Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular provides a matrix motor. Background Technology

[0002] An electric motor consists of a stator and a rotor. The stator has stator slots, and the windings are wound around the stator slots. By passing current through the windings of the stator, the stator generates a rotating magnetic field vector. The rotating magnetic field attracts the rotor to rotate, and ultimately, the motor outputs torque.

[0003] In the field of matrix motors, the manufacturing logic is typically rotor-centric, meaning that the center of the rotating magnetic field vector formed by the windings on each stator tooth after charging coincides with the rotation center of the rotor. Consequently, such matrix motors often suffer from large size, heavy weight, and difficulty in assembly and disassembly when assembled. Utility Model Content

[0004] The purpose of this application is to provide a matrix motor that addresses the problems of large size, heavy weight, and difficult assembly / disassembly of existing matrix motors.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] In a first aspect, this application provides a matrix motor, comprising a plurality of modular motor elements, preferably wherein the rotor structures of each modular motor element are parallel in the axial direction;

[0007] The modular motor element includes a rotor structure and multiple first stator structures;

[0008] A plurality of first stator structures, each first stator structure including a first stator core and a plurality of first windings, the first stator core including at least two first stator teeth, one end of each first stator tooth forming a first stator pole shoe, and the other end of each first stator tooth being connected to the end of at least one other first stator tooth away from the first stator pole shoe to form at least one first connecting portion, each first winding being wound on the corresponding first stator tooth and located between the first connecting portion and the first stator pole shoe;

[0009] In this configuration, each of the first stator structures is arranged circumferentially around the rotation center axis of the rotor structure, and the first stator pole shoes of each of the first stator structures are oriented toward the rotor structure. Each of the first stator structures forms a first magnetic field vector at the corresponding first connection portion. The rotation directions of each of the first magnetic field vectors are the same, and the rotation directions of each of the first magnetic field vectors are opposite to the rotation directions of the corresponding rotor structure.

[0010] The beneficial effects of the embodiments of this application are as follows: The matrix motor provided by this application includes one or more modular motor elements, each of which is manufactured with a stator structure as the center. That is, after each first winding is energized, the first connection part of each first stator structure forms a first magnetic field vector, and each first magnetic field vector surrounds the rotor structure. Thus, the rotor structure rotates around the axis under the drive of each first magnetic field vector to achieve torque output. The matrix motor provided by this application has a first stator structure that can be used as a standard part. During assembly, the orientation of the first windings on the corresponding first stator structure can be adjusted sequentially according to the rotation direction of the rotor structure. This is more conducive to realizing the array layout of the first stator structure and the rotor structure, with higher space utilization and lighter overall weight. Furthermore, since the first stator structure is a uniform standard part, disassembly and replacement are more convenient.

[0011] In some embodiments, the number of the first stator teeth is an integer multiple of the number of phases of the current modular motor element, wherein the integer is greater than or equal to 2; or...

[0012] The number of the first stator teeth is the same as the number of phases of the current modular motor element.

[0013] By adopting the above technical solution, the number of first stator teeth is an integer multiple or equal to the number of phases of the current modular motor element, which can make each first stator structure around the current rotor structure form a closed magnetic field and reduce the probability of magnetic leakage.

[0014] In some embodiments, the number of first stator teeth wound in each phase winding of the modular motor element is the same.

[0015] By adopting the above technical solution, the number of first stator teeth wound in each phase winding of the current modular motor element is the same, thereby achieving magnetic field balance in each phase.

[0016] In some embodiments, in the same modular motor element, the winding sequence of each first winding of each first stator structure surrounding the same rotor structure is in the phase sequence opposite to the rotation direction of the rotor structure.

[0017] By adopting the above technical solution, based on the first stator structure being a unified standard component, the phase sequence of the first windings wound on each first stator tooth arranged circumferentially toward the rotor structure of each first stator structure should be arranged in the same phase sequence as the rotation direction of the rotor structure, so as to satisfy that the phase sequence of the windings on each first stator tooth surrounding the rotor structure is the same as the rotation direction of the rotor structure.

[0018] In some embodiments, the number of the first stator teeth is three, and each of the first stator teeth is circumferentially distributed at equal intervals around the geometric center of the first connecting portion.

[0019] By adopting the above technical solution, the included angle between each first stator tooth is 120° to meet the working requirements of a three-phase motor.

[0020] In some embodiments, the first connecting portion of the first stator structure is connected to form a second connecting portion, and a second magnetic field vector is formed on the second connecting portion. The rotation direction of the second magnetic field vector is opposite to the rotation direction of the first magnetic field vector formed at the first connecting portion.

