Description

Technical Field

[0001] This utility model relates to the field of motor technology, and more specifically, to a motor and a refrigeration device. Background Technology

[0002] Currently, refrigeration equipment is equipped with a motor, which outputs power by rotating during operation. During this power output, the motor itself vibrates, and this vibration is transmitted to the refrigeration equipment, resulting in significant noise during operation. In related technologies, to reduce noise, a support structure is used to support the motor and block some of the motor's vibration from being transmitted to the refrigeration equipment. However, because the support structure needs high rigidity to ensure stability in supporting the motor, its vibration isolation effect is often poor, leading to relatively high noise levels during operation. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this utility model proposes an electric motor.

[0005] The second aspect of this utility model provides a refrigeration device.

[0006] In view of the above, the first aspect of the present invention provides an electric motor, including a stator assembly, mounting ears, and a vibration damper, wherein the mounting ears are disposed on the stator assembly; the vibration damper is provided with a first mounting groove, and at least part of the mounting ears are located in the first mounting groove; wherein the vibration damper is provided with a plurality of through holes, and the plurality of through holes are arranged circumferentially along the stator assembly.

[0007] In this technical solution, the motor includes a stator assembly, which, when energized, can cooperate with the rotor assembly to achieve power output.

[0008] The motor also includes mounting ears, which are located on the stator assembly. The mounting ears support the stator assembly, thereby enabling the motor to be installed and fixed.

[0009] The motor also includes a vibration damper, which has a first mounting groove. At least part of the mounting ears are located within the first mounting groove, meaning the vibration damper is fitted onto the outside of the mounting ears. This vibration damper supports the stator assembly, ensuring the motor's stability during operation. The vibration damper's fitting onto the mounting ears via the first mounting groove facilitates assembly, simplifies the assembly process, and reduces assembly difficulty. Furthermore, the first mounting groove allows the vibration damper to support and dampen the stator assembly in multiple directions, improving both the stability of the vibration damper's support for the stator assembly and its vibration damping effect.

[0010] The vibration damper has multiple through holes arranged circumferentially along the stator assembly. When vibration reaches these through holes, it loses its transmission medium, allowing the through holes to attenuate the vibration. Because the through holes attenuate vibration transmission, the vibration generated by the motor during operation is attenuated by the through holes in the vibration damper as it is transmitted to the refrigeration equipment. This improves the vibration damping effect of the damper, thereby reducing the noise of the refrigeration equipment during operation and improving its overall quality.

[0011] Specifically, when the motor is working, the vibration generated by the motor is transmitted in the form of vibration waves. When the vibration waves reach the through hole, they are transmitted to the air by the damping component. The vibration waves gradually weaken in the air, so that the vibration waves will not continue to be transmitted to the refrigeration equipment. In this way, the through hole on the damping component can attenuate the transmission of vibration.

[0012] Through holes can attenuate the axial, radial, and circumferential excitation of the stator assembly, that is, through holes can attenuate the transmission of vibration.

[0013] Optionally, there are multiple mounting ears, arranged at intervals along the circumference of the stator assembly. The vibration damping element is sleeved on the mounting ear. The vibration damping element can effectively reduce the transmission of the lateral excitation of the stator assembly to the refrigeration equipment, while also giving the vibration damping element good support capacity.

[0014] Optionally, the vibration damper can be made of an elastic material (such as rubber or elastomer), which has good vibration damping performance. Because elastic materials can absorb and attenuate vibration energy, the use of vibration dampers can effectively reduce the vibration transmission of the motor on the support, protect the motor and the support, and extend the service life of the equipment. Of course, the vibration damper can also reduce the transmission of noise, thereby improving the overall quietness of the equipment.

[0015] The hardness range of the vibration damper is HS (Shore hardness) 30 to HS70.

[0016] Optionally, the opening of the first mounting groove is located on the circumferential inner side of the vibration damper, and the mounting ear is inserted into the first mounting groove through the opening of the first mounting groove.

[0017] Optionally, the damper has a hexahedral structure, and the two sides of the damper in the circumferential direction of the stator assembly are planes.

[0018] In some technical solutions of this utility model, optionally, the multiple through holes include a first hole, which extends from the circumferential sidewall of the damper to the stator assembly, penetrates the damper, and is located on the circumferential side of the first mounting groove.

