Abstract

To provide a stator core configured to substantially reduce the effects of electromagnetic braking, thereby improving power generation efficiency, and to provide a power generation system that can embody such a stator core to improve power generation efficiency, it is disclosed herein that a stator core for generating electricity by magnetic induction or electromagnetic induction includes a core and a wire wound around the core, the wire being wound in a winding direction to form a plurality of wire intersections.

Description

[Technical field]

[0001] The present disclosure relates to power generation, and more particularly, to stator cores for power generation systems. [Background technology]

[0002] Power generating systems that utilize the conversion of mechanical energy typically include a rotor and a stator system. The stator is known to have one or more stator cores, each made by winding an electrically inductive wire around a magnetic core or core. Operation of such a generator induces a magnetic field that creates a reaction force that acts against the direction the rotor is trying to move, slowing the generating rotation. This "electromagnetic braking" causes a loss of mechanical energy input to the system, reducing the efficiency of the generator.

[0003] Many publications have proposed attempts to improve the power output of generators. For example, US Patent Application Publication No. 2010 / 019,608-A1 proposes a stator with multiple parallel wire slots on the inside to provide a larger induction area and thus avoid magnetic saturation. US Patent Application Publication No. 2006 / 290,224-A1 discloses a generator consisting of two or more permanent magnets spaced apart at a predetermined distance with opposite poles facing each other. Furthermore, US Patent No. 9,584,056-B2 provides a multi-phase multi-coil generator to address the problem of a narrow optimal rotational speed range, which reduces the power generation efficiency.

[0004] None of the above effectively addresses the problem of electromagnetic braking. Summary of the Invention [Problem to be solved by the invention]

[0005] A concept of the present disclosure relates to providing a stator core configured to substantially reduce the effects of electromagnetic braking, thereby improving power generation efficiency. Another concept of the present disclosure relates to providing a power generation system in which such a stator core can be implemented to improve power generation. Accordingly, the present disclosure provides embodiments illustrating aspects and enablement of such concepts. Preferred embodiments are described in detail below. [Means for solving the problem]

[0006] Unless otherwise specified, the term "electromagnetic brake" as referred to in this specification is intended to mean a reaction force that acts against the direction in which the rotor of the generator attempts to move, thereby reducing the generating rotation.

[0007] Unless otherwise indicated, certain terms are used in the following description for general descriptive purposes only and should not be construed as limiting the scope of the concepts of the present disclosure in any manner. Similarly, any specific configurations, figures, and dimensions herein are for illustrative purposes only and should not be construed as limiting the scope of the concepts of the present disclosure.

[0008] In a first aspect, one embodiment is a stator core for generating electricity by magnetic or electromagnetic induction, the stator core including a core and a wire wound around the core, the wire wound in a winding direction to form a plurality of wire intersections.

[0009] In a second aspect, one embodiment is a stator for generating electricity by magnetic induction or electromagnetic induction, the stator having at least one stator core and a stator core holder. For The stator core includes a core and a wire wound around the core, the wire being wound in a winding direction to form a plurality of wire intersections.

[0010] In a third aspect, an embodiment is a system for generating electricity by magnetic or electromagnetic induction, the system including at least one rotor and at least one stator. (i) The rotor is configured to be rotatable about an axis and includes at least one magnet, which may be a permanent magnet or an electromagnet. (ii) The stator is configured to be stationary and includes at least one stator core, the stator core including a core and a wire wound around the core, the wire being wound in a winding direction to form a plurality of wire intersections. The system is configured to receive mechanical energy to rotate the rotor about the axis. Optionally, the stator has at least one receptacle for holding the stator core.

[0011] Embodiments according to the first, second and third aspects above may be configured such that each wire intersection forms two pairs of opposing angles, where each angle of the first pair is designated p and each angle of the second pair is designated q, where p faces generally away from the winding direction and q faces generally along the winding direction.

[0012] Preferably, the angle p is 90 degrees.

[0013] Additionally, the nucleus of the embodiment is preferably non-magnetizable, and more preferably is an air core.

[0014] The embodiment according to the second or third aspect above may preferably be configured such that the receptacle of the embodiment has a substantially symmetrical shape. Although the receptacle of this embodiment may be formed from a wide variety of materials, the receptacle is preferably formed from an electrically insulating material, and more preferably from molded fiberglass.

[0015] In embodiments according to the second or third aspect above, the stator is for generating one or more electrical phases and preferably includes a plurality of stator cores. More preferably, the number of such plurality of stator cores is a multiple of the number of electrical phases intended to be generated. Also, when the receptacle of such embodiment is for holding a plurality of stator cores, such receptacle is preferably configured to hold the plurality of stator cores such that the positions of the stator cores are evenly distributed. Furthermore, the plurality of stator cores are electrically connected in a pair, multiple pairs, or an odd number.

[0016] In an embodiment according to the third aspect above, the system is for generating one or more electrical phases, and the rotor preferably comprises a plurality of magnets. More preferably, such a plurality of magnets (N RM The number of digits is determined by rounding up the product of the following expression:

[0017]

number

[0018] Preferably, the magnet and nucleus / nuclei have approximately the same cross-sectional dimensions.

