Abstract

A static magnetic flux generator. The invention is different from the basic structure and the movement mode of the conventional generator, and the magnetic flux direction in the iron core are not periodically changed through the relative movement between the magnet and the iron core or between the iron core and the iron core, so that the coil surrounding the iron core induces the changed magnetic flux. The iron core shields the magnetic force line of the magnet in the air but does not influence the induction of the coil on the magnetic flux, so the prismatic resistance is not generated, the power generation efficiency is greatly improved, and the method is equivalent to directly extracting permanent magnetic energy in the generator to convert the permanent magnetic energy into electric energy.

Description

Static magnetic flux generator

Technical Field

The invention relates to a static magnetic flux generator, and belongs to the technical field of power generation in the new energy power generation technology, wherein permanent magnetic energy can be directly extracted and converted into electric energy, and other energy is rarely consumed.

Background

Since the electric generator appeared for more than one hundred years, the technology is constantly under innovation and perfection, and the perfect extraction of permanent magnetic energy is also the same. In the traditional generator, the magnetic flux and the magnetic flux direction in the iron core are periodically changed through the relative movement between the magnet and the iron core or between the iron core and the iron core, so that the lenz magnetic flux always hinders the movement, and the permanent magnet energy is converted into electric energy while a large amount of mechanical energy is consumed, namely the mechanical energy is converted into the electric energy. On one hand, as the permanent magnetic energy is wasted, people dig fossil fuel and nuclear fuel to exchange mechanical energy for the fuel and then convert the fossil fuel and the nuclear fuel into electric energy in order to obtain the electric energy, on the other hand, countless experts and scholars worry about as much as people worry about doing effort for improving the power generation efficiency, but still take steps and have little effect because the old method is already in poor end roads. Conventionally, a phenomenon has been ignored, that is, the movement of the coil relative to the iron core changes the magnetic flux and the magnetic flux direction in the coil without changing the magnetic flux and the magnetic flux direction in the iron core, so that the lenz magnetic flux of the electric energy is generated, the movement of the movement mechanism is hardly hindered, and although the improvement of the electric energy efficiency cannot be considered greatly, no attempt has been made.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: in the traditional generator, the magnetic flux and the direction of the magnetic flux in the iron core are periodically changed through the relative movement between the magnet and the iron core or between the iron core and the iron core, so that the prismatic magnetic flux always hinders the movement, more mechanical energy is consumed, the efficiency is reduced, the permanent magnetic energy cannot be directly extracted in the generator and converted into electric energy, and only the mechanical energy can be converted into the electric energy. The invention adopts the scheme that the coil moves relative to the iron core, and the prismatic magnetic flux can not generate prismatic force by utilizing the shielding effect of the iron core, thereby greatly improving the generating efficiency, which is equivalent to directly extracting permanent magnetic energy or extracting excited electric energy in a generator to convert the permanent magnetic energy or the excited electric energy into electric energy.

The technical scheme provided by the invention is that an iron core is made into the shapes of a plurality of straight plate bridges and bridge openings or the shapes of bridges and bridge openings with other shapes, magnetic fluxes of magnets or excitation coils flow through straight plate bridge bodies or bridge bodies through bridge piers and then return to the other pole of the adjacent bridge piers or return to the other pole of the other magnet, so that the directions of the magnetic fluxes in each adjacent straight plate bridge body or bridge body are opposite, the sizes and the directions of the magnetic fluxes in the bridge bodies are regularly distributed in an approximate square wave mode on the whole, but no magnetic flux exists in air above a bridge floor due to the shielding effect of the iron core, so that pancake coils on the bridge floor can induce the magnetic fluxes in the straight plate bridge bodies or bridge bodies in relative motion to generate electricity, and can not generate prismatic force in the air above the bridge floor, and the pancake coils can generate electricity without resistance relative to the bridge floor of the iron core.

A partial cross-sectional view of the straight bridge core is shown in fig. 3 (a) and fig. 3 (b).

The circular movement of the coil relative to the core, taking a pancake coil wound around two layers as an example, corresponds to the maximum magnetic flux in the coil in the conventional generator when the coil moves to the position of fig. 3 (b 1), corresponds to the change of the magnetic flux in the coil from the maximum to 0 when the coil moves from the position of fig. 3 (b 1) to the position of fig. 3 (b 2), and corresponds to the change of the magnetic flux in the coil from 0 to the opposite maximum when the coil moves from the position of fig. 3 (b 2) to the position of fig. 3 (b 3). The magnitude and direction of the magnetic flux in the coil thus exhibit periodic changes in relative motion, and an induced electromotive force is generated in the coil.

