The technical field

The present invention relates to a generating device, in particular to the generator forward rotation.

The level of technology

Traditional generator has the following disadvantages: first, when the rotor (pole) and the stator (coil) traditional generator are in relative circular movement, the lines of magnetic forces and the winding are in relative shear movement, the main magnetic flux and eddy magnetic field generated by the induced current winding, create a tangential force in the direction opposite to the direction of rotation of the rotor, which creates resistance to the rotor. To meet the operational requirements of the generator, the input power should be much more of such electromagnetic resistance. The higher electromagnetic resistance, the more energy. This mode of generation can only convert part of the energy conversion efficiency is low, and the power consumption is high. Second, in the iron core of the traditional generator can be no leakage of magnetism and harmonic waves, which negatively affects the network. In addition, the space between the iron core and the poles must be reduced in order to increase the efficiency of the generator, because the smaller the space, the smaller magnetic the resistance it creates the air, and the higher the efficiency of the generator. Optimized scheme is that the iron core is in direct contact with the poles, to ensure that most of the lines of magnetic forces through the iron core. However, on the one hand, to processing technologies, high demands, and the production cost of generators increases significantly with decreasing space between the iron core and the pole; on the other hand, are used as the solid iron cores and poles, the generator efficiency is difficult to optimize, if the frictional force resulting from direct contact is too large.

Disclosure of inventions

The purpose of the present invention is to provide a generator of direct rotation, which induces an electromotive force in the coil by the changing magnetic flux in the iron core of the generator instead of cut lines of magnetic forces in the winding. Lines of magnetic forces of the vertical winding iron core, and the direction of relative rotation of the iron core and the magnet. Therefore, the main magnetic flux generator forward rotation and the magnetic flux generated by the induced current, parallel iron core in it, which greatly reduces the impact resistance to the relative rotation is giving the iron core and the magnet, thus saving energy for electricity generation. It is unlikely that leakage of magnetism and harmonic waves will occur in the iron core, thus not damaging the network and further eliminating the disadvantages of conventional generator. In addition, the magnetic resistance between the pole and the iron core can be eliminated, this significantly increasing the efficiency of the generator.

The objective of the invention is implemented in the following technical scheme. The generator includes a holder of the iron cores and the rotating shaft is mounted on a holder of the iron cores. The first rotating disk and the second rotating disk located at the ends of the rotating shaft. The first iron core is located on the holder of the iron cores, and the first winding is located on the periphery of the first iron core. The first sealing plate is located on the first rotating disk, the first magnet is located on the first rotating disk or on the first sealing plate, and the first magnet and the first sealing plate share the same surface. The fourth magnet is located on the second rotating disk, the first magnet and the fourth magnet correspond to the two ends of the first iron core, and the first magnet and the fourth magnet are facing each other opposite poles. The tank d is I the liquid, which is filled with magnetic solution is located at the end of the first iron core, and the end of the first magnetic core, filled with the magnetic fluid is in contact with the first sealing plate.

For the further implementation of the objectives of the invention also use the following technical scheme, the second iron core and the third iron core is located on the holder of the iron cores. The first iron core, the second iron core and the third iron core evenly spaced on the periphery of the rotating shaft. The first iron core, the second iron core and the third iron core have the same center of the circle. The second winding is located on the periphery of the second iron core, and the third winding is located on the periphery of the third iron core. The second magnet is located on the first rotating disc and separated from the first magnet by the same distance as the rotating shaft. The second magnet and the first magnet is located at an angle of 180 degrees to each other. The fifth magnet is located on the second rotating disk and separated from the fourth magnet at the same distance as the rotating shaft. The fifth magnet and the fourth magnet are arranged at an angle of 180 degrees to each other. The fifth magnet and the second magnet facing each other opposite poles. The surface is atogo magnet and the surface of the second sealing plates share the same surface, and the surface of the second magnet and the first sealing plate also share the same surface. The shape and dimensions of the end surfaces of the first iron core, the second iron core, the third iron core, a first magnet, the second magnet and the fourth magnet and the fifth magnet is the same. The direction of the poles of the first magnet and the second magnet is opposite. The direction of the poles of the first magnet and the second magnet in the same way. A number of external magnetic blocks are located on the first rotating disk and evenly distributed on the periphery, if we take the rotating shaft as the center of the circle. A number of internal magnetic blocks is located on the holder of the iron cores and evenly distributed on the periphery, if we take the rotating shaft as a center of cool. The vertical distance between the outer magnetic blocks and the rotating shaft is equal to the distance between the internal magnetic blocks and rotating shaft. Internal magnetic blocks correspond to the external magnetic blocks and poles of the same polarity facing each other. A number of external magnetic blocks are located on the second rotating disk and evenly distributed on the periphery, if we take the rotating shaft as the center of the circle. A number of internal magnetic the locks located on the holder of the iron cores and evenly distributed on the periphery, if we take the rotating shaft as the center of the circle.

