Description

Technical Field

[0001] This invention relates to the field of generator and energy recovery technology, specifically to a planetary permanent magnet axial gate-type magnetic reluctance reversing generator and its power generation method. Background Technology

[0002] Traditional AC generators and permanent magnet synchronous generators rely entirely on Lenz's law for their operation: while the windings cut the magnetic field to generate induced electrical energy, they inevitably produce a reverse electromagnetic braking torque that opposes the rotor's rotation. The prime mover must continuously output additional power to overcome this electromagnetic resistance, and this power is entirely dissipated in the form of copper losses, iron losses, and heat energy. This is an inherent core defect that limits the overall conversion efficiency of the generator.

[0003] Currently, existing improvement solutions in the industry mainly aim to slightly reduce losses by optimizing core materials, reducing air gaps, and optimizing winding arrangements. However, these solutions do not fundamentally change the underlying opposing magnetic field structure, which inherently generates resistance during power generation, resulting in limited efficiency improvements. Furthermore, traditional generator stator / rotor cores often employ independent pole shoe stamping and segmented assembly processes, leading to a large number of parts, complex processing steps, difficulty in achieving consistent assembly precision, and high manufacturing costs. In conventional motors, the magnetic circuit is arranged circumferentially, resulting in long magnetic field transmission paths, high magnetic reluctance, and severe edge magnetic leakage, further reducing power generation output efficiency.

[0004] Conventional planetary permanent magnet generators mostly adopt a radial magnetic field structure with permanent magnets arranged radially. This makes it impossible to form a continuous and smooth tangential alternating magnetic field, resulting in large torque pulsation and high output voltage harmonics. Furthermore, the planetary transmission and excitation magnetic field are independent of each other, making it impossible to achieve forced synchronization between the mechanical phase and the magnetic field phase. This leads to speed slippage during operation and poor stability of the output power. Summary of the Invention

[0005] The purpose of this invention is to provide a planetary permanent magnet axial gate-type magnetic reluctance reversing generator and its power generation method. Through multiple synergistic innovative structures, including Tai Chi S-shaped magnetic field topology reconstruction of the air gap magnetic field vector distribution, an integrated silicon steel rolled gate-type magnetic core shortening the magnetic circuit, planetary gear mechanical locking to fix the transmission ratio, S-shaped meshing convex edge forcibly synchronizing the mechanical and magnetic field phases, and a double-layer staggered-phase iron core for mechanically smoothing the torque waveform, this invention addresses the three core pain points of traditional generators from the ground up. These problems include the inability to eliminate electromagnetic resistance torque during power generation, high inherent losses; cumbersome and costly iron core processing and assembly; and long magnetic circuits, large magnetic leakage, significant torque pulsation, and poor output waveform.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A planetary permanent magnet axial gate-type reluctance reversing generator includes a generator base at the rear end, a planetary carrier and a frame end cover sealed and fixed to the front end of the planetary carrier fixedly mounted in front of the generator base, an outer rotor housing enclosing the planetary carrier and a housing end cover sealed and fixed to the front end of the outer rotor housing and enclosing the frame end cover rotatably mounted in front of the planetary carrier, and a conductive slip ring coaxially fixed to the front end of the housing end cover; a power input shaft extending through to the front of the planetary carrier is rotatably mounted inside the generator base, and a sun gear located in front of the planetary carrier is coaxially mounted on the shaft of the power input shaft; four planetary rotor shafts evenly distributed circumferentially around the power input shaft are rotatably mounted inside the planetary carrier, and planet gears meshing with the sun gear are coaxially mounted on the shaft of each planetary rotor shaft; an inner ring gear meshing with each planet gear is fixed inside the outer rotor housing; and a coil outer rotor located in front of the gear ring is also fixed inside the outer rotor housing, with twenty-four generators on the coil outer rotor. The electric coil has an outer rotor and a generating coil that serve as the power output end and the generating body, respectively. The core of the outer rotor is made of silicon steel sheet with an inner reverse edge rolling process, and the cross-section of the core has a gate-shaped frame structure, which constitutes an axial gate-shaped magnetic circuit. On the shaft of each planetary rotor, an axially magnetized central disk permanent magnet is also coaxially fixed. On the front and rear end faces of the central disk permanent magnet, a Taiji permanent magnet rotor is also coaxially fixed. Its magnetic pole distribution is in the Taiji Yin-Yang fish dividing line format, which is used to generate a spatially continuously changing tangential magnetic field in the air gap of the outer rotor.

