Description

Technical Field

[0001] This utility model relates to stator cores, specifically a modular stator structure. Background Technology

[0002] In existing technologies, stator cores are assembled from several silicon steel sheets, which are stamped as a single piece. However, this method results in low utilization of silicon steel materials, leading to significant material waste and high costs. Therefore, a modular stator structure is proposed. Utility Model Content

[0003] The purpose of this invention is to propose a modular stator structure to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular stator structure, characterized by comprising several stator core blocks assembled from yokes and stator teeth in an I-shape, forming an integral stator core; stator slots are formed between adjacent stator core blocks, the stator teeth are arranged in a T-shape, and stator slot openings communicating with the stator slots are formed between adjacent stator teeth; and a filler is also included for filling the stator slots to change the number of stator slots without changing the stator core diameter.

[0005] More preferably, the stator slot is provided with a positioning groove, the filler is provided with a positioning block adapted to the stator slot, and the filler is also provided with a slot filling part adapted to the stator slot opening for filling the stator slot opening.

[0006] Further preferably, it also includes a dovetail groove provided on the yoke and a dovetail block provided on the stator teeth that is adapted to the dovetail groove.

[0007] A further preferred embodiment includes a dovetail block disposed on the filler and adapted to the dovetail groove on the yoke.

[0008] More preferably, it also includes a T-slot disposed on one side of the yoke and a T-block disposed on the other side of the yoke that mates with the T-slot, and the adjacent stator core blocks are connected by the mate of the T-slot and the T-block.

[0009] The beneficial effects of this utility model are as follows: by using several stator core blocks to assemble an integral stator core, and the stator core blocks are assembled from yoke and stator teeth, the entire stator core is assembled in a modular manner. The modular stator core can effectively improve the utilization rate, save silicon steel materials, and reduce costs when silicon steel sheets are stamped by a press.

[0010] Meanwhile, by using several stator core blocks to assemble a whole stator core, and before assembling the whole stator core, the enameled wire is wound around the stator core blocks, and then the several wound stator core blocks are assembled to form a whole stator core. Because the wire is wound first and then assembled, the entry of the enameled wire at the stator slot opening does not need to be considered, which can reduce the size of the stator slot opening. At the same time, there is no need to reserve space for the winding needle in the stator slot, so the space of the stator slot can be fully utilized, the stator slot fill factor can be improved, and the motor efficiency can be improved.

[0011] By setting fillers, the number of stator slots on the stator core can be changed by filling the stator slots with fillers without changing the stator core diameter. Attached Figure Description

[0021] The modular stator structure of this utility model will now be further described in conjunction with the accompanying drawings.

[0022] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model 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 indicator will also change accordingly.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] See Figures 1-8 As shown, a modular stator structure is characterized by comprising several stator core blocks 1 arranged in an I-shape by assembling yokes 11 and stator teeth 12, which are assembled around each other to form an integral stator core; stator slots 2 are formed between adjacent stator core blocks 1, and the stator teeth 12 are arranged in a T-shape, with stator slot openings 21 communicating with the stator slots 2 between adjacent stator teeth 12; it also includes a filler 3 for filling the stator slots 2 to change the number of stator slots 2 without changing the diameter of the stator core;

[0025] By using several stator core blocks 1 to assemble an integral stator core, and stator core blocks 1 are assembled from yoke 11 and stator teeth 12, the entire stator core is assembled in a modular manner. The modular stator core can effectively improve the utilization rate, save silicon steel materials, and reduce costs when silicon steel sheets are stamped by a press.

[0026] Meanwhile, by using several stator core blocks 1 to assemble an integral stator core, before assembling the integral stator core, the enameled wire is first wound onto the stator core block 1, and then several wound stator core blocks 1 are assembled to form an integral stator core. Since the wire is wound first and then assembled, the entry of the enameled wire at the stator slot 21 does not need to be considered, thereby reducing the size of the stator slot 21. At the same time, there is no need to reserve space for the winding needle in the stator slot 2, so that the space of the stator slot 2 can be fully utilized, the stator slot 2 fill factor can be increased, and the motor efficiency can be improved.

[0027] By setting the filler 3, the number of stator slots 2 on the stator core can be changed by filling the stator slots 2 with the filler 3 without changing the stator core diameter.

[0028] In one embodiment, the stator slot 2 is provided with a positioning slot 22, the filler 3 is provided with a positioning block 31 adapted to the stator slot 2, and the filler 3 is also provided with a slot filling part 32 adapted to the stator slot opening 21 for filling the stator slot opening 21.

[0029] After the stator slot 2 is filled with filler 3, the stator slot 21 is filled with filler 32 on filler 3. After filler 3 is filled in stator slot 2, adjacent stator core blocks 1 are connected by filler 3 to form a new stator core block 1.

[0030] In one embodiment, it further includes a dovetail groove 13 disposed on the yoke 11 and a dovetail block 14 disposed on the stator tooth 12 and adapted to the dovetail groove 13; the dovetail groove 13 and the dovetail block 14 limit the connection position between the stator tooth 12 and the yoke 11.

[0031] In one embodiment, a dovetail block 14 is provided on the filler 3 and adapted to the dovetail groove 13 on the yoke 11. When filling the filler 3, the stator tooth 12 in the middle part can be removed and the filler 3 that fills several stator grooves 2 can be inserted into the stator grooves 2, while the dovetail block 14 on the filler 3 is connected to the yoke 11 where the stator tooth 12 has been removed.

[0032] In one embodiment, the system further includes a T-slot 4 disposed on one side of the yoke 11 and a T-block 41 disposed on the other side of the yoke 11 and engaging with the T-slot 4. The T-slot 4 and the T-block 41 engage to connect adjacent stator core blocks 1. The T-slot 4 and the T-block 41 are used to connect adjacent yokes 11 and thus connect adjacent stator core blocks 1, while also defining the connection position of adjacent connected stator core blocks 1.

[0033] When using this utility model: first, the enameled wire is wound around several stator core blocks 1, and then the several stator core blocks 1 are sequentially inserted through the cooperation of T-slots 4 and T-blocks 41 to form an integral stator core.

[0034] When it is necessary to change the number of stator slots 2, simply fill the stator slots 2 with filler 3 before winding, and then wind the wire. After the winding is completed, the stator core block 1 can be assembled.

[0035] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
