It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.
[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application 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.
[0034] The following describes a motor, a washing device, a dynamic balancing adjustment method, a device, and an electronic device according to some embodiments of the present application with reference to Figures 1 to 11.
[0035] As shown in FIG1 , FIG2 , FIG3 and FIG4 , according to one embodiment of the present application, the present application proposes a motor, including: a housing 1 , a rotating component 2 and a balancing processing part 3 .
[0036] 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. By operating the balancing processing part 3, the dynamic balance parameters of the motor can be adjusted. Specifically, 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.
[0037] The motor provided in the present application includes a casing 1, a rotating part 2 and a balancing processing part 3, a part of the rotating part 2 is arranged in the casing 1, and the casing 1 can protect the rotating part 2 to prevent external structures or dust from affecting the operation of the rotating part 2. Both ends of the rotating part 2 extend out of the casing 1 to achieve the output of power of the rotating part 2. The balancing processing part 3 is arranged on the rotating part 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 motor as a whole 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 motor as a whole. If a product with unqualified dynamic balancing parameters occurs, the motor does not need to be disassembled for repair, thereby reducing manufacturing costs. 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 arranged corresponding to the balancing processing part 3. Then, after the motor is assembled, the dynamic balance test of the entire motor is performed, 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.
[0038] The motor proposed in this application is provided with a balancing processing part 3 outside the casing 1 or a balancing processing part 3 inside the casing 1 and a avoidance hole 10 on the casing 1 that can operate the balancing processing part 3, so that the dynamic balance parameters of the motor as a whole can be adjusted after the motor is assembled, so that the dynamic balance parameters of the motor as a whole meet the requirements, and the vibration of the motor is improved. In addition, when a defective product with unqualified dynamic balance occurs, it is not necessary to disassemble the machine for repair. The balancing processing part 3 outside the casing 1 or the balancing processing part 3 inside the casing 1 can be operated directly 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 operating speed, and the dynamic balance of the motor under normal working conditions can be evaluated, effectively improving the vibration problem of the motor.
[0039] It should be noted that operating the balancing portion 3 includes adding weight to or reducing weight of the balancing portion 3 .
[0040] Illustratively, in some embodiments, the operation performed on the balancing processing portion 3 includes performing at least one of cutting, drilling, and gluing on the balancing processing portion 3 .
[0041] As shown in Figures 2, 3 and 4, according to some embodiments of the present application, exemplarily, in some embodiments, the casing 1 includes: an outer shell 12, 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.
[0042] 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.
[0043] For example, in some embodiments, the avoidance hole 10 is provided on at least one of the two end covers 14 at both ends of the housing 12 .
[0044] As shown in Figure 3, according to some embodiments of the present application, for example, in some embodiments, the rotating component 2 includes: a rotating shaft 20, a portion of the rotating shaft 20 is arranged 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, arranged 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 arranged at at least one of the two ends of the rotating shaft 20; when the balancing processing part 3 is arranged in the outer shell 12, the balancing processing part 3 is arranged on the rotor 22.
[0045] 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. The two 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. Among them, in the case where the balancing processing part 3 is arranged on the outside of the housing 12, the balancing processing part 3 is arranged at at least 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.
[0046] According to some embodiments of the present application, for example, in some implementations, when the balancing portion 3 is provided on the rotor 22 , the balancing portion 3 is a part of the rotor 22 .
[0047] In this embodiment, when the balancing processing portion 3 is provided 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.
[0048] It can be understood that the balancing processing part 3 is a part of the rotor 22. After the dynamic balancing test of the entire motor is performed, 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 entire motor.
[0049] Of course, the balancing portion 3 may also be a separate component provided on the rotor 22 .
[0050] As shown in FIG. 6 and FIG. 7 , according to some embodiments of the present application, exemplarily, in some implementations, the balancing processing portion 3 includes a balancing block 30 .
[0051] 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).
[0052] As shown in FIG8 , according to some embodiments of the present application, illustratively, in some implementations, the balancing weight 30 includes a balancing ring 300 , and the balancing ring 300 is disposed around the outside of the rotating shaft 20 .