[0019] It is also preferred that the system includes multiple stators and / or multiple rotors. More preferably, the system includes multiple stators and / or multiple rotors, such multiple stators and rotors being aligned coaxially, alternating and without direct contact.

[0020] In one embodiment according to the third aspect above, it is also preferable to configure the rotors and stators and their alignment such that at any instance during intended operation, each stator core is exposed to the rotor magnets. This is desirably made possible by configuring (i) a first imaginary circle having a perimeter within which the centers of all the stator cores are located, and (ii) a second imaginary circle having a perimeter within which the centers of all the rotor magnets are located, to have approximately the same size, and by aligning the rotors and stators such that the first and second imaginary circles are concentric.

[0021] The embodiment according to the third aspect above may be configured such that the rotor includes a plurality of magnets. In such a case, the number of magnets in the rotor preferably varies with the number of stator cores in the stator and a factor dependent on the number of electrical phases intended to be generated. More preferably, the calculation is expressed as follows:

[0022]

number

[0023]

number

[0024] Example calculations: for two-phase generation, C is 1+1 / 2=1.5, for three-phase generation, C is 1+1 / 3=1.33, for four-phase generation, C is 1+1 / 4=1.25, etc.

[0025] As a further example, if three stator cores are held by the receptacle of a three-phase generating stator, C is 1.33, and therefore the preferred number of magnets in the rotor is NRM = 1.33 × 3 = 3.99, rounded up to 4 magnets per rotor. Similarly, if six stator cores are held by the stator receptacle for three-phase generation, C is 1.33, so the preferred number of magnets in the rotor is N RM = 1.33 x 6 = 7.98, rounded up to 8 magnets per rotor, and so on.

[0026] In an embodiment according to the third aspect above, when implementing the preferred number of magnets according to equation (1) (or equivalently, equation (2) together with equation (3)), the preferred diameter of the stator core varies with the diameter of the magnets. More preferably, the calculation is expressed as follows:

[0027]

number

[0028]

number

[0029] For example, when using a magnet with a diameter of 30 mm for three-phase power generation (C=1.33), the inner diameter of the stator core is preferably D SC、I =D RM = 30 mm. The outer diameter of the stator core is preferably D SC,O,max =2×1.33×30=79.8mm or less.

[0030] Furthermore, for example, when using a magnet with a diameter of 30 mm for four-phase power generation (C=1.25), the inner diameter of the stator core is preferably D SC、I =DRM = 30 mm. The outer diameter of the stator core is preferably D SC,O,max =2×1.25×30=not larger than 75mm.

[0031] Furthermore, the thickness of the stator core can be varied to produce any phase type of electricity. SC、I Or D RM It is preferable that it is smaller than .

[0032] In embodiments according to the third aspect above, it is also preferred to align the rotor and stator such that during intended operation, all stator cores in the receptacles of the same stator are exposed to the same magnetic polarity at the same instance in order to generate electricity of the same phase. In embodiments where multiple stators are coaxially aligned, this is preferably made possible by locating stator cores for generating the same electrical phase in a first position (or set of first positions) of a preceding stator and a second position (or set of second positions) of a succeeding stator, the second position / set of positions forming an angular displacement from the first position / set of positions. In embodiments where more than one stator is coaxially aligned, such angular displacement is preferably increased from one stator to the next. In such cases, the increment of angular displacement is more preferably expressed as:

[0033]

number

[0034] For example, if the preferred number of magnets in the rotor is eight, and to achieve that number, the preferred increment of angular displacement from one stator to the next is θ = 360° / 8 = 45 degrees. This means that the stator cores for producing an electrical phase in any stator are positioned 45 degrees apart from the stator cores for producing the same electrical phase in an adjacent stator.

[0035] In embodiments according to the third aspect above in which there are multiple magnets per rotor, the magnets are preferably positioned such that, viewed from each face of the rotor, any one of the magnets has a polarity opposite to that of the adjacent magnets.

[0036] Embodiments according to the concepts of the present disclosure can be adjusted within the same concept to accommodate either series or parallel connections.

[0037] In order to better understand the technical concepts, preferred embodiments of the aspects are described in detail, by way of non-limiting examples only, with reference to the accompanying drawings. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0039] Please note that the following description is provided to illustrate preferred embodiments and is provided by way of example only. Any specific configurations, figures, and dimensions herein are for illustrative purposes only and should not be construed as limiting the scope of the concepts of the present disclosure.

