The rotor is driven to a certain speed by means such as belt dragging, and then the vibration signal is measured to calculate the unbalance value, and the unbalance amount of the rotor is adjusted to meet the qualified standard. However, there is a difference between the state of the rotor during dynamic balance testing in the related art and the operating state of the rotor in the motor, and the dynamic balance accuracy is not high. When defective products due to unqualified dynamic balance occur, it is necessary to disassemble the machine for repair, and the repair cost is high. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art or related technologies.

[0010] The sixth aspect of the present invention further provides a readable storage medium.

[0011] In view of this, the first aspect of the present invention proposes a motor, including: a housing; a rotating component, a part of the rotating component is disposed inside the housing, and along the rotation axis direction of the rotating component, both ends of the rotating component extend out of the housing; a balance processing part, disposed on the rotating component, the balance processing part is located inside the housing or outside the housing, and the dynamic balance parameters of the motor can be adjusted by operating the balance processing part. Wherein, when the balance processing part is located inside the housing, the housing is provided with an avoidance hole, the avoidance hole is correspondingly arranged with the balance processing part, and the balance processing part can be processed through the avoidance hole.

[0012] The motor provided by the present invention includes a housing, a rotating component, and a balance machining part. A part of the rotating component is arranged inside the housing, and the housing can protect the rotating component to prevent the influence of external structures or dust on the operation of the rotating component. Both ends of the rotating component extend out of the housing to realize the output of the power of the rotating component. The balance machining part is arranged on the rotating component, and among them, the balance machining part is arranged inside the housing or outside the housing. When the balance machining part is arranged outside the housing, the dynamic balance parameters of the whole motor can be detected after the motor is assembled, and the balance machining part located outside the housing can be operated to adjust the dynamic balance parameters of the whole motor. If there are unqualified products in terms of dynamic balance parameters, there is no need to disassemble the motor for repair, which reduces the manufacturing cost. When the balance machining part is located inside the housing, an avoidance hole is arranged on the housing, and the avoidance hole is arranged corresponding to the balance machining part. Then, after the motor is assembled, the dynamic balance of the whole motor is detected, and the balance machining part located inside the housing can be operated through the avoidance hole to adjust the dynamic balance parameters of the whole motor.

[0013] The motor proposed in this application arranges a balance machining part outside the housing or arranges a balance machining part inside the housing and sets an avoidance hole on the housing that can operate on the balance machining part. Then, the dynamic balance parameters of the whole motor can be adjusted after the motor is assembled, so that the dynamic balance parameters of the whole motor meet the requirements, improving the vibration situation of the motor. And when there are defective products with unqualified dynamic balance, there is no need to disassemble the machine for repair. The balance machining part outside the housing or the balance machining part inside the housing can be directly operated through the avoidance hole to adjust the dynamic balance of the whole motor. In addition, when detecting the dynamic balance of the motor after the motor is assembled, the rotating component can also be tested at the working speed, and then the dynamic balance of the motor under normal working conditions can be evaluated, effectively improving the vibration problem of the motor.

Wherein, when the balancing machining part is disposed outside the housing, the balancing machining part is disposed at at least one of the two ends of the rotating shaft. Thus, based on the overall dynamic balance test of the motor, operations can be performed on the balancing machining part to achieve the adjustment of the overall dynamic balance of the motor. When the balancing machining part is disposed inside the housing, the balancing machining part is located on the rotor. Thus, after the overall dynamic balance of the motor is detected, operations can be performed on the balancing machining part on the rotor through the avoidance hole to achieve the adjustment of the overall dynamic balance of the motor.

[0021] In some embodiments, the balancing machining part includes a balance weight.

[0022] In this embodiment, the balancing machining part includes a balance weight. After the overall dynamic balance parameters of the motor are tested, if the dynamic balance parameters need to be adjusted, operations can be performed on the balance weight to achieve the adjustment of the dynamic balance. This method does not require processing of the rotating component itself, ensuring the overall strength of the rotating component (such as the rotating shaft and the rotor).

[0023] In some embodiments, the balance weight includes a balance ring, and the balance ring is disposed around the outside of the rotating shaft.

