Description

Technical Field

[0001] This invention relates to the field of generator technology, and in particular to a generator with a rotor made of non-magnetic material. Background Technology

[0002] A typical generator consists of a stator, rotor, end covers, and bearings. The stator comprises a stator core, coil windings (magnets), a frame, and other structural components that hold these parts in place. The rotor consists of a rotor core (or magnetic poles, yoke), windings (excitation coils), retaining rings, center rings, slip rings, a fan, and a shaft. The stator and rotor are connected and assembled by bearings and end covers. External force drives the transmission wheel, causing the rotor to rotate within the stator, cutting magnetic lines of force and generating an induced electromotive force (EMF). This EMF is then led out through terminals and connected to a circuit, thus producing an electric current.

[0003] As mentioned above, a traditional generator consists of a rotor and a stator. The rotor can be a magnetic field generating device or a coil that cuts magnetic field lines. Due to its mass, the rotor suffers losses in addition to overcoming air resistance. The electromagnetic resistance generated by the generator load will increase the losses when the generator is under load. The rotor's own huge mass makes it difficult for the rotor to rotate and its bearings suffer significant wear. This results in a large energy loss and relatively low efficiency of traditional generators. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a non-magnetic rotor reluctance generator, in which the rotor is not affected by the magnetic force of the inner stator magnet, requires very little input power, and has smooth start-up and operation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A non-magnetic rotor generator includes a housing, a magnet assembly, a coil assembly, a transmission assembly, and a rotor assembly. The housing includes a detachably connected front outer shell and a rear outer shell. The magnet assembly and the coil assembly are installed inside the housing. The magnet assembly includes a magnetic core and a magnetic pole group arranged on the magnetic core. The coil assembly includes a silicon steel sheet and a coil group arranged on the silicon steel sheet. The magnetic pole group of the magnet assembly and the coil group of the coil assembly are arranged in a mutually cooperating manner. The transmission assembly includes a transmission wheel, a transmission shaft, and a bearing. The transmission shaft is rotatably installed inside the housing through the bearing, and the axial front end of the transmission shaft extends out of the front outer shell and is fitted with a transmission wheel. The rotor assembly includes a support and an isolation section. A drive shaft is inserted and fixedly installed at the center of the support. The isolation section is fixedly arranged on the outer periphery of the support. The isolation section includes several non-magnetic isolators, which are evenly distributed around the drive shaft. A magnetic leakage port is provided between two adjacent non-magnetic isolators. A gap space is provided between the magnet assembly and the coil assembly. The isolation section is arranged in the gap space. The width of one non-magnetic isolator is sufficient to cover at least one magnetic pole group to isolate its magnetic field. Under the action of external force, the drive wheel can drive several non-magnetic isolators to rotate in the gap space through the drive shaft.

[0007] By adopting the above technical solution, the present invention has the following beneficial effects:

[0008] 1. The present invention fixes the magnet assembly and the coil assembly inside the housing, and provides a gap space between the magnet assembly and the coil assembly. Several non-magnetic isolators are arranged in the gap space. During the rotation, the several non-magnetic isolators successively isolate the magnetic field received by the coil, thereby changing the magnetic field received by the coil and generating current.

[0009] 2. When external power is input, the non-magnetic material rotor is not affected by the magnetic force of the inner stator magnet, nor by the magnetic resistance generated by the generator load. Therefore, the required input power is very small, and the starting and running speeds are very smooth, so as to achieve the effect of energy saving and emission reduction.

[0041] The specific implementation of the invention will be further described below with reference to the accompanying drawings.

[0042] Example 1

[0043] like Figure 1 As shown, the side where the transmission wheel 104 is located is defined as the front side (front end) of the generator, and the opposite side is defined as the rear side (rear end) of the generator. The orientation of the transmission shaft is explained later with axial, radial and circumferential directions as auxiliary.