[0040] FIG. 1A illustrates one embodiment of a power generating stator core 100 according to an aspect of the inventive technical concept. In the preferred embodiment, the stator core 100 is constructed from a solid copper stator core wire 102 having a circular cross section with a diameter of 0.32 mm. Said construction is achieved by winding the stator core wire 102 around a core. Such a core is preferably a non-magnetizable core, since a magnetizable core may cause additional electromagnetic braking during intended rotation. In the preferred embodiment, the core is an air core 104 around which layers of the stator core wire 102 are wound to form a substantially cylindrical spool 106. Here, the diameter defined by the opening provided by the air core 104 is D SC、I The “inner diameter” of the stator core 100 is expressed as D SC、O In a preferred embodiment, D SC、I = 30 mm, D SC、O = 70 mm, and the thickness of the stator core 100 is 12 mm. Additionally, the stator core wire 102 is wound to form multiple wire intersections 108 along the length of the same stator core wire 102 forming the same spool 106. To achieve the stator core wire 102 forming a plurality of wire intersections 108, a manufacturing method of the stator core is used. The method includes, in its configuration, winding, preferably successively alternating, two or more independent magnetizable wires (i.e., the stator core wires 102) in opposite directions (one clockwise, the other counterclockwise) until the spool 106 is finished, i.e., alternating a turn of the first wire wound clockwise with the next turn of the second wire wound counterclockwise. All of the above windings start at the center and / or bottom of the spool 106 and end with two wires 102 on the surface of the spool 106. These wires 102 are initially coupled so that they have electrical continuity when the spool 106 is magnetically induced.

[0041] FIG. 1B shows further details regarding the formation of wire intersections 108 according to a preferred embodiment. In particular, FIG. 1B shows an insulation layer 110 formed from the windings of the stator core wire 102. In a preferred embodiment, multiple insulation layers 110 are stacked concentrically around the air-core 104 (not shown in FIG. 1B) to form the spool 106 according to FIG. 1A above. Here, the stator core wire 102 is wound toward a predetermined winding direction 112 such that the stator core wire 102 is cross-woven within the same layer 110 to form the wire intersections 108. In this preferred embodiment, a clockwise turn has an equivalent number of counterclockwise turns, as shown in FIG. 1B.Regardless, wire intersections 108 according to the concepts of the present disclosure may be formed by different winding techniques, which are described below as examples of alternative embodiments.

[0042] 1B, each wire intersection 108 forms two pairs of opposing angles, with each angle of the first pair designated p and each angle of the second pair designated q, where p faces generally away from the winding direction 112 and q faces generally along the winding direction 112. Wire intersections 108 may be configured to form angles p and q of any size. However, according to a preferred embodiment, the wire intersections 108 form angles p and q having a magnitude of approximately 90 degrees.

[0043] In a preferred embodiment, the stator core 100 according to Figures 1A and 1B forms part of a power generating stator 200. Figure 2 shows a further aspect of the preferred embodiment, where the stator 200 includes a stator core receptacle 202 for holding the stator core 100 such that the positions of the stator core 100 are evenly distributed. The stator core receptacle 202 according to the preferred embodiment is formed from molded fiberglass to have a disk outline with a generally circular stator central hole 204 for contactless insertion of a shaft 404 (not shown in Figure 2; described below). The stator core receptacle 202 is further configured to hold the stator core 100 by providing an equal number of stator core slots 206 defined by openings to the stator core receptacle 202, axes of the stator core slots 206, and the stator central holes 204 that are generally parallel. The dimensions of the stator core slots 206 are configured to allow sufficient insertion of the stator core 100. The stator core slots 206 in a preferred embodiment are positioned on the stator core receptacle 202 so that when all of the stator core slots 206 are filled with the stator cores 100 and all of the stator cores 100 are held by the stator core receptacle 202 as intended, the stator core receptacle 202 can hold the stator cores 100 near the edges of the stator core receptacle 202 in a manner such that the stator 200 is substantially symmetrical. Each stator core 100 may be permanently or temporarily coupled or fastened to each corresponding stator core slot 206. In a preferred embodiment, the stator core 100 is permanently coupled to the inner surface of the stator core slot 206 by embedding the stator core 100 in the stator core receptacle 202 during a fiberglass molding process at a predetermined location in the stator core slot 206. Additionally, the stator core receptacle 202 in this embodiment has six peripheral holes 208 (not shown in FIG. 2; described below) for contacting and inserting the auxiliary rods 406.

[0044] 2, one stator 200 is preferably configured to hold three pairs of stator cores 100 for the purpose of generating three-phase electricity. It should be noted that the number of stator cores 100 per each stator 200 in other embodiments not shown here can be an odd or even number less than or greater than six. Such number depends directly on the number of electrical phases intended without departing from the concepts of the present disclosure.

[0045] It should be further noted that when the stator cores 100 are held by the stator core receptacles 202 as intended for the preferred embodiment, a "pair" of the stator cores 100 means that each of the two stator cores 100 is disposed in the two stator core slots 206 that are furthest from each other on the same stator core receptacle 202. Figure 2 illustrates the concept of pairing by representing two stator cores 100 that belong to the same pair with capital letters "A," "B," and "C."

