[0031] In the following description, if it is pointed out to refer to a specific drawing or as shown in a specific drawing, it is only used to emphasize that in the subsequent description, most of the related content mentioned appears in that specific drawing, but it does not limit that only that specific drawing can be referred to in the subsequent description.
[0032] Please refer to Figures 1 to 4 , Figure 1 It is a schematic view of the motor stator of the present invention, Figure 2 It is an exploded schematic view of the motor stator of the present invention, Figure 3 It is a partially enlarged schematic view of the body of the motor stator of the present invention, Figure 4 It is a partially sectional schematic view of the body of the motor stator of the present invention. The motor stator 100 of the present invention includes: a body 1 and a bobbin set 2. The body 1 includes: a plurality of core bodies 11, a plurality of fixing members 12, and a plurality of enameled wires 13. A fixing member 12 is provided at each of the two opposite ends of each core body 11, and each enameled wire 13 is wound around each core body 11 and the two fixing members 12 provided at the two ends of the core body 11.
[0033] In different embodiments, only one end of each core body 11 may be provided with the fixing member 12, and a member different from the fixing member 12 is provided at the other end of the core body 11, and the enameled wire 13 is wound around each core body 11, the fixing member 12 provided at one end of the core body 11, and the member provided at the other end of the core body 11.
[0034] It is worth mentioning that if a fixing member 12 with the same structure is respectively arranged at both ends of the core body 11, in this way, a large number of fixing members 12 can be produced at one time, which can greatly reduce the production cost and also greatly improve the assembly speed. On the contrary, in the embodiment where the fixing member 12 is arranged at one end of the core body 11 and a member with a structure different from that of the fixing member 12 is arranged at the other end of the core body 11, relevant assembly personnel or equipment must confirm that the fixing member 12 arranged at one end of each core body 11 is finally located on the same side of the body 1.
[0035] As Figure 3 and Figure 4 shown, each fixing member 12 has two slots 121, and one end portion 13A of both ends of the enameled wire 13 wound around the core body 11 and the two fixing members 12 is correspondingly located in the two slots 121. In practical applications, each fixing member 12 may further include four limiting grooves 122, two of the limiting grooves 122 are located on both sides of one of the slots 121, and the other two limiting grooves 122 are located on both sides of the other slot 121, and each slot 121 communicates with the limiting grooves 122 on both sides. A part of each end of each enameled wire 13 is accommodated in the two adjacent limiting grooves 122 and the slot 121, and the two limiting grooves 122 are used to limit the movement range of the enameled wire 13 relative to the fixing member 12. In a preferred embodiment, the width 123D of each limiting groove 122 may be slightly smaller than the outer diameter of each enameled wire 13 including the outer enamel 131, and when each enameled wire 13 is arranged in the limiting groove 122, it is clamped by the two side walls forming the limiting groove 122. When a part of each end of the enameled wire 13 is correspondingly arranged in the two limiting grooves 122, a part of the enameled wire 13 will be correspondingly located in the slot 121.
[0036] In one of the preferred embodiments, each fixing member 12 may further include two bearing structures 123. Each bearing structure 123 is located in the slot 121, and one end face 1231 of each bearing structure 123 may be substantially flush with one bottom surface 1221 of each limiting groove 122. When a part of each enameled wire 13 is arranged in the two limiting grooves 122, a part of the enameled wire 13 will be correspondingly arranged on the end face 1231 of the bearing structure 123.