[0044] like Figures 1-15As shown in Embodiment 1, a non-magnetic material rotor reluctance generator includes a housing, a magnet assembly, a coil assembly 106, a transmission assembly, and a rotor assembly. The housing includes a detachably connected front outer shell 101 and a rear outer shell 102. The magnet assembly and the coil assembly 106 are installed inside the housing. The magnet assembly includes a magnetic core 108 and a magnetic pole group 107 arranged on the magnetic core. The coil assembly 106 includes a silicon steel sheet and a coil group arranged on the silicon steel sheet. The magnetic pole group 107 of the magnet assembly and the coil group of the coil assembly are arranged in a mutually cooperating manner. The transmission assembly includes a transmission wheel 104, a transmission shaft 105, and bearings (including a front bearing 111 and a rear bearing 112). The transmission shaft 105 is rotatably installed inside the housing through the bearings, and the axial front end of the transmission shaft 105 passes through... The front housing (axial end) is fitted with a drive wheel 104; the rotor assembly includes a support 110 and an isolation section 109. A drive shaft 105 is inserted and fixedly installed at the center of the support 110. The isolation section 109 is fixedly disposed on the outer periphery of the support 110. The isolation section includes several non-magnetic isolators, which are evenly distributed around the drive shaft 105. A magnetic leakage port is provided between two adjacent non-magnetic isolators. A gap space is provided between the magnet assembly and the coil assembly 106. The isolation section 109 is arranged in the gap space. The width of one non-magnetic isolator is sufficient to cover at least one magnetic pole group to isolate its magnetic field. Under the action of external force, the drive wheel 104 can drive several non-magnetic isolators to rotate in the gap space through the drive shaft 105.

[0045] The generator in this embodiment 1 is a horizontal unit. Several pairs of magnetic pole groups 107 and coil assemblies 106 are arranged radially around the drive shaft 105 to form a horizontal unit structure. A gap is provided between the radially outer side of the magnet assembly and the radially inner side of the coil assembly, and the isolation part 109 protrudes axially and is fixedly installed on the outer periphery of the support 110. In this case, the magnetic leakage port is a cylindrical notch between two adjacent non-magnetic isolators arranged on the cylindrical surface. Figure 8 The image shows 16 magnetic poles (8 pairs of magnetic poles) arranged alternately.

[0046] The axial rear end of the magnetic core 108 is fixedly installed inside the rear housing. This embodiment 1 uses a three-bolt connection as an example; other alternative methods such as snap-fit ​​connections will not be described in detail. A protrusion is provided on the inner side of the axial end of the rear housing, with three through holes evenly arranged on the protrusion. Simultaneously, three threaded holes are provided at the axial rear end of the magnetic core, allowing the bolts to pass through the through holes and be threaded into the threaded holes. In a further preferred and improved embodiment, to strengthen radial limiting and fixation and reduce the support effect of the bolts, a limiting groove 1081 is provided at the axial rear end of the magnetic core. A limiting rod 1021 extending axially forward is provided inside the rear housing 102, and the limiting rod is adapted to the limiting groove. The magnetic core is fitted into the limiting rod through the limiting groove and fixed inside the rear housing by bolt connection.

[0047] The coil assembly 106 is fixedly installed inside the housing and arranged around the outer periphery of the magnet assembly. This embodiment 1 uses a sliding groove limiting snap-fit ​​connection as an example for explanation; other alternative methods such as bolt connections will not be described in detail. A sliding groove is provided on the outer wall of the silicon steel sheet, and a snap-fit ​​protrusion adapted to the sliding groove is provided on the inner wall of both the front housing 101 and the rear housing 102. The coil assembly 106 is fitted into the front housing 101 and the rear housing 102 through the sliding groove and the snap-fit ​​protrusion.

[0048] The axial rear end of the drive shaft 105 is mounted to the axial front end of the magnetic core 108 via a rear bearing 112. Specifically, a rear bearing seat 1082 is provided at the axial front end of the magnetic core 108 to fix the rear bearing. The axial front end of the drive shaft 105 is mounted to the front housing 101 via a front bearing 111. Specifically, a front bearing seat 1011 is provided on the inner side of the axial end of the front housing 101 to fix the front bearing. This embodiment 1 uses this as an example to illustrate the drive shaft mounting position relationship. Other alternative position relationships can be adjusted according to actual needs, and will not be elaborated further.

