Description

Technical Field

[0001] This invention relates to a low-loss, high-coupling electromagnetic induction generator, and more specifically, to a low-loss generator with an asymmetric magnetic induction path that improves energy conversion efficiency by optimizing the rotor and stator structures to reduce resistance during the electromagnetic induction process. Background Technology

[0002] The principle of a generator is based on Ampere's law and Faraday's law of electromagnetic induction, namely, the interaction between a magnetic field and a conductor generates an electromotive force (EMF). The basic structure of a traditional generator includes an armature coil and a contactor coil, which generate EMF by alternately passing the positive terminal. However, traditional generators have low efficiency, with an energy conversion efficiency of only 30% to 40%. This is mainly because the interference force generated by the armature coil reduces the generator rotor speed. Furthermore, energy losses such as heat loss occur during actual power generation, further reducing efficiency.

[0003] To improve power generation efficiency, various technologies are being developed both domestically and internationally. Some literature has disclosed methods to improve generator efficiency, but these methods still have room for improvement. Summary of the Invention

[0004] This invention aims to improve the energy conversion efficiency of a generator by reducing resistance during the electromagnetic induction process. Specifically, this invention improves power generation efficiency by optimizing the structural design of the rotor and stator to reduce interference forces generated when current flows through the stator coils.

[0005] According to one objective of the present invention, a low-loss, high-coupling electromagnetic induction generator is provided, comprising:

[0006] The rotor coil (100) includes a stator coil (110), a rotating plate (120), a connecting plate (130), a rotating shaft insertion part (150), and a rotor rotating hole (160); the stator coil (200) includes an outer stator coil (201), an inner stator coil (202), an induction coil (210), and an induction coil insertion slot (220); the rotating shaft (300) is used to drive the rotor coil (100) to rotate; wherein, the stator coil (110) is used to generate magnetic force by rotation, and the N pole and S pole of adjacent stator coils (110) are arranged to cross each other; the rotating plate (120) is made of aluminum and includes a rotating shaft insertion part (150) at its center for interlocking with and rotating the rotating shaft (300), and the center of the rotating plate (120) also includes three rotor rotating holes (160) to reduce centripetal force and steering force.

[0007] Furthermore, the stator coil (110) is composed of two layers, including an upper stator coil (110a) and a lower stator coil (110b), and the excitation directions of the upper stator coil (110a) and the lower stator coil (110b) are opposite.

[0008] Furthermore, the outer stator coil (201) and the inner stator coil (202) are each composed of two layers, including an upper outer stator coil (201a) and a lower outer stator coil (201b), as well as an upper inner stator coil (202a) and a lower inner stator coil (202b).

[0009] Furthermore, the induction coil insertion slot (220) is a rhomboid structure used to accommodate the induction coil (210), which is used to generate electromagnetic force through the rotation of the rotor coil (100).

[0010] Furthermore, the outer stator coil (201) and the inner stator coil (202) each include 24 induction coils (210).

[0011] Furthermore, the rotating plate (120) also includes a fastener (140) for fixing the stator coil (110) between the rotating plate (120) and the connecting plate (130) to prevent the stator coil (110) from detaching due to centrifugal force during rotation.

[0012] Furthermore, the outer stator coil (201) and the inner stator coil (202) are connected by fasteners (231, 232). When the stator coil (200) is arranged in a double layer, the fastening portion (231) of the outer stator coil (201) and the fastening portion (232) of the inner stator coil (202) can be fastened to couple the outer stator coil (201) and the inner stator coil (202).

[0013] Furthermore, the rotating shaft (300) is connected to a motor for driving the rotor coil (100) to rotate.

[0014] Furthermore, the rotor rotation hole (160) is used to reduce the centrifugal force and steering force generated when the rotor coil (100) rotates, thereby reducing energy loss.

[0015] According to another objective of the present invention, the present invention provides a method of using the above-described low-loss generator with an asymmetric magnetic induction path, comprising the following steps:

[0016] S1: The rotor coil (100) is installed in the internal space of the stator coil (200);

[0017] S2: Insert the rotating shaft (300) into the rotating shaft insertion portion (150) of the rotating plate (120).

[0018] S3: The rotating shaft (300) is driven to rotate by the motor, thereby driving the rotor coil (100) to rotate;

[0019] S4: Electromagnetic force is generated by the rotation of the rotor coil (100), which is induced by the induction coil (210) in the stator coil (200) and converted into electrical energy.

