Title:
Superconductivity rotation electrical machinery stator
Document Type and Number:
Japanese Patent JP6143076
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a stator of a superconduction rotary electric machine capable of suppressing lowering of current characteristic of the superconduction coil while suppressing increase of the number of parts and allowing simplification of assembling work.SOLUTION: The stator of the superconduction rotary electric machine includes a superconduction coil 1 and a stator core 2. A maximum spacing between one end face of a linear section and an inner wall of a slot is set to a first gap, a maximum spacing between another end face of the linear section and the inner wall of the slot is set to a second gap, a maximum spacing between an outer peripheral surface of the linear section and the inner wall of the slot is set to a third gap, and a maximum spacing between an inner peripheral surface of the linear section and the inner wall of the slot is set to a fourth gap. Then, the superconducting coil 1 is arranged so that at least either of the first gaps A1 and A2 and the second gaps B1 and B2 are smaller than the third gaps C1 and C2 and the fourth gaps D1 and D2.