Because the iron core shields the magnetic flux of the magnet or the excitation coil scattered in the air around the pancake coil, the prismatic magnetic flux distributed around the pancake coil generated after the induced current is loaded cannot generate prismatic force. The Qilen-times magnetic flux passing through the shallow layer of the iron core also returns to the other pole of the other coil in the air, forms a loop and cannot reach the magnet, and only generates attraction force between the coil and the iron core. The flux into the core and the flux out of the core back into the air are the same and both appear as attractive forces. Even if the lenz magnetic flux penetrates through the iron core too much and directly acts with the magnet or the excitation coil, only the acting force between the iron core and the magnet or between the iron core and the excitation coil is the acting force, and the attraction force between the pancake coil and the iron core is still the same as the reason that no repulsive force exists between the coil and the iron core in the electromagnet during working. Therefore, the generator only needs to overcome the influence of large and small attractive force due to inconsistent depth of the iron core, and the resistance is very small, which is equivalent to directly converting the permanent magnetic energy or the excitation energy into the electric energy. Therefore, the technical problem that the rotor and the stator of the traditional generator always overcome the defect that the rotor and the stator of the traditional generator consume more mechanical energy and can not directly convert the permanent magnetic energy into electric energy in the relative motion process.

Two key components of the scheme are an iron core and a pancake coil, and the iron core and the pancake coil can be a rotor and a stator. When the pancake coil and the framework are used as rotors, voltage output wires need to be led out from the electric brushes.

The iron core is of a plate bridge structure. The iron core is embedded with a plurality of magnets, or the mode of adopting the excitation coil instead of the magnets is adopted, so that the magnitude and the direction of the static magnetic flux in the iron core slab bridge are regularly changed like positive and negative square waves in the relative movement direction of the iron core slab bridge and the coils. For a cylindrical generator, the shape of the plate bridge structure can be directly seen from fig. 4 (a); for a disc generator, the shape of the iron core is as shown in fig. 1 (a) and fig. 2, and the sectional shape of a partial unit is as shown in fig. 3.

The magnetizing direction of the magnet is arranged in the iron core in two ways, one is that the magnetizing direction of the magnet is perpendicular to the opposite surfaces of the iron core and the coil, for example, fig. 2 is a disc type perpendicular to each other; the other is that the magnetizing direction of the magnets is parallel or tangent to the opposite surfaces of the iron core and the coil, and when the magnetizing direction of the magnets is parallel or tangent to the opposite surfaces of the iron core and the coil, the polarities of the two adjacent magnets are opposite. As shown in fig. 1 (a), the magnetic core is of a disk-type parallel type, and no magnet is embedded in the magnetic core.

The generator iron core adopts a straight bridge and a hole mode, firstly, the magnet is far away from the pancake coil, and the influence of the reverse magnetic flux of the magnet is reduced (mainly for the type that the magnetic pole direction is parallel to the opposite surface of the iron core coil); secondly, the thickness of the iron core straight plate bridge is proper, so that the saturated or nearly saturated magnetic flux density is formed conveniently; an air channel is reserved, so that heat dissipation is facilitated; and fourthly, the magnetic flux in the air around the shielding coil is more thoroughly shielded, the redundant magnetic flux flows through the air in the bridge opening, and no magnetic flux exists outside the iron core.

The coil is a self-adhesive pancake coil, and a plurality of pancake coils are embedded in the pancake framework to serve as a rotor or a stator. The shape of the bobbin and the coil is a cylindrical surface type pancake shape for a cylindrical generator and a disc surface type pancake shape for a disc generator. Fig. 1 (c) shows the coil frame of the disc generator, the outer ring has 4 ears and screw holes for radial concentricity positioning, and a plurality of pancake coils are embedded in the outer ring, and two ends of each pancake coil are bent. The right side of the figure 1 (d) is the winding mode of a single pancake coil of the disc generator, the left side is the shape of the pancake coil, and the two ends are bent to induce more magnetic flux; the winding mode and the shape of the single pancake coil of the cylindrical generator are similar to those of the cylindrical generator, but the cylindrical generator is long in length and is in a curved surface shape in the width direction.