The fourth magnet and the second sealing plate share the same surface. The two ends of the first iron core are in contact, respectively, with the first sealing plate and the second sealing plate. The second sealing plate also has an annular design.

The positive effect of the invention is that the generator forward rotation generates an electromotive force in the coil by the changing magnetic flux in the iron core of the generator. The strength of the induced current related to the rate of change of magnetic flux and electric resistance wire load. When the generator, i.e. during relative rotation of the iron core and the magnet, the lines of magnetic the x force is always vertical to the end surface of the iron core, i.e. the direction of rotation changing magnetic flux in the iron core, is always at 90 degrees to the direction of the lines of magnetic forces of the magnet. This design can significantly reduce the resistance to rotation between the stator and rotor of the generator, to increase the efficiency of the generator and conserve large amounts of energy. Generating device may not cause leakage of magnetism or harmonic waves, reduces resistance, saves energy and does not harm the network. The magnetic fluid is filled in both ends of the iron core that keeps most parts between the poles and the core solid and liquid, this eliminating the magnetic resistance between the iron core and the pole, increasing the efficiency of the generator, reducing the friction force between the iron core and the poles to a minimum and reducing the consumption of energy for generation of electricity. The holder of the iron cores provides sufficient support to the iron core, which can effectively prevent swinging of the iron core under the action of external forces, creating unnecessary friction and helping to extend engine life. A rotating disk with poles has the advantages of small size, low weight and easy handling and installation. In addition, the generator forward rotation also is has the advantages of long life, ease of operation, simple and compact design, small cost to manufacture, and safe and convenient use.

Detailed description of embodiments

The generator contains forward rotation of the holder 1 of the iron cores and the rotating shaft 4, mounted on a holder of the iron cores 1. The first rotary disk 2 and the second rotating disk 3 are located on both ends of the rotating shaft 4. The first iron core 5 from Ojen on the holder of the iron cores 1, the first coil 14 is located on the periphery of the first iron core 5. The first sealing plate 22 is located on the first rotary disk 2, the first magnet 8 is located on the first rotary disk 2 or the first sealing plate 22 and the surface of the first magnet 8 and the first sealing plate 22 share the same surface. The second sealing plate 23 is located on the second rotary disc 3 and the second rotating disk 3 or the second sealing plate 23 has a fourth magnet 11, which divides one surface with the second surface of the sealing plate 23. The first magnet 8 and the fourth magnet 11 correspond to the two ends of the first iron core 5, and the first magnet 8 and the fourth magnet 11 are facing each other opposite poles, making the lines of magnetic forces of the first magnet 8, facing to the fourth magnet 11 can pass through the first iron core 5 during the rotation of the first rotary disc 2 and the second rotary disc 3. The reservoir for the liquid 19 is filled with the magnetic fluid 20 is located at both ends of the first iron core 5, and both ends of the first iron core 5 in contact with the first sealing plate 22 and the second sealing plate 23, respectively. Two side magnetic fluid 20 iron gel core is and can reduce the contact surface of the solid parts of the iron core and the magnet, so most of the parts between the iron core and the magnet are in solid and liquid contact, and effectively reduce the friction force between the iron core and the magnet. Magnetic fluid 20 has a relatively good magnetic conductivity, and direct contact poles can eliminate the magnetic resistance between the poles and the iron core to a minimum and to increase the efficiency of the generator. Since the magnetic fluid 20 is poured into both ends of the iron core, to prevent leakage of the magnetic fluid 20 from the reservoir 19 to the first sealing plate 22 mounted on the first rotary disk 2 and the second sealing plate 23 mounted on the second rotary disc 3, providing sealing of the tank 19 during rotation. To reduce the cost of producing a reservoir for the liquid, filled with the magnetic fluid 20 can also be located on only one end of the first iron core. The second sealing plate 23 does not have to be installed on the second rotating disk 3, and the fourth magnet 11 on the second rotary disc 3. However, in this case, the effect of eliminating the magnetic resistance between the iron core and the poles will be worse.

