PROBLEM TO BE SOLVED: To efficiently cool a superconducting motor, which is used as a driving source for an electric automobile, with a simple structure. SOLUTION: The superconductive motor 11 is surroundedly stored inside a tank 20 for reservoiring liquid hydrogen 25. The superconductive motor 11 is cooled with the liquid hydrogen 25. A rotational drive shaft 13 and an electric wire 29, which are drawn out from a housing of the superconductive motor 11 to the outside, are drawn out to the outside of the tank 20 through the inside of one shielded pipe 26 extended to a taking-out port 27 provided on the outer wall of the tank 20 continuously to the surrounding space 28 of the tank 20. The superconductive motor 11 is installed at a position apart from the taking-out port 27 in the tank 20. Thus, the shielded pipe 26 is made longer. COPYRIGHT: (C)2005,JPO&NCIPI |