[0037] Please refer to Figure 2 and Figures 5 to 7 , Figure 5 which is a schematic diagram of the wire frame group of the motor stator of the present invention, Figure 6 which is an exploded schematic diagram of the wire frame group of the motor stator of the present invention, Figure 7This is a partial cross-sectional schematic diagram of the insulating base of the motor stator of the present invention. The wire frame group 2 is fixedly arranged at one end of the body 1. The wire frame group 2 includes: an insulating base 21, a plurality of conductors 22, and three output structures 3. The number of the conductors 22 and the number of the output structures 3 included in the wire frame group 2 are not limited to those shown in the figure. The insulating base 21 includes four receiving grooves 211 and a plurality of through holes 212. The four receiving grooves 211 are formed by being recessed inward from one side of the insulating base 21, and each through hole 212 penetrates through the insulating base 21. Each conductor 22 includes a fixing structure 221, a connecting structure 222, and a piercing structure 223. The fixing structure 221 is fixedly arranged in one of the receiving grooves 211. One end of the connecting structure 222 is connected to the fixing structure 221, and the other end of the connecting structure 222 is connected to the piercing structure 223. The piercing structure 223 is arranged to pass through one of the through holes 212, and the end of the piercing structure 223 is exposed on the side of the insulating base 21 opposite to the side where the plurality of receiving grooves 211 are formed.
[0038] More specifically, the insulating base 21 may include five inner wall structures 213, a plurality of connecting structures 222, and an outer wall structure 215. The five inner wall structures 213 are connected to each other at intervals, and together partition four receiving grooves 211. Each connecting structure 222 connects the outer side of one of the inner wall structures 213 and the inner side of the outer wall structure 215, and each connecting structure 222 and the inner side of the outer wall structure 215 together form a through hole 212. Each piercing structure 223 of the plurality of conductors 22 correspondingly passes through one of the through holes 212, and the fixing structure 221 of each conductor 22 is correspondingly located in one of the receiving grooves 211. A part of each piercing structure 223 is surrounded by one of the connecting structures 222, and each piercing structure 223 does not contact any adjacent piercing structure 223. The fixing structure 221 of each conductor 22 and the connecting structure 222 of each conductor 22 do not contact any part of other conductors 22. Among them, the height of each inner wall structure 213 is greater than the height of each fixing structure 221. Regarding the shape and size of the insulating base 21, they are not limited to those shown in the figure of this embodiment. As long as the insulating base 21 includes the four receiving grooves 211 and a plurality of through holes 212, the shape and size of the insulating base 21 can be changed according to requirements.
[0039] Please refer to Figures 8 to 10 , Figure 8 This is a partial enlarged schematic diagram of the piercing structure of the motor stator of the present invention. Figure 9 This is a partial cross-sectional three-dimensional schematic diagram of the piercing structure, enameled wire, and insulating base of the motor stator of the present invention. Figure 10 This is a partial cross-sectional schematic diagram of the piercing structure, enameled wire, and insulating base of the motor stator of the present invention. As Figure 8As shown, in practical applications, each piercing structure 223 may include two insertion arms 2231, there is a gap P between the two insertion arms 2231, and on the side of each insertion arm 2231 of each piercing structure 223 facing the other insertion arm 2231, there is a pointed corner structure 2231A.
[0040] As Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, after relevant personnel or equipment install multiple conductors 22 on the insulating base 21, relevant personnel or equipment can set the wire rack group 2 at one end of the body 1 to complete the assembly of the motor stator 100 of the present invention. During the process of relevant personnel or equipment fixing the wire rack group 2 to the body 1, mainly the multiple piercing structures 223 exposed on the side of the insulating base 21 opposite to the side where multiple accommodation grooves 211 are formed are correspondingly inserted into the respective slots 121 of the multiple fixing members 12 of the body 1. Thus, through the mutual engagement between the multiple piercing structures 223 and the multiple slots 121, the wire rack group 2 is fixed to one end of the body 1.
[0041] As Figure 9 and Figure 10 As shown, during the process of each piercing structure 223 being inserted into one of the slots 121, the two pointed corner structures 2231A of the piercing structure 223 will scrape off a part of the outer paint 131 of the enameled wire 13 located in the slot 121, and each piercing structure 223 will come into contact with the part of the enameled wire 13 without the outer paint 131. In this way, the purpose of electrically connecting each enameled wire 13 to each conductor 22 can be achieved. That is to say, after relevant personnel or equipment insert multiple piercing structures 223 into the corresponding slots 121, there is no need to electrically connect the multiple enameled wires 13 to the multiple conductors 22 by means such as welding. In this way, the working hours required for assembly can be significantly reduced.
