Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of mechanical engineering, is used for improving the mechanical motion efficiency produced by the interaction of permanent magnet magnetic field in rotor stator system. The utility model can improve the acquisition efficiency of energy (including electric energy), meet the civil, industrial and public demand. BACKGROUND

[0002] Known "permanent magnet motor" device, Russian patent No. 2177201, is composed of non-magnetic housing, two spherical permanent magnets, a cubic permanent magnet slider, coil and independent power supply.

[0003] The disadvantage of the known device is the complex structure and low efficiency. Many rotating and friction surfaces complicate the structure, while four coils working in cycles require a large amount of electric energy.

[0004] Known "magnetic engine", Russian patent No. 34826, the structure includes a non-magnetic housing, two same-pole opposite magnets, a connecting rod, a crankshaft and a movable ferromagnetic shield that interrupts the magnetic field interaction of permanent magnets through reciprocating motion.

[0005] The disadvantage of the known device is the lack of material that can properly shield or transform the permanent magnet magnetic field, so the attraction between the ferromagnetic shield and the rotor permanent magnet will bring the device to an equilibrium state and stop the mechanical movement. SUMMARY

[0006] The utility model aims to improve the efficiency of mechanical movement through the periodic interaction between the magnetic field of the rotor permanent magnet and the magnetic field of the stator permanent magnet. These magnetic fields have the properties of connection, disconnection, restoring force, shape, direction and symmetry. The utility model belongs to the field of mechanical engineering, is used for improving the acquisition efficiency of energy (including electric energy), meet the civil, industrial and public demand.

[0007] The technical effect of the utility model is to improve the efficiency of mechanical movement, especially the rotation efficiency of the rotor, which is achieved by superimposing the centrifugal force of the rotor. The source of this centrifugal force is the force that restores the partial symmetry interaction of the stator and rotor permanent magnet magnetic fields, as well as the force acting in the direction of rotor rotation generated by the connection of the permanent magnet magnetic field. The periodic interaction of the rotor and stator magnetic fields is achieved due to the properties of the magnetic field of the magnet that can continuously restore its shape, strength and direction after the interaction with the magnetic field of other magnets stops. The specification provides a solution to improve the efficiency of rotor mechanical movement using gravity, which is generated due to the offset of the rotor center of gravity and the inclination of the rotor rotation plane relative to the earth's surface. In order to increase the interaction of the stator and rotor magnetic fields, the specification proposes a solution, i.e. placing the stator magnet inclined to the rotation plane of the rotor magnet.

[0008] The utility model is used for improving the mechanical movement efficiency of permanent magnet magnetic field interaction in rotor-stator system, characterized in that the device includes a rotor rotating around its own axis, permanent magnets are fixed on the cylindrical outer surface of the rotor, the magnetic field of these permanent magnets interacts with the magnetic field of the stator magnets fixed on the base and connected through elastic connecting pieces. In order to improve the mechanical movement efficiency of the rotor-stator system, the force generated by the interaction of the stator and rotor permanent magnet magnetic field is converted into the centrifugal force of the rotor. The characteristics of the magnetic field include connection, disconnection, recovery direction, force, symmetry and the shape of the magnetic field part before, during and after interaction with other magnets, which together create the periodic operation of the device. These characteristics of the permanent magnet can generate force acting on the movement direction of the rotor and the centrifugal force of the rotor. When the rotor magnet is close to the stator magnet, an attractive force along the rotation direction of the rotor will be generated between the magnets, thereby driving the rotation of the cylindrical outer surface of the rotor. When the rotor magnet moves along the neutral line of the stator magnet, due to the offset of the movement track of the neutral line of the rotor magnet relative to the neutral line of the stator magnet, a force will be generated between the magnetic fields of the rotor magnet and the stator magnet, which recovers the symmetry interaction of the magnetic field part thereof. Since the rotor magnet is firmly fixed on its cylindrical surface, this force is the source of the centrifugal movement of the rotor on one hand and the force that increases the resistance of the elastic connecting piece of the stator magnet on the other hand. During the rotation of the cylindrical outer surface of the rotor, the stator magnet alternately interacts with one or two rotor magnets, thereby increasing and decreasing the force acting on the elastic connecting piece of the stator magnet, which will generate an asymmetric interaction with the magnetic field of the rotor magnet and prevent the interacting magnets from reaching a force balance state. Therefore, the rotation efficiency of the rotor is improved. In the device for improving the mechanical movement efficiency of the rotor-stator system by utilizing the interaction of permanent magnet magnetic fields, the sources of improving the movement efficiency of the rotor include the connection force of the magnetic field of the magnet, the force that recovers the symmetric interaction of the magnetic field part of the magnet, and the characteristics of the magnet that continuously recover the shape, strength and direction of its magnetic field after the interaction with the magnetic field of another magnet stops.

