Description

Magnetic circuit of rotor

The present invention relates to a magnetic circuit of a rotor in which a magnetic pole piece (surface) of a field or armature can be configured parallel to an axis to obtain power or electromotive force.

Rotating devices and synchronizers that have been used up to now are constructed vertically when the magnetic pole pieces (surfaces) of the field magnet 5 and the armature 6 are placed horizontally (using the expression "about the axis"). (5) → armature (6) → yoke (YORK) (7) → armature (6) → vertical magnetic circuit circulated from field (5).

FIG. 1A is a diagram schematically illustrating a vertical motor in which a magnetic flux is perpendicular to a conventional axis, and FIG. 1B is a diagram illustrating a magnetic field flow of a conventional vertical motor.

As shown in Fig. 1A, the conventional apparatus is largely composed of an annular stator 1 and a rotor 2 that rotates inside the annular stator 1. The annular stator 1 is composed of an armature 6 and yoke [YORK] 7, and the rotor 2 is composed of an axis 3 and a field 5.

FIG. 1B is different from the above-described FIG. 1A in that the field 15 is located outside, and the armature 16 which rotates together with the shaft 13 is located therein. In FIG. 1B, the flow of magnetic field 18 is shown, which inevitably produces a sinusoidal wave.

In addition, as can be seen in Figure 1a the magnetic pole piece of the field 5 is configured in the vertical direction with respect to the axis and mechanical vibrations due to the magnetic force flow of the magnetic force of the suction force and the repulsive force acting to rotate to apply a significant stress to the axis .

In particular, this phenomenon is particularly burdensome at high rotations.

To solve these problems, the technicians had to devote a lot of effort to the development of high-strength materials with high manpower and high precision machining technology.

In addition, in the conventional magnetic circuit of the vertical motor, the material loss due to the energy loss and unnecessary magnetic circuit configuration due to the magnetic loss due to the magnetic resistance due to the multi-step magnetic flow and the iron loss due to the material that is not necessary increases the maintenance cost and the production cost. It acted as a factor.

As shown in Figs. 2A to 2C, a complicated circuit including a plurality of diodes D1 to D6 and a Y connection is required in order to rectify the AC waveform into a DC waveform (virtually a pulse wave waveform). Such complex circuits cause many malfunctions due to the limitation of the precision of the device, and above all, a plurality of filters with high precision are required to obtain a waveform close to a full direct current.

However, virtually no direct current is possible, which causes many problems for actuators requiring direct current. In other words, the DC power supply device for use in applications requiring high voltage such as laser power supply requires high power electronic technology and advanced electronic devices. Therefore, high cost is required to obtain the DC power waveform. The energy consumption of the device is serious.

It is to provide a magnetic circuit of a rotator to obtain a high torque rotational force by high-efficiency electromotive force and electrical energy.

Another object of the present invention is to obtain a propulsion force by using a convective phenomenon of air that is caused by the propeller is rotated by mounting the propeller between the shaft and the support connecting to the rotor or the support, or electromotive force by mechanical propulsion [wind force] To provide a magnetic circuit to obtain.

Still another object of the present invention is to provide a magnetic circuit capable of absorbing mechanical vibrations caused by suction and repulsive force to obtain ultra-high rotational power.

It is still another object of the present invention to reduce the magnetic field acting when electromotive force is generated by inducing a spiral magnetic flux in a magnetic circuit structure of a matrix (MATRIX) structure that gives a plurality of fields or a plurality of armatures a torsion angle, and mechanical power To provide a magnetic circuit for obtaining a high speed rotational power in the occurrence of.

It is still another object of the present invention to provide a magnetic circuit in which a field and an armature are formed in multiple layers on one axis so that one layer is used as an exciter for exciting the field and the other layer is used as a rotator or a synchronizer.

According to an aspect of the present invention for achieving the above object, a magnetic circuit used for a generator or an electric motor, comprising: a rotating shaft; A plurality of supports fixedly installed on the rotation axis in a direction perpendicular to an outer circumferential surface of the shaft; A rotor installed at one end of the support in parallel to the axis to rotate by suction and repulsion of the magnetic field; A stator (an armature) having a coil wound around the body to induce an alternating magnetic flux of the rotor generated when the rotor is spaced apart from the outside of the rotor; A magnetic circuit of the rotor is provided.

According to a preferred feature of the invention the rotor has a magnetic body to facilitate the rotational movement.

According to another preferred feature of the invention, the armature is one of C type, U type, I type, S type, inverse S type, and diamond type.

According to another preferred feature of the invention, the propeller may be mounted on a support between the shaft and the rotor.