[0042] Continuing from the above, for the existing common motor stators with relevant wire management structures, during the process of relevant personnel or equipment winding the enameled wires around the core body, it is necessary to manually remove the outer paint of the predetermined sections at both ends of each enameled wire. Then, when relevant personnel fix the wire management structure to one end of the body including multiple core bodies, relevant personnel must manually weld the parts of each enameled wire without the outer paint to the conductors of the wire management structure. This production method that must use manual welding not only takes a lot of labor, time, and cost, but also is prone to welding errors.
[0043] On the contrary, for the motor stator 100 of the present invention, through designs such as multiple piercing structures 223, relevant personnel or equipment do not need to remove the outer paint of partial sections of each enameled wire 13 in advance. Instead, relevant personnel only need to insert each piercing structure 223 into the corresponding slot 121 to achieve the purpose of electrically connecting multiple conductors 22 and multiple enameled wires 13, and relevant personnel or equipment do not need to perform additional operations such as welding. Therefore, compared with the production method of the traditional motor stator described above, the motor stator 100 of the present invention has the advantages of saving labor, time, and cost, and basically will not have the problem that the enameled wire is connected to the wrong conductor in the traditional method.
[0044] It is worth mentioning that in practical applications, relevant personnel can change the number of conductors 22 and the piercing structures 223 they contain according to requirements, so that the two ends of multiple enameled wires 13 can be connected in series or in parallel with each other according to requirements. The number of conductors 22 shown in the figures of this embodiment and the number of piercing structures 223 contained in each conductor 22 are only one exemplary implementation mode.
[0045] As Figure 3 、 Figure 4 、 Figure 9 and Figure 10 shown, it is worth mentioning that through designs such as the bearing structure 123 located in the slot 121 and the two limiting grooves 122 located beside the slot 121, the enameled wire 13 can be effectively fixed on the path where the piercing structure 223 is inserted into the slot 121, so that the pointed angle structure 2231A of the piercing structure 223 can smoothly scrape off the outer paint 131 of the enameled wire 13 when the piercing structure 223 is inserted into the slot 121.
[0046] As Figure 10 shown, in a preferred embodiment, when the piercing structure 223 is correspondingly inserted into the slot 121, a part of each bearing structure 123 and the enameled wire 13 located in the slot 121 are correspondingly located in the gap P between the two insertion arms 2231, and the two insertion arms 2231 of each piercing structure 223 jointly hold the enameled wire 13 and the bearing structure 123 located in the slot 121. Further, in practical applications, each insertion arm 2231 of each piercing structure 223 can include a first holding portion 2231B and a second holding portion 2231C. The first holding portion 2231B is arranged closer to the end of the insertion arm 2231 than the second holding portion 2231C, and each pointed angle structure 2231A is located between the first holding portion 2231B and the second holding portion 2231C, and the pointed angle structure 2231A is arranged in the direction towards the end of the insertion arm 2231.
[0047] The horizontal distance D1 between the inner sides 2231B1 of the two first holding parts 2231B of each puncturing structure 223 is greater than the width 123D of each carrying structure 123. The horizontal distance D2 between the inner sides 2231C1 of the two second holding parts 2231C of each puncturing structure 223 is less than the outer diameter of each enameled wire 13. The horizontal distance D3 between the inner sides of the two pointed structures 2231A of each puncturing structure 223 is less than the outer diameter of each enameled wire 13, and the horizontal distance D3 between the inner sides of the two pointed structures 2231A of each puncturing structure 223 is less than the width 123D of each carrying structure 123. When each puncturing structure 223 is inserted into the slot 121, the two pointed structures 2231A and a part of the second holding part 2231C of each puncturing structure 223 will jointly hold one of the carrying structures 123, and the two second holding parts 2231C of each puncturing structure 223 will jointly hold a part of the enameled wire 13 located in the slot 121 (the part whose outer enamel has been removed by the pointed structure 2231A). Through the designs of the first holding part 2231B and the second holding part 2231C, etc., each puncturing structure 223 can be stably held on the carrying structure 123 and the enameled wire 13, thereby ensuring the connection strength between the wire frame group 2 and the body 1, and ensuring that each conductor 22 can stably contact the inner conductor 132 of the enameled wire 13 without the outer enamel.