[0049] The support 110 has a flange-like structure for fixed installation in the middle of the drive shaft. The support 110 is arranged between the axial front end of the magnetic core and the front housing (its axial end). Several non-magnetic isolators protrude axially backward from the outer periphery of the support 110 so that they are located in the gap space (defined as the radial gap space).

[0050] It should be noted that the horizontal generator unit of this embodiment uses a magnetic pole group and coil arranged radially in coordination to generate electricity. The pairing relationship between the magnetic pole group and coil, the coil winding, and the wiring method all employ existing technologies. The following will continue to describe the components of this non-magnetic rotor reluctance generator horizontal unit:

[0051] The rear housing 102 and front housing 101 serve a protective and supportive function. They facilitate heat dissipation, which also protects the insulation of the motor, making them crucial. They reduce noise and vibration, addressing the NVH (Noise, Vibration, and Harshness) issues currently being researched. They prevent dust from entering the generator, preventing injury, and serve as mounting enclosures for wiring and securing magnet fasteners.

[0052] Junction box (103): Wiring and protection circuit, preventing dust from entering the motor and preventing electric current from injuring people.

[0053] Belt pulley (drive wheel 104) or shaft drive: transmits power to enable the generator to operate normally. The belt pulley is connected to the drive wheel of an external drive device via a belt. Under the action of external force from the drive device, the belt pulley drives the generator rotor assembly to rotate.

[0054] Bearings (front bearing 111 and rear bearing 112): Select bearings with good toughness and high temperature resistance, and install them on both sides of the non-magnetic rotor fixing parts to reduce friction during rotation and reduce energy consumption.

[0055] Non-magnetic material rotor (isolation part 109): The non-magnetic material has high density and high strength, and the mechanical loss during rotation is greatly reduced compared with the traditional generator rotor. Through the active influence of the non-magnetic material on the magnetic field, the magnetic field of the coil is changed, thereby achieving the purpose of generating electricity.

[0056] Non-magnetic material rotor fixing component (support 110): Fixes the non-magnetic material rotor (isolation part) and serves as a rotating base.

[0057] Magnet (magnetic pole group 107, including S pole and N pole): The magnet is made of aluminum, iron and copper magnets. It generates a fixed magnetic field in the generator. The non-magnetic rotor of the generator moves in the magnetic field. The movement of the non-magnetic rotor causes the coil to change the magnetic field and generate current.

[0058] Magnet fixing component (magnetic core 108): Fixes the magnet.

[0059] Silicon steel sheets (silicon steel sheet components) and coils (coil assembly 106): Generator silicon steel sheets are a high-quality magnetic material with high permeability, effectively improving the electromagnetic conversion efficiency of generators, reducing energy consumption, and increasing electrical output. Generator silicon steel sheets have high magnetic saturation flux density, can withstand high magnetic field strength, are not prone to saturation, and possess good magnetic stability. Generator silicon steel sheets have good magnetic field permeability, reducing excitation and relaxation losses caused by the magnetic field, thus relatively improving generator efficiency, while also reducing generator operating temperature and noise. Generator silicon steel sheets have good cold manufacturing and hot working properties, and can be easily processed into generator chips of various shapes and specifications to meet the needs of various generators. Generator silicon steel sheets are a widely used, low-cost generator material with high cost-effectiveness, low overall cost, and high recyclability, and are therefore widely used in the generator manufacturing industry. The function of a generator coil is to convert mechanical energy into electrical energy. When the generator's drive shaft rotates, it drives a non-magnetic rotor. During this rotation, the magnetic field of the magnet flows from the N pole to the S pole through the leakage magnetic field of the non-magnetic material, forming an alternating magnetic field loop. The copper conductors in the silicon steel sheet cut the magnetic field lines, generating an electromotive force (EMF). This EMF causes electrons to flow within the coil, thus producing an electric current. The design and manufacture of the generator coil are crucial because the coil's materials and structure directly affect the generator's output power and efficiency. A good generator coil should have low resistance and high conductivity to ensure the generator can produce sufficient current. Furthermore, the generator coil needs sufficient insulation to prevent short circuits or leakage; therefore, the coil is usually encased in insulating material to ensure safe operation.

