the refrigerator 30. When an operation amount of the operation part 400 increases or an amount of current supplied to the superconducting coil of the superconducting motor 2 increases, the control part 500 performs operation to enhance refrigeration output of the refrigerator 30 in preference to a temperature signal of a temperature sensor that measures the temperature of the superconducting coil. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