[0024] In this embodiment, the balance ring is disposed annularly around the outside of the rotating shaft, improving the balance performance of the rotating shaft and avoiding the situation of the rotating shaft tilting due to the setting of the balance ring. At the same time, when adding or removing weight from the balance ring, it is also beneficial to improve the reliability of the dynamic balance adjustment.

The adjustment method includes: detecting the dynamic balance parameters after the motor is assembled to obtain a first detection value; when the first detection value is greater than the first parameter threshold, operating on the balancing processing unit to make the dynamic balance parameters of the motor less than or equal to the first parameter threshold.

[0034] The dynamic balance adjustment method of the motor provided by the third aspect of the present invention is to detect the dynamic balance parameters of the whole motor after the motor is assembled, and then, according to the detection results, operate on the balance processing part located outside the motor housing, or operate on the balance processing part located inside the motor through the avoidance hole, so as to adjust the dynamic balance of the whole motor, make the dynamic balance parameters of the motor less than or equal to the first parameter threshold, and further improve the vibration condition of the motor. Specifically, when the first detection value is greater than the first parameter threshold, it indicates that the dynamic balance of the motor does not meet the requirements. At this time, operate on the balance processing part to reduce the dynamic balance parameters of the motor to the first parameter threshold to meet the dynamic balance requirements of the motor.

[0035] In some embodiments, the step of detecting the dynamic balance parameters after the motor is assembled specifically includes: controlling the motor to start and rotate at the target speed.

[0036] In this embodiment, in the detection of the dynamic balance parameters of the whole motor, control the motor to start and make the motor rotate at the target speed through its own electromagnetic drive, and then detect the dynamic balance parameters of the whole motor at the target speed.

[0037] In some embodiments, the target speed includes the speed of the motor in the working state.

[0038] In this embodiment, the target speed includes the speed of the motor in the working state, that is, test the dynamic balance of the motor in the working state of the motor, so that the test conditions are closer to the use state, and the interference of the position deviation of the rotor bearing in the end cover on the dynamic balance test can be excluded; the imbalance caused by the deformation of the rotor under the action of high-speed centrifugal force can also be considered, and at the same time, the vibration caused by the imbalance at high speed is greater, which can improve the signal-to-noise ratio of the test signal.

[0039] In some embodiments, the rotating component includes a rotor. Before the step of detecting the dynamic balance parameters after the motor is assembled, it further includes: detecting the dynamic balance parameters of the rotor and obtaining a second detection value; operating on the rotor according to the second detection value to make the dynamic balance parameters of the rotor less than or equal to the second parameter threshold.

Before detecting the dynamic balance of the whole motor, it further includes detecting the dynamic balance of the rotor and operating on the rotor according to the second detection value obtained by the detection to make the dynamic balance parameters of the rotor less than or equal to the second parameter threshold, that is, first detect the dynamic balance of the rotor, and when the dynamic balance detection value does not meet the requirements, operate on the rotor to reduce its unbalance amount to a certain level, then assemble the whole motor, and then detect the dynamic balance of the whole motor to achieve high-precision dynamic balance adjustment.

[0041] In some embodiments, operating the balance machining part specifically includes: performing at least one of cutting, drilling, and dispensing on the balance machining part; operating the rotor specifically includes: performing at least one of cutting, drilling, and dispensing on the rotor.

[0042] In this embodiment, operating the balance machining part may specifically be performing at least one of cutting, drilling, and dispensing on the balance machining part to make the balance machining part heavier or lighter, thereby reducing the dynamic balance parameter. Operating the rotor specifically includes performing at least one of cutting, drilling, and dispensing on the rotor to make the rotor heavier or lighter, thereby reducing the dynamic balance parameter of the rotor.

[0043] The dynamic balance adjustment device for an electric motor according to the fourth aspect of the present invention includes a detection unit for detecting the dynamic balance parameter after the electric motor is assembled and obtaining a first detection value; and an operation unit for operating the balance machining part to make the dynamic balance parameter of the electric motor less than or equal to the first parameter threshold when the first detection value is greater than the first parameter threshold.

