Description

[0001] summary

[0002] This invention discloses a device for achieving power output by controlling the magnetic circuit of a permanent magnet, belonging to the field of power machinery. Based on the principle of magnetic field interaction, this device uses gear transmission combined with a magnetic conductor to control the permanent magnet's magnetic circuit, overcoming the technical shortcomings of traditional power machinery (internal combustion engines have high energy consumption and severe pollution; electric motors rely on continuous external energy) and existing magnetic motors (low energy conversion efficiency and unstable operation). Its core structure includes an outer magnetic base (stator), an inner magnetic base (rotor), a magnetic circuit control gearbox, and a magnetic chamber. Utilizing the repulsive and attractive properties of like poles and opposite poles of permanent magnets, gear transmission controls the rotation of the permanent magnet to dynamically adjust the magnetic field orientation, forming a continuous torque-driven rotation. This device requires no continuous external energy input (starting requires initial external force), and features high efficiency, stability, and wide applicability, making it suitable for industrial power, power generation equipment, and new energy transportation. Technical Field

[0003] This invention relates to the field of power machinery, specifically a magnetic power machinery designed based on the principle of magnetic field interaction, which is applicable to scenarios such as industrial power supply, power generation equipment, and new energy transportation vehicles, providing a new power solution. Background Art

[0004] Traditional power machinery has significant drawbacks: internal combustion engines consume a lot of energy and pollute the environment; electric motors rely on continuous external energy input, limiting their application in scenarios with unstable energy sources. While existing magnetic motor technology attempts to break free from dependence on traditional energy sources, its unreasonable magnetic force distribution and low energy conversion efficiency make it difficult to achieve continuous and stable operation, thus failing to meet practical application requirements.

[0005] This invention addresses the aforementioned technical deficiencies by using a gear-driven magnetic conductor combined with a powerful permanent magnet to control the magnetic circuit drive mechanism, providing a high-efficiency, stable power output device that does not rely on continuous external energy input. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] In response to the problems of high energy consumption, serious pollution, and dependence on external energy in traditional power machinery, as well as the low energy conversion efficiency and unstable operation of existing magnetic motors, this invention aims to provide a device that achieves efficient and stable power output by controlling the magnetic circuit of a permanent magnet, without the need for continuous input of external energy.

[0008] (2) Technical solution

[0009] 1. Structural Composition

[0010] The outer magnetic base (stator) (41) comprises an annular base and an array of N uniformly distributed outer magnetic chambers (42). Each outer magnetic chamber (42) is surrounded by an outer magnetic chamber conductor (43) (such as silicon steel) and an outer magnetic chamber permanent magnet (45) (such as neodymium iron boron magnet). The outer magnetic chamber (42) is disconnected from the inner magnetic chamber (32) by the outer magnetic chamber conductor (43) which is coupled to the inner magnetic chamber (32), and is sealed by an outer magnetic chamber non-conducting conductor (44). The outer magnetic chamber permanent magnet (45) is radially magnetized and connected in the middle by an outer magnetic chamber permanent magnet shaft (13), and supported by an outer magnetic chamber conductor (43) through an outer permanent magnet bearing (04); the outer magnetic chamber permanent magnet shaft (13) is also connected to the outer magnetic chamber top gear (12). The polarities of the outer magnetic chamber permanent magnets (45) of adjacent outer magnetic chambers (42) are arranged according to the corresponding rotation angle.

[0011] οInner Magnetic Base (Rotor) (31): The central rotating shaft (21) connects to the radial inner magnetic chambers (32). The inner magnetic chamber permanent magnet shaft (17) of the inner magnetic chamber (32) is supported by the inner magnetic base (31) through the inner permanent magnet bearing (02) and is rigidly connected to the inner magnetic chamber top gear (15). The inner magnetic chamber top gear (15) meshes with the speed-changing gear (16), and the speed-changing gear shaft (10) of the speed-changing gear (16) is fixed between the inner magnetic base top gear (18) and the inner magnetic base (31) through the bearing. The central rotating shaft (21) is connected to the housing (01) through the rotating shaft bearing (03) to realize external power output. The inner magnetic base (31) and the outer magnetic base (41) can serve as the rotor and stator for each other, improving application flexibility.