[0053] In this embodiment, the gimbal 300 is annularly disposed around the outer side of the rotating shaft 20, improving the balance of the rotating shaft 20 and preventing the rotating shaft 20 from tilting due to the gimbal 300. This also helps improve the reliability of dynamic balancing when adding or removing weight from the gimbal 300.
[0054] As shown in FIG. 5 , FIG. 6 , FIG. 7 and FIG. 8 , according to some embodiments of the present application, exemplarily, in some implementations, the balancing processing portion 3 includes a pulley 32 , and the pulley 32 is provided on the rotating shaft 20 .
[0055] In this embodiment, the balancing unit 3 includes a pulley 32, which is mounted on the rotating shaft 20. Rotation of the rotating shaft 20 drives the pulley 32, thereby enabling 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 achieve power transmission and can also achieve dynamic balance adjustment, saving space occupied by the balancing unit 3 and facilitating a compact design.
[0056] It is understandable that when the motor is used in an electrical device, the motor can be connected to other structures via the pulley 32 to drive the other structures.
[0057] For example, in some embodiments, 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.
[0058] For example, in some embodiments, as shown in FIG8 , a pulley 32 is provided at one end of the rotating shaft 20 , and a balance ring 300 is provided at the other end.
[0059] According to some embodiments of the present application, exemplarily, in some implementation methods, when the balancing processing portion 3 is located outside the housing 1 , the balancing processing portion 3 and the rotating component 2 are an integrated structure.
[0060] 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.
[0061] It is understandable that the balancing portion 3 can be connected to the rotating component 2 by welding or by adhesive bonding.
[0062] According to some embodiments of the present application, illustratively, in some implementations, the balancing processing portion 3 includes a metal processing portion or a plastic processing portion.
[0063] 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 to facilitate weighting or deweighting of the balancing processing part 3. 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.
[0064] According to one embodiment of the present application, a washing device is also proposed, including: a motor as proposed in any of the above embodiments.
[0065] The washing device provided in the present application includes the motor proposed in any of the above embodiments and therefore has all the beneficial effects of the motor.
[0066] For example, in some embodiments, the washing device includes any one of a washing machine and a washer-dryer, and can be a pulsator washing machine or a drum washing machine.
[0067] According to an embodiment of the present application, a method for adjusting the dynamic balance of a motor is also proposed, which is used for any motor proposed above.
[0068] As shown in FIG9 , a flow chart of a method for adjusting the dynamic balance of a motor is shown:
[0069] Step 402: After the motor is assembled, a dynamic balancing parameter is detected and a first detection value is obtained;
[0070] Step 404 : When the first detection value is greater than the first parameter threshold, operate the balancing processing unit to make the dynamic balance parameter of the motor less than or equal to the first parameter threshold.
[0071] The present application provides a method for adjusting the dynamic balance of a motor. After the motor is assembled, the dynamic balance parameters of the entire motor are tested. Based on the test results, the balancing processing portion located outside the motor housing is operated, or the balancing processing portion located inside the motor is operated through a relief hole to adjust the dynamic balance of the entire motor. This adjusts the dynamic balance of the motor so that the dynamic balance parameters of the motor are less than or equal to a first parameter threshold, thereby improving the vibration of the motor. Specifically, if the first test value is greater than the first parameter threshold, it indicates that the dynamic balance of the motor does not meet the requirements. In this case, the balancing processing portion is operated to reduce the dynamic balance parameters of the motor to the first parameter threshold to meet the dynamic balance requirements of the motor.
[0072] 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 increases or decreases in weight, 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 disassemble 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 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.
[0073] Illustratively, in some embodiments, operating the balancing portion includes performing a weighting or weight reduction process on the balancing portion.
[0074] For example, in some implementations, the first parameter threshold may be set according to actual conditions.
[0075] For example, in some embodiments, the first parameter threshold includes a dynamic balance level.
[0076] According to some embodiments of the present application, illustratively, in some implementations, the step of detecting dynamic balancing parameters after the motor is assembled includes: controlling the motor to start and rotate at a target speed.
[0077] 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.
