Therefore, the magnetic flux generated from the rotor also passes through the armature windings, causing electromagnetic force to be generated. In particular, when the field winding is made of a superconducting material, a strong magnetic field causes a strong electromagnetic force to act on the armature winding.

Further, a magnetic shield 2 made of a ferromagnetic material such as iron is formed at the bottom of the iron core teeth 4 to prevent magnetic flux from leaking to the outside of the stator 1. Further, grooves 6 are provided in the core teeth 4 at predetermined intervals in the circumferential direction, and a portion of the armature winding body 5 and a bottom damper 7, which is a vibration absorbing material, are buried in the grooves 6.

The armature winding body 5 also includes a small conductor 9 made of a large number of wires bundled together, a cooling pipe 10 made of a metal material with high electrical resistance such as stainless steel, and a grounding made of a highly insulating non-magnetic material such as mica. It is composed of an insulating material 11, a wedge 12, and the like.

It is buried in. Also, at the boundary between the armature winding body 5 and the teeth 3 and 4, a side damper 8, which is a vibration absorbing material made of a non-magnetic material such as special silicone rubber, is provided similarly to the bottom damper 7. .

、鉄損が増大する。Next, the operation of this embodiment will be explained. By appropriately setting the length (radial length) of the iron core teeth 4,
The flow path of the magnetic flux flowing from the rotor to the stator 1 can be optimized. In other words, when the core teeth 4 extend to the inner diameter of the stator 1, that is, when all the teeth are made of magnetic material, all the magnetic flux from the rotor tends to concentrate on the teeth. As a result, the magnetic flux density near the tips of the teeth significantly exceeds the saturation magnetic flux density, increasing iron loss.

有することが要求される。On the other hand, in a method called an air-gap winding method in which all the teeth are made of non-magnetic material, the magnetic flux flowing from the rotor to the stator 1 is caused by magnetic flux made of ferromagnetic material such as iron. Up to the shield 2, the windings are distributed at approximately equal density within the armature winding body 5 and the teeth, both of which are made of non-magnetic material. Therefore, the conductor 9 inside the armature winding body 5
An electromagnetic force proportional to the product of the magnitude of the current flowing through the armature and the magnetic flux density of this part acts on the armature winding body 5, which provides high mechanical strength to each member constituting the stator. It is required to have the following.

ができる。However, in the method of this embodiment, in which a non-magnetic material such as FRP is used near the tip of the tooth and a ferromagnetic material such as iron is used near the root of the tooth, the armature winding body 5 is A part of the magnetic flux that has passed through the interior now passes through the core teeth 4, which have a higher transmittance, and the electromagnetic force acting on the armature winding body 5 can be reduced. In addition, near the teeth roots, the cross-sectional area through which the magnetic flux passes can be made larger by adjusting the width (circumferential length) of the bottom damper 7 compared to the teeth tips. Therefore, the magnetic flux density in this vicinity does not exceed the saturation magnetic flux density, and iron loss can be suppressed to the same level as when the air-gap armature winding method is used.

低減することができる。In addition, the floor damper 7 has a small elastic modulus, so it is easily deformed, and by absorbing the strain energy of the armature winding body 5 based on the electromagnetic force mentioned above and converting it into heat through internal friction, etc. , the radial vibration of the armature winding body 5 can be damped. Furthermore, since the material of the floor damper 7 is a non-magnetic material, the flow path of the magnetic flux distributed in this vicinity can be optimized. In other words, the thickness of the floor damper 7 (
By changing the width (radial length) and width (circumferential length) and forming an appropriate cross-sectional shape, the magnetic flux distribution near the root of the teeth can be changed. Therefore, part of the magnetic flux that had previously passed through the inside of the armature winding body 5 is made to pass through the inside of the teeth, and the electromagnetic force acting on the armature winding body 5 can be reduced.

While the bottom damper suppresses radial vibration of the armature winding body 5 due to electromagnetic force, the side damper 8 mainly has the effect of suppressing vibration due to circumferential electromagnetic force.

Can be done. Thereby, it is possible to reduce the electromagnetic force acting on the armature winding body 5 while minimizing iron loss due to magnetic flux concentration, and to suppress vibrations based on this electromagnetic force.

FIG. 2 is an enlarged sectional view of the cooling pipe 10, in which an intermediate support plate 13 is provided at the center of the cooling pipe 10. Although the embodiment described above can considerably reduce the electromagnetic force acting on the armature winding body 5, it is still possible to avoid a strong electromagnetic force acting on the armature winding body 5 due to the strong magnetic field caused by the superconducting field winding compared to the conventional machine. I can't do it. Therefore, in order to increase the radial rigidity of the armature winding body 5, the cooling pipe 10 has a cross-sectional structure with an intermediate support plate 13 in the center. With such a cross-sectional structure, firstly, the cross-sectional area that supports the vertical compressive force of the cooling pipe based on radial electromagnetic force increases, and the compressive stress generated inside the pipe can be kept to a small level. . In addition, regarding the bending of the upper and lower sides of the cooling pipe 10 due to this electromagnetic force, by increasing the support part in the center,
The bending rigidity against radial electromagnetic force increases.

To deal with this, the inner surface of the cooling pipe 10 is made uneven to increase the heat transfer area, thereby improving the heat transfer coefficient and preventing the cooling efficiency from decreasing.