The structure of the cylindrical generator is shown in fig. 4 (a), an even number of magnets are arranged under the iron core bridge, or the magnet is excited under the bridge, so that the magnetic flux in the bridge body of the plate bridge in the circumferential motion direction is regularly distributed in the same direction as positive and negative square waves, and the pancake coils do circumferential motion relative to the bridge surface of the iron core plate bridge, thereby generating induced electromotive force. When the excitation type is adopted, the iron core can be used as a rotor, and the pancake coil can be used as a stator.

The structure of the disc type generator is shown in figure 4 (b), each set of magnet of the disc type generator can maintain two iron core disc surfaces, an iron core rotor or an iron core stator shown in figure 1 (a) or figure 2 is manufactured, a multistage structure is adopted, positioning rings are used for positioning between the stators, a shaft sleeve is used for positioning between the rotors, and the front side and the rear side of a pancake coil in the middle position can induce magnetic flux in the iron core during rotation, so that the energy density is improved.

The coil in fig. 1 (c) and 1 (d) is a pancake coil of a disk generator, and the portions of the two ends of the coil, which exceed the iron core, are bent into arc-shaped right angles.

The scheme of the coil comprises a scheme of bending a right angle and a scheme of not bending, and although both schemes can generate power, the bent scheme can induce more magnetic flux and has higher energy density due to the fact that the coil is in a half-surrounding state with respect to the iron core after being bent.

Since such a generator operates without resistance, it is necessary to provide a disk generator in a multistage structure to increase the power generation capacity.

Unlike an air-core coil generator, the generator induces the magnetic flux and the magnetic flux direction in the air by using the iron core as a medium, instead of inducing the magnetic flux and the magnetic flux direction in the air by using the air as a medium, so that the induced electromotive force induced by using the iron core as a medium is not in one order of magnitude (differs by a plurality of orders of magnitude) compared with that induced by using the air as a medium.

The attractive force between the lenz magnetic flux of the coil and the iron core can be processed by strengthening the bonding strength of the framework and offsetting the back and forth. Specifically, the pancake coil adopts a self-adhesive coil, the strength of the solidified glue is equivalent to that of the skeleton, the coil and the skeleton are firmly bonded, or the coil and the skeleton are integrally cast by high-strength glue, a supporting and fixing part is additionally arranged at the position where the size of the coil is larger than that of the iron core, so that the coil is clamped on the skeleton, and a plurality of thin ribs or very thin rib nets or ribs are additionally arranged between layers of the coil if necessary. When a cylindrical generator is used, two attractive forces with radial symmetry cancel each other out. When a disk-type multistage generator is adopted, each coil or iron core in the middle is subjected to front and back attractive forces, and the front and back attractive forces cancel each other when the air gaps are equal.

As to how to keep the air gap equal, two measures can be taken simultaneously at the time of assembly: the first is that one end of two ends of the shaft uses a thrust bearing or the thrust bearing and a radial bearing, and the other end uses the radial bearing; the second is that the axial force of all the rotors is intentionally unbalanced, and the end of the thrust bearing is attracted by a large force and the other end is attracted by a small force. Three methods are provided for making all rotors unbalanced in axial stress, one is to make the generator vertically run and make the axial stress unbalanced by the weight of the rotor, and the other is to make individual rotor or individual stator not generate electricity, so as to make the attraction force biased to one end; the three methods are that a set of rotor and stator of brushless motor is added on the shaft, and the axial thrust of the brushless motor is used to make the stress of the rotor unbalanced. After the brushless motor is additionally arranged, an external power machine is not needed.

In addition, there is a method of maintaining the air gap equal without using a thrust bearing: the rotor and the stator of the disc type brushless motor are additionally arranged on the rotating shaft of the generator, but the brushless motor generates axial thrust in the front direction and the rear direction, so that the whole rotor can be stabilized at a certain position and can not move. Radial bearings are used at two ends of the shaft, and bearing holes are made into through holes. This method also does not require an external power machine.