[0078] For example, in some embodiments, the target speed is set according to actual conditions. The target speed may be the speed of the motor in the working state, or other set values. The target speed may be less than the speed in the working state, or greater than the speed in the working state.
[0079] According to some embodiments of the present application, for example, in some implementations, the target rotational speed includes the rotational speed of the motor when it is in a working state.
[0080] 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 usage 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.
[0081] 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 operating speed under the drive of the motor itself.
[0082] The motor may have one or more speeds in each operating state. For example, when a motor is used in an electrical device, the motor may have multiple operating states corresponding to the electrical device because the device has multiple modes. This means that the motor has different speeds in different operating states, and the target speed may be at least one of the speeds in the different operating states.
[0083] According to some embodiments of the present application, for example, in some implementations, the rotating component 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.
[0084] In this embodiment, the rotating component includes a rotor. Before performing a dynamic balance test on the entire motor, a dynamic balance test is also performed on the rotor, and based on a second detection value obtained during the test, the rotor is operated so that the dynamic balance 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 balance detection value does not meet the requirements, the rotor is operated to reduce its imbalance to a certain level, and then the entire motor is assembled and then the dynamic balance test is performed on the entire motor to achieve high-precision dynamic balance adjustment.
[0085] 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.
[0086] It should be noted that the second parameter threshold is a preset parameter, which may be a dynamic balance level.
[0087] According to some embodiments of the present application, for example, in some implementations, operating the balancing processing part includes: performing at least one of cutting, drilling, and gluing on the balancing processing part; operating the rotor includes: performing at least one of cutting, drilling, and gluing on the rotor.
[0088] In this embodiment, operating the balancing portion may specifically include performing at least one of cutting, drilling, and gluing on the balancing portion to increase or decrease the weight of the balancing portion, thereby reducing the dynamic balancing parameters. Operating the rotor includes performing at least one of cutting, drilling, and gluing on the rotor to increase or decrease the weight of the rotor, thereby reducing the dynamic balancing parameters of the rotor.
[0089] As shown in Figure 10, according to one embodiment of the present application, a dynamic balance adjustment device 500 for a motor is provided, including a detection unit 502 for detecting dynamic balance parameters and obtaining a first detection value after the motor is assembled; and an operating unit 504 for operating the balancing processing part so that the dynamic balance 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.
[0090] The dynamic balancing adjustment device 500 proposed in this application includes a detection unit 502 and an operating unit 504. After the motor is assembled, the detection unit 502 detects the dynamic balancing parameters of the motor as a whole. Then, based on the detection results, the operating unit 504 operates the balancing processing part located outside the motor housing, or operates the balancing 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 balancing parameters of the motor are 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 balancing processing part is operated to reduce the dynamic balancing parameters of the motor to the first parameter threshold to meet the dynamic balancing requirements of the motor.
[0091] 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 increases or decreases in weight, 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 disassemble 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 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.
[0092] Illustratively, in some embodiments, operating the balancing portion includes performing a weighting or weight reduction process on the balancing portion.
[0093] For example, in some implementations, the first parameter threshold may be set according to actual conditions.
[0094] For example, in some embodiments, the first parameter threshold includes a dynamic balance level.
[0095] According to some embodiments of the present application, for example, in some implementations, the step of detecting the dynamic balancing parameters by the detection unit 502 after the motor is assembled includes: controlling the motor to start and rotate at a target speed.
[0096] 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.
[0097] For example, in some embodiments, the target speed is set according to actual conditions. The target speed may be the speed of the motor in the working state, or other set values. The target speed may be less than the speed in the working state, or greater than the speed in the working state.
[0098] According to some embodiments of the present application, for example, in some implementations, the target rotational speed includes the rotational speed of the motor when it is in a working state.
[0099] 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 usage 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.
[0100] 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 operating speed under the drive of the motor itself.
[0101] The motor may have one or more speeds in each operating state. For example, when a motor is used in an electrical device, the motor may have multiple operating states corresponding to the electrical device because the device has multiple modes. This means that the motor has different speeds in different operating states, and the target speed may be at least one of the speeds in the different operating states.