[0007] By adopting the above-mentioned scheme, the segmented shell combined with sealed end caps forms a fully enclosed protective structure, providing dustproof, waterproof, and oil-proof capabilities, making it suitable for harsh working conditions such as outdoor wind power, vehicle-mounted applications, and construction machinery. The front-end coaxial conductive slip ring enables 360° unrestricted continuous rotational power transmission, solving the problem of twisted and tangled output cables in traditional rotary generators. The planetary transmission layout of sun gear + four sets of planetary gears + internal gear ring results in a highly compact structure, small overall radial dimensions, lightweight equipment, and high space utilization. The central disc permanent magnet, Taiji permanent magnet rotor, and planetary rotor shafts are coaxially integrated, and the excitation structure and planetary transmission are integrated into a single design, eliminating the need for an additional independent excitation drive mechanism, simplifying the internal layout of the machine, and reducing transmission components. The portal frame iron core constructs an independent axial guiding magnetic circuit, which differs from the traditional circumferential long magnetic circuit of motors, providing a structural basis for shortening the magnetic circuit, reducing magnetic resistance, and suppressing magnetic leakage. The Taiji Yin-Yang fish S-shaped segmented magnetic poles can generate a continuous, smooth, and abrupt tangential rotating magnetic field, fundamentally avoiding the torque pulsation and high harmonic defects caused by the abrupt change in the magnetic field of traditional radial permanent magnets.

[0008] As a preferred embodiment of a planetary permanent magnet axial portal reluctance reversing generator, the core of the outer rotor of this coil is manufactured by layering and insulating multiple strips of silicon steel sheets of varying widths onto a drum. The silicon steel sheets have pre-set grooves that are aligned and stacked layer by layer to form an axially penetrating inner groove. After winding, the end face of the core is cut to open the groove, forming a portal frame-type pole shoe. An insulating layer is placed between the silicon steel sheets to effectively suppress interlayer eddy currents, reduce core eddy current losses, and improve energy conversion efficiency. The integrated pole shoe, formed by groove alignment winding and end face cutting, eliminates the traditional multiple processes of stamping, grinding, embedding, and locking of separate pole shoes, significantly reducing the number of parts, simplifying the production line, and significantly reducing material and labor manufacturing costs.

[0009] As a preferred embodiment of a planetary permanent magnet axial gate-type reluctance reversing generator, the outer rotor core of the coil consists of two layers of axially connected silicon steel rolled cores. The pole shoes corresponding to the two core layers are offset by half a Tai Chi magnetic field angle along the circumferential direction, and the torque waveform is smoothed through mechanical superposition. The two core layers work independently, each generating a periodic pulsating torque waveform; after being assembled with the two sets of waveforms offset by half a Tai Chi angle, they are superimposed to smooth out peaks and fill valleys, significantly reducing the torque pulsation coefficient, and significantly reducing vibration and noise during power generation.

[0010] As a preferred embodiment of a planetary permanent magnet axial gate-type reluctance reversing generator, the central disk permanent magnet is divided into two groups and paired in pairs. The magnetic pole polarities of the taiji permanent magnet rotors assembled in each pair of central disk permanent magnets are opposite. The central disk permanent magnets on the circumference of the whole machine are arranged in an alternating N / S and SN pattern. The magnetic poles on one side of a single taiji permanent magnet rotor are always all N poles or all S poles. The periodic reversal of the induced polarity of the coil winding is naturally achieved by the revolution of the planetary gears. The N / S alternating and uniform arrangement allows adjacent taiji permanent magnet rotors to directly form independent closed magnetic units. The magnetic lines of force complete the N and S pole closure nearby, greatly reducing long-distance diffusion and leakage of magnetic field. Each taiji permanent magnet rotor has only a single magnetic pole on one side, and there are no N and S mixed magnetic fields inside the rotor to cancel each other out, maximizing the utilization rate of the permanent magnet magnetic field.