[0021] By adopting the above technical solution, the first connecting part is connected by the second connecting part, so as to realize more topological structures of the first stator structure.

[0022] In some embodiments, the number of the first stator teeth is six, and every two first stator teeth form a group and one end of each first stator tooth is connected to form the first connecting portion. Each first connecting portion is circumferentially distributed at equal intervals with the geometric center of the second connecting portion as the center.

[0023] In some embodiments, the modular motor element includes a plurality of second stator structures, each second stator structure including a second stator core and a second winding. The second stator core includes an enclosure portion and a second stator tooth disposed on the enclosure portion. The end of the second stator tooth away from the enclosure portion forms a second stator pole shoe. Each second winding is wound on the corresponding second stator tooth and is located between the enclosure portion and the second stator pole shoe. The enclosure portion is spliced ​​to form the outer edge of the matrix motor.

[0024] By adopting the above technical solution, the second stator structure is used as a structural supplement to the modular motor element, thereby realizing more topological structures for the modular motor element.

[0025] In some embodiments, a hollow structure is formed within the matrix motor. The modular motor element includes a third stator structure, which includes a third stator core and a third winding. The third stator core includes a frame portion and a third stator tooth disposed on the frame portion. The end of the third stator tooth away from the frame portion forms a third stator pole shoe. The third winding is wound around the third stator tooth and located between the frame portion and the third stator pole shoe. The third stator pole shoe points toward the rotor structure. The frame portions enclose each other to form the hollow structure.

[0026] By adopting the above technical solution, a hollow structure can be formed inside the matrix motor, and the output shaft, mechanical transmission components, and fixed support can be installed in this hollow structure.

[0027] In some embodiments, the matrix motor includes a multi-stage transmission mechanism that is drively connected to the output shaft of each rotor structure of each modular motor element, and the axial directions of the rotor structures of each modular motor element are parallel.

[0028] By adopting the above technical solution and utilizing a multi-stage transmission mechanism, the torque output by each output shaft of the modular motor element is converged. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0053] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0054] An electric motor consists of a stator and a rotor. The stator has stator slots, and windings are wound around these slots. By passing current through the stator windings, a rotating magnetic field vector is generated. This rotating magnetic field attracts the rotor to rotate, ultimately producing torque. However, in the field of matrix motors, the manufacturing logic is typically rotor-centric. That is, the center of the rotating magnetic field vector formed by the windings on each stator tooth after charging coincides with the rotor's rotation center. This results in a relatively fixed stator structure for such matrix motors, and often leads to problems such as large size, heavy weight, and difficulty in assembly and disassembly during installation.

[0055] In view of this, this application provides a matrix motor, wherein the matrix motor includes several modular motor elements, each modular motor element including a rotor structure and multiple first stator structures. A first magnetic field vector is formed at the first connection portion of each first stator structure when each first winding is energized. Furthermore, the rotation direction of each first magnetic field vector is the same, and the rotation direction of each first magnetic field vector is opposite to the rotation direction of the corresponding rotor structure. That is, the rotor structure is driven by each first magnetic field vector to achieve rotation around its axis. Thus, the first stator structures are easier to manufacture in a standardized manner. During assembly, the orientation of the first windings on the corresponding first stator structure can be adjusted sequentially according to the rotation direction of the rotor structure. This is more conducive to the array layout of the first stator and rotor structures, resulting in higher space utilization and lighter overall weight. Moreover, the first stator structures are standardized parts, making disassembly and replacement more convenient.

[0056] Please refer to Figures 1 to 5 Firstly, the matrix motor 100 provided in the embodiments of this application includes a plurality of modular motor elements 101.

[0057] The modular motor element 101 includes a rotor structure 10 and a plurality of first stator structures 20; each first stator structure 20 includes a first stator core 21 and a plurality of first windings 22. The first stator core 21 includes at least two first stator teeth 211. One end of each first stator tooth 211 forms a first stator pole shoe 212, and the other end of each first stator tooth 211 is connected to the end of at least one other first stator tooth 211 away from the first stator pole shoe 212 to form at least one first connection portion 213. Each first winding 22 is wound on the corresponding first stator tooth 211 and is located between the first connection portion 213 and the first stator pole shoe 212.

