The rotor is driven to a certain speed by belt dragging or other methods, and then the vibration signal is measured to calculate the imbalance value, and the imbalance of the rotor is adjusted to meet the qualified standard. However, there is a difference between the state of the rotor during the dynamic balance test and the running state of the rotor in the motor in the related technology, and the dynamic balance accuracy is not high. When defective products due to unqualified dynamic balance appear, the machine needs to be disassembled for repair, and the repair cost is high. Summary of the invention
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.
[0004] To this end, a first aspect of the present invention provides an electric motor.

[0008] A fifth aspect of the present invention also provides an electronic device.
[0009] The sixth aspect of the present invention also provides a readable storage medium.
[0010] In view of this, the first aspect of the present invention proposes a motor, comprising: a casing; a rotating component, a part of which is arranged in the casing, and along the rotation axis direction of the rotating component, both ends of the rotating component extend out of the casing; a balancing processing part, which is arranged on the rotating component, and the balancing processing part is located in the casing or outside the casing, and the dynamic balancing parameters of the motor can be adjusted by operating the balancing processing part, wherein, when the balancing processing part is located in the casing, an avoidance hole is provided on the casing, and the avoidance hole is arranged corresponding to the balancing processing part, and the balancing processing part can be processed through the avoidance hole.
[0011] The motor provided by the present invention comprises a casing, a rotating part and a balancing processing part, wherein a part of the rotating part is arranged in the casing, the casing can protect the rotating part, prevent the external structure or dust from affecting the operation of the rotating part, and the two ends of the rotating part extend out of the casing to realize the output of the power of the rotating part. The balancing processing part is arranged on the rotating part, wherein the balancing processing part is arranged in the casing or arranged outside the casing. In the case where the balancing processing part is arranged outside the casing, the dynamic balancing parameters of the motor as a whole can be detected after the motor is assembled, and the balancing processing part located outside the casing can be operated to adjust the dynamic balancing parameters of the motor as a whole. If a product with unqualified dynamic balancing parameters appears, the motor does not need to be disassembled for repair, thereby reducing the manufacturing cost. In the case where the balancing processing part is located inside the casing, an avoidance hole is arranged on the casing, so that the avoidance hole is arranged corresponding to the balancing processing part, and then after the motor is assembled, the motor as a whole is dynamically balanced, and the balancing processing part located in the casing can be operated through the avoidance hole to adjust the dynamic balancing parameters of the motor as a whole.
[0012] The motor proposed in the present application is provided with a balancing processing part outside the casing or a balancing processing part inside the casing and an avoidance hole on the casing that can operate the balancing processing part, so that the dynamic balancing parameters of the motor as a whole can be adjusted after the motor is assembled, so that the dynamic balancing parameters of the motor as a whole meet the requirements, and the vibration of the motor is improved. In addition, when defective products with unqualified dynamic balance appear, there is no need to dismantle the machine for repair. The balancing processing part outside the casing or the balancing processing part inside the casing can be directly operated through the avoidance hole to adjust the dynamic balance of the motor as a whole. In addition, when the dynamic balance of the motor is detected after the motor is assembled, the rotating parts can also be tested at the operating speed, so as to evaluate the dynamic balance of the motor under normal working conditions, and effectively improve the vibration problem of the motor.
[0013] The motor provided according to the present invention may also have the following additional technical features:
[0014] In some possible designs, the casing includes: an outer shell, in which the rotating component is located; and end covers, which are located at both ends of the outer shell along the direction of the rotation axis, wherein when the balancing processing part is located in the casing, the avoidance holes are provided on the end covers.
[0015] In this design, the casing includes an outer shell and end covers, wherein the end covers are arranged at both ends of the outer shell to form a space for accommodating rotating parts, wherein avoidance holes are arranged on the end covers to facilitate operation of the balancing processing part and also facilitate processing of the avoidance holes.