[0011] As a preferred embodiment of a planetary permanent magnet axial gate-type reluctance reversing generator, the outer rotor of the coil has 24 cavities evenly distributed around its circumference. Each cavity is divided into three independent pole shoes, which are sequentially defined as the first pole shoe, the second pole shoe, and the third pole shoe along the circumference. The first pole shoe windings of all cavities are electrically connected to form the A-phase winding, the second pole shoe windings form the B-phase winding, and the third pole shoe windings form the C-phase winding. The three-phase windings are connected in a star configuration and a neutral line is led out, together forming a three-phase four-wire power output. The 24 Tai Chi cavities are evenly distributed along the circumference, and the A, B, and C three-phase windings are spatially symmetrically distributed. The three-phase impedance and induced electromotive force are highly balanced, and the three-phase voltage and current imbalance is extremely low, resulting in excellent power supply quality. The one-pole three-shoe distributed winding has an equal number of conductors in each phase, which can be directly matched with high-power three-phase loads such as industrial standard three-phase asynchronous motors and energy storage inverters. The star connection leads out the neutral line, which can simultaneously output 380V line voltage and 220V phase voltage, accommodating both high-power power equipment and small control components, thus broadening the applicable scenarios of the equipment.

[0012] As a preferred embodiment of a planetary permanent magnet taiji axial gate-type reluctance reversing generator, each of the anode and cathode poles of the taiji permanent magnet rotor is equipped with a fisheye magnet structure. The anode and cathode poles are separated by a smooth S-shaped anode-cathode pole division curve. The two sets of fisheye structures a and b on the S-shaped anode-cathode pole division curve are located exactly on the tangent line at the midpoint c between a and b, thus pre-setting the direction of the tangential component of the Ampere force. The smooth S-shaped curve divides the anode and cathode poles without any abrupt magnetic field boundary points, allowing the magnetic field vector within the air gap to rotate continuously without instantaneous impact torque, resulting in less vibration during operation. By precisely locking the direction of the tangential resultant force of the Ampere force through the spatial position of the fisheye magnets, the electromagnetic resultant force after the winding is current-carrying is aligned with the rotor rotation outside the coil, realizing the core reluctance reversing function of this invention and converting the traditional reverse resistance torque into a forward driving thrust.

[0013] As a preferred implementation of a planetary permanent magnet axial portal reluctance reversing generator, the above planetary transmission geometry satisfies: number of teeth on the ring gear = number of teeth on the sun gear + 2 × number of teeth on the planet gears; where: the module is 2.5, the number of teeth on the sun gear is 56, the number of teeth on the planet gears is 28, and the number of teeth on the internal ring gear is 112; it also satisfies that: under the condition that the planetary carrier is stationary, the speed ratio between the sun gear and the rotor outside the coil is mechanically locked at -0.5, and the whole machine operates synchronously without speed difference. By strictly matching the gear parameters to the standard geometric constraints of the planetary transmission, the gear meshing is smooth, without tooth jamming or skipping faults, the transmission noise is low, the gear wear is small, and the gear service life is extended; relying on the gear mechanical structure to forcibly lock the fixed transmission ratio, the magnetic field alternation frequency corresponds one-to-one with the rotor speed, eliminating the electromagnetic slip of traditional permanent magnet generators, the output voltage and frequency are not affected by load fluctuations, and the power supply stability is greatly improved; the -0.5 fixed speed ratio accurately matches the alternation cycle of the taiji magnetic field, optimizes the magnetic field cutting speed range, and maximizes energy conversion efficiency.

[0014] As a preferred embodiment of a planetary permanent magnet tai-pole axial portal reluctance reversing generator, the tai-pole permanent magnet rotor end face is integrally formed with a rigid tai-pole meshing convex edge. The height of the convex edge is equal to 1 / 2 of the air gap, and the contour of the convex edge replicates the Tai-pole S-shaped segmented curve, forcibly synchronizing the magnetic field phase with the mechanical rotation phase. The convex edge height is half the air gap, which prevents mechanical scraping and collision with the portal iron core pole shoes, and can accurately limit the relative position of the permanent magnet rotor and the iron core pole shoes. The S-shaped contour meshing convex edge synchronously constrains the alternating phase of the mechanical rotation phase and the air gap magnetic field, which can reduce torque loss and voltage waveform distortion caused by phase offset.

