The main part is composed of a magnetically anisotropic conductive material 6 made of a conductive material 5.

制御することができる。With the above configuration, a rotor can be obtained in which the magnetic permeability μr in the radial direction is larger than the magnetic permeability μe in the circumferential direction (μ4>μe) and the resistivity ρχ in the axial direction is small. When this induction motor is driven, due to the large magnetic permeability μr with little variation in the radial direction, magnetic coupling with little magnetic fluctuation is obtained with the stator, and driving with little vibration and noise can be achieved. , and since the winding was omitted from the rotor,
It is possible to achieve reduction in size and weight. Furthermore, magnetic permeability and resistivity can be controlled depending on the space ratio of the magnetic material and the conductive material.

向上を図ることができる。As a method for producing this magnetically anisotropic conductive material, for example, the methods shown in FIGS. 8(a) and (U) and FIGS. 9(a) and (b) have been proposed. 8(a) and 8(b) show a composite material 13 composed of a magnetic material 11 such as a steel wire, a saw coated on the outer periphery of the magnetic material 11, and a conductive material 12 such as aluminum. '), (TJ) is the composite material 13
The gap between the composite materials 13, which expands according to the distance from the center point O, is filled with powder 14 of a conductive material such as aluminum, and by heating and pressurizing them, an annular shape with an inner diameter r and an outer diameter R is formed. This shows that a magnetically anisotropic conductive material is manufactured (actually, the materials shown in FIGS. 9(a) and 9([7]) will be arranged in multiple layers, but they are omitted for illustration purposes). According to this manufacturing method of magnetically anisotropic conductive material, compared to a manufacturing method in which a conductive material is cast between a composite material consisting of a magnetic material and a conductive material, manufacturing is easier and the space factor of the magnetic material is lower. You can improve your performance.

仕上げると磁気磁気異方性導電材料が得られる。FIG. 4 shows a cold isostatic pressurizing device used in the present invention, in which the upper M14 and lower M19 have high-pressure oil inlets 14a and 19a, and the upper and lower M14.19 form a cylindrical space. In the above-described apparatus, which is constituted by a cylindrical body 18 and in which a high-pressure liquid 15 of castor oil is present in the cylindrical space, the above-described composite materials 13 are arranged in an array of, for example, 182 pieces per stage, These are stacked in multiple stages to a predetermined height. After putting it in a rubber bag 17 and sealing it with a rubber stopper 16, it is put into a cylindrical space of a cold isostatic pressurizing device, and the high-pressure oil inlets 14a and 19a are opened by a high-pressure generating pump (not shown). High pressure liquid through 1
Rubber bag 1 sealed by sending 5 into a cylindrical space
The whole of 7 is pressurized in a cold state at a pressure of 1500 kgz'cm2 or more. This allows the laminated composite materials to be uniformly compressed and integrated. The composite material 13 which has been reduced in pressure and integrated with the processed layer is taken out and finished into a predetermined shape and size to obtain a magnetomagnetic anisotropic conductive material.

Although the redundant explanation will be omitted since it has already been shown, the difference is that the corners of the rectangle have curved surfaces. The curvature of this curved surface may be set to such an extent that when the composite materials 13 arranged in an array are laminated in multiple stages and cold pressurized, no gaps are created between the magnetic materials 11 due to plastic deformation of each layer.

By this method, it is possible to improve the workability of aligning and arranging the composite materials 13 and laminating them in multiple stages. Of course,
Workability can be further improved by dividing the case 30 into a plurality of parts in the circumferential direction. In this case, the end of the composite material has a shape that smoothly aligns with the engaging part 30a of the case 30, and since both ends of the magnetic material 11 are exposed on both sides of the case 30, the magnetic permeability in the radial direction does not give a description.