[0019] In this technical solution, the first hole extends from the circumferential sidewall of the vibration damper towards the stator assembly. The first hole penetrates the vibration damper, thus reducing the transmission of motor vibration to the refrigeration equipment and providing the vibration damper with sufficient strength. This reduces noise while improving the stability of the vibration damper's support for the motor. The first hole's extension from the circumferential sidewall of the vibration damper towards the stator assembly effectively attenuates vibration transmission along the circumferential direction of the stator assembly, thereby weakening circumferential excitation and reducing noise during motor and refrigeration equipment operation. Located on the circumferential side of the first mounting groove, the first hole not only attenuates vibration transmission along the circumferential direction of the stator assembly but also attenuates vibration transmission along the radial direction of the stator assembly, further reducing noise during motor and refrigeration equipment operation. Furthermore, the first hole also attenuates vibration transmission along the axial direction of the stator assembly, further reducing noise during motor and refrigeration equipment operation.

[0020] In some technical solutions of this utility model, optionally, the multiple through holes include a second hole, which extends from the circumferential outer surface of the damping member to the first mounting groove and communicates with the first mounting groove.

[0021] In this technical solution, the second hole extends from the circumferential outer surface of the vibration damper to the first mounting groove. This second hole reduces the transmission of motor vibration to the refrigeration equipment and also provides the vibration damper with sufficient strength, thereby reducing noise while improving the stability of the vibration damper's support for the motor. The second hole's extension from the circumferential outer surface of the vibration damper to the first mounting groove allows it to effectively attenuate vibration transmission along the circumferential direction of the stator assembly, thus weakening circumferential excitation and reducing noise during motor and refrigeration equipment operation. Furthermore, the second hole can also attenuate vibration transmission along the radial and axial directions of the stator assembly, further reducing noise during motor and refrigeration equipment operation.

[0022] The second hole is connected to the first mounting slot, which makes the second hole longer in the radial direction. This allows the second hole to more effectively attenuate the vibration transmitted along the circumferential direction of the stator assembly, further enhancing the weakening effect of the second hole on the circumferential excitation.

[0023] Optionally, the second hole is located radially outside the first mounting groove.

[0025] In this technical solution, the bracket extends in a ring shape, and a second mounting groove is provided on the inner circumference of the bracket. The stator assembly is disposed within the bracket, and the vibration damping component is disposed within the second mounting groove. The bracket then mounts and secures the motor, improving its stability during operation. The vibration damping component is disposed between the mounting ears of the bracket and the stator assembly. The vibration damping component attenuates the vibration generated by the motor from being transmitted to the bracket, and further attenuates the vibration transmitted from the motor to the refrigeration equipment, thereby reducing the noise of the motor and the refrigeration equipment during operation, and reducing the vibration of the refrigeration equipment during operation.

[0026] Optionally, the shape of the second mounting groove matches the shape of the damper.

[0027] In some technical solutions of this utility model, optionally, the circumferential outer surface of the damping member is provided with a plurality of first protrusions, and the plurality of first protrusions are in contact with the bracket.

[0028] In this technical solution, the circumferential outer surface of the vibration damper is provided with multiple first protrusions, which contact the bracket to reduce the contact area between the circumferential outer surface of the vibration damper and the bracket. While ensuring the stability of the vibration damper in supporting the stator assembly, it further reduces the vibration transmitted to the bracket, thereby reducing the noise of the motor and refrigeration equipment during operation.

[0029] Optionally, there are multiple first protrusions, each extending along the axial direction of the stator assembly, the multiple first protrusions being arranged circumferentially spaced along the stator assembly, and a gap being present between two adjacent first protrusions.

[0030] The inner side of the second mounting groove mates with the circumferential outer surface of the vibration damper. The inner side of the second mounting groove is provided with a fourth rib. There are multiple fourth ribs, and multiple fourth ribs are arranged alternately with multiple first protrusions. That is, the fourth ribs are set in the gap between two adjacent first protrusions among the multiple first protrusions.

[0031] In some technical solutions of this utility model, optionally, in the circumferential direction of the stator assembly, the second hole is disposed between two adjacent first protrusions among a plurality of first protrusions.