[0044] The dynamic balance adjustment device proposed in the fourth aspect of the present invention includes a detection unit and an operation unit. After the electric motor is assembled, the detection unit detects the dynamic balance parameter of the entire electric motor, and then the operation unit operates the balance machining part located outside the outer shell of the electric motor or operates the balance machining part located inside the electric motor through the avoidance hole according to the detection result to adjust the dynamic balance of the entire electric motor, so that the dynamic balance parameter of the electric motor is less than or equal to the first parameter threshold, thereby improving the vibration condition of the electric motor. Specifically, when the first detection value is greater than the first parameter threshold, it indicates that the dynamic balance of the electric motor does not meet the requirements.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0063] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0064] Next, refer to Figures 1 to 11 to describe a motor, a washing device, a dynamic balancing adjustment method, a device and an electronic device according to some embodiments of the present invention.

[0065] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, according to an embodiment of the present invention, the present invention provides a motor, including: a housing 1, a rotating component 2 and a balancing machining part 3.

[0066] Specifically, a part of the rotating component 2 is arranged inside the housing 1. Along the direction of the rotation axis A of the rotating component 2, both ends of the rotating component 2 extend out of the housing 1; the balancing machining part 3 is arranged on the rotating component 2. The balancing machining part 3 is located inside or outside the housing 1. By operating the balancing machining part 3, the dynamic balancing parameters of the motor can be adjusted. Among them, when the balancing machining part 3 is located inside the housing 1, the housing 1 is provided with an avoidance hole 10, and the avoidance hole 10 is arranged corresponding to the balancing machining part 3, and the balancing machining part 3 can be machined through the avoidance hole 10.

[0067] The motor provided by the present invention includes a housing 1, a rotating component 2, and a balancing processing part 3. A part of the rotating component 2 is arranged inside the housing 1, and the housing 1 can protect the rotating component 2 to prevent the influence of external structures or dust on the operation of the rotating component 2. Both ends of the rotating component 2 extend out of the housing 1 to achieve the output of the power of the rotating component 2. The balancing processing part 3 is arranged on the rotating component 2, wherein the balancing processing part 3 is arranged inside the housing 1 or outside the housing 1. When the balancing processing part 3 is arranged outside the housing 1, it is possible to detect the dynamic balance parameters of the entire motor after the motor is assembled, and it is possible to operate on the balancing processing part 3 located outside the housing 1 to adjust the dynamic balance parameters of the entire motor. If there are products with unqualified dynamic balance parameters, it is not necessary to disassemble the motor for repair, reducing the manufacturing cost. When the balancing processing part 3 is located inside the housing 1, an avoidance hole 10 is arranged on the housing 1, and the avoidance hole 10 is arranged corresponding to the balancing processing part 3. Then, after the motor is assembled, the dynamic balance of the entire motor is detected, and the balancing processing part 3 located inside the housing 1 can be operated through the avoidance hole 10 to adjust the dynamic balance parameters of the entire motor.

[0068] The motor proposed in this application arranges the balancing processing part 3 outside the housing 1 or arranges the balancing processing part 3 inside the housing 1 and sets an avoidance hole 10 on the housing 1 that can operate on the balancing processing part 3. Then, it is possible to adjust the dynamic balance parameters of the entire motor after the motor is assembled, so that the dynamic balance parameters of the entire motor meet the requirements, improving the vibration situation of the motor. And when there are defective products with unqualified dynamic balance, it is not necessary to disassemble the machine for repair. It is possible to directly operate on the balancing processing part 3 outside the housing 1 or operate on the balancing processing part 3 located inside the housing 1 through the avoidance hole 10 to adjust the dynamic balance of the entire motor. In addition, when detecting the dynamic balance of the motor after the motor is assembled, it is also possible to test the rotating component 2 at the working speed, and then evaluate the dynamic balance of the motor under normal working conditions, effectively improving the vibration problem of the motor.

[0069] It should be noted that operating on the balancing processing part 3 includes adding weight or reducing weight to the balancing processing part 3.

[0070] Optionally, operating on the balancing processing part 3 includes at least one of cutting, drilling, and dispensing on the balancing processing part 3.

[0071] As Figure 2 、 Figure 3 and Figure 4 shown, according to some embodiments of the present invention, optionally, the housing 1 includes: an outer shell 12, and the rotating component 2 is located inside the outer shell 12; end covers 14, along the direction of the rotation axis A, the end covers 14 are located at both ends of the outer shell 12. Among them, when the balancing processing part 3 is located inside the housing 1, the avoidance hole 10 is arranged on the end cover 14.