[0046] In a preferred embodiment, each bare stator core 100 is electrically connected by placing a bond wire 210 in contact with both stator cores 100 of the same bare. In this embodiment, the bond wire 210 has a larger diameter than the stator core wires 102. As mentioned above, the number of stator cores 100 directly corresponds to the number of electrical phases intended to be generated by the embodiment. FIG. 2 shows the preferred connection of each pair of stator cores 100, with the "A" pair being for generating a first phase of electricity, the "B" pair being for generating a second phase of electricity, and the "C" pair being for generating a third phase of electricity.

[0047] FIG. 3A shows a part of yet another aspect of the preferred embodiment. Here, five stators 200 have stator cores 100 inserted and joined into all stator core slots 206 as intended. The five stators 200 are coaxially aligned and fixed by inserting auxiliary rods 406 through the peripheral holes 208 of the stator core receptacles 202. In the preferred embodiment, there are six auxiliary rods 406 (one of the six is ​​omitted from FIG. 3A). Meanwhile, the shaft 404 is positioned to protrude through the central holes 204 of all stators 200 without direct contact. The stators 200 also do not directly contact each other. In this way, the assembled stators 200 orient their approximately circular cross sections to the cross sections of the other stators 200 such that the planes defined by the cross sections of each stator 200 are approximately parallel and the distances between adjacent planes are approximately equal.

[0048] FIG. 3B further illustrates a preferred positional relationship between the stator cores 100 in the different stators 200. As previously discussed, this preferred embodiment is illustrative for generating three-phase electricity, with each stator 200 having six stator cores 100. Also, as previously discussed, each stator core 100 is designated with an "A," "B," or "C" to represent the electrical phase that the stator core 100 is intended to generate. It is further noted that the stator cores 100 in the same stator 200 are electrically connected as described in FIG. 2 above. However, such electrical connections have been omitted from FIG. 3B for the sake of brevity.

[0049] As shown in FIG. 3B, starting from phase "A", the electrical phases assigned to the stator cores 100 of the same stator 200 follow the sequence shown previously: starting from any stator core 100 designated "A" and proceeding clockwise on the same stator 200, the sequence is always A, C, B, A, C, B in this preferred embodiment.

[0050] FIG. 3B provides an imaginary triangular marker conceptually attached to one of the stator cores 100 assigned with an "A" phase to distinguish it from its "A" phase counterpart in the same stator 200. For further reference, the five stators 200 in FIG. 3B are referred to from left to right as Stator No. 1, Stator No. 2, Stator No. 3, and Stator No. 4. For further reference, the 12 o'clock position of any stator 200 is referred to as the 0 degree position, and clockwise rotation therefrom increases in angle.

[0051] 3B, the Stator No. 1 marker indicates the 0 degree position where one of the "A" phase stator cores 100 is located. Starting from the marker and proceeding clockwise, the assigned electrical phase order is A, C, B, A, C, B.

[0052] Next is Stator No. 2 and the marker indicates the 45 degree position where one of the "A" phase stator cores 100 is located. Starting at the marker and proceeding clockwise, the assigned electrical phase order is A, C, B, A, C, B.

[0053] Next is Stator No. 3 and the marker indicates the 90 degree position where one of the "A" phase stator cores 100 is located. Starting at the marker and proceeding clockwise, the assigned electrical phase order is A, C, B, A, C, B.

[0054] Next is Stator No. 4 and the marker indicates the 135 degree position where one of the "A" phase stator cores 100 is located. Starting at the marker and proceeding clockwise, the assigned electrical phase order is A, C, B, A, C, B.

[0055] Next is Stator No. 5 and the marker indicates the 180 degree position where one of the "A" phase stator cores 100 is located. Starting at the marker and proceeding clockwise, the assigned electrical phase order is A, C, B, A, C, B.

[0056] Referring to the markers, the angular displacement according to FIG. 3B increments of 45 degrees from one of the stators 200 to the next (ie, θ=45 degrees).

[0057] The above configurations according to Figures 3A and 3B aim to provide a stator core 100 for generating three-phase electricity in such a way that the stator cores 100 for generating the same electric phase are magnetized at the same instance, while the stator cores 100 for generating different electric phases are magnetized at different instances. This aim is achieved while avoiding potential differences between the same electric phases between different stators 200, thereby avoiding undesired discharges. These configurations also have further importance as described below. Similarly, the instances of magnetization are described below.

[0058] Figure 3C illustrates the electrical connections between the stator cores 100 of different stators 200 according to a preferred embodiment. Please note that in the following description of Figure 3C, references to markers; "A", "B" and "C" phases; Stators No. 1-No. 5; degree positions; etc. have the same meaning as previously described in the description of Figure 3B.

[0059] In particular, Figure 3C shows a preferred embodiment in which the stator 200 (and its stator core 100) are connected in series. The choice of such a connection is pertinent to the preferred embodiment, but is by no means essential to implementing the technical concept of the present invention. An example of a parallel connection is described below as an alternative embodiment.

[0060] More particularly, FIG. 3C illustrates the series connections between stators 200 only for stator core 100 assigned electrical phase "A."