[0058] Each first stator structure 20 is arranged circumferentially around the rotation center axis of the rotor structure 10. The first stator pole shoe 212 of each first stator structure 20 is oriented toward the rotor structure 10. Each first stator structure 20 forms a first magnetic field vector 20a at the corresponding first connection portion 213. The rotation direction of each first magnetic field vector 20a is the same, and the rotation direction of each first magnetic field vector 20a is opposite to the rotation direction of the corresponding rotor structure 10.

[0059] Understandably, the matrix motor 100 includes several modular motor elements 101. For example, the matrix motor 100 may have only one modular motor element 101, or it may include multiple modular motor elements 101. Here, each modular motor element 101 includes a rotor structure 10. Preferably, the axial directions of each rotor structure 10 are parallel, and the rotor structures 10 of each modular motor element 101 may also be located in the same horizontal plane. In this case, the axial direction of the output shaft of each rotor structure 10 should be perpendicular to the horizontal plane in which each rotor structure 10 is located.

[0060] The first stator structure 20 refers to the stator structure located in the middle region of the matrix motor 100. Compared with the stator structure in the edge region of the matrix motor 100, the first stator structure 20 has the same structural characteristics. That is, since the outer contour of the matrix motor 100 can be square, circular, or hexagonal, the structural shape of the stator structure located in the edge region of the matrix motor 100 is different.

[0061] The first stator core 21 is the main part of the first stator structure 20. It is usually formed by stacking sheet structures such as silicon steel and iron-based composite materials. The first winding 22 is the core component in the first stator structure 20 that realizes electromagnetic energy conversion. It is usually enameled copper wire or aluminum wire, or superconducting tape, etc., and is wound on the first stator core 21 by centralized winding or distributed winding. Specifically, the first stator core 21 includes at least two first stator teeth 211. The first stator teeth 211 are used for winding the first winding 22. One end of each first stator tooth 211 forms a first stator pole shoe 212 for pointing towards the rotor structure 10. Here, the function of the first stator pole shoe 212 is to guide the magnetic circuit and increase the torque density. The other end of each first stator tooth 211 is connected to the end of at least one other first stator tooth 211 away from the first stator pole shoe 212 to form a first connection part 213. For example, when the same first stator core 21 has only one first connecting portion 213, that is, the ends of the non-first stator pole shoes 212 of each first stator tooth 211 are connected, then the first connecting portion 213 is the middle part of the first stator core 21, that is, the geometric center of the first connecting portion 213 is the geometric center of the first stator core 21. As another example, the same first stator core 21 may also have multiple first connecting portions 213 simultaneously, that is, there are multiple first stator teeth 211 in the current first stator core 21, and the ends of the non-first stator pole shoes 212 of each first stator tooth 211 are connected in pairs or more, but not all of the first stator teeth 211. Since the ends of the non-first stator pole shoes 212 are connected, the first connecting portions 213 are circumferentially distributed at equal intervals about the geometric center of the current first stator core 21. Thus, when each first winding 22 is energized, a first magnetic field vector 20a is formed in the first connecting portion 213. This first magnetic field vector 20a has directionality, and its rotation direction is opposite to the rotation direction of the current rotor structure 10. For example, when the rotor structure 10 rotates clockwise, the first magnetic field vector 20a rotates counterclockwise, or vice versa. Furthermore, the rotation direction of the first magnetic field vector 20a around each first stator structure 20 of the current rotor structure 10 is the same.

[0062] For example, such as Figure 5As shown, in a modular motor element 101 composed of a rotor structure 10, there are six first stator structures 20. The first stator core 21 of the first stator structure 20 includes three first stator teeth 211. The ends of the non-first stator pole shoes 212 of each first stator tooth 211 are connected to form a first connecting portion 213. Each first stator tooth 211 is circumferentially distributed at equal intervals with the geometric center of the first connecting portion 213 as the center. That is, the included angle between each first stator tooth 211 is 120°. Each first stator structure 20 encloses a rotor structure 10. That is, the first stator pole shoe 212 of each first stator structure 20 points to the rotor structure 10. Thus, when three-phase alternating current is applied to each first winding 22 of each first stator structure 20, a first magnetic field vector 20a with a counterclockwise rotation direction is formed at the first connection part 213 of each first stator structure 20. At this time, the rotor structure 10 rotates clockwise under the tangential action of each first magnetic field vector 20a to output torque. Figure 5 The structure shown, consisting of six first stator structures 20 surrounding a rotor structure 10, is a modular motor element 101. Of course, when multiple first stator structures 20 are arranged in an array, one of the aforementioned first stator structures 20 can be combined with five other first stator structures 20 to form a rotor structure 10, and so on, to form a matrix motor 100 with multiple output terminals.

