Description

Electromagnetic Induction Driving Method and Device

The present invention relates to an electromagnetic induction driving method and apparatus for generating a driving force by electromagnetic induction by an AC power source.

Examples of the electromagnetic induction apparatus include three-phase induction motors and single-phase induction motors. Such a motor is arranged in a fixed outside stator by placing a constant constant number of pole coils, a cage-type rotor in the rotor, and applying an alternating current to each of the field coils to provide a rotor or moving magnetic field. It is causing In the case of a single phase induction motor, a capacitor is connected to the coil so as to shift the phase of the alternating current. Induces the induced current in the cage-type rotor by the difference of the relative moving speed of the rotor and the rotor and applies the electromagnetic force in the direction determined by Fleming's left hand law between the induced current and the rotor. It is rotating.

It is known that these induction motors have the following problems.

The field coil is a structure in which a predetermined number of coils are placed on the grooves formed on the inner surface of the stator core, so that the number of coils is constant. We had to rethink and prepare as many different types of motors as there were top combinations.

The rotational driving force includes vibration components twice the frequency of the power supply, and noise is generated when the low driving force is achieved. Since the rotational speed of the rotor is transmitting power to other devices through transmission means such as belts, pulleys, and gears, there is a reduction in transmission efficiency, power loss, and noise.

In addition, in the three-phase induction motor, if the two phases of the power supply are replaced, the generation direction of the rotating magnetic field is reversed. Therefore, reverse rotation of the drive shaft is easily performed. However, in the single-phase induction motor, the drive shaft cannot be reversed. Therefore, in order to reverse the rotational driving force obtained from the single-phase induction motor, the rotation of the drive shaft must be reversed in the power transmission device or the like, thereby increasing the size and complexity of the device.

The electromagnetic induction drive device of the present invention rotates or linearly moves the driving body by a principle different from that of a conventional three-phase or single-phase induction motor.

The apparatus of the present invention is formed of a conductive nonmagnetic material and has an outer magnetic body 2 and an inner magnetic body 3 on an outer side and an inner side, respectively, orthogonal to its moving direction with respect to a driving body 4 rotatably or linearly supported. Has placed.

In addition, a closed magnetic circuit is formed between the internal magnetic bodies 2 and 3 and passes the magnetic flux passing through the drive body 4 at three or more positions. The drive body 4 has edge portions 41 on both sides that are perpendicular to the moving direction and do not face the magnetic poles 22 and 23, that is, the magnetic flux does not pass. The magnetic flux passing through the closed magnetic circuit has a phase difference, and this phase difference of the magnetic flux causes the driving body 4 to move relative to one or both of the external and the magnetic bodies 2 and 3.

The apparatus of the present invention has a closed magnetic circuit in which magnetic flux penetrates the driving body 4 from the outer magnetic body 2, passes through the inner magnetic body 3, and passes through the driving body 4 again to return to the outer magnetic body 2. In terms of the configuration, a conventional induction motor composed of a stator and a rotor is different from the present invention in that it does not constitute a closed magnetic circuit penetrating the conductive portion of the cage-type rotor.

The present invention arranges the driving body 4 in the gap of the magnetic field circuit formed by the external magnetic body 2 and the inner magnetic body 3 facing each other, and mutually between three or more magnetic fluxes passing through the driving body 4. Give phase difference. As shown in FIG. 2D, the magnetic flux penetrating the driving body generates an induced current in the plane of the driving body 4. For example, the magnetic flux Φ ₂ flows in the direction of movement of the drive body at one edge 41 and flows in the reverse direction at the other edge 41 through the magnetic flux Φ ₁ of the adjacent magnetic circuit penetrating the drive body 4 and drives again. Generates an induction current I3 that circulates through the magnetic flux Φ ₃ of the other magnetic circuit penetrating the sieve 4 and between the magnetic flux Φ ₁ , Φ ₃ and the induction current I3 with respect to the drive body 4. It acts to rotate or linearly move the driving body 4.