[0061] According to FIG. 3C, Stator No. 1 has two "A" phase stator cores 100 at 0 degree and 180 degree positions, Stator No. 2 has two "A" phase stator cores 100 at 45 degree and 225 degree positions, Stator No. 3 has two "A" phase stator cores 100 at 90 degree and 270 degree positions, Stator No. 4 has two "A" phase stator cores 100 at 135 degree and 315 degree positions, and Stator No. 5 has two "A" phase stator cores 100 at 180 degree and 0 degree positions.

[0062] FIG. 3C further illustrates a preferred series connection sequence: Starting with Stator No. 1: 0 degree position and 180 degree position; Continued with Stator No. 2: 225 degree position, and 45 degree position; Continued for Stator No. 3: 90 degree position and 270 degree position; Stator No. 4 continues: 315° position and 135° position; and Continued for Stator No. 5: 180 degree position, and 0 degree position.

[0063] This preferred pattern increments 180 degrees starting from one position to the next on the same stator 200, and increments 45 degrees continuing from one position on one stator 200 to the next on the next stator 200. One skilled in the art would be able to apply the above teachings to achieve a direct connection for the "B" and "C" phases of this preferred embodiment, or to achieve a series connection in other embodiments, such as when there are more than five stators 200.

[0064] In either case, Figure 3D illustrates the series connection of three electrical phases intended to be produced by the preferred embodiment. A detailed description of Figure 3D is omitted for brevity, as it follows the pattern described in Figure 3C.

[0065] 4 shows a rotor 300 according to an aspect of a preferred embodiment, where the rotor 300 has the profile of a disk and includes a magnet receptacle 302 made of a rigid material, preferably synthetic fiber, more preferably aramid fiber, and even more preferably para-aramid fiber. Alternatively, such a rigid material may be a fiber reinforced plastic, with the reinforcing fiber being preferably synthetic fiber including nylon 6 and aramid fiber.

[0066] The magnet receptacle 302 of FIG. 4 includes a central rotor bore 304 and eight magnet slots 306 defined by cylindrical openings through the magnet receptacle 302. Each of the magnet slots 306 includes a means for retaining a magnet 308. In a preferred embodiment, such means is achieved by providing a pair of resilient members 310, preferably elongated non-metallic strips / fins, attached to the inner surface of each magnet slot 306 adjacent generally opposed edges 312 located at different ends of the magnet slot 306, from which the resilient members 310 project generally away from the edges 312 and are configured to partially cover the magnet slot 306, thereby allowing the magnet 308 to be intentionally inserted or removed through a side opening 314 provided by the partial coverage, while at the same time preventing unintentional removal of the magnet 308 that may be caused by movement of the rotor 300 during the intended operation of the preferred embodiment (described below).

[0067] FIG. 4 further illustrates that the magnets 308 are preferably held close to the edges of the magnet receptacle 302 and at a substantially uniform distance away from adjacent magnets 308 .

[0068] In a preferred embodiment, the eight magnets 308 are configured such that polarity alternates between adjacent magnets 308 (i.e., North, South, North, South, North, South, North, and South) (in FIG. 4, the North pole is represented by a "+" and the South pole is represented by a "-").

[0069] 4, the magnet receptacle 302 has dimensions of approximately 192 mm in diameter, approximately 75.75 mm from the rotor's central hole 304 to the center of the magnet slot 306, and approximately 11 mm in thickness, where the rotor's central hole 304 is an opening configured to engage and accommodate an object having an approximately hexagonal prism shape to provide a means for engaging with the cross-sectional shape of a shaft 404 (not shown in FIG. 4, described below). In this preferred embodiment, each side of the rotor's central hole 304 has a length approximately corresponding to the diameter of the magnet slot 306.

[0070] The magnet 308 may be a permanent magnet or an electromagnet. In a preferred embodiment, the magnet 308 is a generally cylindrical neodymium magnet. The magnet slot 306 is therefore configured to fully accommodate a magnet 306 of such dimensions and to accommodate the aforementioned means for holding the magnet 308. In this preferred embodiment, the magnet 308 is 30 mm in diameter and 10 mm thick.

[0071] FIG. 5A shows further aspects according to the preferred embodiment, in which five stators 200 and six rotors 300 are assembled to a shaft 404 and auxiliary rods 406. Each of the stators 200 is viewed from the side without direct contact from either side by the two rotors 300, forming a row of generally coaxially aligned members, alternating between one stator 200 and one rotor 300, with the first and last members of such row being rotors 300. Each stator 200 and its adjacent rotor 300 are sufficiently spaced apart so that magnetic induction is exerted across such members during the intended operation of this preferred embodiment (as described in more detail below). The auxiliary rods 406 pass through peripheral holes 208 of the stators 200 and are in direct contact with the stators 200, and are more preferably fixed in place by screws (not shown). However, the auxiliary rods 406 do not directly contact the rotors 300. This is made possible by the stator 200 having a larger diameter than the rotor 300, and the peripheral holes 208 being located further from the common axis than the edges of the rotor 300. Meanwhile, the shaft 404 protrudes along the common axis through the stator central hole 204 and the rotor central hole 304, but the shaft 404 is in direct contact only with the rotor central hole 304. This is made possible by the stator central hole 204 having a larger diameter than the rotor central hole 304.

