Description

Technical Field

[0001] The present invention relates to the technical field of motor stator equipment, and particularly to a motor stator structure that can improve the winding efficiency. Background Technique

[0002] The stator is the fixed structural part of the motor, which is used to generate a rotating magnetic field to drive the rotor to rotate or to cut the magnetic induction line when the rotor rotates to generate current. The stator includes a stator core and a stator winding. The stator winding is wound around the stator core and generates a rotating magnetic field when energized. Most of the existing traditional stators are integral, resulting in a generally long and complex winding path for the stator. The path often needs to pass through multiple slots or core gaps and is prone to getting entangled with the coil, leading to low winding efficiency. Moreover, when a part of the stator is damaged, the entire stator needs to be replaced, resulting in a high maintenance cost. For this reason, we provide a motor stator structure that can improve the winding efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a motor stator structure that can improve the winding efficiency, so as to solve the problems raised in the above background technique.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a motor stator structure that can improve the winding efficiency, including an installation part for installing components; A module part installed inside the installation part for modularizing components; Among them, after the module part is placed inside the installation part, the installation part is used to install the module part. The module part is composed of multiple independent and detachable module stators, and each module stator realizes rapid assembly through the mortise and tenon structure of a connecting block and a connecting groove.

[0005] Further, the installation part includes an auxiliary component for assisting in installing the module part; and An installation component installed inside the auxiliary component for fixing the module part; Among them, the auxiliary component is used to assist the module part, and then the installation component is used to fix the module part.

[0006] Further, the module part includes a positioning component for confirming the installation position; A winding component installed inside the positioning component for winding copper wires; and A limiting component installed inside the positioning component for limiting the positioning component; Among them, a number of positioning components are provided, and a winding component and a limiting component are arranged inside each of the number of positioning components.

[0007] Further, the auxiliary component includes a housing, and a number of extrusion grooves are formed inside the housing. One end of a first spring is fixedly connected to the inner wall of each extrusion groove, and the other end of the first spring is fixedly connected to a positioning convex block. Among them, when the positioning component is installed inside the housing, the positioning component will extrude the positioning convex block, causing the first spring to be stressed.

[0008] Further, the installation component includes a bottom plate fixedly connected to the inner wall of the housing. A number of threaded holes are formed inside the bottom plate, and bolts are threadedly connected to the inner wall of the bottom plate. Among them, the bottom plate and the installation component are connected and fixed by bolts. When the extrusion groove and the positioning groove are not aligned, the positioning convex block will push the module stator, causing the module stator and the threaded holes inside the bottom plate to be misaligned.

[0009] Further, the positioning component includes a module stator. A positioning groove is formed at one end of the module stator close to the housing. A cavity copper sheet is fixedly connected inside the positioning groove. A connection groove is formed on the right side of the module stator. A connection block is fixedly connected to one end of the module stator away from the connection groove, and the connection groove is provided in a penetrating manner. Among them, a plurality of module stators are connected through the cooperation of the connection groove and the connection block. The positioning convex block impacts the cavity copper sheet to generate a sound, so as to determine whether the module stator is installed properly.

[0010] Further, the winding component includes stator teeth fixedly connected to the inner wall of the module stator. A rectangular groove is formed inside the stator teeth, and a winding is wound on the inner wall of the rectangular groove. Among them, the rectangular groove is used to limit the winding, so that it will not come off during winding.

[0011] Further, the limiting component includes a limiting groove formed inside the module stator. An activity groove is formed inside the module stator. A limiting plate is slidably connected to the inner wall of the limiting groove. When the module stator is installed, the bottom of the limiting plate is in contact with the top of the connection block. A pushing block is fixedly connected to the top left of the limiting plate. A connecting plate is fixedly connected to the bottom of the limiting plate. The bottom of the connecting plate extends into the activity groove. A second spring is fixedly connected to the left side of the connecting plate, and the other end of the second spring is fixedly connected to the inner wall of the activity groove. Among them, the connection block is limited by pushing the limiting plate into the limiting groove. When the connection block catches the limiting groove, it means that another module stator is not installed in place or there is a foreign object at the bottom.