[0032] In this technical solution, in the circumferential direction of the stator assembly, the second hole is set between two adjacent first protrusions among a plurality of first protrusions, that is, the second hole and the first protrusions are arranged alternately, so that the vibration damper has strong rigidity and strong support capacity at the position where the first protrusion is set, and the vibration damper can effectively attenuate the transmission of vibration at the position where the second hole is set, further balancing the support capacity and vibration damping capacity of the vibration damper, improving the support stability of the vibration damper for the stator assembly, and further improving the vibration damping effect of the vibration damper.

[0034] In this technical solution, the ratio of the width of the second hole to the width of the first protrusion in the circumferential direction of the stator assembly is greater than or equal to 0.3 and less than or equal to 1, which further balances the support capacity and vibration reduction capacity of the damping component. While improving the support stability of the damping component for the stator assembly, it also further improves the vibration reduction effect of the damping component.

[0035] Optionally, in the circumferential direction of the stator assembly, the ratio of the width of the second hole to the width of the first protrusion is 0.3.

[0036] In the circumferential direction of the stator assembly, the ratio of the width of the second hole to the width of the first protrusion is 0.5.

[0041] Optionally, in some technical solutions of this utility model, a mounting platform is provided on the first axial surface of the vibration damper, and the mounting platform is provided with a first rib, which contacts the bracket.

[0042] In this technical solution, a mounting platform is provided on the first axial surface of the vibration damper. The mounting platform is provided with a first rib, which contacts the bracket, further reducing the contact area between the vibration damper and the bracket. This ensures the stability of the vibration damper's support for the stator assembly while further reducing the vibration transmitted to the bracket, thereby reducing the noise of the motor and refrigeration equipment during operation.

[0049] In this technical solution, the vibration damper is equipped with a positioning platform. The positioning platform extends along the axial direction of the stator assembly away from the support and abuts against the circumferential edge of the cover. The positioning platform can position the cover to prevent the cover from moving during the operation of the motor, thereby reducing the probability of the cover colliding with the support, reducing the risk of abnormal noise from the motor at the working point, and further reducing the noise of the motor during operation.

Detailed Implementation

[0069] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0070] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0071] The following reference Figures 1 to 6 This invention describes a motor and a refrigeration device according to some embodiments of the present invention.

[0072] In one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, a motor is provided, including a stator assembly 100, mounting ears 200, and a vibration damper 300. The mounting ears 200 are disposed on the stator assembly 100. The vibration damper 300 is provided with a first mounting groove 310, and at least a portion of the mounting ears 200 are located within the first mounting groove 310. The vibration damper 300 is provided with a plurality of through holes 320, which are arranged circumferentially around the stator assembly 100. Figure 2 Arranged in the direction indicated by the middle arrow B.

[0073] In this embodiment, the motor includes a stator assembly 100, which, when energized, can cooperate with the rotor assembly to output power.

[0074] The motor also includes a mounting ear 200, which is located on the stator assembly 100. The mounting ear 200 supports the stator assembly 100, thereby enabling the motor to be installed and fixed.

[0075] The motor also includes a vibration damper 300, which has a first mounting groove 310. At least a portion of the mounting ears 200 are located within the first mounting groove 310, meaning the vibration damper 300 is fitted onto the outside of the mounting ears 200. This vibration damper 300 supports the stator assembly 100, ensuring the stability of the motor during operation. The vibration damper 300's fitting onto the mounting ears 200 via the first mounting groove 310 facilitates assembly, simplifies the assembly process, and reduces assembly difficulty. Furthermore, the vibration damper 300's fitting onto the mounting ears 200 via the first mounting groove 310 allows it to support and dampen the stator assembly 100 in multiple directions, improving both the stability of the support and the vibration damping effect.

[0076] The vibration damper 300 is provided with multiple through holes 320 arranged circumferentially along the stator assembly 100. When vibration is transmitted to the through holes 320, it loses its transmission medium, allowing the through holes 320 to attenuate the transmission of vibration. Because the through holes 320 attenuate the transmission of vibration, the vibration generated by the motor during operation is partially attenuated by the through holes 320 on the vibration damper 300 during transmission to the refrigeration equipment, thereby improving the vibration damping effect of the vibration damper 300, reducing the noise of the refrigeration equipment during operation, and improving the quality of the refrigeration equipment.

