Description
Technical Field
[0001] The utility model relates to the technical field of motors, and in particular to a motor and a household appliance. Background Art
[0002] Motors typically generate a certain amount of vibration during operation. The current solution is to install a rubber pad between the motor and bracket to isolate the motor from the bracket and reduce vibration using its elastic properties. However, in related technologies, the rubber pad and bracket are in surface contact, resulting in poor vibration reduction when vibration occurs. Utility Model Content
[0003] The utility model aims to at least solve the technical problem of poor vibration reduction effect existing in the prior art or related art.
[0004] In view of this, an embodiment of a first aspect of the present invention provides a motor.
[0005] An embodiment of a second aspect of the present invention provides a household appliance.
[0006] In order to achieve the above-mentioned purpose, an embodiment of the first aspect of the present invention provides a motor, including: a stator assembly; a mounting ear, arranged on the stator assembly; a vibration damping member, sleeved outside the mounting ear; wherein, the outer surface of the vibration damping member is provided with at least one vibration damping rib.
[0007] The motor proposed in this utility model includes a stator assembly, mounting ears, a vibration-damping member, and vibration-damping ribs. The stator assembly is fixed and generates a magnetic field to drive the coaxially arranged rotor to rotate, thereby balancing the motor's moment of inertia and reducing vibration caused by eccentricity. Furthermore, the mounting ears are provided on the stator assembly, specifically on the stator assembly housing, and can be used to secure the motor structure to a bracket or mounting plate.
[0008] It can be understood that the mounting ears can be flat surfaces or protruding structures extending from the stator assembly housing, and multiple mounting ears are often provided to enhance the fixing effect.
[0009] It should be emphasized that since vibration is generated when the motor is running, the rigid connection of the mounting ear may transmit the vibration to the bracket. Therefore, this application additionally provides a vibration damper. By placing the vibration damper on the outside of the mounting ear, its shape is designed to wrap around the mounting ear to form a protective and isolation layer, which can reduce the transmission of vibration generated by the motor when it is running to the outside world.
[0010] The vibration damper can be made of an elastic material (such as rubber or elastomer) with excellent vibration damping properties. Because elastic materials can absorb and attenuate vibration energy, the use of the vibration damper can effectively reduce the vibration transmission from the motor to the bracket, protecting the motor and bracket and extending the service life of the equipment. Of course, the vibration damper also reduces the transmission of noise, thereby improving the overall quietness of the equipment.
[0011] Furthermore, the outer surface of the vibration damper is provided with one or more vibration-damping ribs. The action of the vibration-damping ribs can significantly reduce the direct contact area between the vibration damper and the motor bracket or mounting plate. By reducing the contact area, the rigid contact points are reduced, the vibration transmission efficiency is reduced, and the vibration reduction effect is further enhanced. Because the ribs are compressed when in contact with the bracket, the elastic deformation of the rubber absorbs some of the vibration energy. This raised structural design improves the overall elasticity of the vibration damper and enhances its ability to absorb small vibrations. In turn, the vibration-damping ribs enable the vibration damper to have better deformation capabilities in the vertical direction, which not only improves its impact resistance, but also makes the vibration transmission path more dispersed, avoiding excessive vibration caused by concentration in a single location.
[0012] The vibration-damping ribs may be small strip-shaped or columnar structures protruding from the surface, with irregular or regular shape distribution.
[0013] It should be noted that the mounting ears can be directly fixed to the outer shell of the stator assembly. They are usually extensions of the stator assembly, located on the outer periphery of the stator assembly, and are used to fix the motor to the external structure. The vibration damper wraps around the mounting ears in a sleeve manner, fitting tightly with the mounting ears, thereby isolating the mounting ears from the motor bracket or mounting plate, weakening the rigid connection between the two, and thus better absorbing vibrations. The vibration damper contacts the motor bracket or mounting plate through the ribs on its outer surface. Due to the rib structure on the surface of the vibration damper, the contact area is reduced and the contact points are more dispersed, thereby effectively reducing the efficiency of vibration transmission outward.
