[0002]

2. Description of the Related Art Conventionally, as a power generating device for obtaining power from electric energy, a rotating electromagnet is rotated by a mutual attractive force of an annular fixed electromagnet and a rotating electromagnet supported at the center thereof, and the rotating force is taken out as power. There is a so-called electric motor.

[0003] However, in such a conventional motor, both the fixed side and the rotating side are electromagnets, and use only electric energy. For this reason, the output does not increase in spite of using power, and improvement in this point has been desired.

[0004]

And in addition to intermittent input to each electromagnet,
Accordingly, it is an object of the present invention to provide a power generating device capable of eliminating useless input.

[0006]

Next, the operation of the present invention will be described. In the present invention, the magnetic force of the permanent magnet is generated by making the rotor, which is a magnetic material, magnetically permeable. Then, in a state where current is not supplied to any of the annularly arranged electromagnets, the electromagnet whose protruding portion of the rotor is approaching is in the magnetic field of the permanent magnet as a simple magnetic body.

Therefore, when an electric current is supplied to the electromagnet next to the electromagnet to which the protruding portion of the rotor approaches , the magnetic flux from the permanent magnet is generated.
Is the range that is almost linearly connected to the energized electromagnet instantaneously.
Converged within the enclosure to form a magnetic domain. As a result, the protrusion of the rotor is strongly attracted to the electromagnet, and the rotor rotates. At this time, the direction of rotation of the converged magnetic flux of the rotor protrusion is
There is a blank area of speed per hour behind and behind,
Between the non-excited electromagnet and rotor adjacent to the
Does not interact. In other words, the rotor
Reduces the attractive force in the direction that hinders rotation by a non-excited electromagnet.
I will not receive it. When the rotor is further rotated, the width of the magnetic domain portion of the protrusion of the rotor gradually increases, and the attraction force further increases.

The input of the electromagnet is temporarily stopped when the rotor rotates by a small angle, for example, 5 degrees, and when the rotor further rotates and rotates more than 5 degrees, for example, 10 degrees, the input of the electromagnet is stopped again. After inputting and continuing inputting for another 5 rotations, stop inputting again. And then 10
Input the next electromagnet when rotated.

By repeating this operation, the rotor rotates. Then, the rotation is performed smoothly, and a strong rotating force can be generated with a small amount of electric power by a strong attraction effect by the magnetic force of the permanent magnet and the magnetic force of the electromagnet. Further, since the energization of each electromagnet is performed intermittently, useless input can be omitted. Then, the rotational force of the rotor rotating as described above is taken out from the power shaft as an output.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic explanatory view of an embodiment of the present invention,
FIG. 2 is a partially cutaway front view, and FIG.
4 to 8 are operation explanatory diagrams.

In the drawing, reference numerals 1, 1,... Denote electromagnets, which are arranged in a ring on the same circumference. The electromagnet 1
May be plural, and in the present embodiment, the number is 12, but the number is not limited to this. Reference numeral 2 denotes a rotor made of a magnetic material disposed in the electromagnets 1, 1,... Further, the rotor 2 is provided with a protruding portion 3 whose tip is inclined in the rotation direction. In this embodiment, six protrusions 3, 3,... Are provided at equal intervals.
3a is an end of the protruding portion 3.

Reference numeral 4 denotes a permanent magnet attached to the base of the protrusion 3 of the rotor 2. In this embodiment, the permanent magnets 4, 4,... Attached to the six protrusions 3, 3,.
Is such that the outer pole is a different pole.

Reference numeral 5 denotes a power shaft provided at the center of the rotor 2. Reference numeral 6 denotes a holding frame for holding the electromagnet 1 and the rotor 2. Reference numerals 7, 7 denote the electromagnets 1, 1,.
A current switching circuit for supplying a current at a predetermined timing according to the rotation angle of the rotor 2;
Are connected.

Next, the operation of the embodiment will be described. 4 to 8 show the action of the rotor in response to the input to the electromagnets 1, 1,..., And FIG. 4 shows the state in which the end 3a of the protrusion 3 of the rotor 2 approaches the electromagnet 1a. It is a state diagram. When input to the electromagnet 1a in this state, permanent magnet
The magnetic flux 4a of the stone 4 makes the electromagnet 1a and the permanent magnet 4 almost straight.
It is converged within the range where the connection is made, and the width is reduced. Shown in FIG.
At this time, it converged in the rotor projection 3
A blank area of the magnetic flux is formed behind the magnetic flux 4a in the rotation direction.
To rotate the electromagnet 1a, which is already non-excited.
The rotor projection 3 is not sucked and hinders the rotation of the rotor.
No.

As the rotor 2 further approaches, the magnetic field 4a converged on the electromagnet 1a gradually widens. As a result, the rotor 2 is strongly attracted to the electromagnet 1a and rotates.

When the rotor 2 further rotates and rotates by a small angle, for example, 5 degrees as shown in FIG. 5, the input of the electromagnet 1a is temporarily stopped. Then, as shown in FIG. 6, the rotor 2 rotates by, for example, 10 degrees, and when the end 3a of the protrusion 3 approaches the end of the electromagnet 1a, the input to the electromagnet 1a is started again. Then, the input is continued while the rotor 2 rotates five degrees, and the input is stopped when the end 3a of the protruding portion 3 of the rotor 2 slightly exceeds the electromagnet 1a as shown in FIG. Then, when the rotor 2 rotates 10 degrees and the end 3a of the protruding portion 3 approaches the adjacent electromagnet 1b as shown in FIG. 8, the input is made to the electromagnet 1b. In this embodiment, the rotor 2 is rotated by repeating these operations.

Also, during the above operation, the rotor 2 rotates by inertia while the input to the electromagnet 1 is stopped, that is, the section of 10 degrees in the above example. Also, while inputting to one electromagnet, the magnetic field 4a is converged on the electromagnet. Therefore, even if the rear side in the rotation direction of the protruding portion 3 of the rotor 2 is located at the position of another electromagnet, it is located at that portion. Since there is no line of magnetic force, it is no longer a magnet, but becomes a magnetically blank area, and is merely a magnetic substance, and does not act as a resistance to rotation of the rotor 2.

The present invention has the above-described structure and operation,

In addition, since each electromagnet is intermittently input, useless input can be omitted.