The most direct effect of the scheme is that the power generation efficiency is remarkably improved, the rotation resistance of the rotor is small, so that the disc type generator is generally made into a generator with a multi-stage rotor and a multi-stage stator and a relatively large power generation capacity, and the multi-stage disc type generator can induce magnetic lines of force in the iron core at the front side and the rear side of the coil, so that the effect of improving the energy density is achieved compared with a mode that the coil is wound around a salient pole of the iron core to enable the coil to be induced at only one side.

The specific implementation mode is as follows:

various generators can be manufactured according to the scheme of the invention. The generator of the preferred mode made by the inventor is explained below with reference to the drawings. The inventors hereby state their invention that the preferred embodiments are illustrative and not restrictive.

The preferred mode is a disk-type multistage generator.

The rotor is a magnet and an iron core, and each pair of magnets can maintain a front iron core disk and a rear iron core disk; the stator is a pancake coil and a framework.

The magnetizing direction of the magnet is arranged in the iron core in two ways, namely the magnetizing direction of the magnet is perpendicular to the opposite surfaces of the iron core and the coil, and the magnetizing direction of the magnet is parallel to or tangent to the opposite surfaces of the iron core and the coil. When parallel or tangential, the polarities of two adjacent magnets are opposite.

Fig. 1 (a) is a schematic view of an integral core with the magnetizing direction of the magnet parallel to the opposite surface, and the magnet is not embedded in the core. Fig. 1 (b) is a schematic diagram of a semi-open core with the magnetizing direction of the magnet parallel to the opposite surface, in which a part of the magnet is placed, and the magnetic pole direction can be seen. The iron cores can see the structure of a straight plate bridge on a partial section structure, and the bridge pier is in a trapezoid shape or other shapes, as shown in figure 3 (a).

Referring to fig. 2, a schematic diagram of a core and a magnet with their magnetic poles perpendicular to the opposite surfaces is shown, and the core cannot be used in a single body, and a manner of sandwiching the magnet between the upper and lower halves of the core and combining them together can be adopted. Such a core is also required to have a partial cross-sectional structure of a straight plate bridge and a bridge pier as shown in fig. 3 (b), and the bridge pier is trapezoidal. When the strength of the magnet is stronger, the height of the pier can be properly increased, so that the shielding is more effective; when the strength of the magnet is weaker, the area of the magnet can be increased and the length of the slab bridge can be increased appropriately, so that the saturation value of the magnetic flux of the slab bridge can be appropriate.

The edge of the magnet of the iron core can be slightly higher than the plane of the magnet, so that the magnet is embedded into the iron core and treated like the iron cores at two sides of the width of the magnet in fig. 3 (b), and the iron cores at two edges of the radial length of the magnet are also treated, thereby facilitating the magnetic flux of the magnet to completely go through the iron core channel.

The magnetic flux of the magnet, namely the product of the strength of the magnet and the surface area perpendicular to the magnetic field direction, must make the magnetic flux density passing through the plate bridge reach saturation or close to saturation, when the saturation or close to saturation, the magnetic flux density near the upper surface and near the lower surface of the plate bridge are approximately equal, which is beneficial to the induction of the pancake coil to the magnetic flux and the improvement of the energy density.

Because the bridge opening is arranged below the straight bridge, the part of the iron core lining connected with the shaft can be made into a small-inclination impeller shape, so that ventilation is facilitated, and the wind resistance is reduced. And drilling a vent hole of the annular hoop of the outer ring of the iron core slightly larger. The annular hoops do not have to cover the entire width of the iron core, but only the bridge piers and the magnets.

The stator of the pancake coil motor adopts a stator coil framework to embed a pancake coil into the stator coil framework, or the coil and the framework can be poured into a whole by high-strength glue, and the thickness of the self-adhesion pancake coil is the same as that of the stator coil framework. The arc-shaped rotary part of the coil, the size of which exceeds the rotor core, is bent into an arc-shaped right angle according to the diameter of the rotor, and the coil is fixed on the framework by using the supporting and fixing piece. The outer lane of skeleton has 4 screw holes, and the screw hole is surrounded by 4 ears for radial concentricity's location and circumference location. When multistage generator is whole when assembling, the axial distance between skeleton and the skeleton is fixed a position by the holding ring, also has 4 axial screw holes the same with the skeleton on the holding ring, can also arrange some radial holes at intervals in addition and be used for observing the air gap. Each positioning ring can also be replaced by 4 small cylinders with screw holes.