[0020] Furthermore, during the rotation of the rotor coil (100), the N pole and S pole of the stator coil (110) are arranged in a cross pattern to reduce resistance during electromagnetic induction and improve energy conversion efficiency.

[0021] The technical solution of this invention optimizes the structural design of the rotor and stator, utilizes double-layer stator coils and cross-arranged magnetic poles to reduce energy loss during electromagnetic induction, and significantly improves the energy conversion efficiency of the generator. The overall structure is compact, suitable for various application scenarios, and has advantages such as high efficiency, low loss, and simple structure. Attached Figure Description

[0030] Figure 2 A combined configuration of a low-loss generator structure with an asymmetric magnetic induction path for implementing the present invention is shown. In detail, Figure 2 (a) is the entire structure; Figure 2 (b) shows the side structure of the composite structure. Figure 2 (b) shows a top view of the entire composite structure.

[0031] like Figure 2 As shown, the present invention includes a rotor coil 100, a stator coil 200, and a rotating shaft 300. The rotor coil 100, the stator coil 200, and the rotating shaft 300 may be housed in a housing 1. To facilitate understanding of the structure of the present invention, the structure of the stator coil (200) will be described first.

[0032] Figure 3 This is a plan view of the structure of stator coil 200. Figure 4 This is a perspective view of stator coil 200.

[0033] like Figure 3 and Figure 4 As shown, the stator coil 200 includes an outer stator coil 201, an inner stator coil 202, an induction coil 210, an induction coil insertion slot 220, an induction coil insertion slot protrusion 221, and fastening portions 231 and 232. The stator coil 200 mainly includes an outer stator coil 201 disposed outside the rotor coil 100 and an inner stator coil 202 disposed inside the rotor coil 100. The outer stator coil 201 is cylindrical and includes one or more induction coil insertion slots 220 on its inner side. The outer stator coil 201 can be constructed in two layers and can include an upper outer stator coil 201a and a lower outer stator coil 201b with the same structure. The induction coil insertion slot 220 is a space for accommodating the induction coil 210, which generates electromagnetic force through the rotation of the rotor coil 100.

[0034] like Figure 3 As shown, the induction coil 210 is included in the induction coil insertion slot 220 inside the outer stator coil 201. With its diamond-shaped structure, the induction coil insertion slot 220 can be configured such that the induction coil 210 will not disengage when the rotor coil 100 rotates.

[0035] In addition, the outer edge of the induction coil insertion slot 220 may include an induction coil insertion slot protrusion 221 to prevent the induction coil 210 from dislodging.

[0036] In an embodiment of the present invention, the inner side of an outer stator coil 201 includes 24 induction coil insertion slots 220, each induction coil insertion slot 220 including an induction coil 210. An outer stator coil 201 may include 24 induction coil insertion slots 220 and 24 induction coils 210. The inner stator coil (202) is cylindrical and includes one or more conductive disk insertion slots (220) on its outer side. The inner stator coil 202 may be constructed in two layers, including an upper inner stator coil 202a and a lower inner stator coil 202b. The induction coil insertion slots 220 are spaces for accommodating induction coils 210, which are used to generate electromagnetic force through the rotation of the rotor coil 100.

[0037] like Figure 3 As shown, the induction coil 210 is included in the induction coil insertion slot 220 outside the inner stator coil 202. The induction coil insertion slot 220 is configured with a rhomboid structure such that the induction coil 210 does not disengage when the rotor coil 100 rotates. At this time, the rhomboid direction of the guide coil insertion slot (220) of the outer stator coil (201) is symmetrical to the rhomboid direction of the guide coil insertion slot (220) of the inner stator coil (202), such as when rotated 180°.

[0038] In addition, the outer edge of the induction coil insertion slot 220 may include an induction coil insertion slot protrusion 221 to prevent the induction coil 210 from dislodging.

[0039] In this embodiment of the invention, the outer side of an inner stator coil 202 includes 24 induction coil insertion slots 220, each induction coil insertion slot 220 including an induction coil 210, and the inner stator coil 202 includes 24 induction coils. It may include insertion slots 220 and 24 induction coils 210. The upper side of the outer stator coil 201 may include one or more fasteners 231. Furthermore, the upper side of the inner stator coil 202 may include one or more fasteners 232.