[0014] In some technical solutions, optionally, the rotor is arranged on the radial inner side of the stator assembly, and the mounting ears protrude radially outward from the outer peripheral surface of the stator assembly along the stator assembly; wherein, in the axial direction of the stator assembly, there is a gap between the mounting ears and any end surface of the stator assembly.
[0015] In this technical solution, the rotor is located on the inner side of the stator assembly, the mounting ears are located on the outer side of the stator assembly, and the mounting ears are located in the middle part of the stator assembly. The mounting ears protrude outward from the outer peripheral surface of the stator assembly along the radial direction of the stator assembly. The outward protrusion design of the mounting ears provides a larger contact area, thereby enhancing the fixation stability between the motor and the support structure. In the axial direction of the stator assembly, there is a gap between the mounting ears and any end face of the stator assembly. The mounting ears do not directly contact the end face of the stator assembly. The middle part helps to reduce the transmission of vibrations generated by the operation of the motor to the bracket or mounting plate. It can be understood that the gap can act as a buffer zone to reduce the efficiency of vibration transmission and further enhance the overall vibration reduction performance.
[0016] The overall design significantly reduces the vibration and noise during motor operation by combining the rotor, stator assembly, mounting ears and gaps, thereby improving the quietness of the equipment.
[0017] In some technical solutions, optionally, the vibration damping component specifically includes: a vibration damping groove, the shape of which is adapted to the shape of the mounting ear; wherein the vibration damping rib is arranged on the outer surface of the groove wall of the vibration damping groove and / or the outer surface of the groove bottom of the vibration damping groove.
[0018] In this technical solution, the vibration damper is in the shape of a groove, specifically a vibration damping groove. By adapting the shape of the vibration damping groove to the shape of the mounting ear, the vibration damper can be wrapped around the outside of the mounting ear, reducing direct contact between the mounting ear and the outside world, thereby effectively isolating the vibration source.
[0019] Furthermore, the vibration-damping ribs are located on the outer surface of at least one of the groove wall and the groove bottom of the vibration-damping groove. The vibration-damping ribs located on the groove wall, specifically the raised portions on the side of the vibration-damping groove, primarily function to reduce radial vibration. The vibration-damping ribs located on the groove bottom, specifically the ribs at the bottom of the vibration-damping groove, primarily function to reduce axial vibration.
[0020] The vibration-damping ribs on the slot walls and bottom provide a multi-dimensional vibration-damping effect. The ribs on the slot walls reduce radial vibration from the motor, while the ribs on the slot bottom help buffer axial vibration. This design effectively reduces vibration in multiple directions and improves overall vibration reduction.
[0021] The vibration-damping ribs elastically deform under vibration, absorbing and damping vibration energy. Especially during motor operation, the ribs disperse vibrations through small deformations, preventing them from being concentrated in a single spot.
[0022] Due to the presence of the vibration-damping ribs, the direct contact area between the vibration-damping component and the motor bracket or mounting plate is significantly reduced, reducing the rigid contact points, thereby avoiding the efficient transmission of vibration and allowing the vibration to be dispersed and absorbed.
[0023] It can be understood that the vibration damping groove is specially designed for the mounting ear. Therefore, during installation, the vibration damping groove can completely wrap the mounting ear, the inner wall of the vibration damping groove fits tightly with the mounting ear, and the vibration damping rib is located on the outer surface of the vibration damping groove, that is, the part that contacts the motor bracket or the mounting plate.
[0024] The precise matching of the vibration-damping grooves and mounting ears, along with the multi-directional layout of the vibration-damping ribs, effectively reduces vibration transmission and enhances the stability and durability of the equipment. The overall structural design not only significantly reduces vibration and noise during motor operation, but also, through careful material selection and structural optimization, improves vibration damping and enhances equipment life.
[0025] In some technical solutions, optionally, it further includes: a sealing lip, which is provided at the notch of the vibration damping groove.
[0026] In this technical solution, a sealing lip is provided at the notch of the vibration damping groove. On the one hand, the sealing lip is tightened to prevent the vibration damper from being easily removed when installed on the mounting ear. On the other hand, after being installed on the motor bracket, the sealing lip seals the mounting gap between the mounting ear and the motor bracket, thereby preventing impurities from entering the mounting gap and causing motor vibration and noise. At the same time, the seal prevents the vibration damper from undergoing an oxidation reaction with oxygen in the air at high temperatures, thereby improving the service life of the vibration damper.