The reservoir 19 for the liquid can be installed on both ends of the iron cores, such as the PE the first iron core 5, and can be performed by connecting the ring-shaped parts made from materials such as copper or aluminum, on both ends of the first iron core 5. In other words, the channel 19 for liquid surrounded by such materials as copper or aluminum.

The first rotary disk 2 and the second rotating disk 3 is borne by the first magnet 8 and the fourth magnet 11, which is installed as a pole. The first rotary disk 2 and the second rotating disk 3 can provide the rotation of the magnet relative to the iron cores, such as the first iron core 5. The holder 1 of the iron cores is a part for fixing the first iron core 5, in order to prevent the swinging of the first iron core 5 due to the impact of external forces at work. There might also be other structures that implement the function of the rotation of the pole relative to the iron core. For example, in the mechanism with a rotating cylinder and the fixed shaft replaces the last holder 1 iron cores, on a fixed shaft is a support rod, and the iron cores, such as the first iron core 5, a fixed support rod. The rotating cylinder is located on the periphery of the fixed shaft and rotates relative to the fixed shaft, i.e, fixed poles are located on the inside of the sides of both ends of the rotating cylinder instead of the first rotary disc 2 and the second rotary disc 3, and the magnetic poles are located inside both ends of the rotating cylinder. The generator mechanism with a rotating cylinder and the fixed shaft can implement relative rotation of the poles, but has the following disadvantages: first, assuming the same materials and the mass production of the fixed shaft with the supporting rods and holder 1 iron core strength of the fixed shaft with the supporting rods is much lower than that of the holder 1 iron cores. In the production of the fixed shaft with the supporting rods are totally unable to provide sufficient support iron cores, such as the first iron core 5; also the operation of the generator external force acting on the iron cores, such as the first iron core 5, may change periodically and required great strength. Swinging iron cores, such as the first iron core 5, which is not provided with effective support and fixation, can directly affect the efficiency of the generator, causing unnecessary friction, which significantly reduces the service life of the generator. Compared to the fixed shaft with the supporting rods, the holder 1 of the iron cores can provide sufficient support to the first iron core 5, this effectively prevents the swinging of the first iron heart condition the ICA 5 under the action of external forces, avoiding friction and prolonging the service life of the engine. Second, the volume of the rotating cylinder is much larger than the total volume of the first rotary disc 2 and the second rotary disc 3, which increases the power consumption by bringing the poles during rotation. In addition, the processing technology of the rotating cylinder is much more difficult for such a rotating disk, which increases the production cost of the generator. Also more difficult to place the pole in the rotating cylinder, which increases production costs. Compared to the rotating shaft, the first rotary disk 2 and the second rotating disk 3 have the advantages of small volume, low mass, the smaller the difficulties of manufacture and placement of the poles. Third, the mechanism with a rotating cylinder and the fixed shaft, the mass of the iron core, the poles and the rotating cylinder carries a fixed shaft, so the requirement for the strength of the fixed shaft is increased, and the production cost of the generator increases. However, the service life of the generator mechanism with a rotating cylinder and the fixed shaft is much smaller than the oscillator holder 1 iron cores, the first rotary disk 2 and the second rotating disk 3. Therefore, the manufacturer of the generator mechanism with a rotating cylinder and the fixed shaft hard, industrial scale on the misfit is unlikely, and the production of large generator power for electricity generation is impossible. The generator forward rotation according to the invention can perform the same function and have more power.

The generator forward rotation can be represented by two schemes, namely, with the rotation of the magnet and the rotating iron core.

Scheme with the rotation of the magnet

The first rotary disk 2 and the second rotating disk 3 is rigidly connected with a rotating shaft 4, which is connected with a energy such as a generator or a hydraulic motor. On the rotating shaft 4 is the blade to use wind power or water for the rotation of the rotating shaft 4. When the generator holder 1 iron cores fixed, and the rotating shaft 4 rotates the first rotary disk 2 and the second rotating disk 3 relative to the first iron core 5, providing simultaneous rotation of the first magnet 8 and the fourth magnet 11 relative to the first iron core 5.