[0040] like Figure 2 As shown in (a), the fastening part 231 of the outer stator coil 201 and the fastening part 232 of the inner stator coil 202 are connected together, thereby maintaining their shape by the binding force when the rotor coil 100 rotates.

[0041] Furthermore, when the outer stator coil 201 and the inner stator coil 202 are arranged in a double layer, the fastening portion 231 of the outer stator coil 201 and the fastening portion 232 of the inner stator coil 202 can be fastened.

[0042] Figure 5 It is a planar structure of the rotor coil according to an embodiment of the present invention. Figure 5 (a) is a plan view of the rotor coil. Figure 5 (b) is a side view of the rotor coil. Figure 6 This is a perspective view of the rotor coil according to an embodiment of the present invention. Figure 6 (a) is a perspective view of the rotor coil. Figure 6 (b) is a side view of the rotor coil.

[0043] like Figure 5 and 6 As shown, the rotor coil 100 may include a stator coil 110, a rotating plate 120, a connecting plate 130, a fastening portion 140, a rotating shaft insertion portion 150, and a rotor rotation hole 160. The rotor coil 100 includes a stator coil 110 located above the rotating plate 120. The rotating plate 120 is used to rotate in the space between the outer stator coil 201 and / or the inner stator coil 202 to generate electromagnetic force. The measuring coil 110 is used to generate magnetic force and may use a permanent magnet.

[0044] The relay coil 110 can be composed of two layers, including an upper relay coil 110a and a lower relay coil 110b. In this case, the lower ranging coil 110b can be fixed on the upper part of the rotating plate 120, and the upper ranging coil 110a can be fixed on the upper part of the coupling plate 130.

[0045] like Figure 5 As shown in (a), the rotating plate 120 may have a stator coil 110 in its upper part within a housing aligned with the rotation angle. Preferably, the rotating plate 120 and the connecting plate 130 for fixing the measuring coil 110 are made of aluminum. Furthermore, the center of the rotating plate 120 includes a rotating shaft insertion portion 150 through which a rotating shaft 300 passes. The rotating shaft 300 can be connected to a motor to rotate the rotating plate 120.

[0046] like Figure 5 As shown in (b), since the stator coil 110 is mounted on the housing of the rotating plate 120, the rotor coil 100 can be connected to the top of the upper stator coil 110a via the connecting plate 130 to prevent it from detaching due to centrifugal force during rotation. If the stator coil 110 is secured between the connecting plate 130, which includes the upper stator coil 110a and the lower stator coil 110b, and the rotating plate 120 via the fastening part 140 including the stator coil 110, the stator coil 110 can be prevented from detaching due to centrifugal force even during rotation.

[0047] Furthermore, the connecting plate 130 may also include protrusions extending outward toward the outer side of the outer stator coil 201 and inward toward the inner side of the inner stator coil 202 to prevent the stator coil 110 from deviating outward during rotation. The fastener 140 is located outside the outer stator coil 201 to prevent interference with the generation of electromagnetic forces due to rotation.

[0048] Preferably, they are fastened in the direction between each stator coil 110, rather than in the internal direction of the inner stator coil 202. Figure 7 The stimulation direction is shown when the measuring coil 110, which is located on the upper part of the rotating plate 120, is placed.

[0049] like Figure 7 As shown, the rotating plate 120 can be arranged such that one or more instrument coils 110 are rotated at an angle relative to the housing area. When the stator coils 110 are rotated by the rotating plate 120 via the rotating shaft 300, the outer stator coil 201 and the inner stator coil 202 can rotate in space.

[0050] At this point, when the coils 110 are arranged adjacent to each other, the N and S poles can be arranged in a staggered manner. This arrangement can reduce the resistance generated when electromagnetic force is produced by rotation.

[0051] In addition, such as Figure 7 and Figure 5 As shown in (b), the ranging coil 110 can be composed of two layers, including an upper ranging coil 110a and a lower ranging coil 110b. In this case, the lower measuring coil 110b can be fixed on the upper part of the rotating plate 120, and the upper measuring coil 110a can be fixed on the upper part of the coupling plate 130.