[0072] In this embodiment, the housing 1 includes a housing shell 12 and end caps 14. The end caps 14 are disposed at both ends of the housing shell 12 to form a space for accommodating the rotating member 2. Among them, the avoidance holes 10 are provided on the end caps 14 to facilitate the operation of the balance processing portion 3 and also facilitate the machining of the avoidance holes 10.

[0073] Optionally, the avoidance holes 10 are provided on at least one of the two end caps 14 at both ends of the housing shell 12.

[0074] As Figure 3 shown, according to some embodiments of the present invention, optionally, the rotating member 2 includes: a rotating shaft 20, a part of the rotating shaft 20 is disposed inside the housing shell 12, and both ends of the rotating shaft 20 extend out of the housing shell 12 through the end caps 14; a rotor 22, disposed inside the housing shell 12, and the rotor 22 is connected to the rotating shaft 20. Among them, when the balance processing portion 3 is located outside the housing 1, the balance processing portion 3 is disposed at at least one of both ends of the rotating shaft 20; when the balance processing portion 3 is disposed inside the housing shell 12, the balance processing portion 3 is disposed on the rotor 22.

[0075] In this embodiment, the rotating member 2 includes a rotating shaft 20 and a rotor 22. The rotor 22 is disposed inside the housing shell 12. Both ends of the rotating shaft 20 pass through the housing shell 12, and the rotor 22 is connected to the rotating shaft 20. Thus, the rotor 22 can drive the rotating shaft 20 to rotate. Among them, when the balance processing portion 3 is disposed outside the housing shell 1, the balance processing portion 3 is disposed at at least one of both ends of the rotating shaft 20. Thus, on the basis of testing the overall dynamic balance of the motor, the balance processing portion 3 can be operated to adjust the overall dynamic balance of the motor. When the balance processing portion 3 is disposed inside the housing shell 1, the balance processing portion 3 is located on the rotor 22. Thus, after detecting the overall dynamic balance of the motor, the balance processing portion 3 on the rotor 22 can be operated through the avoidance holes 10 to adjust the overall dynamic balance of the motor.

[0076] According to some embodiments of the present invention, optionally, when the balance processing portion 3 is disposed on the rotor 22, the balance processing portion 3 is a part of the rotor 22.

[0077] In this embodiment, when the balance processing portion 3 is disposed on the rotor 22, the balance processing portion 3 is a part of the rotor 22. After the housing 1 of the motor is assembled, by operating the rotor 22, the adjustment of the overall dynamic balance of the motor is realized, so that the dynamic balance after the motor is assembled also meets the dynamic balance requirements.

[0078] It can be understood that the balance processing portion 3 is a part of the rotor 22. After testing the overall dynamic balance of the motor, if it is necessary to adjust the dynamic balance parameters, the rotor 22 can be directly operated through the avoidance holes 10 to adjust the overall dynamic balance of the motor.

[0079] Of course, the balancing processing unit 3 can also be a separate component provided on the rotor 22.

[0080] As Figure 6 and Figure 7 shown, according to some embodiments of the present invention, optionally, the balancing processing unit 3 includes a balance weight 30.

[0081] In this embodiment, the balancing processing unit 3 includes a balance weight 30. After testing the overall dynamic balance parameters of the motor, if the dynamic balance parameters need to be adjusted, the balance weight 30 can be operated to achieve the adjustment of the dynamic balance. This method does not require processing the rotating component 2 itself, ensuring the overall strength of the rotating component 2 (such as the rotating shaft 20 and the rotor 22).

[0082] As Figure 8 shown, according to some embodiments of the present invention, optionally, the balance weight 30 includes a balance ring 300, and the balance ring 300 is disposed around the outside of the rotating shaft 20.

[0083] In this embodiment, the balance ring 300 is arranged in a ring shape around the outside of the rotating shaft 20, improving the balance performance of the rotating shaft 20 and avoiding the occurrence of the situation where the rotating shaft 20 is inclined due to the setting of the balance ring 300. At the same time, when adding or removing weight from the balance ring 300, it is also beneficial to improve the reliability of the dynamic balance adjustment.

[0084] As Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, according to some embodiments of the present invention, optionally, the balancing processing unit 3 includes a pulley 32, and the pulley 32 is provided on the rotating shaft 20.