[0012] The magnetic circuit control gearbox (11) consists of: each outer magnetic chamber top gear (12) of the outer magnetic chamber (42) meshing with the inner magnetic base top gear (18) fixed on the top of the inner magnetic chamber (32); each inner magnetic chamber top gear (15) of the inner magnetic chamber (32) meshing with the speed-changing gear (16), which in turn meshes with the gear ring (14) fixed on the outer magnetic base (41). The magnetic circuit control gearbox (11) can be replaced by an electrical control system to adapt to different scenarios.

[0013] The magnetic chamber consists of an inner magnetic chamber (32) and an outer magnetic chamber (42), both of which are made of high-permeability materials (such as silicon steel) and are divided into two halves to surround the permanent magnets (35)(45) (such as neodymium iron boron and samarium cobalt permanent magnets). The magnetic conductors (33)(43) on the outside of the permanent magnets (35)(45) are disconnected and connected by non-magnetic conductors (34)(44). The width and thickness of the non-magnetic conductors (34)(44) are matched according to the magnetic field strength of the permanent magnets. When the two poles of the permanent magnets (35)(45) are perpendicular to the cross-section, they exhibit magnetism; when they are parallel, they do not exhibit magnetism. A 90-degree rotation can switch between the magnetized and non-magnetized states. A 360-degree rotation goes through a complete cycle of "S pole magnetization → non-magnetization → N pole magnetization → non-magnetization".

[0014] 1. Working principle

[0015] The device utilizes the principle of like poles repulsion and unlike poles attraction between permanent magnets (45)(35) in the outer magnetic chamber (42) and the inner magnetic chamber (32) to drive the permanent magnets (35)(45) to rotate in real time through gearbox transmission, thereby changing the magnetic field orientation and forming a continuous torque to drive the magnetic base (31)(41) to rotate.

[0016] When the outer magnetic chamber (42) rotates 45 degrees relative to the inner magnetic chamber (32), the gear meshing action drives the permanent magnets (35)(45) to rotate 90 degrees, changing from a magnetically active state to a non-magnetically active state. The permanent magnets (35)(45) rotate 360 ​​degrees to complete one magnetic field cycle. During operation, the interaction force between the outer and inner magnetic chambers is always greater than the force consumed by the magnetic circuit control. After applying an initial external force at startup, continuous and stable operation without external energy input can be achieved.

[0017] (3) Beneficial effects

[0018] 1. The gear transmission constrains the magnetic circuit, resulting in stable device performance, minimal impact from environmental climate, and a wide range of applications;

[0019] 2. No external energy input is required; the closed-loop control magnetic circuit reduces magnetic leakage loss and improves energy conversion efficiency.

[0020] 3. It can be replaced with an electrical control magnetic circuit, resulting in a smaller device size, more flexible applications, and adaptability to different spatial scenarios;

[0021] 4. The inner and outer magnetic bases can serve as rotor and stator for each other, improving application flexibility. Attached Figure Description

Detailed Implementation

[0032] The following details the assembly and operation process of the device, in conjunction with component markings:

[0033] 1. Magnetic chamber assembly

[0034] Inner magnetic chamber (32): The radially magnetized inner magnetic chamber permanent magnet (35) (with inner magnetic chamber permanent magnet shaft 17) is installed in the space half surrounded by the inner magnetic chamber magnetic conductor (33), and the disconnection of the magnetic conductor (33) is connected by the inner magnetic chamber non-magnetic conductor (34); the inner magnetic chamber permanent magnet shaft (17) is connected to the inner magnetic chamber magnetic conductor (33) through the inner permanent magnet bearing (02) to form a complete inner magnetic chamber (32).

