Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor manufacturing technology, specifically to a modular winding frame for motor stators. Background Technology
[0002] In the motor manufacturing process, the stator winding process is crucial, and the winding frame, as a key component, directly affects the motor's performance and production efficiency. Traditional motor stator winding frames are mostly integral structures, requiring the entire frame to be fitted onto the stator core during installation, which is difficult. Furthermore, if any part of the frame is damaged, the entire frame needs to be replaced, increasing production costs and reducing efficiency. Simultaneously, during the winding process, the enameled wire is prone to tangling and messiness, affecting winding quality and consequently impacting motor performance. In addition, the connection between the traditional winding frame and the stator core is not secure enough, potentially loosening during motor operation and affecting stability. Therefore, a modular winding frame for motor stators is proposed. Summary of the Invention
[0003] The purpose of this invention is to provide a modular winding frame for motor stators to solve the above problems.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular winding frame for a motor stator, comprising an annular frame body mounted on the stator core, characterized in that: the frame body is composed of several frame modules circumferentially spliced together, each frame module including an open winding post and end plates at both ends of the winding post; the winding post is provided with an assembly slot adapted to the teeth of the stator core, and the side wall of the assembly slot is provided with several barbs inclined towards the stator core; one side of the end plate is provided with a snap-fit protrusion, and the other side is provided with a snap-fit groove adapted to the snap-fit protrusion of the adjacent frame module.
[0005] Preferably, the outer circumferential surface of the winding post is provided with a plurality of winding grooves adapted to the enameled wire.
[0006] Preferably, the end plate includes an inner end plate and an outer end plate.
[0007] Preferably, the outer end plate is provided with a wire guide groove for the lead wire to pass through.
[0008] The beneficial effects of this utility model are as follows: By cooperating with the snap-fit protrusions and slots, several skeleton modules are circumferentially spliced to form a ring skeleton body. The modular design significantly improves the ease of installation and maintenance of the winding skeleton. When a skeleton module is damaged, only the damaged skeleton module needs to be replaced, without disassembling or replacing the entire skeleton body, effectively reducing maintenance costs. At the same time, the matching design of the snap-fit protrusions and slots ensures that the skeleton modules can be conveniently and reliably plugged in and locked, thereby ensuring the stability of the overall structure of the ring skeleton body after splicing. The barb plays a key role when the skeleton module is installed into the teeth of the stator core through the assembly slot. Its inclined structure allows the winding post to be smoothly inserted. When the motor is subjected to external force during operation, the barb can be engaged in the interlayer gaps of the stator core laminations to form effective anchoring, suppressing the tendency of the skeleton module to loosen or be accidentally pulled out relative to the stator core, ensuring the stability of the skeleton body during motor operation, and thus improving the overall operational reliability of the motor.

[0012] The modular winding frame for motor stator described in this utility model will now be further explained with reference to the accompanying drawings.
[0013] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.
[0014] See appendix Figure 1-2As shown in the figure, a modular winding frame for a motor stator in this embodiment includes an annular frame body 1 mounted on the stator core. The frame body 1 is characterized in that: the frame body 1 is composed of several frame modules 2 spliced together circumferentially; the frame module 2 includes an open winding post 21 and end plates 22 at both ends of the winding post 21; the winding post 21 is provided with an assembly slot 211 adapted to the teeth of the stator core; the side wall of the assembly slot 211 is provided with several barbs 212 inclined towards the stator core; one side of the end plate 22 is provided with a snap-fit protrusion 23, and the other side is provided with a slot 24 adapted to the snap-fit protrusion 23 of the adjacent frame module 2.