Detailed Implementation

[0021] The working principle of the device that improves the mechanical motion efficiency of the rotor-stator system by utilizing the interaction of permanent magnet magnetic fields is as follows ( Figure 1 As shown). An external force F5 acts on the cylindrical outer surface (3) of the rotor. The device moves along the D direction. The rotor is balanced by a counterweight (17), the rotor center of gravity (16) coincides with the shaft (2), and the stator is provided with multiple magnets (5, 5.1, 5.2, 5.3) along the movement trajectory of the rotor magnets. When the rotor magnet (4.1)( Figure 4 As shown, when the rotor magnet (5) approaches the stator magnet, due to the coupling of the magnetic fields of the rotor magnet and the stator magnet, a force F1 acting in the direction of rotor rotation will be generated on the rotor magnet. Figure 3 The image shows the magnetic fields of the rotor magnet (9.1) and stator magnet (9.2) before their interaction. Figure 4Fig. 9.1 shows the interaction of the magnetic field of the rotor magnet (9.1) with the magnetic field of the stator magnet (9.2), the result of which is the coupling of the magnetic fields (9.3) and the generation of the force Fl. The source of the force Fl is the coupling process of the magnetic fields of the rotor magnet and the stator magnet. When the rotor magnet moves along the neutral line of the stator magnet (shown in Figure 5 Fig. 9.1), a force F3 is generated between the magnetic fields due to the relative displacement of the neutral line of the rotor permanent magnet (10) and the neutral line of the stator permanent magnet (11), which serves to restore the symmetrical interaction of the magnetic field portions and to bring the neutral lines into coincidence, while the force F6 changes the resistance of the stator magnet fixing (7). The force F3 directed from the rotor magnet (4.1) to the stator magnet (5) is the source of the centrifugal force F of the rotor. The source of the force F3 is the force that attempts to restore the symmetrical interaction of the magnetic field portions of the rotor magnet (4.1), which is fixed to the rotor cylindrical outer surface (3) by a rigid connection (6), and the stator (5), which is fixed to the device base (1) by an elastic connection, which generates a resistance (7). The continued rotation of the rotor cylindrical outer surface (3) causes the magnetic field of the stator magnet (5) to begin to interact with the magnetic field of the rotor magnet (4.2), generating a force Fl acting in the direction of rotation of the rotor and a force F2 acting in the opposite direction of rotation of the rotor (this force exists between the magnetic field of the stator magnet (5) and the magnetic field of the rotor magnet (4.1)). The rotor permanent magnets (4.2 and 4.3) interact with their magnetic fields in a similar manner to the magnetic field of the stator magnet (5). When the rotor magnet moves along the neutral line of the stator magnet, a force F3 acts on the rotor magnet. The length L2 of the neutral line of the stator magnet (shown in Figure 8 Fig. 9.1) is greater than the distance L1 between the rigid connections of the rotor magnet, so the force F2 on the magnet (4.1) is compensated by the force Fl on the magnet (4.2), and the force F2 on the magnet (4.2) is compensated by the force Fl on the magnet (4.3). In Figure 7 this way, the elastic connection (7) of the stator is subjected to double the force F3 when the magnetic fields of the rotor magnets (4.1 and 4.2) and (4.2 and 4.3) interact with the magnetic field of the stator magnet (5), while the force F3 is reduced when the magnetic field of the stator magnet (5) interacts with the magnetic field of one rotor magnet, for example (4.2), which causes the force (F6) of the elastic connection of the stator to change. Thus, during the rotation of the rotor cylindrical outer surface (3), an asymmetrical interaction between the magnetic fields of the rotor magnets and the stator magnets is generated, which prevents the magnets in the device from reaching a state of equilibrium of their interaction and increases the efficiency of the movement of the rotor. In order to increase the interaction between the magnetic fields of the rotor magnets and the stator magnets, the neutral line of the stator magnet can be placed inclined with respect to the plane of rotation of the rotor magnets (see Figure 6). Due to the three-dimensional nature of the magnetic field of the permanent magnets, the inclination angle of the stator magnet neutral line (15) with respect to the rotor magnet rotation plane (13) increases the amount of interaction between the magnetic field of the rotor magnet (4.1) and the magnetic field of the stator magnet (5) compared to the case where the neutral line of the stator magnet (5) is perpendicular to the rotor magnet rotation plane (13). In order to increase the asymmetric interaction between the magnetic field of the rotor magnet and the magnetic field of the stator magnet and to prevent the device from reaching an equilibrium state (see Figure 7 ), the stator connector (7) applies an overload force F7, while the stator additional fulcrum (8) can have a resistance and form a first, second or third class lever. The stator magnet (5) Figure 9 ) is located within the projection (12) of the rotor magnet trajectory. The stator magnet neutral line Figure 9 ) can have a different distance from the rotation axis: L3 < L4. In this case, the stator magnet neutral line forms an angle (14) with respect to the projection of the rotor magnet (4.1, 4.2, 4.3) neutral line trajectory, which increases the asymmetry of the interaction between the magnetic fields of the rotor magnet and the stator magnet, since the intensity of the magnetic field increases along the magnet pole head direction and decreases along the neutral line direction. The formula for calculating the rotor centrifugal force F is: F = 3(F1+F2+F3)+F5. The rotor magnet (4.1, 4.2, 4.3) interacts with the other stator magnets (5.1, 5.2, 5.3) in a similar way. Therefore, the magnetic fields of the rotor magnet and the stator magnet interact periodically, resulting in a rotor centrifugal force that increases the mechanical motion efficiency of the rotor-stator system. Figure 1a and 1b shows a device scheme where the rotor magnets (4) and the stator magnets (5) are arranged symmetrically with respect to the rotation axis (2).

