DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing the embodiments of the present invention, the principle of the rotating machine of the present invention will be described to facilitate understanding of the present invention.

FIG. 1A is a perspective view showing a basic factor used in the rotating machine of the present invention, and FIG.
FIG. 2 is an exploded perspective view of the basic factor of FIG. FIG. 1C is a front view of FIG.
FIG. 2D is a front view of FIG.

Referring to FIGS. 1A to 1D, the basic factor 10 includes a permanent magnet section 3 and an electromagnet section 4. The permanent magnet portion 3 is formed by sandwiching both sides of a hard magnetic material (permanent magnet) 1 such as a neodymium magnet (Nd-Fe-B) in the magnetization direction with a soft magnetic material 2 such as pure iron.

On the other hand, the electromagnet portion 4 is made of a soft magnetic material such as a U-shaped pure iron having a base 6a and a pair of legs 6b and 6c protruding to one side from both ends of the base 6a. And a coil 7 made of a copper wire wound around a base 6 a of the core 5.

As best shown in FIGS. 1A and 1D, the core 5 of the permanent magnet portion 3 and the electromagnet portion 4
Are formed between both end surfaces of the first and second surfaces, respectively.

FIGS. 2A to 2C show FIGS. 1A to 1D.
3 is a front view for explaining the operation principle of the basic factor 10 shown in FIG.

Referring to FIG. 2A, when the electromagnet section 4 is not energized, the lines of magnetic force of the permanent magnet section 3 simply move around the closed magnetic path of the basic factor 10 as shown by the arrow 8 and the surrounding magnetic field lines move. There is almost no leakage of magnetic flux into the air. Therefore, the joining surfaces D1 and D2 are strongly adsorbed. At this time, the attractive force of the joint surfaces D1 and D2 is formed by the permanent magnet portion 3. This state is called a first state.

Next, as shown in FIG. 2B, when a current for generating a larger number of magnetic fluxes than the permanent magnet portion 3 is applied to the electromagnet portion 4 with the same poles facing each other, The lines of magnetic force of the permanent magnet unit 3 are the same as the lines of magnetic force of the electromagnet unit 4,
If it is pushed back above the joint surfaces D1 and D2 from the closed magnetic path and exceeds the saturated state of the permanent magnet portion 3, it is released into the air as shown by an arrow 9. At this time, if the number of magnetic fluxes of the electromagnet section 4 is sufficiently large, the magnetic lines of force emitted into the air are the combined ones of the permanent magnet section 3 and the electromagnet section 4.

Therefore, the attraction force of the joining surfaces D1 and D2 at this time is formed only by the electromagnet portion 4.
This state is called a second state.

Next, as shown in FIG. 2C, a current for causing the electromagnet section 4 to generate the same number of magnetic fluxes as the magnetic flux of the permanent magnet section 3 is applied so that the same poles as the permanent magnet section 3 are formed. A case will be described in which a current is applied to face the element and there is more room than the saturated state of the residual magnetic flux density of the basic factor 10 itself. Also in this case, the same poles are arranged so as to face each other as described above.

In this case, the joining surfaces D1 and D2 are
A neutralized state where neither suction nor repulsion occurs. This is because both the magnetic lines of force of the permanent magnet unit 3 and the magnetic lines of force of the electromagnet unit 4 are connected to the joint surfaces D1,
This means that they do not communicate with each other at D2. If the number of magnetic fluxes of the permanent magnet portion 3 and the electromagnet portion 4 exceeding the saturation state of the residual magnetic flux density of the basic factor 10 itself is equal and large, the joining surfaces D1 and D2 have a repulsive force, and each magnetic force line Is released into the air as a leakage magnetic flux. This state is called a third state.

In this third state, as shown in FIG. 3, the operating surface 3a of the basic factor 10 is set to X,
A movable or fixed suction member (Y) 4 close to X
Assume 0. The suction member (Y) 40 is made of a soft magnetic material such as pure iron.

In the state shown in FIG. 3, the value of the current supplied to the electromagnet section 4 is α. It should be noted that the value of α becomes smaller as the air gap between the basic factor 10 and the suction member (Y) 40 is reduced in the following state at the point where the joining surfaces D1 and D2 are disabled. This is because the magnetic field lines of the permanent magnet portion 3 do not exceed the joining surfaces D1 and D2 to form a closed magnetic path in the basic factor 10, but instead form a magnetic path through the air gap with respect to the attraction member (Y) 40. This means that a suction force is generated on the working surface (X) 3a. At this time, α to be supplied to the electromagnet portion 4 is sufficient to cut off the magnetic flux lines of the permanent magnet portion 3 at the joint surfaces D1 and D2, so that the magnetic flux lines of the permanent magnet portion 3 form a magnetic path with the movable member 40. The value of α decreases as the suction force of the working surface (X) 3a increases as the operation becomes easier. The limit of the attraction force of the working surface (X) 3a naturally limits the performance of the permanent magnet. This state is called a fourth state.