[0072] In the preferred embodiment, the distance between nearest rotors 300 is substantially uniform and is about 14 mm.

[0073] Also, the stator 200 of Fig. 5A is preferably aligned and configured according to Fig. 3A, Fig. 3B, Fig. 3C and Fig. 3D above. On the other hand, the rotors 300 of Fig. 5A are preferably arranged such that the north pole (+) of the magnet 308 on one rotor 300 faces the south pole (-) of another magnet 308 of the next rotor 300 along and throughout the same axial alignment. In other words, in contrast to the configurations of the stator 200 and the stator core 100 according to Fig. 3B, Fig. 3C and Fig. 3D above, the magnets 308 of the different rotors 300 do not follow any angular displacement of Fig. 5A. The magnets 308 of all rotors 300 have their polarities (+, -) facing in the same direction when they are in the same angular position.

[0074] Here, the shaft 404 has a generally hexagonal cross-sectional area to engage with the rotor's central hole 304 when assembled according to Fig. 5A, while the stator's central hole 204 is generally circular and substantially wider than the shaft 404 to provide clearance to avoid direct contact or engagement with the shaft 404 when assembled according to Fig. 5A. In this way, when the shaft 404 rotates under mechanical power (described in more detail below), the shaft 404 only rotates the engaged rotor 300 and leaves the unengaged stator 200 stationary.

[0075] FIG. 5B shows further aspects related to the preferred embodiment. In FIG. 5B, only one rotor 300 and one stator 200 from the assembly according to FIG. 5A are shown, omitting other components for the sake of brevity. In this figure, the stator 200 is stator No. 1 according to FIG. 3B, FIG. 3C and FIG. 3D above. FIG. 5B focuses on the dimensions and arrangement of this preferred embodiment of the stator core 100 in the stator 200 and the magnets 308 in the rotor 300. In particular, FIG. 5B shows a side-by-side comparison of the front views of the rotor 300 (left side of FIG. 5B) and the stator 200 (right side of FIG. 5B), which, assuming that they are assembled with the shaft 404, auxiliary rod 406, etc., as shown in FIG. 5A above, the centers of the stator 200 and the rotor 300 are aligned at the same level.

[0076] According to FIG. 5B, the diameter (D RM ) is the inner diameter (D SC,I ) is approximately equal to 30 mm (i.e., D RM =D SC,I =30mm).

[0077] According to Fig. 5B, the stator 200 has a first imaginary circle with a circumference where the centers of all six stator cores 100 are located, and the rotor 300 has a second imaginary circle with a circumference where the centers of all eight magnets 308 are located. According to this preferred embodiment, the first and second imaginary circles have approximately the same circumference, about 480 mm. In the assembled state of Fig. 5A envisaged in Fig. 5B, the stator 200 and the rotor 300 share a common center. Thus, when projected onto a common plane (e.g., when projecting the first imaginary circle from the stator 200 onto the rotor 300, or vice versa), the two circumferences substantially overlap each other.

[0078] FIG. 5C shows further aspects related to the preferred embodiment. In FIG. 5C, only one rotor 300 and four stators 200 from the assembly according to FIG. 5A are shown, omitting other components for simplicity. In this figure, the four stators 200 are stators No. 1, No. 2, No. 3, and No. 4 according to FIG. 3B, FIG. 3C, and FIG. 3D above. FIG. 5C focuses on the angular relationship of this preferred embodiment of the stator core 100 in the stator 200 and the magnets 308 in the rotor 300. In particular, FIG. 5C shows a side-by-side comparison of the front view of the rotor 300 (left side of FIG. 5C) with stators No. 1, No. 2, No. 3, and No. 4 (starting with the one adjacent to the rotor 300 towards the right side of FIG. 5C), which assume that they are assembled with the shaft 404, auxiliary rod 406, etc. as shown in FIG. 5A above, with the centers of the stators 100 and the rotor 300 aligned at the same level.

[0079] In Figure 5C, if the eight magnets 308 are evenly distributed around an imaginary circle, the arc from the center of one magnet 308 to the center of the next magnet 308 forms an angle of approximately 45 degrees within the imaginary circle, which corresponds to the increment of angular displacement from one stator 200 to the next, as discussed above in connection with Figures 3B, 3C, and 3D. Thus, FIG. 5C shows that the magnets 308 at the 0 degree and 180 degree positions of the rotor 300 are aligned with the "A" phase stator core 100 of Stator No. 1, the magnets 308 at the 45 degree and 225 degree positions of the rotor 300 are aligned with the "A" phase stator core 100 of Stator No. 2, the magnets 308 at the 90 degree and 270 degree positions of the rotor 300 are aligned with the "A" phase stator core 100 of Stator No. 3, and the magnets 308 at the 135 degree and 315 degree positions of the rotor 300 are aligned with the "A" phase stator core 100 of Stator No. 4.