[0022] In Figure 2 , a scheme is presented for increasing the mechanical motion efficiency of the stator-rotor system by periodic interaction of the magnetic fields of the permanent magnets and by using the gravitational force F4. In this scheme, the rotor center of gravity (16) does not coincide with the rotation axis (2). When the rotor center of gravity (16) moves from the rotor rotation maximum point (18) to the minimum point (19), the gravitational force F4 acts on the rotor cylindrical outer surface. The rotor acquires acceleration, so when the center of gravity (16) passes the rotor rotation minimum point (19), the rotor center of gravity (16) moves from the minimum point (19) to the maximum point (18) due to inertia. According to the law of conservation of energy, the rotor center of gravity (16) cannot reach the rotation maximum point (18). At this position, the magnetic field of the stator magnet (5) acts on the magnetic field of the rotor magnet (4.1) Figure 4 ). The stator magnet and the rotor magnet further interact in a similar way to the scheme described above. The formula for calculating the rotor centrifugal force F is: F = 3(F1+F2+F3)+F4+F5.

[0023] The device base (1), the rotor cylindrical outer surface (3), the stator magnet fixing (7), the rotor counterweight (17) are made of materials that do not interact or weakly interact with the magnetic field of the permanent magnets.

[0024] The device can be designed so that the interacting magnet groups are located at different distances from the rotation axis. The number of interacting magnet groups of the rotor and the stator can be different, the magnets can interact with their magnetic field simultaneously or alternately.