The first object of the present invention is to form the inner body 3 and the driving body 4 into a cylindrical body, and to form the magnetic body 22 and the driving body 4 on the outer body 2 by forming a magnetic pole 22. It provides a method and apparatus for rotating (figure 5a, 5b)

The second object of the present invention is to form and integrate the outer magnetic body 2 and the driving body 4 into a cylindrical body, and to form the magnetic pole 32 in the inner magnetic body 3 so that the outer magnetic body 2 and the driving body 4 are formed. To provide a method and a device for rotating (figure 6 a, 6b).

A third object of the present invention is that at least one of the internal and external magnetic bodies 2 and 3 has three or more magnetic poles 22, at least one of which is the forward and reverse common coil 51, and the other magnetic pole is a forward drive. The coil 61 for power and the coil 71 for reverse drive are provided, and the normal and reverse drive coil 51 is electrically connected in series with the AC power supply 52, and the closed electric circuit 5 is comprised, One of the coil 61 and the reverse driving coil 71 can be replaced, and the capacitor circuits 6 and 7 are configured and driven by electrically connecting the capacitance or resistance or an electric element 63 of a combination thereof in series. The present invention provides a method and apparatus for generating a positive or inverse phase difference between magnetic fluxes passing through a sieve 4. (FIGS. 1A and 1B)

EMBODIMENT OF THE INVENTION The Example of the electrophoretic drive apparatus which concerns on this invention is described with reference to drawings.

Figure 1a shows the basic structure of the present invention, which is modified in various embodiments described below. The outer magnetic body 2 protrudes three iron cores 231, 232, 233 from the yoke 21 to enlarge the iron core tip, and the inner circumferential surface forms a circular arc.

The first and second iron cores 231 and 232 respectively have the field coils 51 and 61 and the third iron core having the field coils 71.

The coil 51 of the first iron core 231 is connected to an AC power source of, for example, 60 Hz by the closed electric circuit 5 and is energized.

The inner magnetic body 3 is formed in a concentric cylindrical shape with an arc of the inner circumferential surface of the magnetic pole 22, and a cylindrical driving body formed of a conductive nonmagnetic material in the gap between the magnetic pole 22 and the inner magnetic body 3. (4) is arranged as a rotating material.

The driving body 4 is a cylindrical body having a uniform thickness, and the width thereof, that is, the length of the direction orthogonal to the rotational moving direction is formed larger than the width of the magnetic pole 22. The magnetic poles 22 are arranged opposite to the substantially middle portion of the driving body 4, and therefore, both ends of the driving body 4 are provided with edges 41 which do not face the magnetic poles 22.

Each of the coils 61 and 71 of the second and third iron cores 232 and 233 connects one end to each other, and the other end thereof is switched by the switch 64, one of which opens a circuit and the other of a capacitor or And a closed circuit by electrically connecting in series with the electrical element 63 of a resistor or their combination. When the coil 61 is connected to the electric element 63 by the switch 64, the magnetic flux of the electric circuit having the coil 61 and passing through the driving body 4 via the second iron core 232 is internal. It penetrates itself 3 and it penetrates a drive body again, and returns to the outer magnetic body 2 via the 1st iron core 231 and the 3rd iron core 233 which have coils 51 and 71. FIG. In this way, the magnetic circuit of each coil is formed. Therefore, a positive magnetic flux with a phase difference occurs in each magnetic pole 22.

When the switch 64 is switched so that the coil 71 is connected to the electric element 63, the electric circuit having the coil 71 has a different magnetic pole since the position of the coil 71 is different with respect to the coil 61. 22, reverse magnetic flux with phase difference occurs.

FIG. 1B is a planar view of the configuration of FIG. 1A for convenience of description. When the device is cut out and deployed along the line B-B in Fig. 1A, it corresponds to Fig. 1B. The same reference numerals as in FIG. 1A show the same parts.

Next, the driving principle of the drive body 4 is demonstrated.

As shown in FIG. 2A, when one magnetic pole 22 is opposed to the driving body 4 of the non-conductive material of conductive nature, when an alternating current flows through a coil provided at the iron core of the magnetic pole, the magnetic body 2, The magnetic flux Φ flowing in the closed magnetic circuit including 3) concentrates on the magnetic pole 22 and penetrates the driving body 4. Induction current I3 circling the outer side of the magnetic pole 22 flows in the inner surface of the drive body 4 in proportion to the amount of temporal change of the magnetic flux Φ.

