As a result, the coil is energized to generate a dynamic magnetic field in the coil, and a repulsive force is generated between the coil and the ring.
- the magnetic flux generated by the coil passes through the inside of the closed circuit formed by the ring at a high density by using the pole pole as a magnetic path, and as a result, the inside of the ring A large eddy current flows, resulting in a large repulsion. Also, even if the distance between the coil and the ring is large, the magnetic pole columns of the magnetic material serve as magnetic paths to transmit the magnetic flux, so that the reduction of the repulsive force is small.

- Dynamic magnetic field A magnetic pole 1 made of a magnetic material penetrates a coil 2 for generating a magnetic field and a ring 3 made of a non-magnetic metal material.
- the ring 3 is preferably made of copper, aluminum, or the like, which is desirable for a metal having high electric conductivity.
- the material of the pole column 1 has a high magnetic permeability. Desirably the conductivity.
- a laminate of silicon steel sheets or the like is suitable as a material.
- a thickness approximately equal to the inner diameter of the coil 2 is suitable.
- the magnetic pole column, the coil, and the non-magnetic metal body have the same configuration as that of the conventional technology (temporary non-penetration type), and the configuration shown in claim 1 (temporary penetration type).
- the repulsive force was measured.
- the coil 2 and the magnetic pole 1 are fixed with the end faces of the coil 2 and the magnetic pole 1 aligned to maximize the repulsive force.
- the coil 2 and the magnetic pole 1 were fixed with the shaft projecting about 110 mm in the coil force as shown in FIGS.
- the magnetic pole column 1 used in the experiment is a bundle of iron bars, for simplification of the drawing, it is shown as a single column in the drawings other than FIG.
- a 50 Hz sinusoidal alternating current was applied to the coil, and the repulsive force applied to the non-magnetic metal was measured with a force gauge.
- FIG. Fig. 6 is a graph in which the horizontal axis is the current flowing through the coil, the vertical axis is the repulsive force applied to the non-magnetic metal body, and Fig. 7 is the horizontal axis is the gap length between the coil and the non-magnetic metal body, and the vertical axis is the vertical axis. 6 is a graph showing a repulsive force applied to a non-magnetic metal body.

- B is the repulsion force in the non-penetration method using the aluminum ring as the non-magnetic metal body
- C is the repulsion force in the aluminum disk. It shows the repulsive force of the non-penetrating method used as a magnetic metal body. As shown in FIGS. 6 and 7, although there is a difference depending on the amount of current and the gap length, the repulsive force becomes larger when using the penetration method according to the present invention than when using the non-penetration method.
- the repulsion force can be used effectively with a larger stroke compared to the non-penetration method, in which the reduction in repulsion is small. .
- a disk-shaped ring is used as the non-magnetic metal ring.
- the ring structure is such that an eddy current induced by a dynamic magnetic field can orbit around a magnetic pole made of a magnetic material. If it is a structure, its shape need not necessarily be circular. The same effect can be obtained with a square or elliptical structure. A similar effect can be obtained by a coil-like structure in which both ends are short-circuited so that the eddy current can orbit the magnetic pole column a plurality of times.
- the poles need not be particularly cylindrical, such as prisms and cylinders.
- FIG. 8 shows a perspective view of an example using a ring-shaped magnetic pole.
- the magnetic pole section is formed by bundling a plurality of insulatingly coated iron cylinders, and the magnetic path cross section is finely divided by an insulator, so that the eddy current inside the pole column is reduced. While suppressing generation, the concentration of magnetic flux is dispersed. According to this method, the magnetic pole becomes heated, and a large amount of magnetic flux can pass through the inside of the magnetic pole. It should be noted that it is possible to obtain a repulsive force between the coil and the ring without using this method, that is, even if the magnetic pole column is constituted by only one magnetic column.

- FIG. 9 is a perspective view of the other-stage guiding repulsion device
- FIG. 10 is a perspective cross-sectional view of the other-stage guiding repulsion device.

- FIG. 11 is a perspective view of a position holding type guide repulsion device
- FIG. 12 is a perspective sectional view of the position holding type guide repulsion device.
- the same effect can be obtained by a structure in which the relationship between the ring 3 and the coil 2 is switched, that is, a structure in which two coils are arranged on both side surfaces of the ring and the two coils are fixed to each other. However, in that case, care must be taken so that the currents flowing through the two coils are in phase. Also, if a method similar to that shown in FIGS. 9 and 10 is used, this position holding force can be increased. Further, in the present embodiment, as shown in FIGS. 11 and 12, the fixing between the rings 3 is performed by the fixing shaft 9, but the fixing means shown here is merely an example, and the same applies to other fixing means. The effect can be obtained.