[0102] According to some embodiments of the present application, for example, in some implementations, the rotating component includes a rotor, and before the step of detecting the dynamic balancing parameters after the motor is assembled, the detection unit 502 is further used to: detect the dynamic balancing parameters of the rotor and obtain a second detection value; the operation unit 504 is further used to: operate 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.
[0103] In this embodiment, the rotating component includes a rotor. Before performing a dynamic balance test on the entire motor, a dynamic balance test is also performed on the rotor, and based on a second detection value obtained during the test, the rotor is operated so that the dynamic balance 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 balance detection value does not meet the requirements, the rotor is operated to reduce its imbalance to a certain level, and then the entire motor is assembled and then the dynamic balance test is performed on the entire motor to achieve high-precision dynamic balance adjustment.
[0104] 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.
[0105] It should be noted that the second parameter threshold is a preset parameter, which may be a dynamic balance level.
[0106] According to some embodiments of the present application, for example, in some implementations, the operating unit 504 operates the balancing processing part including: performing at least one of cutting, drilling, and gluing on the balancing processing part; the operating unit 504 operates the rotor including: performing at least one of cutting, drilling, and gluing on the rotor.
[0107] In this embodiment, operating the balancing portion may specifically include performing at least one of cutting, drilling, and gluing on the balancing portion to increase or decrease the weight of the balancing portion, thereby reducing the dynamic balancing parameters. Operating the rotor includes performing at least one of cutting, drilling, and gluing on the rotor to increase or decrease the weight of the rotor, thereby reducing the dynamic balancing parameters of the rotor.
[0108] As shown in FIG11 , according to one embodiment of the present application, an electronic device 600 is provided, comprising: a motor dynamic balancing adjustment device 500 as described above; and / or a processor 602 and a memory 604. The memory 604 stores a program or instruction executable by the processor 602, which, when executed by the processor 602, implements the steps of the motor dynamic balancing adjustment method as described above. Therefore, the electronic device 600 has all the advantages of the motor dynamic balancing adjustment device 500 or the motor dynamic balancing adjustment method described above, and no further details are given here.
[0109] According to one embodiment of the present application, a readable storage medium is provided, on which a program or instruction is stored. When executed by a processor 602, the program or instruction performs any of the above-mentioned methods for adjusting the dynamic balance of a motor. Therefore, all the beneficial effects of the dynamic balance adjustment method are achieved, and no further description is given here.
[0110] In a specific application, the motor is subjected to a dynamic balance test after the end cover 14 is assembled. The test is performed on a dynamic balance bench, and the motor is electromagnetically driven to increase to a stable speed.
[0111] For example, in some embodiments, the motor is provided with a component capable of balancing (e.g., balancing portion 3) on the exterior of the end cap 14. Balancing portion 3 can be a standalone weight-reducing end ring (e.g., balancing ring 300) or integrated with a structure such as a pulley 32. The weight-reducing component can be made of metal or plastic. Balancing portion 3 can be achieved by either weight removal or weight addition. Balancing portion 3 can be located at one or both ends of the rotating shaft 20.
[0112] According to the embodiments proposed in the present application, the dynamic balance of the entire motor is closer to the usage 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 operating 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.
[0113] For example, in some embodiments, motor integral dynamic balancing can be combined with conventional rotor 22 dynamic balancing. After reducing the rotor 22 imbalance to a certain level through conventional rotor 22 dynamic balancing, high-precision dynamic balancing can be achieved through integral dynamic balancing. In the related art rotor 22 dynamic balancing process, if the motor fails to meet the required vibration standards due to dynamic balancing issues, the motor must be disassembled and repaired, resulting in high repair costs and low pass rates. The integral dynamic balancing proposed in this application, however, can directly adjust the motor balance, reducing repair costs.
[0114] For example, in some embodiments, the present application also proposes a rotor 22 design scheme that is compatible with the motor assembly dynamic balancing scheme, and the rotor 22 can be processed secondary when the motor is assembled.
[0115] For example, in some embodiments, 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 motor balancing test needs to be performed after the end cover 14 is assembled.