The reason why the induced current I3 occurs can be explained as follows. When the magnetic flux Φ through the coil of number n changes in time, the induced electromotive force at time t at both ends of the coil

It is well known that

In FIG. 2, an area outside the opposing area A with the magnetic pole 22 in the plane of the driving body 4 can be regarded as a coil with a number of turns n = 1, so that the current determined in relation to Kirchhoff's second law Flows. That is, if the equivalent resistance of the outer region of the region A is r3, the induced current I3,

Occurs.

The direction and magnitude of the induction current I3 are changed by temporal changes in the direction of the magnetic flux Φ and the magnitude of the magnetic flux Φ. For example, in Fig. 2, when the magnetic flux Φ flows upward with respect to the ground and the magnetic flux φ is changed in a direction in which the magnetic flux Φ becomes strong, the induced current I3 flows in the direction of travel of the right screw by Faraday's law.

Since the magnitude of the induced current I3 is inversely proportional to the equivalent resistance r3 to the current flowing in the plane of the driving body 4, the current I3n close to the magnetic pole 22 is large and the current reduced from the magnetic pole 22 in Figs. 2a and 2b. I3f is small (I3n> I3f)

In addition, as shown in FIG. 2C, when the magnetic poles 22 are overlapped with the edges of the driving body 4, the induced current does not flow round the magnetic poles 22, so that no induced current occurs. Induced current I3 is generated when the drive body 4 has edges 41 and 41 on both sides of the pole 22 that are larger than the width of the pole 22 and are not opposed to the pole 22.

In FIG. 2D, the areas occupied by the magnetic poles 22 of the first, second and third iron cores 231, 232 and 233 on the driving body 4 are respectively A1, A2 and A3. Considering the case where only the coil 61 of the second iron core 232 is energized, the driving body 4 generates an induction current I32 which is circumscribed outside the region A2 and is applied to the region A1 or A3. In the region A2 immediately below the magnetic pole 22, the induced current generated by the adjacent magnetic flux is mutually offset, so that no induced current occurs in the region.

FIG. 2D is a simplified view of the drive body 4 and the three magnetic poles 22 in FIG. 2B. As the alternating current flows through the two coils 51 and 61, the magnetic flux phi 1 and phi 2 which change in time penetrate the regions A1 and A2.

The first iron core 231 is connected to a closed magnetic circuit penetrating the second and third iron cores 232 and 233 and the yoke 21 of the inner magnetic body 3 and the outer magnetic body 2 and thus the coil of the first iron core 231. The magnetic flux Φ 1 generated by the 51 passes through the driving body 4 in the region A1 via the magnetic pole 22, and each magnetic flux returns to the yoke 21 via the iron cores 232, 233.

In the same manner, the magnetic flux Φ 2 generated by the coil 61 of the second iron core 232 flows through the driving body 4 from the region A2 to the inner magnetic body 3 via the magnetic pole 22, and the regions A1 and A3. Branched into two and penetrates the driving body 4, and each magnetic flux is joined from the yoke 21 via the iron cores 231 and 233 to return to the previous second iron core 232.

The coil 71 is wound around the third iron core 233 of the magnetic pole 22 opposite to the region A3, but no current flows because no current flows. However, the magnetic flux Φ 1, Φ 2 generated by the coils 51, 61 of the first and second iron cores 231, 232 returns from the inner magnetic body 3 to the outer magnetic body 2, and thus branched therein to form the third iron core 233. The magnetic flux Φ 3, which adds up the total amount through), penetrates the driving body 4 of the region A3 via the magnetic flux 22.

The electrical elements 63 connected to the coil 51 of the first iron core 231 and connected in the closed electric circuit to shift the phases of the magnetic fluxes Φ1 and Φ2 by 120 ° and have the same size. When the conditions between the magnetic circuit and the amount of magnetic circuit are properly set, the magnetic flux Φ1 and Φ2 become as follows.

Where ω = 2, π, f, f = power frequency

The magnetic flux Φ 3 through the third iron core 233 is set by appropriately setting the conditions of the magnetic circuit.