The width of the coil is ensured to ensure that the left side and the right side of the coil can induce the maximum magnetic fluxes with opposite directions. No matter which iron core is adopted in the magnetizing direction of the magnet, the number of the coils can be equal to half of the number of the magnets, and can also be equal to the number of the magnets. Induced electromotive force and energy efficiency generated by the two coil numbers are not greatly different, but the small and narrow coil can be bonded more firmly. In the preferred embodiment, the number of coils is equal to the number of magnets, i.e., 12 magnets per core rotor disk and 12 coils per skeleton stator disk.

Fig. 1 (c) and 1 (d) show a coil shape in which two semicircular shapes sandwich a rectangle. However, in actual manufacturing, the enameled wire can be designed to be a trapezoid sandwiched between two semi-circles with different radiuses, and two waists of the trapezoid are overlapped with radial lines, so that the enameled wire is perpendicular to the magnetic flux direction, the attraction force between two adjacent pancake coils is relatively even, and the inconvenience is that the end with a larger radius is possibly bonded with a lower degree or the hole in the middle of the coil is larger.

The winding method of the coil is to wind the coil into a long and narrow pancake shape and to wind the coil layer by layer. The first layer is from outside to inside, and then winds the second layer from inside to outside, the number of layers of the coil is double, and the end of the enameled wire of the coil is outside. The length of the coil is slightly longer than that of the magnet, specifically, each end is at least about 0.5 times longer than half of the maximum width of the coil, and the part exceeding (including being larger than and smaller than) the diameter of the iron core is bent into an arc right angle, so that the iron core is in a semi-surrounding state when the iron core rotates relatively. Half of the thickness is bent upwards and half of the thickness is bent downwards. Fig. 1 (c) is an overall schematic diagram of the stator coil and the frame, and fig. 1 (d) is a left side schematic diagram of a shape of a single pancake coil. The right diagram of fig. 1 (d) is a schematic diagram of the winding manner, and the right diagram only shows the winding manner and the bending manner of the coil of the first layer, and other layers are similar.

Fig. 4 (b) is a schematic diagram of the overall structure of a multi-stage disk generator, which includes 4 rotor core disks as shown in fig. 2 and 5 stator coils and frameworks as shown in fig. 1 (c), wherein 4 rotor cores are lined on a shaft, an annular hoop only covering a magnet and a pier is sleeved on an outer sleeve of the core, and the coil frameworks are connected with a positioning ring and front and rear end covers by 4 long screws. The pancake coils in the middle 3 frameworks can respectively induce the magnetic flux in the front iron core and the rear iron core. The frame and the coil on the rightmost side are not connected and are in a vacant state, so that the attraction force applied to the whole rotor core in the left direction is large when the rotor core generates electricity, meanwhile, the thrust bearing and the radial bearing are used on the left side of the shaft, the radial bearing is used on the right side of the shaft, the stability of the axial position and the equal air gap are maintained, and therefore the attraction force applied to the 3 middle stator coils and the frame is offset front and back.

The stator and the stator of the generator are positioned by a positioning ring, and the rotor are positioned by a shaft sleeve; besides 4 axial screw holes which are the same as the coil framework, the positioning ring is also provided with a plurality of observation holes which are distributed at intervals in the radial direction and used for observing air gaps, and each positioning ring can also be replaced by 4 small cylinders with screw holes; the end cover on the left side can be made into a form with a base, so that the end cover can be vertically arranged and installed conveniently, can be vertically or horizontally arranged during operation, and when the end cover is operated in a vertical mode, a stator without a coil on the rightmost framework (positioned on the uppermost part during vertical operation) can be changed into a stator with a coil on the framework; 4 long screws penetrating through the framework, the positioning ring and the front end cover and the rear end cover are only seen at two ends and nuts on the end covers in the figure 4 (b) because the positions are half at 7 o 'clock and half at 10 o' clock, and 4 proper gaps are formed at the nuts on the base of the end cover on the left side for the nuts; in addition, an air gap adjusting device (such as a worm gear and a worm) can be arranged on the left end cover to carry out micro-adjustment on the thrust bearing so as to ensure that the air gap of the thrust bearing is equal after the thrust bearing is worn for a long time.

The description of the present invention may be incomplete and several variations may be made without departing from the inventive concept, which is intended to be infringement.