[0012] The present invention has the following beneficial effects: (1) The present invention sets a modular stator. Specifically, first take out the modular stator, and then wind the winding around the stator teeth inside the modular stator. Since the modular stator is designed for the module, it enables winding of multiple modular stators simultaneously. And if there are quality problems during the winding process of a certain module, only this module needs to be replaced, thus not affecting the entire stator and improving the production efficiency and the flexibility of quality control.

[0013] (2) The present invention sets a connecting block. Specifically, align the connecting block on the left side of another modular stator with the connecting groove, then push the modular stator downward to complete the connection of the modular stator. Then release the pushing block, and the second spring rebounds to push the limiting plate back into the limiting groove, making it move above the connecting block. When the limiting plate cannot cover the connecting block, it indicates that the modular stator is not installed in place and needs to be readjusted to prevent the modular stator from being at different heights after installation, thus affecting the use of the motor.

[0014] (3) The present invention sets a positioning convex block. Specifically, after the winding is completed, place the modular stator above the bottom plate, and at the same time rotate the modular stator to align the positioning grooves. And the first spring rebounds to push the positioning convex block into the positioning groove, and it makes a sound when hitting the cavity copper sheet to confirm whether the modular stator is installed in place. After being installed in place, the threaded holes of the modular stator will align with the threaded holes inside the bottom plate, and then the stator teeth are fixed on the bottom plate through bolts to complete the connection.

[0015] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-7 As shown, the present invention is a motor stator structure that can improve the winding efficiency, including an installation part 1 for installing components; A module part 2 installed inside the installation part 1 for modularizing components; Among them, after the module part 2 is placed inside the installation part 1, the installation part 1 is used to install the module part 2.

[0021] The installation part 1 includes an auxiliary component 11 for assisting in installing the module part 2; and An installation component 12 installed inside the auxiliary component 11 for fixing the module part 2; Among them, the auxiliary component 11 is used to assist the module part 2, and then the installation component 12 is used to fix the module part 2.

[0022] The module part 2 includes a positioning component 21 for confirming the installation position; A winding component 22 installed inside the positioning component 21 for winding copper wires; and The limiting component 23 is installed inside the positioning component 21, and the limiting component 23 is used to limit the positioning component 21. Among them, several positioning components 21 are provided, and a winding component 22 and a limiting component 23 are arranged inside each of the several positioning components 21.

[0023] The auxiliary component 11 includes a housing 111. A plurality of extrusion grooves 112 are formed inside the housing 111. A first spring 113 is fixedly connected to the inner wall of each extrusion groove 112, and a positioning protrusion 114 is fixedly connected to the other end of the first spring 113. Among them, when the positioning component 21 is installed inside the housing 111, the positioning component 21 squeezes the positioning protrusion 114, causing the first spring 113 to be stressed. After the winding 222 is wound, the module stator 211 is placed above the bottom plate 121, and at the same time, the module stator 211 is rotated so that the positioning grooves 212 are aligned. And the first spring 113 rebounds to push the positioning protrusion 114 into the positioning groove 212 and makes a sound when hitting the cavity copper sheet 213, so as to confirm whether the module stator 211 is installed in place. After being installed in place, the threaded holes of the module stator 211 will be aligned with the threaded holes inside the bottom plate 121, and then the stator teeth 221 are fixed to the bottom plate 121 through bolts 122 to complete the connection.

[0024] The installation component 12 includes a bottom plate 121 fixedly connected to the inner wall of the housing 111. A plurality of threaded holes are formed inside the bottom plate 121, and bolts 122 are threadedly connected to the inner wall of the bottom plate 121. Among them, the bottom plate 121 and the installation component 12 are connected and fixed through bolts 122.

[0025] The positioning component 21 includes a module stator 211. A positioning groove 212 is formed at one end of the module stator 211 close to the housing 111. A cavity copper sheet 213 is fixedly connected inside the positioning groove 212. A connection groove 214 is formed on the right side of the module stator 211, and a connection block 215 is fixedly connected to one end of the module stator 211 far from the connection groove 214. Among them, the connection grooves 214 and the connection blocks 215 are used to connect multiple module stators 211. First, the module stator 211 is taken out, and then the winding 222 is wound around the stator teeth 221 inside the module stator 211. Since the module stator 211 is set for the module, multiple module stators 211 can be wound simultaneously. And if there is a quality problem during the winding process of a certain module, only this module needs to be replaced, thus not affecting the entire stator and improving the production efficiency and the flexibility of quality control.