[0035] οOuter magnetic chamber (42): The radially magnetized outer magnetic chamber permanent magnet (45) (with outer magnetic chamber permanent magnet shaft 13) is installed in the space half-enclosed by the outer magnetic chamber magnetic conductor (43), and the disconnection of the magnetic conductor (43) is connected by the outer magnetic chamber non-magnetic conductor (44); the outer magnetic chamber permanent magnet shaft (13) is connected to the outer magnetic chamber magnetic conductor (43) through the outer permanent magnet bearing (04) to form a complete outer magnetic chamber (42).

[0036] 1. Magnet polarity arrangement and base fixation

[0037] The inner magnetic chamber (32) is fixed radially to the inner magnetic base (31), and the outer magnetic chamber (42) is fixed in a ring array to the ring base of the outer magnetic base (41); the permanent magnets (35) (45) of the adjacent magnetic chambers are arranged alternately in four directions: "NS polarity parallel, perpendicular, SN polarity parallel, perpendicular" to ensure that the magnetic field is radially uniformly distributed.

[0038] 2. Initial State Adjustment

[0039] The permanent magnets (45) of the outer magnetic chamber (42) and the permanent magnets (35) of the inner magnetic chamber (32) are adjusted to be in a state of opposite poles (such as N pole to N pole), and the repulsive force of the same poles is used to provide initial power for starting.

[0040] 3. Power take-off shaft connection

[0041] The center of the inner magnetic base (31) is rigidly connected to the rotating shaft (21), and the rotating shaft (21) is connected to the housing (01) through the rotating shaft bearing (03) to ensure that the power is output to the outside through the rotating shaft (21).

[0042] 4. Assembly of the magnetic circuit control gearbox

[0043] ο External magnetic chamber transmission: The top end of the permanent magnet shaft (13) of the external magnetic chamber is connected to the top gear (12) of the external magnetic chamber. The top gear (12) of the external magnetic chamber meshes with the top gear (18) of the inner magnetic seat (the number of teeth is twice that of the top gear 12 of the external magnetic chamber) to form the self-rotation transmission structure of the permanent magnet (45) of the external magnetic chamber.

[0044] ο Inner magnetic chamber transmission: The top of the permanent magnet shaft (17) of the inner magnetic chamber is connected to the inner magnetic chamber top gear (15), which meshes with the speed-changing gear (16) (the number of teeth is equal to the number of teeth of the inner magnetic chamber top gear, which is twice the number of teeth of the coaxial pinion); the speed-changing gear (16) is fixed between the inner magnetic seat top gear (18) and the inner magnetic seat (31) through the speed-changing gear shaft (10), and meshes with the gear ring (14) fixed on the outer magnetic seat (41), forming the self-rotation transmission structure of the permanent magnet (35) of the inner magnetic chamber. The above transmission system together constitutes the magnetic circuit control gearbox (11).

[0045] 1. Start-up and continuous operation

[0046] ο Start-up: By applying an initial torque externally (such as rotating the rotating shaft 21), the inner magnetic base (31) and the outer magnetic base (41) rotate relative to each other, and the magnetic chambers (32) and (42) change from "non-magnetic" to "like poles repel each other" or "opposite poles attract each other". The gear transmission drives the permanent magnets (35) and (45) to rotate and adjust the direction of the magnetic field, so that the resultant force drives the device to start.

[0047] οContinuous operation: When the outer magnetic base (41) rotates 45 degrees relative to the inner magnetic base (31), the gear meshing drives the permanent magnet (35)(45) to rotate 90 degrees, and the relative inner and outer magnetic chambers (32)(42) turn into a "non-magnetic" state; when the rotation continues to the offset position, the permanent magnet becomes "magnetic" again, forming a new repulsive / attractive force with the adjacent magnetic chamber, and continues to drive the rotation.