[0016] In some possible designs, the rotating parts include: a rotating shaft, a part of which is arranged in the outer shell, and both ends of the rotating shaft extend to the outside of the outer shell from the end covers; a rotor, which is arranged in the outer shell and connected to the rotating shaft, wherein when the balancing processing part is located outside the casing, the balancing processing part is arranged at least one of the two ends of the rotating shaft; when the balancing processing part is arranged in the outer shell, the balancing processing part is arranged on the rotor.
[0017] In this design, the rotating part includes a rotating shaft and a rotor. The rotor is arranged in the housing, and the two ends of the rotating shaft pass through the housing. The rotor is connected to the rotating shaft, and the rotor can drive the rotating shaft to rotate. Among them, in the case where the balancing processing part is arranged outside the housing, the balancing processing part is arranged at least at one of the two ends of the rotating shaft, and then the balancing processing part can be operated on the basis of testing the overall dynamic balance of the motor to adjust the overall dynamic balance of the motor. In the case where the balancing processing part is arranged in the housing, the balancing processing part is located on the rotor, and then after the overall dynamic balance of the motor is detected, the balancing processing part on the rotor can be operated through the avoidance hole to adjust the overall dynamic balance of the motor.
[0018] In some possible designs, when the balancing processing portion is provided on the rotor, the balancing processing portion is a part of the rotor.
[0019] In this design, when the balancing processing part is set on the rotor, the balancing processing part is a part of the rotor. After the motor casing is assembled, the overall dynamic balance of the motor is adjusted by operating the rotor, so that the dynamic balance of the motor after assembly also meets the dynamic balance requirements.
[0020] In some possible designs, the balancing processing portion includes a balancing weight.
[0021] In this design, the balancing processing part includes a balancing block. After testing the overall dynamic balancing parameters of the motor, if the dynamic balancing parameters need to be adjusted, the balancing block can be operated to achieve dynamic balance adjustment. This method does not require processing of the rotating parts themselves, thereby ensuring the overall strength of the rotating parts (such as the shaft and rotor).
[0022] In some possible designs, the balancing weight includes a balancing ring, which is arranged around the outside of the rotating shaft.
[0023] In this design, the balance ring is arranged in a ring shape around the outside of the shaft, which improves the balance performance of the shaft and avoids the shaft tilting due to the setting of the balance ring. At the same time, when the balance ring is weighted or unweighted, it is also helpful to improve the reliability of dynamic balance adjustment.
[0024] In some possible designs, the balancing processing part includes a pulley, and the pulley is arranged on the rotating shaft.
[0025] In this design, the balancing processing part includes a pulley, which is arranged on a rotating shaft. The rotation of the rotating shaft can drive the pulley to rotate, thereby realizing the operation of other structures connected to the pulley. The motor proposed in this application has a pulley that can be connected to other components to realize power transmission and can also realize dynamic balance adjustment, which saves the space occupied by the balancing processing part and is conducive to the miniaturization of the structure.
[0026] In some possible designs, when the balancing processing part is located outside the housing, the balancing processing part and the rotating component are an integrated structure.
[0027] In this design, when the balancing processing part is arranged outside the casing, the balancing processing part and the rotating component are an integrated structure. Through the design of the integrated structure, the connection strength between the balancing processing part and the rotating component is guaranteed, thereby avoiding the change of the overall dynamic balance of the motor due to the change of the position of the balancing processing part during the operation of the motor.
[0028] In some possible designs, the balancing processing portion includes a metal processing portion or a plastic processing portion.
[0029] In this design, the balancing processing part includes a metal processing part or a plastic processing part, that is, the balancing processing part can be a plastic product to facilitate weighting or weight reduction of the balancing processing part, and the balancing processing part can also be a metal product to increase the connection strength between the balancing processing part and the rotating part.
[0030] According to a second aspect of the present invention, a washing device is also proposed, comprising: a motor as proposed in any of the above technical solutions.
[0031] The washing device provided in the second aspect of the present invention comprises the motor proposed in any of the above technical solutions and therefore has all the beneficial effects of the motor.