It is possible to do

The equivalent resistance r30 around each of the regions A1, A2, and A3 of the driving body 4 is the induced currents I31, I32, and I33 generated by the magnetic flux Φ1, Φ2, and Φ3 as follows.

The induced current I3 with respect to the magnetic flux Φ is a waveform shifted by 90 degrees out of phase as shown in Figs. 3A-3C and has a relationship of Φ1 + Φ2 + Φ3 = 0 at an arbitrary time t0.

In FIG. 2D, the induction current I32 circumscribes the outside of the area A2 and passes through the areas A1 and A3 is induced by the magnetic flux Φ2 passing through the second iron core 232.

The magnetic flux Φ 1 acts on the current I32 applied to the area A1, and an electromagnetic force F21 is applied in the direction determined by the Fleming's left hand law. In the same way, the magnetic flux Φ 3 acts on the current I32 and the electromagnetic force F23 is applied to the region A3. Two electromagnetic forces F21 and F23 become a force F2 to rotate or linearly move the driving body 4.

Since the driving body 4 is actually a cylindrical body as shown in FIG. 1A, the drive body 4 induces the current I31 applied to the magnetic fluxes of the regions A3 and A2 in FIG. 4A, and is induced by the magnetic flux Φ3 through the region A3 in the same manner. The current I33 applied to the magnetic flux in the regions A2 and A1 is induced.

Electromagnetic force F1 acting on the drive body 4 because the induced currents I31, I32, I33, in which the magnetic fluxes Φ1, Φ2, and Φ3 penetrating the respective areas A1, A2, A3, are induced in the plane of the drive body 4, may overlap. , F2, F3 can also overlap.

The magnetic flux Φ1, Φ2, and Φ3 through the three magnetic poles 22 are set to the same magnitude at the phase difference of 120 ° as described above, and the equivalent resistance r3 around the areas A1, A2 and A3 is set equal to each other. (4) In-plane induction currents I31, I32, and I32, as described above, change with time t in the same phase at 90 ° shifted with respect to magnetic flux Φ1, Φ2, and Φ3. Therefore, the electromagnetic force F synthesized by overlapping the electrodes F1, F2, F3 is

Where L0: the width of the stimulus 22 or the stimulus 32

A0: The cross-sectional area of the magnetic pole 22 or the magnetic pole 32 is shown.

It can be seen that the magnitude and direction are the constant vibration-free force F at any time regardless of time t. When the driving body 4 is cylindrical, the electromagnetic force F becomes a rotational force acting in the circumferential direction and rotates the driving body 4.

The drive body 4 having the external body 2, the internal body 3, and the drive body 4 unfolded as shown in FIG. 1B and arranged in parallel with the same plane is arranged with the edges 41 and 41 at both sides as shown in FIG. 4B. The drive part 42 of the center may be separated, and the both ends of each edge part 41 may be electrically connected with the electric circuit 43 which formed the electric wire, and the drive part 42 may be made to slide with the edge parts 41 and 41 of both sides. In this case, when the drive body 4 is a flat plate, the electromagnetic force F becomes a linear force acting in a linear direction, and can linearly move the drive body 4.

It is not necessary to limit the number of the magnetic poles 22 to three, and when the closed electric circuits 5, 6, and 7 are connected to the coils arranged at each of the magnetic poles by arranging the magnetic poles of multiples of three, It can apply rotational or linear force.

In addition, the inner body 2 and 3 are replaced, and the outer body 2 is a cylinder having only the yoke 21. Even if the inner body 3 is provided with an iron core, a magnetic pole, and a coil, the driving body 4 is maintained. The principle of rotation or linear movement is the same.

When the conditions of the electric and magnetic circuits are set so as to deviate by 120 °, the electromagnetic force F in the forward or reverse direction to the driving body 4 is induced by the induced current I3 generated in the driving body 4 and the magnetic flux Φ penetrating the driving body 4. And the drive body 4 rotates in the forward or reverse direction.

No alternative means of conversion is required.

In addition, if a predetermined number of taps are drawn out to the coil to cope with the difference in frequency and voltage of the AC power supply, the appropriate tap is selected and connected to the conductor 11, so that the rotation or torque of the driving body 4 can be kept constant. There is no need to prepare a variety of motors to match the power frequency and voltage.
