点があった。Generally, in a normally conducting rotating electric machine, an armature winding is attached to an armature core that is a magnetic material to form an armature. In a superelectric rotating electric machine, the armature winding does not need to be supported by a magnetic iron core, but the armature winding must be supported in some way. Conventionally, the method of holding the armature windings is to combine and arrange the armature windings on a cylindrical assembly jig, and then insert a spacer between the windings of adjacent straight parts to hold the entire armature winding together. I created a #t1a child winding in a way that would bind it. This armature winding was supported by a holder made of a non-magnetic material and attached to a stator frame to form an armature. However, this armature structure has a disadvantage in that the cooling effect of the armature windings due to the circulation of the cooling medium is poor, and as a result, the permissible temperature of the insulating material is limited, so that the %Iso size must be increased.

To achieve this objective, the armature structure is made as follows. In other words, in an armature in which the armature winding is supported by an annular insulating holder fixed to both axial ends of the stator frame of a superconducting rotating machine, the linear portion of the armature winding is A cooling duct was formed on the side surface or on the surface of the paper on the outer diameter side of the armature winding via a plate-shaped duct piece made of non-magnetic metal and extending in the axial direction, and cooling was performed by the cooling duct.

, 232 are embedded in the holding body 2, and the ζ electric machine pre-winding s4 is incorporated therein. This armature is supported on the inner periphery of the stator frame by two parts of the holder. Both winding ends of the armature winding 4 are covered with end covers 6.61 having flow holes 6a, 6a', and the inner circumferential surface of the armature is sealed with cannes. During operation, the structure is such that the cooling medium flows in the direction of the arrow. Here, the assembly structure of the holder 2 and the armature winding 4 mentioned above will be explained. The structures of type 3s in Figures 2 and 3, which show the A-A cross section in Figure 1, all use non-magnetic thin plates to configure the cooling duct for flowing the cooling medium, and have a turret winding inside. A space is provided to store #4 (straight section). This duct piece is made of a material with good thermal conductivity, such as non-magnetic stainless steel, to ensure effective cooling. Figure 2 shows an example in which cooling ducts) Bl and B2 are provided on both sides of the armature winding 4 with the duct pieces 31, 32, and 33 aimed at each other, and 7 is an electric machine pre-winding [4 is held down and fixed. It is a wedge. In Figure 3, duct pieces 131, 132 *133 are combined to form a cooling duct on both sides and bottom of the armature winding) 01.02.
An example with 03 installed, Figure 4 shows duct piece 2311232
This is an example in which the cooling duct D is provided only on the bottom surface. The selection of these structures is determined based on the loss 1) that occurs in the armature winding, the thermal characteristics of the cooling medium, the flow rate, etc., so that the temperature of the insulator is within a permissible value.