[0032] According to a third aspect of the present invention, a method for dynamic balancing adjustment of a motor is also proposed, which is used for a motor as proposed in any one of the first aspects. The adjustment method includes: after the motor is assembled, performing a dynamic balancing parameter detection and obtaining a first detection value; when the first detection value is greater than a first parameter threshold, operating the balancing processing part so that the dynamic balancing parameter of the motor is less than or equal to the first parameter threshold.
[0033] The third aspect of the present invention provides a method for adjusting the dynamic balance of a motor. After the motor is assembled, the dynamic balance parameters of the motor as a whole are detected. Then, according to the detection result, the balance processing part located outside the motor housing is operated, or the balance processing part located inside the motor is operated through the avoidance hole to adjust the dynamic balance of the motor as a whole, so that the dynamic balance parameter of the motor is less than or equal to the first parameter threshold, thereby improving the vibration of the motor. Specifically, when the first detection value is greater than the first parameter threshold, it means that the dynamic balance of the motor does not meet the requirements. At this time, the balance processing part is operated so that the dynamic balance parameter of the motor is reduced to the first parameter threshold to meet the dynamic balance requirements of the motor.
[0034] In some possible designs, the step of detecting the dynamic balancing parameters after the motor is assembled specifically includes: controlling the motor to start and rotate at a target speed.
[0035] In this design, during the detection of the dynamic balancing parameters of the motor as a whole, the motor is controlled to start and rotate at a target speed through its own electromagnetic drive, and then the dynamic balancing parameters of the motor as a whole are detected at the target speed.
[0036] In some possible designs, the target speed includes the speed of the motor when it is in a working state.
[0037] In this design, the target speed includes the speed when the motor is in working condition, that is, the dynamic balance of the motor is tested when the motor is in working condition, so that the test conditions are closer to the use condition, and the interference of the position deviation of the rotor bearing in the end cover on the dynamic balance test can be eliminated; 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 at high speed is greater, which can improve the signal-to-noise ratio of the test signal.
[0038] In some possible designs, the rotating part includes a rotor, and before the step of detecting the dynamic balancing parameters after the motor is assembled, the step also includes: detecting the dynamic balancing parameters of the rotor and obtaining a second detection value; operating the rotor according to the second detection value so that the dynamic balancing parameters of the rotor are less than or equal to the second parameter threshold.
[0039] In this design, the rotating parts include a rotor. Before the dynamic balancing test is performed on the entire motor, a dynamic balancing test is also performed on the rotor, and based on a second detection value obtained by the test, the rotor is operated so that the dynamic balancing parameter of the rotor is less than or equal to a second parameter threshold value. That is, the rotor is first dynamically balanced, and when the dynamic balancing test value does not meet the requirements, the rotor is operated to reduce the imbalance to a certain level, and then the whole motor is assembled and then the dynamic balancing test is performed on the whole motor to achieve high-precision dynamic balancing adjustment.
[0040] In some possible designs, operating the balancing processing part specifically includes: performing at least one of cutting, drilling, and gluing on the balancing processing part; operating the rotor specifically includes: performing at least one of cutting, drilling, and gluing on the rotor.
[0041] In this design, the operation on the balancing processing part may be at least one of cutting, drilling, and gluing on the balancing processing part, so as to increase or reduce the weight of the balancing processing part, thereby reducing the dynamic balancing parameters. The operation on the rotor may be at least one of cutting, drilling, and gluing on the rotor, so as to increase or reduce the weight of the rotor, thereby reducing the dynamic balancing parameters of the rotor.
[0042] According to the fourth aspect of the present invention, the dynamic balancing adjustment device for a motor includes a detection unit for detecting dynamic balancing parameters and obtaining a first detection value after the motor is assembled; and an operating unit for operating a balancing processing part so that the dynamic balancing parameters of the motor are less than or equal to the first parameter threshold when the first detection value is greater than the first parameter threshold.