[0048] οStability assurance: When the inner and outer magnetic chambers are at their maximum phase angle, the permanent magnets (35)(45) exhibit the strongest magnetism, providing the maximum driving force; the magnetic force is evenly distributed during periodic rotation, and combined with the precise control of gear transmission, the output speed of the rotating shaft (21) is stable.

[0049] Through the aforementioned structure and operating mechanism, this device achieves efficient energy conversion under closed-loop magnetic circuit control, enabling stable operation without the need for continuous external power supply, and is suitable for various power demand scenarios.

[0050] Example 1: Device suitable for micro-power generation equipment

[0051] 1. Structural Composition

[0052] The outer magnetic base (41) is made of high-strength plastic material with a diameter of 5-10 cm. Six outer magnetic chambers (42) are evenly distributed on the outer magnetic base (41) to form an array structure.

[0053] ●Outer magnetic chamber (42): The outer magnetic chamber permanent magnet (45) is surrounded by an outer magnetic chamber conductor (43), which is made of silicon steel. The outer magnetic chamber conductor (43) is disconnected from the inner magnetic chamber (32) at the coupling position. The disconnection is sealed by an outer magnetic chamber non-conductive material (44), which is made of polytetrafluoroethylene. Its width and thickness are determined according to the magnetic field strength of the outer magnetic chamber permanent magnet (45). After calculation, the width is set to 3 mm and the thickness is set to 1.5 mm. The permanent magnet (45) of the outer magnetic chamber is a smaller neodymium iron boron magnet, which is radially magnetized and connected in the middle by the permanent magnet shaft (13). The permanent magnet shaft (13) and the magnetic conductor (43) of the outer magnetic chamber are supported by the permanent magnet bearing (04). The permanent magnet shaft (13) is also connected to the top gear (12) of the outer magnetic chamber. The polarities of the permanent magnets (45) of the outer magnetic chambers (42) of adjacent outer magnetic chambers are arranged in a 90-degree rotation.

[0054] ●Inner magnetic base (31): Made of the same high-strength plastic material as the outer magnetic base (41), with four radially distributed inner magnetic chambers (32) connected to the central rotating shaft (21). The inner magnetic chamber permanent magnet shaft (17) of the inner magnetic chamber (32) is supported by the inner permanent magnet bearing (02) and rigidly connected to the inner magnetic chamber top gear (15). The inner magnetic chamber top gear (15) meshes with the speed change gear (16). The speed change gear shaft (10) of the speed change gear (16) is fixed between the inner magnetic base top gear (18) and the inner magnetic base (31) by a bearing. The central rotating shaft (21) is connected to the housing (01) by a rotating shaft bearing (03) to output power. The housing (01) is made of lightweight aluminum alloy. The inner magnetic base (31) and the outer magnetic base (41) can serve as the rotor and stator of each other.

[0055] ●Magnetic circuit control: The original magnetic circuit control gearbox (11) is replaced with a micro electrical control system, which includes a microchip, a sensor and a drive circuit. The microchip model is STM32F103, the sensor is used to monitor the position and rotation speed of the permanent magnet in real time, and the drive circuit controls the rotation angle of the permanent magnet according to the instructions of the microchip.

[0056] 2. Working principle

It controls the rotation of permanent magnets (35)(45) in real time through a micro electrical control system, changes the orientation of the magnetic field, and makes the magnetic force form a continuous torque to drive the magnetic base (31)(41) to rotate.

[0058] When the outer magnetic chamber (42) rotates 45 degrees relative to the inner magnetic chamber (32), the micro electrical control system receives a signal from the sensor and controls the permanent magnets (35)(45) to rotate 90 degrees, changing from an externally magnetic state to an externally non-magnetic state. The permanent magnets (35)(45) will experience a cycle of S pole magnetic, non-magnetic, N pole magnetic, and non-magnetic when rotating 360 degrees. During operation, the interaction force between the outer magnetic chamber (42) and the inner magnetic chamber (32) is always greater than the force consumed by the magnetic circuit control. After applying an initial external force at startup, continuous operation without external energy input is achieved, providing power for the micro power generation device.

