Japanese Patent JP2586067
Kind Code:
B2
Abstract:
PURPOSE:To improve reliability by spirally winding spiral insulation on a superconducting wire for a superconducting field coil and forming cooling paths into air gaps among the spiral insulation. CONSTITUTION:A rotor for a superconducting rotary electric machine is composed of a coil mounting shaft 2 to which a slot 18 and a helium flowing hole 22 are shaped, superconducting field coils 25, lower and upper insulating materials 28-29, an insulating material 30 in the slot, and a cylindrical body 31 fitted on the outer circumferential side of said coil mounting shaft 2. Said field coil 25 is formed by winding plural rows and plural layers of superconducting wires 25a. The conductor 25a has spiral insulation 26 wound spirally, and cooling paths 27 are shaped into air gaps among the spiral insulation 26. A refrigerant is made to flow through various cooling paths 28a-28c, 29a-29c, 30a, 2a communicated with said helium flowing hole 22, thus cooling said coils 25.