[0085] In this embodiment, the balancing processing unit 3 includes a pulley 32. The pulley 32 is arranged on the rotating shaft 20, and the rotation of the rotating shaft 20 can drive the pulley 32 to rotate, thereby realizing the operation of other structures connected to the pulley 32. In the motor proposed in this application, the pulley 32 can not only connect other components to achieve power transmission, but also realize the adjustment of dynamic balance, saving the space occupied by the balancing processing unit 3 and being beneficial to the miniaturized design of the structure.

[0086] It can be understood that when the motor is applied to an electrical appliance, the motor can be connected to other structures through the pulley 32 to drive other structures.

[0087] Optionally, the motor is applied to a washing device, and the pulley 32 drives the drum of the washing device to rotate to realize the treatment of clothes.

[0088] Optionally, as Figure 8As shown, one end of the rotating shaft 20 is provided with a pulley 32, and the other end is provided with a balance ring 300.

[0089] According to some embodiments of the present invention, optionally, when the balance processing part 3 is located outside the housing 1, the balance processing part 3 and the rotating part 2 are of an integral structure.

[0090] In this embodiment, when the balance processing part 3 is arranged outside the housing 1, the balance processing part 3 and the rotating part 2 are of an integral structure. Through the design of the integral structure, the connection strength between the balance processing part 3 and the rotating part 2 is ensured, and the situation that the dynamic balance of the whole motor changes due to the change of the position of the balance processing part 3 during the operation of the motor is avoided.

[0091] It can be understood that the balance processing part 3 can be connected to the rotating part 2 by welding or bonding.

[0092] According to some embodiments of the present invention, optionally, the balance processing part 3 includes a metal processing part or a plastic processing part.

[0093] In this embodiment, the balance processing part 3 includes a metal processing part or a plastic processing part, that is, the balance processing part 3 can be a plastic product, so as to facilitate the weight addition or weight removal treatment of the balance processing part 3. The balance processing part 3 can also be a metal product to increase the connection strength between the balance processing part 3 and the rotating part 2.

[0094] According to an embodiment of the present invention, a washing device is further provided, including: a motor as proposed in any of the above embodiments.

[0095] The washing device provided by the present invention includes the motor proposed in any of the above embodiments, and thus has all the beneficial effects of the motor.

[0096] Optionally, the washing device includes any one of a washing machine and a washing and drying integrated machine. Specifically, it can be a pulsator washing machine or a drum washing machine.

[0097] According to an embodiment of the present invention, a method for adjusting the dynamic balance of a motor is further provided, which is used for the motor proposed in any of the above items.

[0098] As Figure 9 shown, a flow schematic diagram of the method for adjusting the dynamic balance of the motor is shown:

[0099] Step 402: Detect the dynamic balance parameters after the motor is assembled and obtain the first detection value;

[0100] Step 404: When the first detection value is greater than the first parameter threshold, operate on the balance processing part so that the dynamic balance parameters of the motor are less than or equal to the first parameter threshold.

[0101] For the dynamic balance adjustment method of the motor provided by the present invention, after the motor is assembled, the dynamic balance parameters of the whole motor are detected. Then, according to the detection results, operations are performed on the balance processing part located outside the motor housing, or operations are performed on the balance processing part located inside the motor through the avoidance holes, so as to adjust the dynamic balance of the whole motor, make the dynamic balance parameters of the motor less than or equal to the first parameter threshold, and further improve the vibration condition of the motor. Specifically, when the first detection value is greater than the first parameter threshold, it indicates that the dynamic balance of the motor does not meet the requirements. At this time, operations are performed on the balance processing part to reduce the dynamic balance parameters of the motor to the first parameter threshold to meet the dynamic balance requirements of the motor.

[0102] It should be noted that in this application, the dynamic balance of the whole motor is detected, and then operations are performed on the balance processing part according to the first detection value to make the balance processing part heavier or lighter, so that the dynamic balance parameters of the whole motor meet the requirements, improving the vibration condition of the motor. And when there are defective products with unqualified dynamic balance, there is no need to disassemble the machine for repair. Operations can be directly performed on the balance processing part outside the machine shell or on the balance processing part inside the machine shell through the avoidance holes to adjust the dynamic balance of the whole motor. In addition, when detecting the dynamic balance of the motor after the motor is assembled, it is also possible to test the rotating components at the working speed, and then evaluate the dynamic balance of the motor under the normal working state, effectively improving the vibration problem of the motor.