[0043] The dynamic balance adjustment device proposed in the fourth aspect of the present invention includes a detection unit and an operating unit. After the motor is assembled, the detection unit detects the dynamic balance parameters of the motor as a whole. Then, according to the detection result, the operating unit operates the balance processing part located outside the motor housing, or operates the balance processing part located inside the motor through the avoidance hole, so as to adjust the dynamic balance of the motor as a whole, so that the dynamic balance parameter of the motor is less than or equal to the first parameter threshold, thereby improving the vibration of the motor. Specifically, when the first detection value is greater than the first parameter threshold, it means that the dynamic balance of the motor does not meet the requirements. At this time, the balance processing part is operated so that the dynamic balance parameter of the motor is reduced to the first parameter threshold to meet the dynamic balance requirements of the motor.
[0044] According to the fifth aspect of the present invention, the electronic device includes: a dynamic balance adjustment device as proposed in any one of the above items; and / or a processor and a memory, wherein the memory stores a program or instruction that can be run on the processor, and when the program or instruction is executed by the processor, the steps of the dynamic balance adjustment method of the motor as proposed in any one of the above items are implemented. Therefore, all the beneficial effects of the above dynamic balance device or dynamic balance detection method are obtained, which will not be repeated here.
[0045] According to the sixth aspect of the present invention, the readable storage medium stores a program or instruction, and when the program or instruction is executed by the processor, the method for adjusting the dynamic balance of the motor as proposed in any one of the above items is executed. Therefore, it has all the beneficial effects of the dynamic balance detection method, which will not be repeated here.

[0062] In the following description, many specific details are set forth to facilitate 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 protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0063] Refer to the following Figures 1 to 11 A motor, a washing device, a dynamic balancing adjustment method, a device and an electronic device according to some embodiments of the present invention are described.
[0064] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the present invention provides a motor, including: a housing 1, a rotating component 2 and a balancing processing part 3.
[0065] Specifically, a portion of the rotating component 2 is arranged in the casing 1, and along the direction of the rotation axis A of the rotating component 2, both ends of the rotating component 2 extend out of the casing 1; the balancing processing part 3 is arranged on the rotating component 2, and the balancing processing part 3 is located in the casing 1 or outside the casing 1, and the dynamic balancing parameters of the motor can be adjusted by operating the balancing processing part 3, wherein, when the balancing processing part 3 is located in the casing 1, an avoidance hole 10 is provided on the casing 1, and the avoidance hole 10 is arranged corresponding to the balancing processing part 3, and the balancing processing part 3 can be processed through the avoidance hole 10.
[0066] The motor provided by the present invention includes a casing 1, a rotating component 2 and a balancing processing part 3, a part of the rotating component 2 is arranged in the casing 1, the casing 1 can protect the rotating component 2 to prevent external structures or dust from affecting the operation of the rotating component 2, and both ends of the rotating component 2 extend out of the casing 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 in the casing 1 or outside the casing 1. In the case where the balancing processing part 3 is arranged outside the casing 1, the dynamic balancing parameters of the entire motor can be detected after the motor is assembled, and the balancing processing part 3 located outside the casing 1 can be operated to adjust the dynamic balancing parameters of the entire motor. If a product with unqualified dynamic balancing parameters occurs, the motor does not need to be disassembled for repair, thereby reducing the manufacturing cost. When the balancing processing part 3 is located inside the casing 1, an avoidance hole 10 is provided on the casing 1 so that the avoidance hole 10 is provided corresponding to the balancing processing part 3. After the motor is assembled, a dynamic balance test is performed on the entire motor, and the balancing processing part 3 located in the casing 1 can be operated through the avoidance hole 10 to adjust the dynamic balance parameters of the entire motor.
[0067] The motor proposed in the present application is provided with a balancing processing part 3 outside the casing 1 or a balancing processing part 3 is provided inside the casing 1 and an avoidance hole 10 is provided on the casing 1 for operating the balancing processing part 3, so that the dynamic balancing parameters of the motor as a whole can be adjusted after the motor is assembled, so that the dynamic balancing parameters of the motor as a whole meet the requirements, and the vibration of the motor is improved. In addition, when defective products with unqualified dynamic balance appear, there is no need to dismantle the machine for repair. The balancing processing part 3 outside the casing 1 or the balancing processing part 3 located inside the casing 1 can be directly operated through the avoidance hole 10 to adjust the dynamic balance of the motor as a whole. In addition, when the dynamic balance of the motor is detected after the motor is assembled, the rotating component 2 can also be tested at the working speed, so as to evaluate the dynamic balance of the motor under normal working conditions, and effectively improve the vibration problem of the motor.