[0026] The winding assembly 22 includes stator teeth 221 fixedly connected to the inner wall of the module stator 211. A rectangular groove 223 is formed inside the stator teeth 221, and a winding 222 is wound around the inner wall of the rectangular groove 223; Among them, the winding 222 is limited by the rectangular groove 223 to prevent it from coming off during winding.

[0027] The limiting assembly 23 includes a limiting groove 236 formed inside the module stator 211. An activity groove 233 is formed inside the module stator 211. A limiting plate 231 is slidably connected to the inner wall of the limiting groove 236. A pushing block 232 is fixedly connected to the top left of the limiting plate 231. A connecting plate 235 is fixedly connected to the bottom of the limiting plate 231. The bottom of the connecting plate 235 extends into the activity groove 233. A second spring 234 is fixedly connected to the left side of the connecting plate 235, and the other end of the second spring 234 is fixedly connected to the inner wall of the activity groove 233; Among them, the connecting block 215 is limited by pushing the limiting plate 231 into the limiting groove 236. When the connecting block 215 catches the limiting groove 236, it means that another module stator 211 is not installed in place or there is a foreign object at the bottom. The connecting block 215 on the left side of the other module stator 211 is aligned with the connecting groove 214, and then the module stator 211 is pushed downward to complete the connection of the module stator 211. Then, the pushing block 232 is released, and the second spring 234 rebounds to push the limiting plate 231 back into the limiting groove 236, moving it above the connecting block 215. When the limiting plate 231 cannot cover the connecting block 215, it means that the module stator 211 is not installed in place and needs to be readjusted to prevent the module stator 211 from being at different heights after installation, thus affecting the use of the motor.

[0028] In use, first take out the separate module stator 211, and then wind the winding 222 around the stator teeth 221 inside the module stator 211. Since the module stator 211 is provided for the module, it enables winding of multiple module stators 211 simultaneously. And if there are quality problems during the winding process of a certain module, only this module needs to be replaced, thus not affecting the entire stator, improving production efficiency and the flexibility of quality control. When winding the winding 222, the winding 222 will enter the rectangular groove 223, and the rectangular groove 223 is used to limit the winding 222 to prevent the winding 222 from detaching from the stator teeth 221, causing the windings 222 to be wound together and resulting in scrapping. After the winding 222 is wound, place the module stator 211 above the bottom plate 121. At the same time, rotate the module stator 211 so that the positioning grooves 212 are aligned, and the first spring 113 rebounds to push the positioning protrusion 114 into the positioning groove 212 and make a sound when hitting the cavity copper sheet 213, thereby confirming whether the module stator 211 is installed in place. After being installed in place, the threaded holes of the module stator 211 will be aligned with the threaded holes inside the bottom plate 121, and then the stator teeth 221 are fixed on the bottom plate 121 through bolts 122 to complete the connection. When the extrusion groove 112 and the positioning groove 212 are not aligned, the positioning protrusion 114 will push the module stator 211, causing the threaded holes inside the module stator 211 and the bottom plate 121 to be misaligned. After the first module stator 211 is installed, push the pushing block 232 to the left, and drive the connecting plate 235 to squeeze the second spring 234 through the movement of the pushing block 232 and open the limiting groove 236. Then align the connecting block 215 on the left side of another module stator 211 with the connecting groove 214, and then push the module stator 211 downward to complete the connection of the module stator 211. Then release the pushing block 232, and the second spring 234 rebounds to push the limiting plate 231 back into the limiting groove 236 and move it above the connecting block 215. When the limiting plate 231 cannot cover the connecting block 215, it means that the module stator 211 is not installed in place and needs to be readjusted to prevent the module stator 211 from being at different heights after installation, thus affecting the use of the motor.