[0077] Specifically, when the motor is working, the vibration generated by the motor will be transmitted in the form of vibration waves. When the vibration waves are transmitted to the through hole 320, they will be transmitted to the air by the damping component 300. The vibration waves will gradually weaken in the air, so that the vibration waves will not continue to be transmitted to the refrigeration equipment. In this way, the through hole 320 on the damping component 300 can attenuate the transmission of vibration.

[0078] Through hole 320 can attenuate the axial direction of stator assembly 100. Figure 2 (in the direction indicated by the middle arrow C), the radial direction of the stator assembly 100 ( Figure 2 The direction indicated by the middle arrow A) and the circumferential excitation of the stator assembly 100, i.e., the through hole 320 can attenuate the transmission of vibration.

[0079] Optionally, there are multiple mounting ears 200, which are arranged at intervals along the circumference of the stator assembly 100. The vibration damping element 300 is sleeved on the mounting ears 200. The vibration damping element 300 can effectively reduce the transmission of lateral excitation from the stator assembly 100 to the refrigeration equipment, while also giving the vibration damping element 300 good support capacity.

[0080] Optionally, the vibration damper 300 can be made of an elastic material (such as rubber or an elastomer), which has good vibration damping performance. Since elastic materials can absorb and attenuate vibration energy, the use of the vibration damper 300 can effectively reduce the vibration transmission of the motor on the support 400, protect the motor and the support 400, and extend the service life of the equipment. Of course, the vibration damper 300 can also reduce the transmission of noise, thereby improving the overall quietness of the equipment.

[0081] The hardness range of the vibration damper 300 is HS (Shore hardness) 30 to HS70.

[0082] Optionally, the opening of the first mounting groove 310 is located on the circumferential inner side of the damper 300, and the mounting ear 200 is inserted into the first mounting groove 310 through the opening of the first mounting groove 310.

[0083] Optionally, the damper 300 has a hexahedral structure, and the two sides of the damper 300 in the circumferential direction of the stator assembly 100 are planes.

[0084] This embodiment provides a motor, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0085] like Figure 1 , Figure 4 and Figure 5 As shown, the plurality of through holes 320 include a first hole 322, which extends from the circumferential sidewall of the damper 300 toward the stator assembly 100, penetrates the damper 300, and is located on the circumferential side of the first mounting groove 310.

[0086] In this embodiment, the first hole 322 extends from the circumferential sidewall of the damper 300 towards the stator assembly 100, penetrating the damper 300. The first hole 322 reduces the transmission of motor vibration to the refrigeration equipment and also provides the damper 300 with sufficient strength, thereby reducing noise while improving the stability of the damper 300 in supporting the motor. The first hole 322's extension from the circumferential sidewall of the damper 300 towards the stator assembly 100 effectively attenuates vibration transmission along the circumferential direction of the stator assembly 100, thus weakening circumferential excitation and reducing noise during motor and refrigeration equipment operation. The first hole 322 is located circumferentially to the first mounting groove 310, enabling it to attenuate vibration transmission along the circumferential direction of the stator assembly 100 while also attenuating vibration transmission along the radial direction, further reducing noise during motor and refrigeration equipment operation. Furthermore, the first hole 322 can also attenuate the vibration transmitted along the axial direction of the stator assembly 100, further reducing the noise of the motor and refrigeration equipment during operation.

[0087] This embodiment provides a motor, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0088] like Figure 1 , Figure 4 and Figure 5 As shown, the plurality of through holes 320 include a second hole 324, which extends from the circumferential outer surface 340 of the damper 300 to the first mounting groove 310 and communicates with the first mounting groove 310.

[0089] In this embodiment, the second hole 324 extends from the circumferential outer surface 340 of the damper 300 to the first mounting groove 310. The second hole 324 reduces the transmission of motor vibration to the refrigeration equipment and also provides the damper 300 with sufficient strength, thereby reducing noise while improving the stability of the damper 300 in supporting the motor. The second hole 324 effectively attenuates vibration transmission along the circumferential direction of the stator assembly 100, thus weakening circumferential excitation and reducing noise during operation of the motor and refrigeration equipment. Furthermore, the second hole 324 also attenuates vibration transmission along the radial and axial directions of the stator assembly 100, further reducing noise during operation of the motor and refrigeration equipment.