However, as in the second state, the electromagnet section 4
When a large amount of current is supplied to the working surface (X) 3a, the attractive force of the working surface (X) 3a becomes a combination of the magnetic lines of force of the permanent magnet portion 3 and the magnetic lines of force of the electromagnet portion 4, and can be increased. Gets worse.

In the fourth state, the working surface (X) 3
The conditions for increasing the suction force a and reducing the value of α are the following three conditions (1) to (3).

(1) The air gap on the working surface (X) 3a is reduced.

(2) The yoke portion of the permanent magnet portion 3 and the soft magnetic material portion of the attraction member (Y) 40 are made of a material having a higher saturation speed density than the core or yoke portion of the electromagnet.

(3) The distance L2 between the magnetic path formed with the attracting member (Y) via the permanent magnet portion 3 and the air gap is made shorter than the distance L1 between the closed magnetic paths within the basic factor 10. Needless to say, in order to increase the attractive force of the working surface X, the performance (Br, BH) of the permanent magnet portion 3 itself is improved. In addition, a material replacing the neodymium magnet, for example, a superconducting magnet can be used.

In the actual design, the distance (width) in the magnetizing direction of the permanent magnet portion 3 itself is L,
Assuming that the length of XL is XL and the cross-sectional area is Z, L and XL are
An appropriate value can be calculated from the Z, Br, BH curve graph and the permeance coefficient. Thereby, the optimal size of the permanent magnet part 3 and the attraction member (Y) 40 is obtained. The electromagnet section 4 compatible with the permanent magnet section 3 may be designed in consideration of the first to fourth states.

The configuration of the present invention in which the basic factor and the attraction member (Y) 40 are combined is different from the combination of the electromagnet 20 and the attraction member 40 in that the air gap, the material, the distance of the magnetic path, and the cross-sectional area are used. , Volume, coil thickness, tan number, etc.

For comparison, the input electric power when the attraction force on each working surface is the same between the device according to the present invention and the comparative example having only the electromagnet portion 4 and the attraction member 40 without the permanent magnet portion 3 In (W), it has been found that the present invention requires less than one third to one fourth of the comparative example having no permanent magnet portion 3.

Assuming a reluctance motor to which this comparative example is applied, the energy conversion efficiency is usually about 30%. However, if the reluctance motor using the present invention consumes less than 30% of the input power as compared with the form of the comparative example, an output exceeding the electric input can be obtained.
This indicates that the energy of the permanent magnet is converted into mechanical power.

FIGS. 4A, 4B and 4C are diagrams showing a continuum of basic factors according to the present invention.

Referring to FIG. 4A, a basic factor continuum 50 includes a pair of basic factors 1.
The side surfaces of the permanent magnet portions 0, 10 'are closely attached to each other such that the polarities of the permanent magnet portions 3, 3' are opposite to each other. Here, the lengths L1 and L2 of the respective magnetic paths are used again as the names of the respective magnetic paths.

As shown in FIG. 4B, the magnetic path L1 formed by the permanent magnet 1 having one basic factor 10 is counterclockwise. When an electric current is passed through the coil 7 so that a magnetic path is formed in a direction opposing this, magnetic force lines are emitted from the N pole of the permanent magnet 1 to the outside from the permanent magnet portion 3 as described above. The magnetic lines of force are emitted from the attraction member 40 to the permanent magnet portion 3 ′ again through the adsorbing material 40 and enter the permanent magnet portion 3.
Is formed as described above.

However, the basic factor 10
In addition, when the basic factor 10 'is set so that the magnetic poles of the permanent magnets are in opposite directions, that is, when the same poles are in contact with each other, not only the leakage magnetic flux forms L2, but also the leakage flux L2 as shown in FIG. As shown in c), basic factor 1
0 ', a part of the emitted magnetic field lines enters and the magnetic path L
3 and a counterclockwise magnetic path L4 is newly formed within the basic factor 10 '. The direction of the line of magnetic force of the magnetic path L4 is opposite to the direction of the magnetic path formed by the permanent magnet portion 3 'of the basic factor 10'.
As in the case of the basic factor 10, the lines of magnetic force are emitted outside the magnet to form a magnetic path L5. This is the coil 7 '
Although no current is flowing through the suction member 40 '
Will be sucked. This torque is about 1.5 times or more as compared with the one provided with one basic factor 10 despite the same amount of electricity.

I have.

Referring to FIG. 8, when a DC current of 10 A is applied to the coil using the basic factor, β becomes 0.