[0103] Optionally, performing operations on the balance processing part includes performing weight addition or weight reduction processing on the balance processing part.

[0104] Optionally, the first parameter threshold can be set according to the actual situation.

[0105] Optionally, the first parameter threshold includes the dynamic balance grade.

[0106] According to some embodiments of the present invention, optionally, the step of detecting the dynamic balance parameters after the motor is assembled specifically includes: controlling the motor to start and rotate at the target speed.

[0107] In this embodiment, during the detection of the dynamic balance parameters of the whole motor, the motor is controlled to start, and the motor is made to rotate at the target speed through its own electromagnetic drive, and then the dynamic balance parameters of the whole motor are detected at the target speed.

[0108] Optionally, the target speed is set according to the actual situation. The target speed can be the speed of the motor in the working state, or other set values, which can be less than the speed in the working state or greater than the speed in the working state.

[0109] According to some embodiments of the present invention, optionally, the target speed includes the speed of the motor in the working state.

[0110] In this embodiment, the target speed includes the speed of the motor when it is in the working state. That is, the dynamic balance of the motor is tested under the working state of the motor, so that the test conditions are closer to the use state, and the interference of the position deviation of the bearing of the rotor in the end cover on the dynamic balance test can be excluded; the imbalance caused by the deformation of the rotor under the action of high-speed centrifugal force can also be taken into account. At the same time, the vibration caused by the imbalance amount at high speed is greater, and the signal-to-noise ratio of the test signal can be improved.

[0111] It can be understood that the speed of the motor in the working state, that is, the speed of the motor when the motor is applied to an electrical device and works, enables the rotor to reach the use speed under the drive of the motor itself.

[0112] Among them, the speed of the motor in the working state can be one or multiple. For example, when the motor is applied to an electrical device, since the electrical device has multiple modes, the motor correspondingly has multiple working states, so that the motor has different speeds in different working states, and the target speed can be at least one of the speeds in different working states.

[0113] According to some embodiments of the present invention, optionally, the rotating component includes a rotor. Before the step of detecting the dynamic balance parameters after the motor is assembled, it further includes: detecting the dynamic balance parameters of the rotor and obtaining a second detection value; operating the rotor according to the second detection value so that the dynamic balance parameters of the rotor are less than or equal to a second parameter threshold.

[0114] In this embodiment, the rotating component includes a rotor. Before detecting the dynamic balance of the whole motor, it further includes detecting the dynamic balance of the rotor and operating the rotor according to the second detection value obtained from the detection, so that the dynamic balance parameters of the rotor are less than or equal to the second parameter threshold. That is, first detect the dynamic balance of the rotor, and when the dynamic balance detection value does not meet the requirements, operate the rotor to reduce its imbalance amount to a certain level, then assemble the whole motor, and then detect the dynamic balance of the whole motor to achieve high-precision dynamic balance adjustment.

[0115] It can be understood that when the second detection value is greater than the second parameter threshold, the rotor is operated so that the dynamic balance parameters of the rotor are less than or equal to the second parameter threshold.

[0116] It should be noted that the second parameter threshold is a preset parameter and can be a dynamic balance grade.

[0117] According to some embodiments of the present invention, optionally, operating the balance processing part specifically includes: performing at least one of cutting, drilling, and gluing on the balance processing part; operating the rotor specifically includes: performing at least one of cutting, drilling, and gluing on the rotor.

[0118] In this embodiment, the balance processing part is operated, specifically, at least one of cutting, drilling, and dispensing on the balance processing part can be performed to make the balance processing part heavier or lighter, thereby reducing the dynamic balance parameter. Operating on the rotor specifically includes performing at least one of cutting, drilling, and dispensing on the rotor to make the rotor heavier or lighter, thereby reducing the dynamic balance parameter of the rotor.

[0119] Such as Figure 10 As shown, according to an embodiment of the present invention, a dynamic balance adjustment device 500 for a motor is provided, including a detection unit 502 for detecting the dynamic balance parameter after the motor is assembled and obtaining a first detection value; an operation unit 504 for operating on the balance processing part when the first detection value is greater than a first parameter threshold to make the dynamic balance parameter of the motor less than or equal to the first parameter threshold.