[0068] It should be noted that operating the balancing portion 3 includes adding weight to or reducing weight of the balancing portion 3 .
[0069] Optionally, the balancing processing part 3 is operated, including performing at least one of cutting, drilling, and gluing on the balancing processing part 3 .
[0070] like Figure 2 , Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, optionally, the casing 1 includes: an outer shell 12, and the rotating component 2 is located inside the outer shell 12; and end covers 14, which are located at both ends of the outer shell 12 along the direction of the rotation axis A, wherein when the balancing processing part 3 is located inside the casing 1, the avoidance hole 10 is provided on the end cover 14.
[0071] In this embodiment, the casing 1 includes an outer shell 12 and an end cover 14, and the end cover 14 is arranged at both ends of the outer shell 12 to form a space for accommodating the rotating part 2, wherein the avoidance hole 10 is arranged on the end cover 14 to facilitate the operation of the balancing processing part 3 and at the same time, it is also convenient for the processing of the avoidance hole 10.
[0072] Optionally, the avoidance hole 10 is provided on at least one of the two end covers 14 at both ends of the housing 12 .
[0073] like Figure 3 As shown, according to some embodiments of the present invention, optionally, the rotating component 2 includes: a rotating shaft 20, a part of which is disposed in the outer shell 12, and both ends of the rotating shaft 20 extend to the outside of the outer shell 12 from the end cover 14; a rotor 22, which is disposed in the outer shell 12, and the rotor 22 is connected to the rotating shaft 20, wherein, when the balancing processing part 3 is located outside the casing 1, the balancing processing part 3 is disposed at least one of the two ends of the rotating shaft 20; when the balancing processing part 3 is disposed in the outer shell 12, the balancing processing part 3 is disposed on the rotor 22.
[0074] In this embodiment, the rotating component 2 includes a rotating shaft 20 and a rotor 22. The rotor 22 is arranged in the housing 12. Both ends of the rotating shaft 20 pass through the housing 12. The rotor 22 is connected to the rotating shaft 20, and the rotor 22 can drive the rotating shaft 20 to rotate. In the case where the balancing processing part 3 is arranged outside the housing 12, the balancing processing part 3 is arranged at least at one of the two ends of the rotating shaft 20, and the balancing processing part 3 can be operated on the basis of testing the overall dynamic balance of the motor to adjust the overall dynamic balance of the motor. In the case where the balancing processing part 3 is arranged in the housing 12, the balancing processing part 3 is located on the rotor 22, and the balancing processing part 3 on the rotor 22 can be operated through the avoidance hole 10 after the overall dynamic balance of the motor is detected to adjust the overall dynamic balance of the motor.
[0075] According to some embodiments of the present invention, optionally, when the balancing portion 3 is provided on the rotor 22 , the balancing portion 3 is a part of the rotor 22 .
[0076] In this embodiment, when the balancing processing portion 3 is set on the rotor 22, the balancing processing portion 3 is a part of the rotor 22. After the motor casing 1 is assembled, the rotor 22 is operated to adjust the overall dynamic balance of the motor, so that the dynamic balance of the motor after assembly also meets the dynamic balance requirements.
[0077] It is understandable that the balancing processing portion 3 is a part of the rotor 22. After the dynamic balancing test of the motor as a whole, if the dynamic balancing parameters need to be adjusted, the rotor 22 can be directly operated through the avoidance hole 10 to achieve the adjustment of the dynamic balance of the motor as a whole.
[0078] Of course, the balancing portion 3 may also be a separate component provided on the rotor 22 .
[0079] like Figure 6 and Figure 7 As shown, according to some embodiments of the present invention, optionally, the balancing processing part 3 includes a balancing block 30 .