[0060] As described above, the generator first fixes the assembled magnet assembly and coil assembly inside the rear housing, then installs the rotor assembly on the drive shaft, then installs the drive shaft on the magnetic core, and finally installs the front housing and drive wheel.

[0061] Outside the magnet, the magnetic field lines run from the N pole to the S pole. This invention's generator arranges several pairs of magnetic poles, with their N and S poles alternating, and places a non-magnetic material rotor between the magnet and the coil, isolating it from the magnet's magnetic field. That is, the magnetic field lines cannot penetrate the non-magnetic material rotor, nor attract it, and simultaneously cannot cut the magnetic field lines. The technical principle of this reluctance-free generator is as follows:

[0062] like Figure 16 and Figure 17The diagram shows a schematic of the generator principle of the present invention. It uses an example of a 15-pole group and a rotor consisting of 6 non-magnetic isolators. The N-pole is the shaded area. The 15 pole pairs are arranged around the drive shaft with their N and S poles alternating. The width of the isolator can cover 2 pole pairs, and the width of the magnetic leakage port covers 1 pole. The width of the isolator can cover *a* pole pairs. The magnetic field loop extends from the N-pole through the corresponding magnetic leakage port to the S-pole at a magnetic leakage port spaced 2*a* poles apart on both sides. In this example, the magnetic field loop extends from the N-pole through the corresponding magnetic leakage port to the S-pole at a magnetic leakage port spaced 4 poles apart on both sides.

[0063] See Figure 16 Left image and Figure 17 The diagram above shows state I. A non-magnetic material insulator shields four magnetic poles of equal area: S1N2S2N3, N4S4N5S5. The magnetic field lines of these four poles cannot penetrate the non-magnetic material to reach the silicon steel sheet and coil. At this point, the first N pole (N1, and so on), the third S pole (S3, and so on), and the sixth N pole are all leakage points of the corresponding non-magnetic material insulator. The magnetic field lines travel from the leakage point of the first N pole to the leakage point of the third S pole, and from the leakage point of the sixth N pole to the leakage point of the third S pole, forming a magnetic field loop. This process continues, continuously forming magnetic field loops.

[0064] See Figure 16 The right figure and the lower part of Figure 17 show its II state. The leakage magnetic port at N1 moves clockwise from N1 to S1. At this time, the first N pole is shielded, and the magnetic lines of force will pass through the leakage magnetic port of the fourth N pole and flow to the first S pole, forming a loop. The first alternating magnetic field is completed in the silicon steel sheet and coil (coil assembly). The coil conductor induces the alternating magnetic field and generates the first alternating electromotive force, thereby generating current. And so on, without further explanation.

[0065] As mentioned above, according to Faraday's law, an electromotive force (EMF) is generated whenever a conductor is placed in a changing magnetic field. Thus, driven by an external force (external power), the transmission wheel and transmission shaft rotate, driving the non-magnetic rotor to perform a 360-degree circular motion. This causes a change in the magnetic field of the coil, which in turn causes the generator coil to continuously cut magnetic field lines, forming a moving alternating magnetic field and generating an alternating EMF, thereby producing an electric current.

[0066] Therefore, this generator has a gap space between the magnet assembly and the coil assembly, and several non-magnetic isolators are arranged in this gap space. These non-magnetic isolators successively isolate the magnetic field experienced by the coil during rotation, thereby changing the magnetic field experienced by the coil and generating current. Compared with traditional generators, this non-magnetic rotor reluctance generator has the following characteristics:

[0067] (1) Non-magnetic material insulators are composed of polymer materials, such as rare earth materials extracted from zirconium oxide and plastic products, which can shield and isolate magnetic field lines. They are high in density and light in weight, and have the characteristics of high strength, wear resistance, high temperature resistance and bending resistance. When non-magnetic polymer materials are applied to generators, they have the advantages of high density, high strength and long life.

[0068] (2) The non-magnetic material rotor will neither be penetrated by the magnetic field lines nor attracted by the magnetic field, and it will also be unable to attract the silicon steel sheet corresponding to the area covered by the non-magnetic material rotor.