[0090] The second hole 324 is connected to the first mounting groove 310, which makes the second hole 324 have a longer length in the radial direction, thereby making the second hole 324 more effective in attenuating the vibration transmitted along the circumferential direction of the stator assembly 100, and further improving the weakening effect of the second hole 324 on the circumferential excitation.

[0091] Optionally, the second hole 324 is located radially outside the first mounting groove 310.

[0092] This embodiment provides a motor, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0093] like Figure 1 and Figure 2 As shown, the motor also includes a bracket 400, which extends in a ring shape, and a second mounting groove 420 is provided on the inner circumference of the bracket 400; the stator assembly 100 is disposed in the bracket 400, and the vibration damping component 300 is disposed in the second mounting groove 420.

[0094] In this embodiment, the bracket 400 extends in a ring shape, and a second mounting groove 420 is provided on the inner circumference of the bracket 400. The stator assembly 100 is disposed within the bracket 400, and the vibration damper 300 is disposed within the second mounting groove 420. The bracket 400 is used to install and fix the motor, improving the stability of the motor during operation. The vibration damper 300 is disposed between the bracket 400 and the mounting ears 200 of the stator assembly 100. The vibration damper 300 can attenuate the vibration generated by the motor from being transmitted to the bracket 400, and further attenuate the vibration generated by the motor from being transmitted to the refrigeration equipment, thereby reducing the noise of the motor and the refrigeration equipment during operation, and reducing the vibration of the refrigeration equipment during operation.

[0095] Optionally, the shape of the second mounting groove 420 matches the shape of the damper 300.

[0096] This embodiment provides a motor, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0097] like Figure 1 , Figure 4 and Figure 6 As shown, the circumferential outer surface 340 of the damper 300 is provided with a plurality of first protrusions 330, and the plurality of first protrusions 330 are in contact with the bracket 400.

[0098] In this embodiment, the circumferential outer surface 340 of the vibration damper 300 is provided with a plurality of first protrusions 330. The plurality of first protrusions 330 contact the bracket 400, thereby reducing the contact area between the circumferential outer surface 340 of the vibration damper 300 and the bracket 400. While ensuring the stability of the vibration damper 300 in supporting the stator assembly 100, the vibration transmitted to the bracket 400 is further reduced, thereby reducing the noise of the motor and refrigeration equipment during operation.

[0099] Optionally, there are multiple first protrusions 330, each first protrusion 330 extending along the axial direction of the stator assembly 100, the multiple first protrusions 330 being arranged circumferentially spaced along the stator assembly 100, and there being a gap between two adjacent first protrusions 330 among the multiple first protrusions 330.

[0100] The inner side of the second mounting groove 420 mates with the circumferential outer surface 340 of the damper 300. The inner side of the second mounting groove 420 is provided with a fourth rib. There are multiple fourth ribs, and the multiple fourth ribs are arranged alternately with multiple first protrusions 330. That is, the fourth ribs are set in the gap between two adjacent first protrusions 330 among the multiple first protrusions 330.

[0105] like Figure 4 and Figure 6 As shown, in the circumferential direction of the stator assembly 100, the ratio of the width W1 of the second hole 324 to the width W2 of the first protrusion 330 is greater than or equal to 0.3 and less than or equal to 1.

[0106] In this embodiment, in the circumferential direction of the stator assembly 100, the ratio of the width W1 of the second hole 324 to the width W2 of the first protrusion 330 is greater than or equal to 0.3 and less than or equal to 1, which further balances the support capacity and vibration reduction capacity of the damping member 300. While improving the support stability of the damping member 300 for the stator assembly 100, it also further improves the vibration reduction effect of the damping member 300.

[0107] Optionally, in the circumferential direction of the stator assembly 100, the ratio of the width W1 of the second hole 324 to the width W2 of the first protrusion 330 is 0.3.

The mounting platform 392 is provided with a first rib 394, which contacts the bracket 400, further reducing the contact area between the vibration damper 300 and the bracket 400. This ensures the stability of the vibration damper 300 in supporting the stator assembly 100 while further reducing the vibration transmitted to the bracket 400, thereby reducing the noise of the motor and refrigeration equipment during operation. Furthermore, the first rib 394 on the mounting platform 392 increases the friction between the vibration damper 300 and the bracket 400, further improving the support stability between the bracket 400 and the vibration damper 300.