[0048] In addition, in one preferred embodiment, the width 123D of each slot 121 can be less than the width 123D of each puncturing structure 223. During the process of inserting each puncturing structure 223 into one of the slots 121, the two insertion arms 2231 will be squeezed and move towards each other, so that the two insertion arms 2231 can better hold the carrying structure 123 and the enameled wire 13.
[0049] Similarly, in one of the preferred embodiments, the width 123D of each of the carrier structures 123 may gradually increase from one end away from the bottom 1211 of the slot 121 towards one end closer to the bottom 1211, and the minimum width of each of the carrier structures 123 is greater than the horizontal distance D3 between the inner sides of the two pointed structures 2231A of each of the puncture structures 223. Thus, the two insertion arms 2231 of the puncture structure 223 can better hold the carrier structure 123. Wherein, the horizontal distance between the inner sides of the two first holding portions 2231B may be greater than the maximum width of each of the carrier structures 123, and when the two insertion arms 2231 of the puncture structure 223 are inserted into the slot 121, the two first holding portions 2231B may not contact the carrier structure 123, but this is not limiting. In different embodiments, when the two insertion arms 2231 of the puncture structure 223 are inserted into the slot 121, the two first holding portions 2231B may also clamp the carrier structure 123.
[0050] In one of the preferred embodiments, the horizontal distance D2 between the inner sides 2231C1 of the two second holding portions 2231C of each of the puncture structures 223 and the horizontal distance D3 between the inner sides of the two pointed structures 2231A may gradually decrease from one end closer to the end of the insertion arm 2231 towards one end away from the end of the insertion arm 2231, and the maximum horizontal distance between the inner sides of the two pointed structures 2231A is slightly less than the outer diameter of the enameled wire 13 with the outer enamel 131. Through the above design, the two second holding portions 2231C of each of the puncture structures 223 can firmly hold the inner conductor 132 of the enameled wire 13 whose outer enamel 131 has been abraded through the pointed structures 2231A.
[0051] Please refer to Figures 11 to 13 , Figure 11 which is a schematic diagram of the core body, fixing member and enameled wire of the motor stator of the present invention, Figure 12 and which is an exploded schematic diagram of the core body, fixing member and insulating member of the motor stator of the present invention. Figure 13This is a partial cross-sectional schematic view of the motor stator of the present invention. In practical applications, the multiple cores 11 included in the body 1 can be detachably fixed to each other. Specifically, a first core engaging structure 111 and a second core engaging structure 112 that can engage with each other can be respectively formed on both sides of each core 11, and the first core engaging structure 111 and the second core engaging structure 112 of two adjacent cores 11 can engage with each other. In this embodiment, the first core engaging structures 111 are convex structures, and the second core engaging structures 112 are concave structures as an example, but not limited thereto, as long as the two can engage with each other. Regarding the arrangement positions and shapes of the first core engaging structures 111 and the second core engaging structures 112 of each core 11, they are not limited to those shown in the figure.
[0052] In practical applications, each core 11 can include a connecting portion 113, an inner end portion 114, and an outer end portion 115. The two ends of the connecting portion 113 are connected to the inner end portion 114 and the outer end portion 115. In the top view of the core 11, the connecting portion 113, the inner end portion 114, and the outer end portion 115 can generally present an I-shaped structure. The first core engaging structure 111 and the second core engaging structure 112 can be provided on both sides of the outer end portion 115. After the multiple cores 11 are connected to each other to form the body 1, each inner end portion 114 corresponds to the inner side of the body 1, and each outer end portion 115 corresponds to the outer side of the body 1. In practical applications, each core 11 can be composed of multiple silicon steel sheets stacked and connected to each other, or the core 11 can be integrally formed of silicon steel material.