[0080] FIG. 5C serves as a simple example of angular alignment when a preferred embodiment is at rest, and also serves as a simple example of angular alignment at a given instance when such a preferred embodiment is operating as intended.

[0081] FIG. 6 shows yet another aspect according to the preferred embodiment. In these aspects, a row of five stators 200 and six rotors 300 is assembled with a shaft 404 according to FIG. 5A, FIG. 5B and FIG. 5C, and further assembled with an outer case 400 including a frame 402 for covering the stators 200, the rotors 300, the main part of the shaft 404 and the auxiliary rods 406. In this preferred embodiment, the length of the frame 402 is shorter than the length of the shaft 404, and side openings 408 are provided through the opposite sides of the frame 402 to allow the shaft 404 to pass through the confine of the frame 402. Thereby, the diameter of the side openings 408 should provide sufficient clearance for the shaft 404 to pass and rotate during the intended operation. The aforementioned components are preferably assembled such that the axis along the length of the shaft 404 is substantially horizontal to the ground, and the stators 200 and rotors 300 are not in direct contact with the frame 402, the ground and each other. The frame 402 is preferably a box made of a solid material, preferably a non-conductive and non-magnetizable material, and need not be made to encase substantially the entire stator 200 and rotor 300. As shown in Figure 6, the frame 402 is designed to loosely encase such components without affecting the intended operation of the present technical disclosure. Preferably, the outer case 400 should provide a means for supporting the shaft 404 and a means for supporting the auxiliary rod 406.

[0082] In this preferred embodiment, the means for supporting the shaft 404 is accomplished by providing a pair of pillow block bearings 410. In FIG. 6, the pillow block bearings 410 are attached and fastened to a frame extension 412 that projects generally away from a side of the frame 402 having side openings 408. Each pillow block bearing 410 may be fastened to each frame extension 412 by conventional fastening means. The pillow block bearings 410 and frame extension 412 are preferably located sufficiently close to the side openings 408 so that the shaft 404 passing through both side openings 408 may be inserted and supported through the pillow block bearings 410. In addition to structural support, the pillow block bearings 410 are intended to facilitate rotation of the shaft 404 during the intended normal operation of this preferred embodiment.

[0083] In this preferred embodiment, the above-mentioned means for supporting the auxiliary rod 406 is achieved by attaching the auxiliary rod 406 to the frame 402, specifically by screwing each end of the auxiliary rod 406 into each side of the frame 402.

[0084] After connecting each independent phase of the stator 200 in series in the outer case 400, two output wires (not shown) are used for each electrical phase. Such output wires (not shown) are connected to an overload fuse (not shown) with a thickness of 0.1 mm, and from there to any electrical consumer. FIG. 6 also shows that the shaft 404 is further coupled near one end to a means for providing mechanical power 500. According to an example according to this preferred embodiment, such a means is a 4.8 horsepower gasoline engine 502. The gasoline engine 502 is coupled to a power transmission mechanism 504 consisting of a pulley 506 with a belt 508 engaged thereto. In this preferred embodiment, there are two pulleys 506 with a size ratio of substantially 1:1, and the belt 508 is a rubber V-shaped toothed belt. One of the pulleys 506 is coupled to the gasoline engine 502, and the other pulley 506 is coupled to the shaft 404. Thus, each pulley 506 should be configured to provide sufficient fit and engagement to drive the shaft 404, as the case may be, driven by the gasoline engine 502.

[0085] The description of the intended operation begins with the means 500 for providing mechanical power. In a preferred embodiment, a gasoline engine 502 starts and provides mechanical power that is transmitted through a power transmission mechanism 504. Specifically, such mechanical power drives the rotation of a first pulley 506, which in turn pulls on a mounting belt 508, inducing a pulling action that drives the rotation of a second pulley 506 engageably coupled to the shaft 404. As a result, the shaft 404 rotates with the support and encouragement of pillow block bearings 410 located on either side of the frame 402 of the outer case 400. The now rotating shaft 404 further engages six rotors 300 and not five stators 200, so that only the rotors 300 rotate. , supplement It remains stationary with the help of the auxiliary rod 406. The stator 200 rotates simultaneously and relatively to the stator 200. do.

[0086] During rotation of the rotor 300, the magnets 308 held by the magnet slots 306 provide a magnetic field for magnetizing the stator cores 100 held on each stator 200. As the rotor 300 rotates, such magnetization alternates continuously as the rotor 300 continues to move - i.e., the stator cores 100 are magnetized by a magnetic field in a first direction and then magnetized by a magnetic field in a second, opposite direction. Although the preferred embodiment operates effectively at rotational speeds of 4,500-5,000 RPM with a load and a 1:1 relationship, this example RPM range is in no way indicative of the operating limits of an embodiment of the inventive technical concept. Such alternating magnetization may be achieved by any suitable method, including, but not limited to, a method for manufacturing a stator core. exchange Inducing the generation of electricity. In a preferred embodiment having three pairs of stator cores 100 per stator 200, the electricity generated is three phase.