[0015] As a preferred embodiment of a planetary permanent magnet axial portal reluctance reversing generator, the magnetic lines of force generated by the central disk permanent magnet are guided to the working air gaps on both sides via the portal frame core, forming the shortest axial closed magnetic circuit between the two sets of opposing portal frame cores, reducing overall magnetic reluctance and leakage magnetic loss. The magnetic lines of force enter and exit directly between the opposing portal frames, eliminating the traditional long circumferential path of the motor, significantly shortening the total length of the magnetic circuit, and significantly reducing the overall magnetic reluctance; the axially opposed closed loop has a strong ability to constrain the magnetic field, greatly suppressing the diffusion of magnetic leakage at the ends and edges of the core, and allowing the vast majority of magnetic lines of force to pass through the windings and effectively do work, significantly improving the magnetic field utilization rate.

[0016] A power generation method using the aforementioned planetary permanent magnet axial gate-type reluctance reversing generator, with the outer rotor of the coil as the active power input terminal of the whole machine, when an external load is connected and the generator enters the power generation mode, the electromagnetic reverse torque generated by the power generation is converted into a forward thrust that drives the outer rotor of the coil to rotate by the magnetic field topology orientation. The prime mover's drive input power does not increase, only compensating for mechanical friction losses. It includes the following steps: S1. External power drives the sun gear to rotate, and the meshing of the sun gear drives the four sets of planetary gears to revolve around the center. S2. The central disk permanent magnet provides axial basic excitation, and the planetary gear end face Taiji permanent magnet rotor periodically and alternately sweeps the air gap of the outer rotor coil as it revolves. S3, the Taiji S-shaped magnetic pole generates a smooth rotating vector magnetic field in the air gap. The magnetic field cuts the three-phase winding to generate an induced electromotive force and output electrical energy. S4. Position the two sets of fisheye structures a and b on the S-shaped polarity dividing curve exactly on the tangent line where the midpoint c between a and b is located. This completes the pre-setting of the direction of the tangential component of the Ampere force, thereby converting the electromagnetic resistance torque generated by Lenz's law into a driving thrust in the same direction as the rotor outside the coil. S5: The two-layer staggered phase gate-type iron core mechanically superimposes the two sets of torque waveforms to eliminate torque pulsation and continuously and stably output three-phase AC power.

[0017] By adopting the above scheme, the core innovation of reluctance conversion is achieved at the level of the whole machine operation logic, breaking the inherent law of traditional generators that "the greater the load, the greater the resistance of the prime mover, and the higher the energy consumption". When the load power increases, the input power of the prime mover does not increase, which greatly saves the energy consumption of the front-end drive. The operation process combines the advantages of all structures such as planetary transmission, permanent magnet excitation, portal iron core, and double-layer phase separation, resulting in stable torque and standard output waveform throughout the process, and can generate electricity continuously and stably for a long time. High-efficiency power generation is achieved by relying on the pure mechanical + permanent magnet topology structure. The whole machine hardware structure is simple, the operation reliability is high, and the maintenance cost is low.