[0025] The energy generated by increasing the mechanical movement efficiency of the rotor can be transmitted in any known way, including through a soft or rigid connection with a reducer or generator. The magnetic field of the rotor magnets can also be used to generate an induced current. For this purpose, the winding of an electric generator is placed on the trajectory of the movement of the rotor magnets so that an induced current is generated when intersecting the magnetic field of the rotor magnets.

[0026] Increasing the mechanical movement efficiency of the rotor-stator system by interaction with the magnetic field of the permanent magnets has been verified by practical experiments. The experimental device was manufactured according to the design Figure 2 The base of the device (1) was made of stainless steel AISI 304, the rotor rotation axis (2) was a free rotating bushing fixed on the base of the device. The rotor cylindrical outer surface (3) was made of aluminum, with a diameter of 420 mm. The rotor permanent magnets: 20 x 40 mm neodymium magnet rods, weight 90 g, total 3. The stator permanent magnets: 75 x 20 x 5 mm neodymium magnet rectangular blocks. Additional counterweight: lead blocks with a total weight of 160 g. In order to obtain the same size external force in the experiment, a device was installed at the rigid connection of the rotor magnets (4.2) (coinciding with the rotor center of gravity (16)) that fixed the additional counterweight on the rotor cylindrical outer surface during the movement of the rotor center of gravity from the rotation highest point (18) to the lowest point (19). At the lowest point of the rotor rotation (19), the additional counterweight fell off the rotor cylindrical outer surface under the action of its own gravity. In the experiment, the rotor cylindrical outer surface was inclined at an angle of 20 degrees relative to the surface of the Earth. On it, 3 permanent magnets of neodymium were installed, the south pole of which was directed to the rotation axis. The distance from the rotor magnet neutral line to the rotation axis was 235 mm. The distance between the rigid connections of the rotor magnets was 60 mm. The rotor center of gravity (16) was located at the rigid connection of the rotor magnets (4.2). The stator magnets were located at the rotation highest point (18). The stator magnet fixing was made of glass fiber elastic material. The north pole of the stator magnets was directed to the rotation axis. The distance from the stator magnet neutral line to the rotation axis was 245 mm.

[0027] The experiment was divided into two parts. In the first part, the stator magnets were missing. The additional weights were placed at the center of gravity (16) on the cylindrical outer surface of the rotor. The center of gravity of the rotor was offset by 45 degrees relative to the highest point of rotation (18) towards the direction of rotation. In this position, the rotor started to move. At the lowest point of the rotor (19), the additional weights were separated. The rotor gained enough force to overcome the highest point of rotation (18) and complete a rotation. In the second rotation, due to the law of conservation of energy, the center of gravity of the rotor could not reach the highest point of rotation (18), so the rotor moved in the opposite direction. Thus, the rotor completed one rotation.

[0028] In the second part of the experiment, the stator magnets were placed in the above-mentioned manner at the highest point of rotation (18) of the rotor along the direction of movement of the rotor magnets. Similar to the first part of the experiment, the additional weights were placed on the cylindrical surface at the center of gravity of the rotor (16). The center of gravity of the rotor was offset by 45 degrees relative to the highest point of rotation (18) towards the direction of rotation. In this position, the rotor started to move. At the lowest point of the rotor (19), the additional weights were separated. The rotor gained enough force to overcome the highest point of rotation (18) and complete three rotations. In the fourth rotation, due to the law of conservation of energy, the center of gravity of the rotor could not reach the highest point of rotation (18), so the rotor moved in the opposite direction. Thus, the rotor completed three rotations. The comparison of the experimental results showed that in this case, the efficiency of the rotor-stator system (under the action of gravity) was at least three times higher.

[0029] The experiment was repeated 75 times, and each time the same results were obtained, which actually proved the claimed technical effect, i.e. the improvement of the efficiency of the rotor-stator system through the interaction of the magnetic fields of permanent magnets.