[0080] In this embodiment, the balancing processing part 3 includes a balancing block 30. After the overall dynamic balancing parameters of the motor are tested, if the dynamic balancing parameters need to be adjusted, the balancing block 30 can be operated to achieve dynamic balance adjustment. This method does not require processing of the rotating component 2 itself, thereby ensuring the overall strength of the rotating component 2 (such as the shaft 20 and the rotor 22).
[0081] like Figure 8 As shown, according to some embodiments of the present invention, optionally, the balancing weight 30 includes a balancing ring 300 , and the balancing ring 300 is disposed around the outside of the rotating shaft 20 .
[0082] In this embodiment, the balance ring 300 is arranged in a ring shape around the outer side of the rotating shaft 20, which improves the balance performance of the rotating shaft 20 and avoids the situation where the rotating shaft 20 is tilted due to the arrangement of the balance ring 300. At the same time, when the balance ring 300 is weighted or unweighted, it is also helpful to improve the reliability of dynamic balance adjustment.
[0083] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, optionally, the balancing processing part 3 includes a pulley 32 , and the pulley 32 is disposed on the rotating shaft 20 .
[0084] In this embodiment, the balancing processing part 3 includes a pulley 32, which is arranged on the rotating shaft 20. 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 be connected to other components to realize power transmission and can also realize dynamic balance adjustment, which saves the space occupied by the balancing processing part 3 and is conducive to the miniaturized design of the structure.
[0085] It is understandable that when the motor is applied to an electrical device, the motor can be connected to other structures via the pulley 32 to drive the other structures.
[0086] Optionally, the motor is applied to a washing device, and drives the drum of the washing device to rotate via the pulley 32 to achieve processing of clothes.
[0087] Alternatively, if Figure 8As shown, a pulley 32 is provided at one end of the rotating shaft 20, and a balance ring 300 is provided at the other end.
[0088] According to some embodiments of the present invention, optionally, when the balancing portion 3 is located outside the housing 1 , the balancing portion 3 and the rotating component 2 are an integrated structure.
[0089] In this embodiment, when the balancing processing part 3 is arranged outside the casing 1, the balancing processing part 3 and the rotating component 2 are an integrated structure. Through the design of the integrated structure, the connection strength between the balancing processing part 3 and the rotating component 2 is guaranteed, thereby avoiding the change of the overall dynamic balance of the motor due to the change of the position of the balancing processing part 3 during the operation of the motor.
[0090] It can be understood that the balancing portion 3 can be connected to the rotating component 2 by welding or by adhesive bonding.
[0091] According to some embodiments of the present invention, optionally, the balancing processed part 3 includes a metal processed part or a plastic processed part.
[0092] In this embodiment, the balancing processing part 3 includes a metal processing part or a plastic processing part, that is, the balancing processing part 3 can be a plastic product, so as to facilitate weighting or weight reduction processing of the balancing processing part 3, and the balancing processing part 3 can also be a metal product to increase the connection strength between the balancing processing part 3 and the rotating part 2.
[0093] According to one embodiment of the present invention, a washing device is also provided, comprising: a motor as provided in any of the above embodiments.
[0094] The washing device provided by the present invention comprises the motor proposed in any of the above embodiments and therefore has all the beneficial effects of the motor.
[0095] Optionally, the washing device includes any one of a washing machine and a washer-dryer, and may be a pulsator washing machine or a drum washing machine.
[0096] According to an embodiment of the present invention, a method for adjusting the dynamic balance of a motor is also provided, which is used for the motor as provided in any one of the above items.
[0097] like Fig. 9 As shown, a schematic diagram of the process flow of the dynamic balance adjustment method of the motor is shown:
[0098] Step 402: After the motor is assembled, a dynamic balancing parameter is detected and a first detection value is obtained;
[0099] Step 404: When the first detection value is greater than the first parameter threshold, the balancing processing unit is operated to make the dynamic balancing parameter of the motor less than or equal to the first parameter threshold.