[0018] The beneficial effects of this invention are: 1. Innovative underlying electromagnetic mechanism, breaking through the efficiency ceiling of traditional generators: By combining a Tai Chi S-shaped topology permanent magnet rotor with a fisheye magnet spatial layout, the vector distribution of the air gap magnetic field is reconstructed, and the direction of the tangential component of the Ampere force in the current-carrying winding is precisely changed. The reverse electromagnetic resistance torque generated by Lenz's law is transformed into the forward thrust that drives the rotor outside the coil to rotate. When the load power increases, the input power of the prime mover does not increase, only compensating for a small amount of mechanical friction loss. The inherent additional energy consumption of traditional generators is eliminated from the electromagnetic mechanism, and the energy conversion efficiency is improved by leaps and bounds. 2. Integrated rolled gate-shaped iron core simplifies manufacturing process, reduces costs, and optimizes magnetic circuit performance: The outer rotor iron core of the coil is made of wide and narrow silicon steel sheets, which are insulated and rolled layer by layer and cut at the end face to form an integrated gate-shaped pole shoe. This eliminates the traditional process of stamping, embedding, and locking separate pole shoes, significantly reducing the number of parts, simplifying the processing and assembly process, and significantly reducing the cost of mass production. The axially opposed gate-shaped frame forms the shortest closed magnetic circuit, with no extra detours in the magnetic lines of force, which greatly reduces the magnetic reluctance of the whole machine. The leakage magnetic field at the edge and end of the iron core is effectively suppressed, and the magnetic field utilization rate is significantly improved. 3. The double-layer staggered iron core mechanical smooth torque waveform provides excellent power output quality: The two axially connected iron cores are staggered by half a Taiji magnetic field angle along the circumference. The superposition of two sets of periodic pulsating torque waveforms achieves peak shaving and valley filling, resulting in an extremely low torque pulsation coefficient and a significant reduction in vibration and noise during operation. 4. Planetary gear mechanical locking + S-shaped meshing convex edge dual phase synchronization, no slippage, stable power supply: The gear parameters strictly match the geometric constraints of the planetary transmission, mechanically forcibly locking the sun gear and the outer rotor of the coil at a fixed speed ratio of 0.5, structurally reducing electromagnetic slippage; the S-shaped meshing convex edge on the end face of the Taiji rotor synchronously constrains the mechanical rotation phase and the alternating phase of the magnetic field, and the magnetic field change is perfectly matched with the rotor rotation, so that the output voltage amplitude and frequency are not affected by load fluctuations; 5. The alternating NS permanent magnet layout provides strong magnetic field closure and long service life of the permanent magnets: Four sets of Tai Chi permanent magnet rotors are arranged in alternating NSNS patterns around the circumference. Adjacent rotors directly form independent magnetic closed units, and the magnetic lines of force complete the NS loop conduction nearby, further reducing long-distance diffusion and leakage magnetic field; each rotor has a single magnetic pole on one side, and there is no mutual cancellation of magnetic field loss within the rotor. Under the same specifications of permanent magnets, the excitation magnetic field strength is higher, the magnetic load of the permanent magnets during long-term operation is smaller, and the service life of the whole machine is extended. 6. 24-cavity, one-pole, three-shoe, three-phase, four-wire winding, adaptable to various electrical equipment in all scenarios: The 24 cavities are symmetrically distributed with three-phase windings along the circumference, resulting in highly balanced three-phase impedance and induced electromotive force, and low three-phase imbalance; the star connection leads out the neutral line, which can simultaneously output 380V industrial line voltage and 220V single-phase voltage, suitable for various working conditions such as wind power generation, vehicle energy recovery, aviation, and construction machinery.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 12 As shown, a planetary permanent magnet axial portal reluctance reversing generator is provided. The whole machine is divided into four major components: sealed housing assembly, planetary gear transmission assembly, permanent magnet excitation rotor assembly, and portal reluctance coil outer rotor assembly.

[0024] like Figures 1 to 3As shown, the sealed housing assembly includes: a cast iron generator base 1 at the rear of the equipment, with a bearing support machined inside the generator base 1 to support the power input shaft 7; a planetary carrier 2 is fixed to the front of the generator base 1 with bolts, and a rubber sealing gasket is fitted to the front of the planetary carrier 2 to lock the end cover 3 of the carrier body, thus sealing and preventing dust from the internal gear cavity of the planetary carrier 2; an outer rotor housing 4 that can rotate freely around the central axis is fitted on the outside of the planetary carrier 2, and a housing end cover 5 is sealed and assembled at the front of the outer rotor housing 4, with a conductive slip ring 6 coaxially assembled in the central through hole of the housing end cover 5; the stationary end of the conductive slip ring 6 is connected to the external output cable, and the rotating end is connected to the internal three-phase winding through the lead wire, realizing 360° infinite continuous rotation power transmission, and the entire housing forms a fully sealed protective structure.