[0015] During installation, the skeleton module 2 is installed onto the teeth of the stator core through the assembly slot 211, and the skeleton module 2 is installed at both the upper and lower ends of the teeth. When the enameled wire is wound, it is wound around the winding post 21 of the skeleton module 2 symmetrically installed on the teeth of the stator core, with the two ends restricted by the end plate 22. During the process of inserting the skeleton module 2 into the teeth of the stator core, the barb 212 on the side wall of the assembly slot 211 is smoothly inserted along the inclined surface. However, when it is necessary to pull it out, the barb 212 will form resistance with the lamination of the stator core to prevent the skeleton module 2 from being pulled out. At the same time, adjacent skeleton modules 2 can be spliced together through the snap-fit protrusion 23 on one side of the end plate 22 and the snap-fit groove 24 of the adjacent skeleton module 2 to form a ring skeleton body 1.
[0016] By engaging the snap-fit protrusions 23 and the slots 24, several skeleton modules 2 are circumferentially spliced together to form a ring-shaped skeleton body 1. This modular design significantly improves the ease of installation and maintenance of the winding skeleton. When a skeleton module 2 is damaged, only the damaged module 2 needs to be replaced, without disassembling or replacing the entire skeleton body 1, effectively reducing maintenance costs. At the same time, the matching design of the snap-fit protrusions 23 and the slots 24 ensures convenient and reliable insertion and locking between the skeleton modules 2, thereby ensuring the overall structural stability of the ring-shaped skeleton body 1 after splicing. The barb 212 plays a crucial role when the skeleton module 2 is installed into the teeth of the stator core through the mounting slots 211. Its inclined structure allows the winding post 21 to be smoothly inserted. When the motor is subjected to external force during operation, the barb 212 can engage in the interlayer gaps of the stator core laminations, forming an effective anchor and suppressing the tendency of the skeleton module 2 to loosen or be accidentally pulled out relative to the stator core, ensuring the stability of the skeleton body 1 during motor operation, thereby improving the overall operational reliability of the motor.
[0017] In one embodiment, the outer peripheral surface of the winding post 21 is provided with a plurality of winding grooves 213 adapted to the enameled wire; the winding grooves 213 can guide and position the enameled wire, making the enameled wire more regular during the winding process, avoiding tangling and improving the winding quality.
[0018] In one embodiment, the end plate 22 includes an inner end plate 221 and an outer end plate 222; the inner end plate 221 and the outer end plate 222 support the winding post 21 from both ends, thereby enhancing the structural stability of the winding post 21 and ensuring that the winding post 21 will not deform during winding and motor operation.
[0019] In one embodiment, the outer end plate 222 is provided with a wire passage groove 2221 for the lead wires to pass through; the wire passage groove 2221 makes the lead wires arranged in an orderly manner, further improving the performance and safety of the motor.
[0020] In the process of using this utility model, firstly, a skeleton module 2 is installed onto the corresponding tooth of the stator core, so that the stator core tooth is inserted into the assembly slot 211 of the skeleton module 2. At this time, the barb 212 on the side wall of the assembly slot 211 is tilted towards the core, allowing the tooth to enter smoothly. After installation, the barb 212 is engaged in the interlayer gap of the stator core lamination, realizing the initial fixation and anti-loosening of the skeleton module 2 on the tooth. Then, subsequent skeleton modules 2 are installed one by one. When each subsequent skeleton module 2 is inserted into the corresponding tooth of the stator core, its engaging protrusion 23 is inserted into the slot 24 of the adjacent skeleton module 2 that has been installed. Through the double connection method of the engagement between the barb 212 and the stator core tooth, and the engagement of the engaging protrusion 23 and the slot 24, all skeleton modules 2 are spliced together in circumferential order to finally form a complete ring skeleton body 1. The skeleton body 1 needs to be installed at both the upper and lower ends of the stator core.
[0021] During winding, the enameled wire is wound in the winding groove 213 on the outer circumferential surface of the winding post 21 of the skeleton module 2. After winding is completed, the lead wire of the enameled wire is led out along the path of the specially set wire passage groove 2221 on the outer end plate 222.
[0022] When a skeleton module 2 is damaged, simply remove the damaged skeleton module 2 from the stator core and replace it with a new skeleton module 2.
[0023] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