[0063] The matrix motor 100 provided in this application includes one or more modular motor elements 101, each of which is manufactured with a stator structure as the center. That is, after each first stator structure 20's first connection portion 213 is energized, a first magnetic field vector 20a is formed, and each first magnetic field vector 20a surrounds the rotor structure 10. Thus, the rotor structure 10 rotates around its axis under the drive of each first magnetic field vector 20a to achieve torque output. The matrix motor 100 provided in this application allows the first stator structure 20 to be used as a standard part. During assembly, the orientation of the first windings 22 on the corresponding first stator structure 20 can be adjusted sequentially according to the rotation direction of the rotor structure 10. This is more conducive to the array arrangement of the first stator structure 20 and the rotor structure 10, resulting in higher space utilization and lighter overall weight. Furthermore, since the first stator structure 20 is a standardized part, disassembly and replacement are more convenient.

[0064] In some embodiments, the number of first stator teeth 211 is an integer multiple of the number of phases of the current modular motor element 101, where the integer is greater than or equal to 2; or, the number of first stator teeth 211 is equal to the number of phases of the current modular motor element 101.

[0065] Understandably, the number of phases of a modular motor element 101 refers to the number of independently powered windings in the stator windings surrounding its rotor structure 10, which are typically single-phase, two-phase, three-phase, or multi-phase.

[0066] The number of first stator teeth 211 being an integer multiple of the number of phases of the current modular motor element 101 can mean that the number of first stator teeth 211 is two, three, or more times the number of phases of the current modular motor element 101. Alternatively, the number of first stator teeth 211 can also be equal to the number of phases of the current modular motor element 101.

[0067] For example, when the number of phases of the current modular motor element 101 is three, the number of first stator teeth 211 is three. Each first stator tooth 211 is circumferentially distributed at equal intervals with the geometric center of the first connecting part 213 as the center. That is, the included angle between each first stator tooth 211 is 120°.

[0068] In this way, each of the first stator structures 20 surrounding the current rotor structure 10 can form a symmetrical and closed magnetic field, thereby making the magnetic force generated between each of the first stator structures 20 and the rotor structure 10 it surrounds symmetrical.

[0069] Please refer to Figure 2 or Figure 8 In some embodiments, the number of first stator teeth 211 wound on each phase winding of the modular motor element 101 is the same.

[0070] Understandably, such as Figure 2 As shown, the current modular motor element 101 is three-phase, with one winding for each phase. Therefore, there are three first stator teeth 211, and each first stator tooth 211 is wound with one corresponding winding. Figure 8 As shown, the current modular motor element 101 is three-phase, with two windings in each phase. Therefore, the number of first stator teeth 211 is six, and the two windings of the same phase are wound on the corresponding two first stator teeth 211.

[0071] In this way, the magnetic fields of each phase of the modular motor element 101 can be kept in balance.

[0072] Please refer to Figure 5 or Figure 10 In some embodiments, in the same modular motor element 101, the winding sequence of each first winding 22 of each first stator structure 20 surrounding the same rotor structure 10 is wound in a phase sequence opposite to the rotation direction of the rotor structure 10.

[0073] Here, as Figure 5As shown, taking a three-phase modular motor element 101 as an example, there are six first stator structures 20, and each first stator structure 20 has three first stator teeth 211, with an included angle of 120° between each first stator tooth 211. Each first stator structure 20 surrounds the rotor structure 10, that is, six first stator pole shoes 212 are distributed around the rotor structure 10. As the rotor structure 10 rotates clockwise, the first stator windings 22 corresponding to the first stator pole shoes 212 facing the rotor structure 10, namely phase A, phase B, phase C, phase A, phase B, and phase C, are also arranged clockwise around the rotor structure 10. So, in the first stator structure 20 at the first position, the first stator pole shoe 212 facing the first stator tooth 211 of the current rotor structure 10 has an A-phase first winding 22 wound on it. In the current first stator structure 20, in a counter-clockwise direction opposite to the rotation direction of the rotor structure 10, the remaining two first stator teeth 211 of the first stator structure 20 are then wound with a B-phase first winding 22 and a C-phase first winding 22, respectively. This process continues. Similarly, in the second position, the first stator structure 20 at the first stator pole shoe 212 facing the first stator tooth 211 of the current rotor structure 10 has a B-phase first winding 22 wound on it. In the current first stator structure 20, in a counter-clockwise direction opposite to the rotation direction of the rotor structure 10, the remaining two first stator teeth 211 of the first stator structure 20 are then wound with a B-phase first winding 22. In the counterclockwise direction opposite to the rotation direction of the rotor structure 10, the C-phase first winding 22 and the A-phase first winding 22 are wound on the remaining two first stator teeth 211 of the first stator structure 20, respectively. The first stator pole shoe 212 of the third position of the first stator structure 20 is wound with the C-phase first winding 22 on the first stator teeth 211 of the current rotor structure 10. In the current first stator structure 20, in the counterclockwise direction opposite to the rotation direction of the rotor structure 10, the A-phase first winding 22 and the B-phase first winding 22 are wound on the remaining two first stator teeth 211 of the first stator structure 20, respectively. This continues until the first windings 22 on the sixth position of the first stator structure 20 are completed.