[0027] It can be understood that during installation, the mounting ear is inserted into the vibration damping groove, and the sealing lip will be squeezed, thereby forming a good sealing effect. At the same time, the elastic characteristics of the sealing lip can also play an auxiliary vibration reduction role to a certain extent, absorb part of the vibration energy, and further improve the vibration reduction effect.
[0028] In some technical solutions, optionally, the vibration-damping member and the vibration-damping rib are integrally formed.
[0029] In this technical solution, the vibration damping parts and vibration damping ribs are processed through an integrated molding process. On the one hand, the overall material of the vibration damping parts and the vibration damping ribs is uniform, and the force deformation and vibration damping effect are relatively uniform, which effectively reduces the possibility of local vibration damping effects being too low. On the other hand, defects are less likely to occur during the production and processing process, and production efficiency is high. At the same time, potential weaknesses and failure points are also reduced, so that the vibration damping parts can better withstand vibration and pressure during long-term use and have better durability.
[0030] In some technical solutions, optionally, the vibration-damping ribs are strip-shaped, at least part of the vibration-damping ribs are arranged on the outer surface of the vibration-damping member along the radial direction of the stator assembly, and at least part of the vibration-damping ribs are arranged on the outer surface of the vibration-damping member along the axial direction of the stator assembly.
[0031] In this technical solution, the strip-shaped vibration-damping ribs are designed to better deform. Some of these ribs are positioned radially and axially on the outer surface of the vibration damper. Understandably, these strip-shaped vibration-damping ribs deform more significantly when subjected to forces perpendicular to their direction of projection. By providing both axial and radial vibration-damping ribs on the outer surface of the vibration damper, the overall deformation of the vibration damper is more uniform when subjected to vibrations in different directions.
[0032] In some technical solutions, optionally, the cross-sectional profile of the vibration-damping rib is arc-shaped and / or broken-line-shaped.
[0033] In this technical solution, the cross-sectional profile of the vibration-damping rib can be an arc, a broken line, or even a combination of both. The arc-shaped or broken line-shaped vibration-damping rib creates a point of concentrated stress when in contact with the motor bracket or other mounting component. The rib deforms first at this point, enabling it to more effectively absorb and buffer energy when subjected to vibration, thereby reducing vibration transmission.
[0034] In some technical solutions, optionally, the stator assembly is arranged on the radial inner side of the rotor, and the mounting ears protrude radially outward from the outer peripheral surface of the end of the stator assembly along the stator assembly.
[0035] In this technical solution, the stator assembly is located radially inward of the rotor, and the mounting ears are located at the radial ends of the stator assembly and protrude radially outward. It can be understood that in an external rotor motor, with the stator assembly inside and the rotor outside, the connection between the stator assembly and the motor bracket is located at the end of the stator assembly. This connection method allows the mounting ears to directly connect to the external bracket and mounting parts, facilitating motor assembly.
[0036] In some technical solutions, optionally, it also includes: a part to be installed, which is provided with a mounting groove that is adapted to the shape of the mounting ear; and a mounting cover, which is arranged corresponding to the mounting groove, and when the mounting ear is located in the mounting groove, the mounting cover cooperates with the notch of the mounting groove to limit the movement of the mounting ear.
[0037] In this technical solution, a mounting member is provided with a mounting groove that matches the shape of the mounting ears. The shape and size of the mounting groove are designed based on the mounting ears to ensure that the mounting ears fit tightly within them. The mounting groove allows the motor to be connected to the mounting member via the mounting ears.
[0038] Furthermore, when the mounting ears are located within the mounting slots, the mounting cover engages with the slotted openings to restrict movement of the ears. The mounting cover can be connected to the mounting component via bolts, snaps, or other fastening methods, firmly securing the ears within the slots and preventing them from dislodging. This further improves the reliability and stability of motor installation, ensuring that the ears do not loosen or fall off due to vibration or other external forces during motor operation.