[0069] (3) When external power is input, the non-magnetic rotor is not affected by the magnetic force of the inner stator magnet, nor by the magnetic resistance generated by the generator load. Therefore, the required input power is very small, and the starting and running speeds are very smooth, achieving the effect of energy saving and emission reduction. It is a reluctance-free generator. The generator uses non-magnetic materials, and the magnet and coil are relatively stationary. The movement of the non-magnetic materials affects the change of the magnetic field in the coil, thereby achieving the purpose of power generation. This greatly improves the efficiency of the generator during operation and achieves the purpose of energy saving and high efficiency by reducing losses.

[0070] (4) Benefits: This non-magnetic material rotor reluctance-free power generation technology can generate exceptionally efficient and stable electrical energy. In a society where energy resources are increasingly scarce, the development and benefit potential of this technology is unprecedentedly vast. This non-magnetic material rotor reluctance-free power generation technology belongs to a new energy power generation method, has no fuel storage limitations, requires very little input power, and has smooth start-up and operation with minimal fluctuations, which is beneficial to the stability of energy supply. This non-magnetic material rotor reluctance-free power generation technology generates no electrical sparks during operation. Because it does not require fuel, it does not pose safety hazards such as fires or explosions, thus ensuring the safety of people's lives and property. This non-magnetic material rotor reluctance-free power generation technology directly utilizes the power of a magnetic field to generate electrical energy. Due to the non-conductive nature of the non-magnetic material, internal energy loss is avoided, resulting in advantages such as high efficiency, environmental friendliness, and safety. Its reliable performance enables the utilization of clean energy.

[0071] (5) Development potential: The non-magnetic material rotor reluctance power generation technology and high temperature superconducting technology can overcome air resistance and mechanical friction resistance in a specially designed low temperature vacuum environment. The addition of polymer non-magnetic material generators gives the non-magnetic material rotor reluctance power generation technology unlimited development potential.

[0072] Example 2

[0073] like Figure 18As shown, the side where the transmission wheel 204 is located is defined as the front side (front end) of the generator, and the opposite side is defined as the rear side (rear end) of the generator. The following descriptions will use the axial, radial, and circumferential directions of the transmission shaft as auxiliary for orientation. In this embodiment 2, the specific structure of each component is not entirely the same as that of the horizontal generator unit in the aforementioned embodiment 1. The power generation principle and effects are not fully explained; please refer to the aforementioned embodiment 1. In this embodiment 2, each component is directly distinguished by reference numerals combined with specific drawings. Alternatively, the '' numerals can be used for distinction. For example, in this embodiment 2, the housing is defined as housing', the magnet assembly as magnet assembly', the coil assembly as coil assembly', the transmission assembly as transmission assembly', the rotor assembly as rotor assembly', the isolation part 209 as isolation part '209', and so on.

[0074] like Figures 18-31 As shown in Embodiment 2, a non-magnetic material rotor reluctance generator includes a housing, a magnet assembly, a coil assembly 206, a transmission assembly, and a rotor assembly. The housing includes a detachably connected front outer shell 201 and a rear outer shell 202. The magnet assembly and the coil assembly 206 are installed inside the housing. The magnet assembly includes a magnetic core 208 and a magnetic pole group 207 arranged on the magnetic core. The coil assembly 206 includes a silicon steel sheet (including a base and a silicon steel sheet body) and a coil group arranged on the silicon steel sheet. The magnetic pole group 207 of the magnet assembly and the coil group of the coil assembly are arranged in a mutually cooperating manner. The transmission assembly includes a transmission wheel 204, a transmission shaft 205, and bearings (including a front bearing 211 and a rear bearing 212). The transmission shaft 205 is rotatably installed inside the housing through the bearings, and the shaft of the transmission shaft 205... A drive wheel 204 is installed at the front end of the front housing (axial end); the rotor assembly includes a support 210 and an isolation part 209. A drive shaft 205 is inserted and fixedly installed at the center of the support 210. The isolation part 209 is fixedly arranged on the outer periphery of the support 210. The isolation part includes several non-magnetic isolators, which are evenly distributed around the drive shaft 205. A magnetic leakage port is provided between two adjacent non-magnetic isolators. A gap space is provided between the magnet assembly and the coil assembly 206. The isolation part 209 is arranged in the gap space. The width of one non-magnetic isolator can cover at least one magnetic pole group to isolate its magnetic field. Under the action of external force, the drive wheel 204 can drive several non-magnetic isolators to rotate in the gap space through the drive shaft 205.