During rotation of the magnetic flux on the surface of the first iron core 5 is as follows: when the first magnet 8 and the fourth magnet 11 rotates into position on one line with the first iron core 5, the magnetic flux of the first iron core 5 will be the greatest. When the far is Shem the rotation of the first magnet 8 and the fourth magnet 11 and the magnetic flux of the first iron core 5 is gradually reduced to zero. When you return to the first magnet 8 and the fourth magnet 11 to the first iron core 5, the magnetic flux of the first iron core 5 again increases from zero to maximum. During the repeated changes in the magnetic flux induced electromotive force is generated in the first coil 14 located on the first iron core 5.

Scheme with the rotation of the iron core

The first iron core 5 is rigidly connected to the rotating shaft 4 via the cradle 1 iron cores. The holder 1 of the iron cores and a iron core can rotate on the rotating shaft 4 relative to the first rotary disc 2 and the rotary disc 3. The change of the magnetic flux and the principle of generation are the same as for the scheme with the rotation of the magnet. As shown in figure 2 - Figure 4, holder of the iron cores 1 can be additionally located the second iron core 6 and the third iron core 7. The first iron core 5, the second iron core 6 and the third iron core 7 are evenly distributed on the periphery of the rotating shaft 4 and have the same center. The second coil 16 is located on the periphery of the second iron core 6, the third winding 15 is located on the periphery of the third iron core 7, the second magnet 9 is located on the first rotary disk 2,and the second magnet 9 and the first magnet 8 have the same distance to the rotating shaft 4, the second magnet 9 and the first magnet 8 arranged at an angle of 180 degrees to each other, the fifth magnet 12 is located on the second rotary disc 3, and the fifth magnet 12 and the fourth magnet 11 have the same distance to the rotating shaft 4, the fifth magnet 12 and the fourth magnet 11 is located at an angle of 180 degrees to each other, and the fifth magnet 12 and the second magnet 9 facing each other opposite poles. During rotation induced electromotive force can be generated in the first winding 14, the second winding 15 and a third winding 16, generating three-phase electricity. The number of iron cores corresponds to the number of phases, i.e., one iron core to the holder of the iron cores can generate single-phase electricity; two iron core give a two-phase electricity, four iron core give the four electricity, etc. thus can be manufactured polyphase generators to meet the needs of users.

As shown in figure 2 - Figure 4, to increase the generation of shapes and sizes of surfaces, first, the first iron core 5, the second iron core 6, the third iron core 7, and secondly, the first magnet 8, the second magnet 9, the fourth magnet 11 and the fifth magnet 12 are identical. Thus, the change of the magnetic flux is on a surface of the first iron core 5 per unit time is greatest when the condition is identical to the frequency of rotation. The opposite pole of the first magnet 8 and the fourth magnet generator 11 form a pair, called unipolar. The generator may be bipolar, tripolar or multipolar. The generator shown in figure 1, has two poles, one of which is formed by the first magnet 8 and the fourth magnet 11, and the other the second magnet 9 and the fifth magnet 12. Each pole consists of two separate magnets, which, on the one hand, reduces the cost of production, and on the other hand, prevents interaction with relative rotation of the iron core and the magnet, this allowing the output of the current-carrying wires on both ends of the iron core without affecting the rotation of the iron core or magnet.

The unipolar generator rotation speed of the rotating shaft is 6000 rpm and frequency of AC 50Hz; two-pole generator rotation speed of the rotating shaft is 3000 rpm and the AC frequency of 50 Hz; four-pole generator rotation speed of the rotating shaft is 1500 rpm and the AC frequency of 50 Hz.

In order for the generator shown in Figure 1 - Figure 4, could generate three-phase sinusoidal alternating current for feeding to the network, the direction of the poles of the first magnet 8 and the second magnet 9 is the opposite, i.e, the direction of the magnetic lines of C the two opposite poles. If you need a full-wave current, the direction of the poles of the first magnet 8 and the second magnet 9 must be identical, i.e, the direction of lines of magnetic forces of the two poles must be identical.

Because the magnet is always attracted to the iron core, a number of external magnetic blocks 17 is located on the first rotary disk 2, as shown in figure 1 and Figure 3, to prevent deformation of the first rotary disc 2 under the action of external forces during the long service life of the generator. External magnetic blocks 17 are uniformly distributed on a circle with a rotating shaft 4 as a center. A number of internal magnetic blocks 18 are located on the holder of the iron cores 1 and uniformly distributed on a circle with a rotating shaft 4 as a center. The vertical distance between the outer magnetic blocks 17 and the rotary shaft 4 is equal to the distance between the internal magnetic blocks 18 and the rotating shaft 4. External magnetic blocks 17 and the internal magnetic blocks 18 and pole match, with the same poles facing each other.