[0074] When the first stator structure 20 at the corresponding position needs to be repaired or replaced, one of the first stator structures 20 can be removed, and a new first stator structure 20 can be added according to the phase.

[0075] Thus, based on the fact that the first stator structure 20 is a standardized component, the first winding 22 of each first stator structure 20 needs to be wound in a phase sequence opposite to the rotation direction of the rotor structure 10, thereby satisfying that the rotation direction of the first magnetic field vector 20a at the first connection 213 is opposite to the rotation direction of the rotor structure 10. Furthermore, the phase sequence of the first winding 22 wound on the first stator teeth 211 arranged circumferentially toward the rotor structure 10 of each first stator structure 20 should be assembled in the same phase sequence as the rotor rotation direction, satisfying that the phase sequence of the windings on each first stator tooth surrounding the rotor structure is the same as the rotation direction of the rotor structure, and finally satisfying the need for disassembly and replacement of the first stator structure 20.

[0076] Please refer to Figures 2 to 4 , Figure 6 In some embodiments, the number of first stator teeth 211 is three, and each first stator tooth 211 is circumferentially distributed at equal intervals with the geometric center of the first connecting portion 213 as the center.

[0077] Here, the included angle between each of the first stator teeth 211 is 120° to meet the working requirements of the three-phase motor.

[0078] Please refer to Figure 7 and Figure 8 In some embodiments, the first connecting portion 213 of the first stator structure 20 is connected to form a second connecting portion 214, and a second magnetic field vector 20b is formed on the second connecting portion 214. The rotation direction of the second magnetic field vector 20b is opposite to the rotation direction of the first magnetic field vector 20a formed at the first connecting portion 213.

[0079] Understandably, the first stator structure 20 can also adapt to shape changes to meet the needs of various usage scenarios.

[0080] The function of the second connecting part 214 is to connect the structure of each first connecting part 213 when the number of first connecting parts 213 in the current first stator structure 20 is two or more. Therefore, the structure of the second connecting part 214 is not limited, as long as it can connect each first connecting part 213 and make each first connecting part 213 stable.

[0081] For example, such as Figure 8As shown, the first stator structure 20 has six first stator teeth 211. Each pair of first stator teeth 211 forms a group, and one end of each first stator tooth 211 is connected to form a first connecting portion 213. Therefore, the first stator structure 20 has three first connecting portions 213. Each first connecting portion 213 is circumferentially distributed at equal intervals around the geometric center of a second connecting portion 214. In this case, the second connecting portion 214 is a triangular structure, with each edge at a 120° angle to the others. The geometric center of the second connecting portion 214 is the solid midpoint of this triangular structure. Alternatively, the second connecting portion 214 can also be a hollow equilateral triangle structure, meaning each first connecting portion 213 has two edges connected to it. In this case, the geometric center of the second connecting portion 214 is the virtual midpoint of this hollow equilateral triangle structure. Of course, the second connecting portion 214 can also be a ring structure, with each first connecting portion 213 connected to the ring structure.

[0082] In addition, in order to achieve magnetic balance, the rotation direction of the second magnetic field vector 20b formed at the second connection 214 is opposite to the rotation direction of the first magnetic field vector 20a at each of the first connection 213.

[0083] Thus, the first connecting part 213 is connected by the second connecting part 214 to realize more topological structures of the first stator structure 20.

[0084] Please refer to Figure 7 In some embodiments, the number of first stator teeth 211 is six, and every two first stator teeth 211 form a group and one end of each first stator tooth 211 is connected to form a first connecting part 213. Each first connecting part 213 is circumferentially distributed at equal intervals with the geometric center of the second connecting part 214 as the center.