[0100] The method for adjusting the dynamic balance of a motor provided by the present invention detects the dynamic balance parameters of the motor as a whole after the motor is assembled, and then operates the balance processing part located outside the motor housing according to the detection result, or operates the balance processing part located inside the motor through the avoidance hole, so as to adjust the dynamic balance of the motor as a whole, so that the dynamic balance parameter of the motor is less than or equal to the first parameter threshold, thereby improving the vibration of the motor. Specifically, when the first detection value is greater than the first parameter threshold, it means that the dynamic balance of the motor does not meet the requirements. At this time, the balance processing part is operated so that the dynamic balance parameter of the motor is reduced to the first parameter threshold to meet the dynamic balance requirements of the motor.
[0101] It should be noted that the present application performs a dynamic balance test on the motor as a whole, and then operates the balancing processing part according to the first detection value, so that the balancing processing part is weighted or lightened, thereby making the dynamic balance parameters of the motor as a whole meet the requirements, improving the vibration of the motor, and when defective products with unqualified dynamic balance appear, there is no need to dismantle the machine for repair. The balancing processing part outside the casing or the balancing processing part inside the casing can be operated directly through the avoidance hole to adjust the dynamic balance of the motor as a whole. In addition, when the dynamic balance of the motor is tested after the motor is assembled, the rotating parts can also be tested at the operating speed, thereby evaluating the dynamic balance of the motor under normal working conditions, effectively improving the vibration problem of the motor.
[0102] Optionally, operating the balancing portion includes weighting or lightening the balancing portion.
[0103] Optionally, the first parameter threshold may be set according to actual conditions.
[0104] Optionally, the first parameter threshold includes a dynamic balance level.
[0105] According to some embodiments of the present invention, optionally, the step of detecting dynamic balancing parameters after the motor is assembled specifically includes: controlling the motor to start and rotate at a target speed.
[0106] In this embodiment, in detecting the dynamic balance parameters of the entire motor, the motor is controlled to start and rotate at a target speed through its own electromagnetic drive, and then the dynamic balance parameters of the entire motor are detected at the target speed.
[0107] Optionally, the target speed is set according to actual conditions. The target speed may be the speed of the motor in a working state, or may be other set values. The target speed may be less than the speed in a working state, or may be greater than the speed in a working state.
[0108] According to some embodiments of the present invention, optionally, the target rotational speed includes the rotational speed of the motor when it is in a working state.
[0109] In this embodiment, the target speed includes the speed when the motor is in a working state, that is, the dynamic balance of the motor is tested when the motor is in a working state, 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 eliminated; 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 at high speed is greater, which can improve the signal-to-noise ratio of the test signal.
[0110] 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 used in an electrical device, enables the rotor to reach the use speed under the drive of the motor itself.
[0111] 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 corresponds to 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.
[0112] According to some embodiments of the present invention, optionally, the rotating component includes a rotor, and before the step of detecting the dynamic balancing parameters after the motor is assembled, it also includes: detecting the dynamic balancing parameters of the rotor and obtaining a second detection value; operating the rotor according to the second detection value so that the dynamic balancing parameters of the rotor are less than or equal to the second parameter threshold.
[0113] In this embodiment, the rotating part includes a rotor. Before the dynamic balance test is performed on the entire motor, a dynamic balance test is also performed on the rotor, and the rotor is operated according to a second detection value obtained by the detection, so that the dynamic balance parameter of the rotor is less than or equal to the second parameter threshold value. That is, the rotor is first dynamically balanced, and when the dynamic balance test value does not meet the requirements, the rotor is operated to reduce the imbalance to a certain level, and then the whole motor is assembled, and then the dynamic balance test is performed on the whole motor to achieve high-precision dynamic balance adjustment.
[0114] 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 parameter of the rotor is less than or equal to the second parameter threshold.
[0115] It should be noted that the second parameter threshold is a preset parameter, which may be a dynamic balance level.
[0116] According to some embodiments of the present invention, optionally, operating the balancing processing part specifically includes: performing at least one of cutting, drilling, and gluing on the balancing processing part; operating the rotor specifically includes: performing at least one of cutting, drilling, and gluing on the rotor.
