JPH11332025A - Levitated running electric rolling stock - Google Patents

Abstract

PROBLEM TO BE SOLVED: To permit the line of magnetic flux of a magnet to play the role of gear for running on an aluminum plate and thereby allow an electric rolling stock to run with a magnet. SOLUTION: A strong magnet 1 and a conductor 4 are used. The magnet is attached to a motor shaft so as to rotate, while the conductor 4 is laid between rails. Since a cylindrical magnet formed of N and S poles arranged in the shape of a sector so as to equally divide a circle is rotated at high speed, electric field is generated between aluminum of conductor 4, and magnet and a current is generated on the aluminum plate 4. This current repulses for the magnetic flux lines of the magnet, and thereby an electric rolling stock is levitated. In addition, the lines of magnetic flux on the gear generated, depending on arrangement of magnet results in a propelling force of the electric rolling stock.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The technical field according to the present invention belongs to the technical field of electric trains such as electric trains and linear motor cars.

[0002]

2. Description of the Related Art A conventional train travels on a railway by rotating wheels on a motor as a driving force.

Further, a linear motor car using a superconducting magnet must cool the coil to near zero degrees, and requires a very large-scale cooling device. Moreover,
Construction costs are high because the tracks need to be filled with coils.

[0004]

In the conventional train technology, large-scale and expensive equipment such as a linear motor car is required if the train is to be raised and operated.

[0005] In addition, if the train is operated without being lifted, the speed is naturally limited. This is because friction occurs because the wheels of the train are rotated by the motor on the rails.

[Means for Solving the Problems]

In the apparatus according to the present invention, unlike a conventional train such as a Shinkansen train which can only reach a certain speed due to the limit due to friction between the rail and the wheels, the train is operated by floating from the rail. However, at this time, the train is levitated by a simple principle without using expensive superconducting magnets.

FIG. 1 shows a basic schematic diagram of a train according to the present invention. That is, according to the present invention, a simple structure is provided in which a magnet is attached to a conventional train, and then aluminum or the like is laid on the center of the track.

FIG. 2 shows the rotor portion (magnet) of FIG.
1 shows a cross section of

The magnet shown in FIG. 2 uses a rare earth magnet having a strong magnetic force such as neodymium.

Referring to FIG. 1, first, a magnet mounted on the axis of the motor rotates together with the rotation of the motor. When spinning at low speed, the train does not rise yet. This is the same phenomenon as a linear motor car.

When the motor rotates beyond a certain number of revolutions, as shown in FIG. 2, a magnetic field generated by N-pole and S-pole magnets alternately arranged in a fan shape in a circle causes an electric current in an aluminum plate which is a conductor. .

The electric field induced in the aluminum plate produces a current in the same direction as the magnetic field.

The current of the aluminum plate repels the magnetic flux generated from the magnet.

The train rises due to this repulsion.

Next, the principle of propulsion will be described.

As shown in FIG. 2, magnetic flux lines are generated on the magnet.

When the magnetic flux lines rotate at high speed, a current is generated in the aluminum plate as described above, and a floating force acts on the magnet along the arc of the magnet approaching the electrode of the aluminum plate.

For example, the magnetic flux lines of the magnet travel on the aluminum plate as a gear.

Therefore, the relationship between the magnet and the traveling direction of the train is as shown in FIG.