As shown in FIG. 3, the rotor 27 is fixed through the support 29, and the pole pieces of the rotor 27 are provided in parallel with the shaft 23. Moreover, the pole piece (surface) is comprised in parallel with the shaft 23 by the stator 26 by which the coil 28 was wound.

In this embodiment, for the sake of explanation of the rotation action, a four-pole three-phase rotor is shown for convenience.

Thus, each stator 26 consists of a stator 26 while maintaining a 60 ° C angle, although not shown, these stators 26 are fixed by the housing. The rotor 27 is provided at one end of the support 29 fixed to the shaft 23 while maintaining the angle of 90 ° C. The polarities of the rotors are opposite in polarity to adjacent rotors, respectively, as shown in FIG. 3.

The change in the number and polarity of the stator 26 and the rotor 27 described above may vary depending on the designer's intention. In addition, the propeller between the shaft 23 and the support between the rotor 27 or the support may cause convection of air to enhance propulsion.

Although the generator according to the present invention having such a structure is not shown, when the shaft 23 is rotated by external power, the waveform of the magnetic field is generated as shown in FIG. 4A. Thus, the electromotive force waveforms are square waves as shown in FIGS. 4B to 4E, respectively. Occurs. Of course, the triangular wave of FIG. 4A is produced by the magnetic circuit configuration of the matrix [MATRIX] structure and the current control of the field in the apparatus according to the present invention.

Sinusoidal waves can also be created by the phase spacing and the field structure.

Figure 5 shows a load state diagram of a generator according to an embodiment of the present invention.

As shown, based on the example of the 4-pole 3-phase, the armatures 52-1- and 52-2, which form a body and have a torsional structure, are given polarities when no load is applied when the field is given from la to la. Although this does not appear, it is a general theory based on Lenz's law that a polarity opposite to the flux flow is induced under load.

However, according to the present invention, when the field Ga tries to exit the magnetic pole pieces 52-1, 52-3 of the armature as Ra proceeds by external force, 52-2) as the polarity is induced to N1, the field pulls to prevent rotation, push the field to help the direction of rotation.

By this method, it is a characteristic element of the present invention not seen in the existing generator that the action and reaction of the armature occur together.

In this case, the angle of the field may be arranged at 90 ° C. uniformly and differently if necessary.

FIG. 6 is a diagram illustrating magnetic flow when operating a motor when the rotor is applied current to the stator coils in six single-phase motors spaced at 60 ° C. in the digital generator of FIG. 3 described above. FIG. It is an operation explanatory diagram.

Therefore, in the form as shown in Figure 3, only the support and the rotor is further installed at intervals of 60 ℃. For the sake of convenience, the explanation is replaced with an explanatory diagram to understand the flow of self.

As shown in FIG. 6, the stator 61 and the rotor 63 having the coils wound 32 are shown. In FIG. 7, the magnetic pole pieces of the stator 71-2 and the stator 7-3 ( Surface) is configured to induce a helical magnetic flux by giving an angle of twist (SKEW) as an integral stator 71 so that the rotational force of the rotor 73 occurs smoothly.

That is, the magnetic flux of the rotor magnetic field 63 passes through the air gap and is induced to the magnetic pole piece 61A of the armature which is the stator, and the induced magnetic flux 65 is again rotated along the armature 62-1 of the stator. This magnetic flux again reaches the magnetic pole 69 of the armature 61-1, which is the stator, and advances to the next rotor.

In FIG. 7, when the polarities of the rotor 73-1 are given as N and S, the induced repulsion force is induced to be N1 and S1 of the stator armatures 71-1 and 71-2, which constitute one body. In addition, the rotating magnetic field 73-2 positioned below receives a phase from a phase sensing unit (not shown) to suck and generates rotational force in the direction of arrow A by supplying alternating power from the inverter according to the phase value.

As the magnetic flux of this phenomenon is continuously repeated, a helical magnetic flux can be induced to obtain rotational or linear driving force.

The apparatus according to the present invention can achieve the following effects through some embodiments.

In other words, when acting on the generator, the electromotive force waveform is square wave, so the DC conversion characteristics are excellent and the redundancy in the magnetic circuit is small, so only the necessary materials are processed, so that the material loss is small. To reduce energy loss.

In addition, since the net action and the reaction action at the same time under load, it is possible to minimize the mechanical energy, and to minimize the loss during the conversion from AC to DC.

On the other hand, when applied to an electric motor, the suction force and the repulsive force are rotational movements due to the horizontal action about the axis, so the vibration wave is easily absorbed by the mechanical vibration, so that high-speed rotation is possible, and skew space is secured and the torsion angle is easy. Cogging torque can be greatly reduced.