[0117] In this embodiment, the operation on the balancing processing part may specifically be at least one of cutting, drilling, and gluing on the balancing processing part, so as to increase or reduce the weight of the balancing processing part, thereby reducing the dynamic balancing parameter. The operation on the rotor specifically includes at least one of cutting, drilling, and gluing on the rotor, so as to increase or reduce the weight of the rotor, thereby reducing the dynamic balancing parameter of the rotor.

[0119] The dynamic balance adjustment device 500 proposed in the present invention includes a detection unit 502 and an operating unit 504. After the motor is assembled, the detection unit 502 detects the dynamic balance parameters of the motor as a whole. Then, the operating unit 504 operates the balance processing part located outside the motor housing according to the detection result, or operates the balance processing part located inside the motor through the avoidance hole to adjust the dynamic balance of the motor as a whole, so that the dynamic balance parameter of the motor is less than or equal to the first parameter threshold, thereby improving the vibration of the motor. Specifically, when the first detection value is greater than the first parameter threshold, it means that the dynamic balance of the motor does not meet the requirements. At this time, the balance processing part is operated so that the dynamic balance parameter of the motor is reduced to the first parameter threshold to meet the dynamic balance requirements of the motor.

[0137] like Fig.11 As shown, according to one embodiment of the present invention, an electronic device 600 is provided, comprising: a dynamic balance adjustment device 500 as proposed in any one of the above items; and / or a processor 602 and a memory 604, wherein the memory 604 stores a program or instruction that can be run on the processor 602, and when the program or instruction is executed by the processor 602, the steps of the dynamic balance adjustment method of the motor as proposed in any one of the above items are implemented. Therefore, all the beneficial effects of the above dynamic balance device or dynamic balance detection method are obtained, which will not be described in detail here.
[0138] According to an embodiment of the present invention, a readable storage medium is provided, on which a program or instruction is stored, and when the program or instruction is executed by the processor 602, a method for adjusting the dynamic balance of a motor as proposed in any of the above items is executed. Therefore, all the beneficial effects of the dynamic balance detection method are achieved, which will not be described in detail here.
[0139] In a specific application, the motor is subjected to a dynamic balancing test after the end cover 14 is assembled. The test is performed on a dynamic balancing bench, and the motor is electromagnetically driven to increase to a stable speed.
[0140] Optionally, the motor is provided with a component (e.g., a balancing portion 3) that can be processed for balancing on the outside of the end cover 14. The balancing portion 3 can be an independent weight-removing end ring (e.g., a balancing ring 300), or can be combined with a structure such as a pulley 32. The weight-removing component can be made of metal or plastic. The balancing portion 3 can be processed for balancing by weight removal or weight addition. The balancing portion 3 can be present at one end or both ends of the rotating shaft 20.
[0141] According to the embodiments proposed in the present application, the dynamic balance of the motor as a whole is closer to the use state of the motor in the dynamic balance test: the interference of the position deviation of the bearing of the rotor 22 in the end cover 14 on the dynamic balance test is eliminated; the rotor 22 can reach the use speed under the drive of the motor itself, and the imbalance caused by the deformation of the rotor 22 under the action of high-speed centrifugal force can be considered. 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.
[0142] Optionally, the motor integral dynamic balancing can be combined with the conventional rotor 22 dynamic balancing. After the unbalance of the rotor 22 is reduced to a certain level through the conventional rotor 22 dynamic balancing, high-precision dynamic balancing can be achieved through the integral dynamic balancing process. In the rotor 22 dynamic balancing process in the related art, if the motor fails to meet the requirements due to vibration due to dynamic balancing reasons, the motor needs to be disassembled for repair, and the repair cost is high and the qualified rate is low. The integral dynamic balancing proposed in this application can directly adjust the balance of the motor and reduce the repair cost.
[0143] Optionally, the present application also proposes a rotor 22 design scheme that matches the motor assembly dynamic balancing scheme, and the rotor 22 can be secondary processed when the motor is assembled.
[0144] Optionally, the balancing processing portion 3 is not necessarily located on the outside of the motor end cover 14, and the rotor 22 can also be processed by opening a hole in the end cover 14, but the whole machine balancing test needs to be performed after the end cover 14 is assembled.