[0053] Each fixing member 12 can include an inner end structure 124, a connecting structure 125, and an outer end structure 126. The inner end structure 124 is connected to one end of the connecting structure 125, the outer end structure 126 is connected to the other end of the connecting structure 125, and the connecting structure 125 is located between the inner end structure 124 and the outer end structure 126. After the multiple cores 11 are connected to each other to form the body 1, the multiple inner end structures 124 are correspondingly located on the inner side of the body 1, and the multiple outer end structures 126 are correspondingly located on the outer side of the body 1. Each outer end structure 126 has two of the slots 121 and four of the limiting grooves 122.
[0054] Each connecting structure 125 includes a top wall 1251 and two side walls 1252. Opposite sides of the top wall 1251 are respectively connected to the inner end structure 124 and the outer end structure 126. The two side walls 1252 are connected to the other two sides of the top wall 1251. The top wall 1251 and the two side walls 1252 of each connecting structure 125 together form a U-shaped structure, and each connecting structure 125 is sleeved on one end of the core 11. Each enameled wire 13 is wound around the outside of each connecting structure 125 and each core 11.
[0055] In one preferred embodiment, the body 1 may further include a plurality of insulating members 14. Each insulating member 14 is disposed between the enameled wire 13 and the core 11, and each insulating member 14 is located between two adjacent enameled wires 13. Specifically, each insulating member 14 may be a sheet-like structure. Before winding the enameled wire 13 around the core 11, relevant equipment or personnel may first dispose two sheet-like insulating members 14 on both sides of the core 11, and then directly wind the enameled wire 13 around the two sheet-like insulating members 14. After the enameled wire 13 is wound around the core 11 provided with two sheet-like insulating members 14, a part of the sheet-like insulating member 14 is bent towards the enameled wire 13 so that the sheet-like insulating member 14 is located on one side of the enameled wire 13. As Figure 13 shown, in the cross-sectional schematic view of the core 11 provided with the sheet-like insulating member 14 and wound with the enameled wire 13, the enameled wire 13 wound around the core 11 is generally surrounded by the sheet-like insulating member 14. As described above, through the design of the insulating member 14, the enameled wire 13 can carry a current of 200A to 400A.
[0056] In summary, through the designs of the insulating seat 21, the plurality of conductors 22, and the plurality of piercing structures 223 of the wire frame group 2 of the motor stator 100 of the present invention, the wire frame group 2 can be directly fixed to one end of the body 1 through the plurality of piercing structures 223, and no additional structures need to be designed for the wire frame group 2 and the body 1. Thus, the overall volume of the motor stator 100 can be significantly reduced.
[0057] Please refer to Figure 14, which shows an exploded schematic view of the motor of the present invention. The motor S of the present invention includes: a motor stator 100, a housing 200, and a rotor 300. The motor stator 100 is disposed within the housing 200, and the rotor 300 is inserted through a through hole 101A of the motor stator 100. The housing 200 may, for example, include a hollow body 210 and two end caps 220. The two end caps 220 are detachably and fixedly disposed at both ends of the hollow body 210, and the rotor 300 and the motor stator 100 are both disposed within the hollow body 210. The size and shape of the housing 200 are not limited to those shown in the figure. One of the end caps 220 may include three through holes 220A for providing three output structures 3 to pass through, and the three output structures 3 are used to connect to three-phase wires. The shape of the rotor 300 and the components it includes can be set corresponding to the motor stator 100 according to requirements, which will not be limited here. For a detailed description of the motor stator 100, please refer to the descriptions of the foregoing embodiments, and will not be elaborated here. As described above, the motor stator 100 of the present invention and the motor S including the motor stator 100 can be separately and independently manufactured, sold, or implemented.