[0059] 3. Beneficial effects

[0064] ●Outer magnetic chamber (42) and inner magnetic chamber (32): Twelve outer magnetic chambers (42) are evenly distributed on the outer magnetic base (41), and ten radial inner magnetic chambers (32) are connected to the central rotation shaft (21) of the inner magnetic base (31). The permanent magnets (35) (45) in the magnetic chamber are high-performance samarium cobalt permanent magnets, and radial magnetization is adopted. The magnetic conductors (33) (43) of the inner and outer magnetic chambers are made of silicon steel. The magnetic conductors of the outer magnetic chamber (42) and the inner magnetic chamber (32) are disconnected from each other and sealed with non-magnetic conductors (34) (44). The non-magnetic conductors are made of brass, and their width and thickness are determined according to the magnetic field strength of the permanent magnet. The width is 6 mm and the thickness is 3 mm.

[0065] • Magnetic circuit control gearbox (11): Reinforced gears are used, made of 20CrMnTi, and carburized and quenched to improve wear resistance and strength.

Each outer magnetic chamber top gear (12) of the outer magnetic chamber (42) meshes with the middle inner magnetic seat top gear (18) fixed on the top of the inner magnetic chamber (32); each inner magnetic chamber top gear (15) of the inner magnetic chamber (32) meshes with the speed change gear (16), which in turn meshes with the gear ring (14) fixed on the outer magnetic seat (41).

[0066] • Switching mechanism: A switching mechanism for quickly switching the rotor and stator states is provided between the inner magnetic base (31) and the outer magnetic base (41). This mechanism consists of an electromagnetic clutch and a control circuit. The electromagnetic clutch is model DLM3-10. The control circuit can control the engagement and disengagement of the electromagnetic clutch according to the instructions of the vehicle driving mode to realize the rapid switching of the inner and outer magnetic base states.

[0067] 2. Working principle

[0068] The device utilizes the principle of like poles repulsion and unlike poles attraction between permanent magnets (45)(35) in the outer magnetic chamber (42) and the inner magnetic chamber (32). Through the transmission of the gearbox (11) controlled by the magnetic circuit, the permanent magnets (35)(45) are driven to rotate in real time, changing the orientation of the magnetic field and making the magnetic force form a continuous torque, driving the magnetic base (31)(41) to rotate, thus providing driving force for new energy vehicles.

[0069] When it is necessary to switch the vehicle driving mode, the control circuit issues a command, the electromagnetic clutch actuates, and the rotor and stator states of the inner magnetic base (31) and outer magnetic base (41) are quickly switched. During operation, the heat dissipation device works continuously to dissipate the heat generated by the device in a timely manner, ensuring that the device operates at a suitable temperature.

[0072] Example 3: Device with Dual Magnetic Circuit Control

[0073] 1. Structural Composition

[0074] Based on the original device structure, an independent magnetic circuit control system is added. The two magnetic circuit control systems are the first magnetic circuit control system and the second magnetic circuit control system.

[0075] • First magnetic circuit control system: including first magnetic circuit control gearbox and related sensors and control circuits. The structure of the first magnetic circuit control gearbox is the same as the original magnetic circuit control gearbox (11), and it is used to control the permanent magnets (35)(45) in the inner and outer magnetic chambers 1-6.

[0076] ● Second magnetic circuit control system: includes second magnetic circuit control gearbox and related sensors and control circuits. Its structure is the same as that of the first magnetic circuit control system. It is used to control the permanent magnets (35)(45) in the inner and outer magnetic chambers of No. 7-12.

[0077] • Switching device: A switching device is provided, which consists of a controller and a relay. The controller model is PLCS7-200. It can monitor the operating status of the two magnetic circuit control systems in real time. When one system fails, the controller issues a command, the relay activates, and the other system immediately takes over the control.