[0120] The dynamic balance adjustment device 500 proposed by the present invention includes a detection unit 502 and an operation unit 504. After the motor is assembled, the detection unit 502 detects the dynamic balance parameter of the whole motor, and then the operation unit 504 operates on the balance processing part located outside the motor housing or operates on the balance processing part located inside the motor through an avoidance hole according to the detection result to realize the adjustment of the dynamic balance of the whole motor, so that the dynamic balance parameter of the motor is less than or equal to the first parameter threshold, thereby improving the vibration condition of the motor. Specifically, when the first detection value is greater than the first parameter threshold, it indicates that the dynamic balance of the motor does not meet the requirements. At this time, the balance processing part is operated to reduce the dynamic balance parameter of the motor to the first parameter threshold to meet the dynamic balance requirements of the motor.

[0121] It should be noted that this application performs dynamic balance detection on the whole motor, and then operates on the balance processing part according to the first detection value to make the balance processing part heavier or lighter, thereby making the dynamic balance parameter of the whole motor meet the requirements, improving the vibration condition of the motor, and when there are defective products with unqualified dynamic balance, there is no need to disassemble the machine for repair. The balance processing part outside the machine shell or the balance processing part located inside the machine shell can be directly operated through the avoidance hole to adjust the dynamic balance of the whole motor. In addition, when detecting the dynamic balance of the motor after the motor is assembled, it is also possible to test the rotating parts at the working speed, and then evaluate the dynamic balance of the motor under the normal working state, effectively improving the vibration problem of the motor.

[0122] Optionally, operating on the balance processing part includes performing a weight addition or weight reduction process on the balance processing part.

[0123] Optionally, the first parameter threshold can be set according to the actual situation.

[0124] Optionally, the first parameter threshold includes a dynamic balance grade.

[0125] According to some embodiments of the present invention, optionally, the step of the detection unit 502 detecting the dynamic balance parameters after the motor assembly is completed specifically includes: controlling the motor to start and rotate at a target speed.

[0126] In this embodiment, during the detection of the dynamic balance parameters of the entire motor, the motor is controlled to start, and the motor is driven by its own electromagnetic force to rotate at a target speed, and then the dynamic balance parameters of the entire motor are detected at the target speed.

[0127] Optionally, the target speed is set according to the actual situation. The target speed can be the speed of the motor in the working state, or other set values, which can be less than the speed in the working state or greater than the speed in the working state.

[0128] According to some embodiments of the present invention, optionally, the target speed includes the speed of the motor in the working state.

[0129] In this embodiment, the target speed includes the speed of the motor in the working state, that is, the dynamic balance of the motor is tested in the working state of the motor, making the test conditions closer to the use state, and it can eliminate the interference of the position deviation of the rotor bearing in the end cover on the dynamic balance test; the imbalance caused by the deformation of the rotor under the action of high-speed centrifugal force can also be considered, and at the same time, the vibration caused by the imbalance amount at high speed is greater, which can improve the signal-to-noise ratio of the test signal.

[0130] It can be understood that the speed of the motor in the working state, that is, the speed of the motor when the motor is applied to an electrical device to work, enables the rotor to reach the use speed under the drive of the motor itself.

[0131] Among them, the speed of the motor in the working state can be one or more. For example, when the motor is applied to an electrical device, since the electrical device has multiple modes, the motor correspondingly has multiple working states, so that the motor has different speeds in different working states, and the target speed can be at least one of the speeds in different working states.

[0132] According to some embodiments of the present invention, optionally, the rotating component includes a rotor. Before the step of the detection unit 502 detecting the dynamic balance parameters after the motor assembly is completed, the detection unit 502 is further configured to: detect the dynamic balance parameters of the rotor and obtain a second detection value; the operation unit 504 is further configured to: operate the rotor according to the second detection value so that the dynamic balance parameters of the rotor are less than or equal to the second parameter threshold.