[0075] In this embodiment 2, the generator is a disc-type unit. Several pairs of magnetic pole groups 207 and coil assemblies 206 are arranged axially on the drive shaft 205 to form a disc-type unit structure. A gap is provided between the inner axial sides of the magnet assembly and the inner axial sides of the coil assembly, and the isolation part 209 extends radially and is fixedly installed on the outer circumferential surface of the support. In this case, the magnetic leakage port is a circumferential notch between two adjacent non-magnetic isolators arranged on the circumferential surface. As in embodiment 1, the notch can be formed by directly leaving a gap at the radially outer end of the strip-shaped isolator after it extends radially outward. Alternatively, it can be... Figure 26 and Figure 27 As shown, connect their radial outer ends together.

[0076] The coil assembly 206 has coils arranged at the axial front end of the silicon steel sheet (a disc-shaped base), and the axial rear end of the silicon steel sheet (base) is fixedly installed inside the rear housing 202. This embodiment 2 uses a three-bolt connection as an example; other alternative methods such as snap-fit ​​connections will not be described in detail. A rear protrusion 2021 is provided on the inner side of the axial end of the rear housing 202, with three through holes evenly arranged on the protrusion. Simultaneously, three threaded holes are provided at the axial rear end of the silicon steel sheet (base), allowing bolts to be threaded through the through holes and connected to the threaded holes. A slot is provided at the axial front end of the silicon steel sheet (base), and each coil and silicon steel sheet body is installed in the slot in a petal-like shape, completing the coil assembly.

[0077] The magnetic pole group 207 is arranged at the axial rear end of the magnetic core 208, and the axial front end of the magnetic core 208 is fixedly installed inside the front housing 201. This embodiment 2 is described using a 3-bolt connection as an example; other alternative methods such as snap-fit ​​connections will not be described in detail. A front protrusion 2011 is provided on the inner side of the axial end of the front housing 201, and three through holes are evenly arranged on the front protrusion. At the same time, three threaded holes are provided on the axial front end of the magnetic core 208, and then the bolts are threaded through the through holes and connected to the threaded holes.

[0078] The axial rear end of the drive shaft 205 is mounted to the axial rear end of the silicon steel sheet via a rear bearing 212. Specifically, a rear bearing seat 2061 is provided at the axial rear end of the silicon steel sheet to fix the rear bearing 212. The axial front end of the drive shaft 205 is mounted to the axial front end of the magnetic core 208 via a front bearing 211. Specifically, a front bearing seat 2081 is provided at the axial front end of the magnetic core 208 to fix the front bearing 211. This embodiment 2 uses this as an example to illustrate the installation position relationship of the drive shaft. Other alternative position relationships can be adjusted according to actual needs, and will not be elaborated further.

[0079] The support 210 has a flange-like structure for fixed installation in the middle of the drive shaft. The support 210 is arranged between the magnetic pole group 207 of the magnet assembly and the coil group of the coil assembly 206. Several non-magnetic isolators extend radially outward on the circumferential surface of the support 210 so that they are located within the gap space (defined as the axial gap space).

[0080] It should be noted that the horizontal generator unit in this embodiment 2 uses a magnetic pole group and coil arranged radially in coordination to generate electricity. The pairing relationship between the magnetic pole group and coil, the coil winding, and the wiring method all employ existing technologies. The following will continue to describe the components of this non-magnetic rotor reluctance generator disc unit:

[0081] Front housing 201 and rear housing 202: These serve a protective and supportive function. They facilitate heat dissipation, which also protects the insulation of the motor, making them crucial. They reduce noise and vibration, addressing the NVH (Noise, Vibration, and Harshness) issues currently being researched by many. They prevent dust from entering the generator, preventing injury, and serve as mounting housings for wiring and securing magnet fasteners.

[0082] Junction box 203: Protects the circuit from dust entering the motor and prevents injury.

