Title:
超電導ロータ及び超電導モータ
Document Type and Number:
Japanese Patent JP6883210
Kind Code:
B2
Abstract:
To provide a superconducting rotor which reduces electric resistance as much as possible.SOLUTION: A superconducting step portion 52b of a superconducting rotor bar 52 has a plurality of stages of superconducting stage faces arranged so that a radial position may face to a radial outside of a rotor core 3 and gradually change along an axial direction of the rotor core 3. In addition, the superconducting stage faces of the same stage of the superconducting step portions 52b of the plurality of superconducting rotor bars 52 are arranged along a circumferential direction of the rotor core 3. A superconducting end ring 62 has a plurality of superconducting end ring winding portions formed in a stepwise manner and annularly by winding a superconducting tape line material around the superconducting stage face at the same stage arranged along the circumferential direction of the rotor core 3 and the superconducting stage face at a stage adjoining to the superconducting stage face of the same stage, and is composed by disposing the plurality of superconducting end ring winding portions along the axial direction of the rotor core 3.SELECTED DRAWING: Figure 5