[0133] In this embodiment, the rotating component includes a rotor. Before performing a dynamic balance detection on the entire motor, it further includes performing a dynamic balance detection on the rotor, and based on the second detection value obtained from the detection, operating on the rotor such that the dynamic balance parameter of the rotor is less than or equal to the second parameter threshold. That is, first perform a dynamic balance detection on the rotor, and when the dynamic balance detection value does not meet the requirements, operate on the rotor to reduce its unbalance amount to a certain level, then assemble the entire motor, and then perform a dynamic balance detection on the entire motor to achieve high-precision dynamic balance adjustment.

[0134] It can be understood that in the case where the second detection value is greater than the second parameter threshold, operate on the rotor to make the dynamic balance parameter of the rotor less than or equal to the second parameter threshold.

[0135] It should be noted that the second parameter threshold is a preset parameter and can be a dynamic balance grade.

[0136] According to some embodiments of the present invention, optionally, the operation of the operation unit 504 on the balance processing unit specifically includes: performing at least one of cutting, drilling, and dispensing on the balance processing unit; the operation of the operation unit 504 on the rotor specifically includes: performing at least one of cutting, drilling, and dispensing on the rotor.

The operation on the rotor specifically includes performing at least one of cutting, drilling, and dispensing on the rotor to make the rotor heavier or lighter, thereby reducing the dynamic balance parameter of the rotor.

[0138] As Figure 11 shown, according to an embodiment of the present invention, there is provided an electronic device 600, including: the dynamic balance adjustment device 500 proposed in any one of the above; and / or a processor 602 and a memory 604, the memory 604 stores a program or instruction that can run on the processor 602, and when the program or instruction is executed by the processor 602, it implements the steps of the dynamic balance adjustment method of the motor proposed in any one of the above. Therefore, it has all the beneficial effects of the above dynamic balance device and / or the dynamic balance adjustment method of the motor, which will not be elaborated here.

[0139] According to an embodiment of the present invention, there is provided a readable storage medium, on which a program or instruction is stored, and when the program or instruction is executed by the processor 602, it executes the dynamic balance adjustment method of the motor proposed in any one of the above. Therefore, it has all the beneficial effects of the dynamic balance adjustment method of the motor, which will not be elaborated here.

[0140] In a specific application, the dynamic balance test of the motor is carried out after the end cover 14 is assembled. The test is carried out on a dynamic balance bench, and the motor is driven electromagnetically to rise to a stable speed.

[0141] Optionally, the motor is provided with a component (such as the balance machining part 3) that can be balanced and machined outside the end cover 14. The balance machining part 3 can be an independent weight-removing end ring (such as the balance ring 300), or can be combined with structures such as the pulley 32. The material of the weight-removing component can be a metal product or a plastic product. The balance machining part 3 can perform balance machining by means of weight removal or weight addition. The balance machining part 3 can be present at one end or both ends of the rotating shaft 20.

[0142] According to the embodiments provided by the present application, the overall dynamic balance of the motor is closer to the use state of the motor in the dynamic balance test: the interference of the position deviation of the bearings of the rotor 22 in the end cover 14 to the dynamic balance test is excluded; the rotor 22 can reach the use speed under the drive of the motor itself, and the imbalance generated by the deformation of the rotor 22 under the action of the high-speed centrifugal force can be considered. At the same time, the vibration caused by the imbalance amount at high speed is greater, which can improve the signal-to-noise ratio of the test signal.

[0143] Optionally, the overall dynamic balance of the motor can be combined with the conventional dynamic balance of the rotor 22. After reducing the imbalance amount of the rotor 22 to a certain level through the conventional dynamic balance of the rotor 22, the high-precision dynamic balance can be achieved through the overall dynamic balance process. In the dynamic balance process of the rotor 22 in the related art, if the vibration of the motor cannot meet the standard due to dynamic balance reasons, the motor needs to be disassembled for repair, and the repair cost is high and the qualification rate is low. However, the overall dynamic balance proposed by the present application can directly adjust the balance of the motor and reduce the repair cost.

[0144] Optionally, the present application also proposes a design scheme of the rotor 22 that is matched with the overall dynamic balance scheme of the motor, and the rotor 22 can be machined secondarily in the assembled state of the motor.

[0145] Optionally, the balance machining part 3 does not necessarily need to be located outside the motor end cover 14, and the rotor 22 can also be machined by opening holes in the end cover 14, but the overall dynamic balance test needs to be carried out after the end cover 14 is assembled.