[0039] In summary, the mounting groove on the component to be mounted provides a mounting position for the mounting ear, and the mounting cover cooperates with the mounting groove to jointly ensure the fixation of the mounting ear, thereby improving the stability and reliability of the motor installation.
[0040] In some technical solutions, optionally, there are multiple mounting ears, and the multiple mounting ears are evenly spaced around the axis of the stator assembly and arranged on the outer peripheral surface of the stator assembly.
[0041] In this technical solution, a plurality of mounting ears are evenly spaced around the axis of the stator assembly and arranged on the outer peripheral surface of the stator assembly.
[0042] It should be added that the provision of multiple mounting ears increases the number of fixed points for connecting the stator assembly to the external structure, making the motor more stable after installation, and better able to withstand the various forces and torques generated during motor operation, thereby reducing motor shaking and displacement.
[0043] The mounting ears are evenly spaced, so that the stator assembly is subjected to more uniform force in all directions during installation, avoiding deformation or damage of the stator assembly due to uneven force, and improving the overall structural strength and reliability of the motor.
[0044] An embodiment of a second aspect of the present application provides a household appliance, comprising the motor of the first aspect described above.
[0045] Since the household appliance includes any of the above-mentioned motors, the noise generated during the operation of the household appliance can be reduced by the vibration-damping member on the mounting ear of the motor, thereby achieving a noise reduction effect.

DETAILED DESCRIPTION
[0054] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.
[0055] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.
[0056] Refer to the following Figures 1 to 6 Some embodiments according to the present invention are described.
[0057] like Figure 1 、 Figure 2 As shown, a motor 100 proposed in this embodiment includes a motor structure 101, mounting ears 106, a vibration damper 108, and vibration-damping ribs 1082. The motor structure 101 includes a fixed stator assembly 104. The stator assembly 104 generates a magnetic field to drive the coaxial rotor 102 to rotate, thereby balancing the motor's rotational inertia and reducing vibration caused by eccentricity. Furthermore, mounting ears 106 are provided on the stator assembly 104, specifically on the housing of the stator assembly 104. The mounting ears 106 secure the motor structure 101 to a bracket or mounting plate.
[0058] It is understood that the mounting ears 106 may be a flat surface or a protruding structure extending from the housing of the stator assembly 104 , and a plurality of mounting ears 106 are often provided to enhance the fixing effect.
[0059] It should be emphasized that since the motor will generate vibration when it is running, the rigid connection of the mounting ear 106 may transmit the vibration to the bracket. Therefore, this application additionally provides a vibration damper 108. By putting the vibration damper 108 on the outside of the mounting ear 106, its shape is designed to wrap around the mounting ear 106, forming a protective and isolation layer, which can reduce the vibration generated when the motor is running and transmit it to the outside world.
[0060] Vibration damper 108 can be made of an elastic material (such as rubber or elastomer) with excellent vibration damping properties. Because elastic materials can absorb and attenuate vibration energy, the use of vibration damper 108 can effectively reduce the transmission of vibration from the motor to the bracket, protecting the motor and bracket and extending the service life of the device. Furthermore, vibration damper 108 can also reduce noise transmission, thereby improving the overall quietness of the device.
[0061] Furthermore, the outer surface of the vibration damper 108 is provided with one or more vibration-damping ribs 1082. Under the action of the vibration-damping ribs 1082, the direct contact area between the vibration damper 108 and the motor bracket or mounting plate can be significantly reduced. By reducing the contact area, the rigid contact points are reduced, the vibration transmission efficiency is reduced, and the vibration reduction effect is further enhanced. Because the ribs are compressed when in contact with the bracket, the elastic deformation of the rubber absorbs part of the vibration energy. This raised structural design improves the overall elasticity of the vibration damper 108 and enhances its ability to absorb small vibrations. In addition, the vibration-damping ribs 1082 can make the vibration damper have better deformation ability in the vertical direction, which not only improves the impact resistance, but also makes the vibration transmission path more dispersed, avoiding excessive vibration caused by concentration in a certain location.