[0116] Optionally, the second mounting groove 420 has a first support surface that mates with the first axial surface 350. The first support surface is provided with a third rib, which is arranged alternately with the first rib 394, thereby increasing the friction between the bracket 400 and the damping member 300 and improving the stability of the bracket 400 in supporting the stator assembly 100.

[0117] Optionally, the number of first ribs 394 is one, or the number of first ribs 394 is multiple.

[0119] This embodiment provides a motor, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0120] like Figure 1 and Figure 2 As shown, the motor also includes a cover 500, which covers the stator assembly 100. The cover 500 and the stator assembly 100 are arranged axially and abut against the vibration damping member 300.

[0121] In this embodiment, the motor also includes a cover 500, which covers the stator assembly 100. The cover 500 and the stator assembly 100 are arranged axially and abut against the vibration damping member 300. The cover 500 and the bracket 400 cooperate to limit the stator assembly 100, thereby further improving the stability of the motor during operation.

[0122] This embodiment provides a motor, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0123] like Figure 1 , Figure 2 and Figure 3 As shown, the vibration damper 300 is provided with a positioning platform 380, which extends along the axial direction of the stator assembly 100 away from the bracket 400 and abuts against the circumferential edge of the cover 500.

[0124] In this embodiment, the vibration damper 300 is provided with a positioning platform 380. The positioning platform 380 extends away from the support 400 along the axial direction of the stator assembly 100 and abuts against the circumferential edge of the cover 500. The positioning platform 380 can position the cover 500 to prevent the cover 500 from moving during the operation of the motor, thereby reducing the probability of the cover 500 colliding with the support 400, reducing the risk of abnormal noise from the motor at the working point, and further reducing the noise of the motor during operation.

[0125] Optionally, the positioning platform 380 extends along the axial direction of the stator assembly 100 and protrudes from the second axial surface 360 ​​of the damper 300, and the inner wall surface of the positioning platform 380 mates with the circumferential edge of the cover 500.

[0126] This embodiment provides a motor, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0127] like Figure 1 , Figure 5 and Figure 6 As shown, the second axial surface 360 ​​of the damper 300 is provided with a second rib 370, which is in contact with the cover 500.

[0128] In this embodiment, the second axial surface 360 ​​of the vibration damper 300 is provided with a second rib 370, which contacts the cover 500, thereby reducing the contact area between the vibration damper 300 and the cover 500, reducing the vibration transmitted to the cover 500, and thus reducing the noise of the motor and refrigeration equipment during operation.

[0129] Optionally, there may be multiple second ribs 370, which are arranged at circumferential intervals along the stator assembly 100.

[0130] This embodiment provides a motor, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0131] like Figure 1 , Figure 2 and Figure 4 As shown, at least a portion of the through holes 320 extend radially along the stator assembly 100; and / or at least a portion of the through holes 320 extend along the thickness direction of the damper 300. Figure 4 (Extends in the direction indicated by the middle arrow D).

[0132] In this embodiment, at least a portion of the through holes 320 extend radially along the stator assembly 100. This ensures that the through holes 320 can attenuate the transmission of vibration in the circumferential, radial, and axial directions of the stator assembly 100, and also ensures the support strength of the damper 300, thereby improving the stability of the damper 300 in supporting the stator assembly 100. Furthermore, the radial extension of at least a portion of the through holes 320 along the stator assembly 100 makes the distribution of the through holes 320 within the damper 300 more uniform, thereby balancing the strength of the damper 300 at various locations and further enhancing the support capability of the damper 300 in supporting the stator assembly 100.

[0133] At least some of the through holes 320 extend along the thickness direction of the damper 300. This ensures that the through holes 320 can attenuate the transmission of vibration in the circumferential, radial, and axial directions of the stator assembly 100, and also ensures the support strength of the damper 300, thereby improving the stability of the damper 300 in supporting the stator assembly 100. Furthermore, the fact that at least some of the through holes 320 extend along the thickness direction of the damper 300 makes the mold opening process more convenient when manufacturing the damper 300 using a mold, simplifies the mold structure for manufacturing the damper 300, reduces the difficulty of the manufacturing process of the damper 300, and improves the manufacturing feasibility of the damper 300.