[0087] Although the reasons why the above embodiment can improve power generation efficiency are not fully known to the applicant, it is believed that forming the stator core 100 by providing such wire intersections 108 leads the electromagnetic braking vectors to oppose each other and cancel each other out, thereby substantially reducing the retarding effect that typically occurs in existing power generation systems. In this respect, the embodiment according to the present disclosure effectively leads the electromagnetic braking in a non-retarding direction, rather than suppressing the electromagnetic braking (which occurs naturally according to Lenz's law).

[0088] Alternative embodiments. The following alternative embodiments are intended to be further examples to clarify the breadth of the technical concept of the present invention and to suggest further adjustments included in the technical concept of the present invention, and therefore should not be construed as limiting.

[0089] Form wire intersections in the stator core. In addition to the example of forming the wire intersections 108 according to FIG. 1B described above, the wire intersections 108 can also be formed according to an alternative configuration shown in FIG. 7. In this alternative embodiment, the stator core wires 102 are not woven in the same layer. Instead, the stator core wires 102 are wound in a predetermined winding direction 112 such that the wire intersections 108 are formed by multiple adjacent layers 110A. This alternative illustrates that the construction of the stator core 100 according to the concepts of the present disclosure relies on the effective intersection of the stator core wires 102 in the same spool 106, rather than in the same layer. In other words, the stator core wires 102 need to cross, but they do not need to weave or directly contact.

[0090] Also, while the preferred embodiment discussed above selects to form the wire intersections 108 by winding one stator core wire 102 around the core (i.e., the air core 104), such wire intersections 108 may also be formed by winding two or more stator core wires 102 around the core. In such an alternative embodiment (not shown), two or more stator core wires 102 may be joined at one or more locations to facilitate winding. Examples of such means for joining the stator core wires 102 include tying the ends (or locations near the ends) of the stator core wires 102 together and fastening the ends (or locations near the ends) of the stator core wires 102 to the core (i.e., in embodiments where the core is not the air core 104).

[0091] Parallel connection between stators. In addition to the example of series connection between the stator cores 100 of different stators 200 according to the above-mentioned Figures 3C and 3D, the electrical connection may optionally be a parallel connection. Figure 8A shows yet another alternative embodiment in which five stators 200 are connected in parallel. As with Figure 3C above, Figure 8A shows the parallel connection between the stators 200 only for the stator cores 100 assigned to electrical phase "A".

[0092] 8A provides an imaginary triangular marker conceptually attached to the stator core 100 assigned an "A" phase to distinguish it from its "A" phase counterpart on the same stator 200. For further reference, the five stators 200 in FIG. 8A are referred to from left to right as Stator No. 1, Stator No. 2, Stator No. 3, and Stator No. 4. For further reference, the 12 o'clock position of any stator 200 is referred to as the 0 degree position, and clockwise rotation therefrom increases in angle.

[0093] 8A, Stator No. 1 has two "A" phase stator cores 100 at 0 degree and 180 degree positions, Stator No. 2 has two "A" phase stator cores 100 at 45 degree and 225 degree positions, Stator No. 3 has two "A" phase stator cores 100 at 90 degree and 270 degree positions, Stator No. 4 has two "A" phase stator cores 100 at 135 degree and 315 degree positions, and Stator No. 5 has two "A" phase stator cores 100 at 180 degree and 0 degree positions. FIG. 8A further illustrates a preferred parallel connection sequence: Stator No. 1: 0 degree position is connected to the first node 212, 180 degree position is connected to the second node 214, and 0 degree position is connected to the 180 degree position. Stator No. 2: 225 degree position is connected to the first node 212, 45 degree position is connected to the second node 214, 225 degree position is connected to the 45 degree position. Stator No. 3: 90 degree position is connected to the first node 212, 270 degree position is connected to the second node 214, and 90 degree position is connected to the 270 degree position. Stator No. 4: The 315 degree position is connected to the first node 212, the 135 degree position is connected to the second node 214, and the 315 degree position is connected to the 135 degree position. Stator No. 5: 180 degree position is connected to the first node 212, 0 degree position is connected to the second node 214, 180 degree position is connected to the 0 degree position.

[0094] Here, the stator cores 100 of the same electrical phase in the same stator 200 are directly connected. Meanwhile, there is no direct connection between the stator cores 100 of different stators 200, but the stator cores 100 of different stators 200 are indirectly connected via the first node 212 and the second node 214. In particular, from a position on one stator 200 connected to the first node 212, a position on the next stator 200 that is increased by 225 degrees is also connected to the first node 212. Similarly, from a position on one stator 200 connected to the second node 214, a position on the next stator 200 that is increased by 225 degrees is also connected to the second node 214. Those skilled in the art will be able to apply the above teachings to realize the parallel connection for the "B" and "C" phases in this alternative embodiment, or to realize the parallel connection in other alternative embodiments, such as when there are more than five stators 200.

[0095] In either case, Figure 8B illustrates the parallel connection of all electrical phases intended to be produced by implementing the alternative embodiment. A detailed description of Figure 8B is omitted for brevity, as it follows the pattern described in Figure 8A.