[0062] The vibration-damping ribs 1082 may be small strip-shaped or columnar structures protruding from the surface, with irregular or regular shape distribution.
[0063] It should be added that the mounting ear 106 can be directly fixed to the outer shell of the stator assembly 104. It is usually an extension of the stator assembly 104 and is located on the outer peripheral side of the stator assembly 104, and is used to fix the motor to the external structure. The vibration damper 108 wraps around the mounting ear 106 in a sleeve manner and fits tightly with the mounting ear 106, thereby isolating the mounting ear 106 from the motor bracket or mounting plate, weakening the rigid connection between the two, so as to better absorb vibration. The vibration damper 108 contacts the motor bracket or mounting plate through the ribs on its outer surface. Since the surface of the vibration damper 108 has a rib structure, the contact area is reduced and the contact points are more dispersed, thereby effectively weakening the efficiency of vibration transmission to the outside.
[0064] In some embodiments, optionally, the rotor 102 is located on the inner side of the stator assembly 104, the mounting ears 106 are located on the outer side of the stator assembly 104, and the mounting ears 106 are located in the middle part of the stator assembly 104. The mounting ears 106 protrude outward from the outer peripheral surface of the stator assembly 104 along the radial direction of the stator assembly 104. The outward protrusion design of the mounting ears 106 provides a larger contact area, thereby enhancing the fixation stability between the motor and the support structure. In the axial direction of the stator assembly 104, there is a gap 103 between the mounting ears 106 and any end surface of the stator assembly 104. The mounting ears 106 do not directly contact the end surface of the stator assembly 104. The middle part helps to reduce the transmission of vibrations generated by the operation of the motor to the bracket or mounting plate. It can be understood that the gap 103 can act as a buffer zone to reduce the efficiency of vibration transmission and further enhance the overall vibration reduction performance.
[0065] The overall design significantly reduces vibration and noise during motor operation by combining the rotor 102, the stator assembly 104, the mounting ears 106 and the gap 103, thereby improving the quietness of the equipment.
[0066] In a specific embodiment, the vibration damping member 108 is groove-shaped, specifically a vibration damping groove. By adapting the shape of the vibration damping groove to the shape of the mounting ear 106, the vibration damping member 108 can be wrapped around the outside of the mounting ear 106, reducing direct contact between the mounting ear 106 and the outside world, thereby effectively isolating the vibration source.
[0067] Furthermore, the vibration-damping ribs 1082 are located on the outer surface of at least one of the groove wall and the groove bottom of the vibration-damping groove. The vibration-damping ribs located on the groove wall, specifically the raised portions on the side of the vibration-damping groove, primarily function to reduce radial vibration. The vibration-damping ribs located on the groove bottom, specifically the ribs at the bottom of the vibration-damping groove, primarily function to reduce axial vibration.
[0068] The vibration-damping ribs 1082, located on the slot walls and bottom, provide a multi-dimensional vibration-damping effect. The ribs on the slot walls reduce radial vibration from the motor, while the ribs on the slot bottom help buffer axial vibration. This design effectively reduces vibration in multiple directions, improving the overall vibration-damping effect.
[0069] The vibration-damping ribs 1082 can elastically deform under vibration, thereby absorbing and attenuating vibration energy. In particular, during motor operation, the presence of the ribs can disperse vibrations through small deformations, preventing vibrations from concentrating on a single point.
[0070] Due to the presence of the vibration-damping ribs 1082, the direct contact area between the vibration-damping member 108 and the motor bracket or mounting plate is significantly reduced, reducing rigid contact points, thereby avoiding efficient transmission of vibration and allowing vibration to be dispersed and absorbed.
[0071] It can be understood that the vibration-damping groove 1084 is specially designed for the mounting ear 106. Therefore, during installation, the vibration-damping groove can completely wrap the mounting ear 106, and the inner wall of the vibration-damping groove 1084 fits tightly with the mounting ear 106, while the vibration-damping rib 1082 is located on the outer surface of the vibration-damping groove 1084, that is, the part that contacts the motor bracket or the mounting plate.