[0078] Other structures, such as the outer magnetic base (41), inner magnetic base (31), inner magnetic chamber (32), and outer magnetic chamber (42), are the same as the original device.

[0079] 2. Working principle

[0080] When the device is running normally, the two sets of magnetic circuit control systems work simultaneously, controlling the permanent magnets (35) and (45) of different groups of inner and outer magnetic chambers respectively. Through gear transmission, the permanent magnets are driven to rotate, changing the magnetic field orientation, so that the magnetic force forms a continuous torque and drives the magnetic base to rotate.

[0081] The switching device monitors the operating status of the two systems in real time. When the first magnetic circuit control system fails, the controller detects the fault signal and immediately controls the relay to cut off the control of the first magnetic circuit control system. At the same time, the second magnetic circuit control system takes over the control of all the permanent magnets (35) and (45) in the inner and outer magnetic chambers. Similarly, when the second magnetic circuit control system fails, the first magnetic circuit control system takes over the control to ensure the continuous operation of the device.

[0082] 3. Beneficial effects

[0083] This device with dual magnetic circuit control uses two independent magnetic circuit control systems to control different groups of permanent magnets, which improves the reliability and safety of the device. When one system fails, the other system can immediately take over, avoiding interruption of device operation and ensuring the continuity of power output.

[0084] Example 4: Device using a novel magnetically conductive material

[0085] 1. Structural Composition

[0086] ●Inner and outer magnetic chamber conductors (33)(43): A new type of nanocrystalline alloy magnetic material is used, which has a magnetic permeability that is more than 30% higher than that of traditional silicon steel. The conductors are divided into two halves and surround the outside of the permanent magnet (35)(45). The dimensions of the inner and outer magnetic chamber conductors (33)(43) are determined according to the size of the permanent magnet and the overall structure of the device.

[0087] • Non-magnetic materials in the inner and outer magnetic chambers (34)(44): Made of lightweight carbon fiber composite material with a density of 1.6 g / cm³ 3 Compared to traditional non-magnetic materials, the weight is reduced by 40%. The non-magnetic body is connected at the break of the magnetic body, and its width and thickness are matched according to the magnetic field strength of the permanent magnet (35)(45), with a width of 6 mm and a thickness of 3 mm.

[0088] Other structures such as the outer magnetic base (41), inner magnetic base (31), magnetic circuit control gearbox (11), permanent magnet (35) (45) are the same as the original device, among which the permanent magnet adopts neodymium iron boron magnet.

[0089] 2. Working principle

[0090] The device utilizes the principle of like poles repulsion and unlike poles attraction between permanent magnets (45)(35) in the outer magnetic chamber (42) and the inner magnetic chamber (32). Through the transmission of the gearbox (11) controlled by the magnetic circuit, the permanent magnets (35)(45) are driven to rotate in real time, changing the magnetic field orientation and making the magnetic force form a continuous torque, driving the magnetic base (31)(41) to rotate.

[0091] Because the inner and outer magnetic chambers' magnetic conductors (33) and (43) are made of a new type of nanocrystalline alloy magnetic material with high permeability, they can effectively concentrate magnetic lines of force, reduce magnetic leakage loss, and make the process of converting magnetic energy into mechanical energy more complete; the non-magnetic conductors are made of carbon fiber composite material, which reduces the overall weight of the device and reduces energy consumption during operation. After the initial external force is applied at startup, the interaction force between the outer magnetic chamber (42) and the inner magnetic chamber (32) is always greater than the force consumed by the magnetic circuit control, thus achieving continuous and stable operation.

[0092] 3. Beneficial effects

[0093] This device, which uses a novel magnetic material, reduces magnetic leakage loss and improves energy conversion efficiency because the magnetic conductor is made of nanocrystalline alloy material; the non-magnetic conductor is made of carbon fiber composite material, which reduces the weight of the device and reduces energy consumption, making the device more energy-efficient and environmentally friendly.