[0052] Furthermore, the contactor coil 110 can be formed into a double layer by pairing an even number of coils (e.g., 2, 4, 6, etc.). In this case, as... Figure 7 As shown, when the excitation direction of the upper scale coil 110a is N→S, the excitation direction of the lower scale coil 110b can be configured as S→N. That is, the excitation directions of the upper relay coil 110a and the lower relay coil 110b can intersect in opposite directions. This arrangement can reduce the resistance generated when electromagnetic force is produced by rotation.

[0053] In an embodiment of the invention, each of the outer stator coil 201 and the inner stator coil 202 consists of 24 coils. The corresponding stator coils 110 are arranged such that every three outer stator coils 201 and inner stator coils 202 correspond to one stator coil.

[0054] More specifically, it consists of stator coils 110 of length corresponding to two of the three outer stator coils 201 and the inner stator coils 202, with the remaining one of the outer stator coils 201 and the inner stator coil 202 configured not to have a stator coil 110 placed on it. That is, in an embodiment of the invention, the outer stator coils 201 and the inner stator coils 202 consist of 24 units, and eight stator coils 110 are arranged on a turntable 120, such that one stator coil 110 can correspond to the three outer stator coils 201 and the inner stator coils 202. Thus, the upper stator coil 110a and the lower stator coil 110b correspond to the upper outer stator coil 201a and the lower outer stator coil 201b.

[0055] In addition, in the same manner, the upper stator coil 110a and the lower stator coil 110b correspond to the upper inner stator coil 202a and the lower inner stator coil 202b.

[0056] like Figure 5 As shown in (a), the rotating plate 120 may include a rotating hole 160 centered relative to the rotating shaft insertion portion 150. In embodiments of the invention, three rotor rotating holes 160 are included. The rotor rotating holes (160) reduce the centrifugal force and directional force generated when the stator coils (110) rotate. In other words, when a disk such as the rotating plate 120 rotates, centrifugal force and directional force are generated, resulting in rotational resistance. This resistance ultimately leads to energy loss.

[0057] To reduce this loss, a rotor 160 is included. A rotating shaft 300 can be inserted into a rotating shaft insertion portion 150 of a rotating plate 120 to rotate the rotor coil 100. The rotating shaft 300 is connected to a motor, and the rotor coil 100 can be rotated by rotating the rotating shaft 300.

[0058] Figure 8 This is an exploded perspective view showing the arrangement process of the rotor coil and stator coil of the present invention.

[0059] Figure 8 The structure of a stator coil 110, an outer stator coil 201, and an inner stator coil 202 is shown, but the structure of the upper stator coil 110a, the upper outer stator coil 201a, and the upper inner stator coil 202a is the same as the structure of the lower stator coil 110b, the lower outer stator coil 201b, and the lower inner stator coil 202b.

[0060] like Figure 2 and Figure 8 As shown, the rotor coil 100 is disposed in the internal space of the stator coil 200 and is rotatable.

[0061] More specifically, when the rotating plate 120 of the rotor coil 100, which is contained in the internal space between the outer stator coil 201 and the inner stator coil 202, rotates, an electromagnetic force is generated by the induction coil 210 contained in the induction coil insertion slot 220 and the stator coil 110 above the rotating plate 120. To confirm the effect on the generator according to an embodiment of the present invention, the inventors of the present invention measured the electrical current during the rotational movement of the motor interlocked with the rotating shaft 300.

[0062] The resistance and current of the machine.

[0063] (1) The resistance measured when the motor is rotated without a generator (stator coil (200) and rotor coil (100)) is 40.0 Ω, and the current is [missing value].

[0064] 5.4 A.

[0065] (2) When the outer stator coil (201) and the rotor coil (100) rotate in conjunction with the motor, the measured resistance value is 40.1 Ω and the current value is 5.4 A.

[0066] (3) It consists of an outer stator coil (201) and an inner stator coil (202). When the rotor coil (100) rotates in conjunction with the motor, the measured resistance value is 40.0 Ω and the current value is 5.4 A.

[0067] Therefore, in this invention, when the rotor coil 100 rotates by the motor to generate electromagnetic force, when it rotates only by the outer stator coil 201, and when it rotates by the outer stator coil 201 including the inner stator coil 202, it is confirmed that the current value and resistance value do not change significantly, and power loss can be minimized.

[0068] In the foregoing description, the present invention has been shown and described in conjunction with embodiments. However, those skilled in the art will readily understand that various modifications and variations can be made without departing from the spirit and scope of the invention as shown in the claims.