[0083] Pulley: Transmits power, enabling the generator to operate normally. Driven by the belt, the pulley drives the generator rotor to rotate.

[0084] Rotating shaft (drive shaft 205): Used to fix non-magnetic materials and to function as a rotating shaft.

[0085] Bearings (front bearing 211 and rear bearing 212): Select bearings with good toughness and high temperature resistance, and install them on both sides of the non-magnetic material fixing parts to reduce friction during rotation and reduce energy consumption.

[0086] Magnet fastener (magnetic core 208): Fixes the magnet and the bearing.

[0087] Magnet (magnetic pole group 207, including S pole and N pole): The magnet generates a fixed magnetic field in the generator. The non-magnetic rotor of the generator moves in the magnetic field. The movement shielding and isolation effect of the non-magnetic material causes the coil to change the magnetic field and generate current.

[0088] Non-magnetic material rotor (isolation part 209): Non-magnetic materials (such as rare earth material extracted zirconium oxide and plastic product extracts) have high density and high strength. During rotation, the mechanical loss is greatly reduced compared with traditional generator rotors. Through the active influence of non-magnetic materials on the magnetic field, the magnetic field of the coil is changed, thereby achieving the purpose of generating electricity.

[0089] Silicon steel sheet (silicon steel sheet body) and coil (forming coil assembly 206 with base):

[0090] Silicon steel sheets for generators are a high-quality magnetic material with high permeability, effectively improving the electromagnetic conversion efficiency of generators and reducing energy consumption. They possess high magnetic saturation flux density, can withstand high magnetic field strength, are not prone to saturation, and exhibit good magnetic stability. Their excellent magnetic field permeability reduces excitation and relaxation losses, thus improving generator efficiency and lowering operating temperature and noise. Silicon steel sheets also have good cold-manufacturing and hot-working properties, allowing them to be easily processed into various shapes and specifications to meet the needs of diverse generators. As a widely used, low-cost motor material, silicon steel sheets offer high cost-effectiveness, low overall cost, and high recyclability, making them widely applicable in the generator manufacturing industry.

[0091] The function of a generator coil is to convert mechanical energy into electrical energy. When the generator rotor rotates, it drives an electromagnet to rotate. During this rotation, the electromagnet's magnetic field cuts through the generator coil, creating a potential difference. This potential difference causes electrons to flow within the coil, thus generating an electric current. The design and manufacture of the generator coil are crucial because the coil's materials and structure directly affect the generator's output power and efficiency. A good generator coil should have low resistance and high conductivity to ensure the generator can produce sufficient current. Furthermore, the generator coil needs sufficient insulation to prevent short circuits or leakage. Therefore, the coil is typically encased in insulating material to ensure safe operation.

[0092] Silicon steel sheet fastener (base): Used to fix silicon steel sheets.

[0093] As described above, the generator first mounts the rotor assembly onto the drive shaft. Then, the assembled magnet assembly and coil assembly are fixedly mounted on the drive shaft on either side of the rotor assembly. Next, the coil assembly and drive shaft are installed inside the rear housing, followed by the front housing, and finally the drive wheel. Driven by external force, the drive wheel and drive shaft rotate, propelling the non-magnetic rotor in a 360-degree circular motion. This causes changes in the coil's magnetic field, resulting in the generator coil continuously cutting magnetic field lines, creating a moving alternating magnetic field, generating an alternating electromotive force, and thus producing current. When external power is input, because the non-magnetic rotor is unaffected by the magnetic force of the inner stator magnet or the magnetic resistance generated by the generator load, the required input power is very small, resulting in smooth start-up and operation, achieving energy saving and emission reduction. It is a reluctance-free generator.

[0094] Based on the foregoing example, in an improved example, see [link to example]. Figure 26 and Figure 27The isolation section 209 also includes a non-magnetic sealing section. The axial rear end of the non-magnetic sealing section is located at the radial outer end of a plurality of non-magnetic isolators, and the axial front end of the non-magnetic sealing section protrudes forward along the axial direction to surround the outer periphery of the magnetic pole group. In this way, it can enhance the strength and isolation effect.