[0085] Here, the first stator structure 20 of this application is still used to adapt to the three-phase modular motor element 101. For example... Figure 8 As shown, phase A and phase C are wound on the two first stator teeth 211 at the first position, phase B and phase A are wound on the two first stator teeth 211 at the second position, and phase C and phase B are wound on the two first stator teeth 211 at the third position. In this way, a first magnetic field vector 20a rotating counterclockwise can be formed at each of the three first connecting parts 213, and a second magnetic field vector 20b rotating clockwise can be formed at the second connecting part 214.

[0086] Furthermore, each first stator structure 20 having the second connecting portion 214 can be combined with each first stator structure 20 without the second connecting portion 214 to form a modular motor element 101. For example... Figure 9As shown, there are three first stator structures 20 with the second connecting part 214 and three first stator structures 20 without the second connecting part 214. The two types of first stator structures 20 are arranged alternately at equal intervals with the rotation center of the rotor structure 10 as the center. Compared with the array arrangement of only the first stator structures 20 without the second connecting part 214, the arrangement of the two types of first stator structures 20 is more compact in space and has a higher space utilization rate.

[0087] Please refer to Figure 10 In some embodiments, the modular motor element 101 includes a plurality of second stator structures 30, each second stator structure 30 including a second stator core 31 and a second winding 32. The second stator core 31 includes an enclosure portion 311 and a second stator tooth 312 disposed on the enclosure portion 311. The end of the second stator tooth 312 away from the enclosure portion 311 forms a second stator pole shoe 313. Each second winding 32 is wound on the corresponding second stator tooth 312 and is located between the enclosure portion 311 and the second stator pole shoe 313. The enclosure portion 311 is spliced ​​to form the outer edge of the matrix motor 100.

[0088] Understandably, the second stator structure 30 is a stator structure disposed on the outer edge of the matrix motor 100, that is, at least a portion of the second stator structure 30 constitutes the outer edge of the matrix motor 100.

[0089] Specifically, the enclosure portion 311 in the second stator core 31 is used to splice together to form the outer edge of the matrix motor 100. Here, the second stator structure 30 may include a second stator tooth 312 and a second winding 32. In this case, one end of the second stator tooth 312 is connected to the enclosure portion 311, and the second stator pole shoe 313 on the other end of the second stator tooth 312 away from the enclosure portion 311 faces the rotor structure 10. Alternatively, the second stator structure 30 may include multiple second stator teeth 312 and multiple second windings 32. In this case, one end of each of the multiple second stator teeth 312 is connected to the enclosure portion 311, and the multiple second stator pole shoes 313 on the other end of the multiple second stator teeth 312 away from the enclosure portion 311 face the rotor structure 10.

[0090] The enclosure portions 311 of each second stator structure 30 are spliced ​​together to form the outer edge of the matrix motor 100, so that the matrix motor 100 has a closed space.

[0091] Thus, by using the second stator structure 30 as a structural supplement to the modular motor element 101 of the matrix motor 100, more topological structures of the matrix motor 100 can be realized.

[0092] Please refer to Figure 11In some embodiments, the matrix motor 100 has a hollow structure. The hollow structure is used to house structures such as the output shaft, mechanical transmission components, and fixed supports.

[0093] Here, the hollow structure can form the central region of the matrix motor 100, or it can be other regions on the non-insulated side. Similarly, the modular motor element 101 includes a third stator structure 40, which includes a third stator core 41 and a third winding (not shown in the figure). The third stator core 41 includes a frame portion 411 and a third stator tooth 412 provided on the frame portion 411. The end of the third stator tooth 412 away from the frame portion 411 forms a third stator pole shoe 413. The third winding is wound on the third stator tooth 412 and is located between the frame portion 411 and the third stator pole shoe 413. The third stator pole shoe 413 points toward the rotor structure 10.

[0094] Please refer to Figure 12 In some embodiments, the matrix motor includes a multi-stage transmission mechanism 200, which is driven to the output shaft of each rotor structure 10 of the modular motor element 101, and the axial directions of the rotor structures 10 of each modular motor element 101 are parallel.

[0095] Understandably, the multi-stage transmission mechanism 200 includes a first-stage gear structure 201 and a second-stage gear structure 202. The first-stage gear structure 201 is meshed with the output shaft of each rotor structure 10 of the modular motor element 101, and the second-stage gear structure 202 is meshed with the first-stage gear structure 201, so as to meet the convergence of the output torque of each rotor structure 10.

[0096] In this way, the multi-stage transmission mechanism 200 is used to converge the torque output by the output shaft of each modular motor element 101.

[0097] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