[0072] The precise matching of the vibration-damping grooves 1084 and mounting ears 106, along with the multi-directional layout of the vibration-damping ribs 1082, effectively reduces vibration transmission and enhances the stability and durability of the equipment. This overall structural design not only significantly reduces vibration and noise during motor operation, but also, through careful material selection and structural optimization, improves vibration damping and enhances equipment lifespan.
[0073] Furthermore, the shape of the vibration-damping groove 1084 may be slightly smaller than the mounting ear 106 , forming an interference fit with the mounting ear 106 .
[0074] In another specific embodiment, Figure 3 and Figure 4 As shown, it also includes: by providing a sealing lip 1086 at the notch 1088 of the vibration damping groove 1084, on the one hand, the vibration damping member 108 is not easy to fall off when installed on the mounting ear 106 through the fastening of the sealing lip 1086; on the other hand, after being installed on the motor bracket, the installation gap between the mounting ear 106 and the motor bracket is sealed by the sealing lip 1086, thereby preventing impurities from entering the installation gap and causing motor vibration and noise. At the same time, the sealing prevents the vibration damping member 108 from undergoing an oxidation reaction with oxygen in the air at high temperature, thereby improving the service life of the vibration damping member 108.
[0075] It can be understood that during installation, the mounting ear 106 is inserted into the vibration damping groove 1084, and the sealing lip 1086 will be squeezed, thereby forming a good sealing effect. At the same time, the elastic characteristics of the sealing lip 1086 can also play an auxiliary vibration reduction role to a certain extent, and can absorb part of the vibration energy to further improve the vibration reduction effect.
[0076] In some embodiments, optionally, the vibration damping member 108 and the vibration damping rib 1082 are processed through an integrated molding process. On the one hand, the overall material of the vibration damping member 108 and the vibration damping rib 1082 is uniform, and the force deformation and vibration damping effect are relatively uniform, which effectively reduces the possibility of a situation where the local vibration damping effect is too low. On the other hand, defects are less likely to occur during the production and processing process, and the production efficiency is high. At the same time, potential weaknesses and failure points are also reduced, so that the vibration damping member can better withstand vibration and pressure during long-term use and has better durability.
[0077] In some embodiments, strip-shaped vibration-damping ribs 1082 can be optionally provided on the outer surface of the vibration damper 108 in radial and axial directions relative to the stator assembly 104 to achieve better deformation. It is understood that strip-shaped vibration-damping ribs 1082 experience greater deformation when subjected to forces perpendicular to the direction of their projection. By providing axial and radial vibration-damping ribs 1082 on the outer surface of the vibration damper 108, the overall deformation of the vibration damper 108 is more uniform when subjected to vibrations in different directions.
[0078] In some embodiments, the cross-sectional profile of the vibration-damping rib 1082 can optionally be an arc, a broken line, or even a combination of both. The arc-shaped or broken line-shaped vibration-damping rib 1082 forms a point of concentrated stress when in contact with the motor bracket or other components to be mounted. At this point of concentrated stress, the vibration-damping rib 1082 deforms first, enabling the vibration-damping rib 1082 to more effectively absorb and buffer energy when subjected to vibration, thereby reducing vibration transmission.
[0079] In one specific embodiment, the stator assembly 104 is located radially inward of the rotor 102, and the mounting ears 106 are provided at the radial ends of the stator assembly 104 and protrude radially outward. It will be appreciated that in a motor with an outer rotor 102, with the stator assembly 104 inside and the rotor 102 outside, the connection between the stator assembly 104 and the motor bracket is located at the end of the stator assembly 104. This connection allows the mounting ears 106 to directly connect to the external bracket or mounting components, facilitating motor assembly.
[0080] like Figure 5 As shown, in another specific embodiment, it further includes: a to-be-mounted member 110, on which a mounting groove 1102 is provided that matches the shape of the mounting ear 106; Figure 6 As shown, it also includes: a mounting cover 112, which is arranged corresponding to the mounting slot 1102. When the mounting ear 106 is located in the mounting slot 1102, the mounting cover 112 cooperates with the notch of the mounting slot 1102 to limit the movement of the mounting ear 106.