[0025] like Figures 4 to 6 As shown, the planetary gear transmission assembly consists of: a power input shaft 7 extending forward from the generator base 1 bearing to the front of the planetary carrier 2; an interference fit between the shaft and the sun gear 8; a gear module of 2.5 and 56 teeth; four planetary rotor shafts 9 are evenly arranged along the circumference of the planetary carrier 2 at 90°; each planetary rotor shaft 9 is equipped with support bearings at both ends to achieve rotation; a planetary gear 10 is fixed in the middle of the planetary rotor shaft 9, with 28 teeth; the four planetary gears 10 simultaneously mesh with the central sun gear 8 and the internal gear ring 11 on the inner wall of the outer rotor housing 4; the internal gear ring 11 has 112 teeth, strictly satisfying the planetary transmission geometric relationship of the number of teeth of the gear ring 11 = the number of teeth of the sun gear 8 + 2 × the number of teeth of the planetary gear 10; during operation, the planetary carrier 2 is completely fixed, and the speed ratio between the sun gear 8 and the outer rotor 12 of the coil is mechanically locked at -0.5, with opposite directions of rotation, and synchronous operation without speed slippage throughout the entire process.

[0026] like Figures 7 to 10 As shown, the permanent magnet excitation rotor assembly consists of: a centrally magnetized permanent magnet 14 coaxially fixed in the middle of each planetary rotor shaft 9; and a Tai Chi permanent magnet rotor 15 bolted to the front and rear ends of the permanent magnet. The permanent magnet rotors on the four planetary rotor shafts 9 are paired in pairs, with opposite polarities of the anode and cathode magnetic poles. The entire circumference is evenly arranged in alternating NS and SN configurations. Figure 9 As shown; the single-piece Taiji permanent magnet rotor 15 has one side entirely composed of pure N poles and the other side entirely composed of pure S poles. The anode and cathode poles are separated by a smooth S-shaped anode-cathode pole division curve. The two sets of fisheye structures a and b on the S-shaped anode-cathode pole division curve are precisely located on the tangent line at the midpoint c between a and b, thus pre-setting the direction of the tangential component of the Ampere force. Figure 10 As shown; the Taiji permanent magnet rotor 15 has an integrally formed S-shaped rigid meshing convex edge on its end face. The height of the convex edge is equal to 1 / 2 of the air gap of the outer rotor 12. During rotation, it is matched with the pole shoe of the portal iron core for limiting and forcing the mechanical phase and magnetic field to alternate phase.

[0027] like Figures 3 to 6 , Figures 11 to 12As shown, the portal-shaped magnetic coil outer rotor 12 assembly consists of: the outer rotor housing 4 and the inner gear ring 11, where the outer rotor 12 is fixed; the iron core is formed by winding multiple insulating silicon steel sheets of different widths layer by layer; the silicon steel sheets are pre-stamped with axial grooves, which are aligned vertically during winding to form a through groove; the two ends of the iron core are cut with grooves; a portal-shaped frame pole shoe is integrally formed; the upper crossbeam of the portal frame forms a magnetic yoke; the two pole shoes on both sides face the Taiji permanent magnet rotor 15 to form a working air gap; the iron core of the outer rotor 12 is assembled axially in series from two identical rolled iron cores; the pole shoes of the two cores are staggered by half a Taiji magnetic field angle along the circumference; 24 Taiji cavities 16 are evenly opened around the circumference of the outer rotor 12; each Taiji cavity 16 has three independent pole shoes (first, second, and third sets) inside, as shown in the figure. Figure 11 As shown; all the first pole shoe coils of the three-phase winding are connected in series as phase A, the second pole shoe coils are connected in series as phase B, and the third pole shoe coils are connected in series as phase C; the ends of the three-phase windings are connected in a star configuration, and a neutral line is led out from the common midpoint. The three-phase four-wire terminals are connected to the front conductive slip ring 6 through the lead wire to output electrical energy; the magnetic lines of force of the central disk permanent magnet 14 pass through one side portal pole shoe, the working air gap, and the opposite portal pole shoe, and form the shortest axial closed magnetic circuit through the portal beam yoke.