Because the magnet is always attracted to the iron core, a number of external magnetic blocks 17 is located on the second rotary disc 3, to prevent deformation of the first bradauskas the disk 2 under the action of external forces during the long service life of the generator. External magnetic blocks 17 are uniformly distributed on a circle with a rotating shaft 4 as a center. A number of internal magnetic blocks 18 are located on the holder of the iron cores 3 and evenly distributed on a circle with a rotating shaft 4 as a center. The vertical distance between the outer magnetic blocks 17 and the rotary shaft 4 is equal to the distance between the internal magnetic blocks 18 and the rotating shaft 4. External magnetic blocks 17 and the internal magnetic blocks 18 and pole match, with the same poles facing each other.

The repelling force between the outer magnetic blocks 17 and the internal magnetic blocks can balance the attraction of the pole to the iron core, as well as to reduce the resistance to rotation when the generator.

To ensure the sealing action on the reservoir 19 for liquid first sealing plate 22 and the second sealing plate 23 and reduce the resistance of friction, as shown in figure 3 and Figure 4, the second sealing plate may have a circular design. The first sealing plate may also have a circular design. The first sealing plate 22 and the second sealing plate 23 can be combined respectively with the first rotary disk 2 and the second rotation is aushima disk 3.

The bearing 21, which may be a bearing Maglev, can be located between the rotating shaft 4 and the holder 1 iron cores to reduce friction.

Air is pumped away from a cylindrical body (vacuum). In the centre there is a shaft installed vertically to the axis of the cylinder, on which there is a unit of movable generators fixed. Under action of the centrifugal force, as the shaft untwists from the primary source of current, movable generators are lifted and fixed in a position perpendicular to the axis of the shaft, afterwards the primary source is switched off. Shaft inertia is used as an additional source of current, removed by a generator. After stop of the shaft each movable generator alternately starts lowering along a serrated arc, generating power as a result of its mechanical energy. A control unit monitors lowering of each movable generator and accordingly current at the output.

SUBSTANCE: invention is realised by generation of working voltage pulses in a stator winding (15) at the moment of approach of opposite magnetic poles of the stator (13), (14) and a rotor electromagnet (1). The magnetic field of the rotor electromagnet is generated by voltage pulses sent to the rotor winding from an outer source of power supply (4) via brushes (3) and contact semirings (2) only at the moments of approach of opposite magnetic poles of the rotor (1) and stator (2). At the moments when magnetic poles of the rotor and stator move away from each other, contact of brushes and rotor semirings is interrupted, and the magnetic field of the rotor disappears. And electromagnet forces that brake rotor rotation also disappear.

EFFECT: saving electric energy for a process to generate electric pulses with a power generator due to the fact that it is only used to supply to rotor electromagnets, and also by liquidation of electromagnetic forces braking rotor rotation at the moment when its magnetic pole moves away from a stator magnetic pole.

SUBSTANCE: in the proposed electromagnetic machine there is the second stage of excitation, which makes it possible to avoid generation of parasitizing EMF in windings of motive poles of the main stator when passed by the electromagnetic poles of the inductor. During rotation of the movable intermediate inductor (rotor) from an external motor, EMF will be induced in the active wires of the movable stator resulting in windings of the electromagnetic poles of the movable inductor. It is due to the fact that these wires will periodically cross now outgoing, now converging lines of magnetic field induction, developed by magnetic poles of permanent magnets of a fixed central inductor. Magnetic flows developed by currents in windings of the movable inductor piles increase due to their ferromagnetic cores µ times, which will penetrate active wires of the main fixed stator generator poles windings. As a result of electromagnetic induction EMF are induced, which will cause currents in windings of movable poles of the main fixed stator. The latter are polarised at the same time, their magnetic flows also increase µ times and start interacting positively with electromagnetic poles of the movable inductor. As a result each pole of the movable inductor along with its motion will always be exposed to a pair of positive forces, which will help the rotor to reach the nominal speed.

EFFECT: improved electromechanical characteristics of the electromagnetic machine with simultaneous increase of its efficiency.

As far as acyclic motors are manufactured (invented generators have reversibility), need for alternating current is no more actual. Future belongs to direct current. Mr. M. O. Dolivo-Dobrovolskiy, inventor of three-phase AC system, our compatriot (1861-1919) expressed his opinion on the above.
