Title:
SUPERCONDUCTING DYNAMO-ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2016096701
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress heat intrusion from the rotating shaft into the stator, without increasing the gap between the rotor and stator and without lowering the strength of the rotating shaft.SOLUTION: A super-conducting dynamo-electric machine (1) includes a stator 50, a rotor 80, a rotating shaft 70, and a heat insulation member 90. The stator 50 has a coil 60(superconducting coil). The rotor 80 is arranged on the inside of the stator 50 in the radial direction R, rotatable for the stator 50, and has a rotor core 81. The rotating shaft 70 is arranged on the inside of the rotor 80 in the radial direction R, and secured to the rotor 80. The heat insulation member 90 is arranged between the rotating shaft 70 and rotor core 81.SELECTED DRAWING: Figure 2