[0028] like Figures 1 to 12 As shown, the power generation principle of this planetary permanent magnet taiji axial gate-type magnetic reluctance reversing generator is as follows: An external prime mover connects to the power input shaft 7, driving the sun gear 8 to rotate continuously. The sun gear 8 meshes and drives four planetary rotor shafts 9 to revolve around the center of the entire machine. The central disk permanent magnet 14 provides a unified axial excitation magnetic field, and the planetary rotor shafts 9 drive the taiji permanent magnet rotor 15 to revolve synchronously. The S-shaped segmented magnetic poles generate a continuous and smooth rotating vector magnetic field in the working air gap of the rotor 12 outside the coil. The alternating magnetic field continuously cuts the three-phase distributed windings A, B, and C, generating an induced electromotive force inside the windings. The electrical energy is stably output to the external load through the front conductive slip ring 6. Relying on the taiji rotor S... The spatial layout of the curved shape ensures that the tangential component of the resultant Ampere force generated by the winding current is aligned with the rotation direction of the rotor 12 outside the coil, transforming the traditional reverse electromagnetic resistance torque into forward driving thrust. The double-layer staggered phase gate core superimposes two sets of periodic pulsating torque waveforms, eliminating torque pulsation by smoothing peaks and filling valleys, and continuously outputting standard three-phase AC power with stable waveform and low harmonic content. When the external load power increases and the winding operating current rises, the forward driving thrust synchronously lifts the auxiliary rotor to rotate. The prime mover only needs to compensate for the minor mechanical friction losses generated by gear meshing, bearings, and slip rings, and the input power will not increase with the load.

[0029] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Each Tai Chi cavity is divided into 3 sets of independent pole shoes, which are defined as the first pole shoe, the second pole shoe, and the third pole shoe in sequence along the circumference. The first pole shoe windings of all Tai Chi cavities are electrically connected to form the A-phase winding, all the second pole shoe windings form the B-phase winding, and all the third pole shoe windings form the C-phase winding. The three-phase windings adopt a star connection and lead out a neutral line to form a three-phase four-wire power output.

The two sets of fisheye structures a and b on the S-shaped anode and cathode magnetic pole dividing curve are located on the tangent line at the midpoint c between a and b, thus completing the pre-setting of the direction of the tangential component of the Ampere force.

7. A planetary permanent magnet axial portal reluctance reversing generator according to claim 1, characterized in that, The above planetary transmission geometric relationship satisfies: number of teeth on the ring gear = number of teeth on the sun gear + 2 × number of teeth on the planet gears; where: the module is 2.5, the number of teeth on the sun gear is 56, the number of teeth on the planet gears is 28, and the number of teeth on the internal ring gear is 112; it also satisfies that: when the planet carrier is stationary, the speed ratio between the sun gear and the outer rotor of the coil is mechanically locked at -0.5, and the whole machine operates synchronously without speed difference.

A planetary permanent magnet axial portal reluctance reversing generator according to claim 1, characterized in that, The end face of the Taiji permanent magnet rotor is integrally formed with a rigid Taiji meshing convex edge. The height of the convex edge is equal to 1 / 2 of the air gap. The contour of the convex edge replicates the Taiji S-shaped segmented curve, forcing the synchronous magnetic field phase and mechanical rotation phase.

9. A planetary permanent magnet axial portal reluctance reversing generator according to claim 1, characterized in that, The magnetic lines of force generated by the central disk permanent magnet are guided to the working air gaps on both sides via the portal frame iron core, forming the shortest axial closed magnetic circuit between the two sets of relatively arranged portal frame iron cores, thereby reducing the overall magnetic resistance and reducing leakage magnetic loss.

10. A method for generating electricity using a planetary permanent magnet axial gate-type reluctance reversing generator according to any one of claims 1-9, characterized in that, It includes the following steps: S1. External power drives the sun gear to rotate, and the meshing of the sun gear drives the four sets of planetary gears to revolve around the center. S2. The central disk permanent magnet provides axial basic excitation, and the planetary gear end face Taiji permanent magnet rotor periodically and alternately sweeps the air gap of the outer rotor coil as it revolves. S3, the Taiji S-shaped magnetic pole generates a smooth rotating vector magnetic field in the air gap. The magnetic field cuts the three-phase winding to generate an induced electromotive force and output electrical energy. S4. Position the two sets of fisheye structures A and B on the S-shaped polarity dividing curve exactly on the tangent line between the midpoints of A and B, thus presetting the direction of the tangential component of the Ampere force, thereby converting the electromagnetic resistance torque generated by Lenz's law into a driving thrust in the same direction as the rotor outside the coil. S5: The two-layer staggered phase gate-type iron core mechanically superimposes the two sets of torque waveforms to eliminate torque pulsation and continuously and stably output three-phase AC power.