[0081] A mounting member 110 is provided, and a mounting groove 1102 is formed on the mounting member, which matches the shape of the mounting ears 106. The shape and size of the mounting groove 1102 are designed based on the mounting ears 106 to ensure that the mounting ears 106 can be tightly embedded therein. The mounting groove 1102 allows the motor to be connected to the mounting member via the mounting ears 106.
[0082] Furthermore, when mounting ear 106 is positioned within mounting slot 1102, mounting cover 112 engages with the notch of mounting slot 1102 to restrict movement of mounting ear 106. Mounting cover 112 can be connected to mounting member 110 via bolts, snaps, or other fastening methods, firmly securing mounting ear 106 within mounting slot 1102 and preventing it from dislodging. This further improves the reliability and stability of motor installation, ensuring that mounting ear 106 does not become loose or fall off due to vibration or other external forces during motor operation.
[0083] In summary, the mounting groove 1102 on the mounting component provides a mounting position for the mounting ear 106 , and the mounting cover 112 cooperates with the mounting groove 1102 to ensure the fixation of the mounting ear 106 , thereby improving the stability and reliability of the motor installation.
[0084] In some embodiments, optionally, as Figure 1 As shown, a plurality of mounting ears 106 are evenly spaced around the axis 105 of the stator assembly 104 and disposed on the outer circumference of the stator assembly 104 .
[0085] It should be added that the provision of multiple mounting ears 106 increases the fixing points for connecting the stator assembly 104 with the external structure, making the motor more stable after installation, and better able to withstand the various forces and torques generated during motor operation, thereby reducing the shaking and displacement of the motor.
[0086] The mounting ears 106 are evenly spaced, so that the stator assembly 104 is subjected to more uniform force in all directions during installation, thereby avoiding deformation or damage of the stator assembly 104 due to uneven force, and improving the overall structural strength and reliability of the motor.
[0087] Furthermore, for a DC motor or a two-phase AC motor, two mounting ears 106 are provided, spaced 180 degrees apart. For a three-phase AC motor, three mounting ears 106 are provided, spaced 120 degrees apart, and positioned directly opposite the center of the magnet on the stator assembly 104. Because the motor's rotation is driven by a magnetic field, and the force-bearing component on the stator assembly 104 is the magnet, arranging the mounting ears 106 directly opposite the center of the magnet reduces the torsional moment on the stator assembly 104 housing and reduces vibration of the stator assembly 104.
[0088] In a specific embodiment, a three-phase AC motor is proposed. The motor consists of a stator and a rotor, with the stator on the outside and the rotor on the inside. The stator is provided with mounting ears, and the number of mounting ears is 3, which are evenly arranged on the outside of the stator at intervals of 120 degrees. The motor bracket is provided with mounting grooves corresponding to the shape of the mounting ears, and the motor is fixed to the motor bracket through the mounting ears. The vibration-damping rubber pad sleeve (i.e., the vibration-damping part) is on the motor mounting ear, wrapping the mounting ear, thereby achieving a vibration-damping effect between the motor and the motor bracket. The main feature of the vibration-damping rubber pad is that the outer surface of the rubber pad is provided with a plurality of raised structures (i.e., ribs). These raised structures significantly reduce the contact area between the outer surface of the rubber pad and the motor bracket or the mounting plate, thereby improving the overall elasticity of the rubber pad, achieving a better vibration-damping effect, and better reducing the vibration transmission and noise radiation of the motor.
[0089] The present application provides an embodiment of a household appliance, including the motor 100 in any of the above embodiments. During the operation of the household appliance, the noise generated can be reduced by the vibration damping parts on the mounting ears of the motor 100, thereby achieving a noise reduction effect.
[0090] Among them, the motor 100 in the household appliance is mainly used as a power source to drive the moving parts in the household appliance. For example, the household appliances include but are not limited to washing machines, vacuum cleaners, and electric toothbrushes. Among them, the motor 100 in the washing machine is used to rotate the washing tub, the motor 100 in the vacuum cleaner is used to drive the fan to generate suction, and the motor 100 in the electric toothbrush is used to vibrate the brush head.
