Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a motor structure. Background Technology

[0002] In operating equipment, motors are often equipped with controllers. These controllers receive user commands and precisely manage and regulate the electrical energy supplied to the motor based on these commands. As a power source, the motor receives electrical energy from the controller and converts it into mechanical energy, generating torque and speed to drive the load.

[0003] In operating equipment, the motor and controller are often assembled as one unit. Internally, the U-phase copper busbar of the motor stator is electrically connected to the copper busbar of the controller. Externally, the housing of the motor and the housing of the controller are mechanically connected to maintain a stable connection between the two.

[0004] However, in the existing structure, when repairing or disassembling the motor and controller, it is often necessary to first disconnect the mechanical connection between the two to expose the internal structure, and then disconnect the electrical connection between them. This is not only complicated, but also makes it easy for the two to move relative to each other after the mechanical connection is disconnected, which can lead to damage to the electrical connection.

[0005] Therefore, there is an urgent need for a motor structure to solve the above-mentioned technical problems. Utility Model Content

[0012] A sealing cap, which is detachably connected to the support cap, is used to seal the clearance hole.

[0013] As a preferred technical solution for the above-mentioned motor structure, the U-phase copper busbar is electrically connected to the controller via threaded fasteners.

[0014] As a preferred technical solution of the above-mentioned motor structure, the support cover includes an inner ring, an outer ring, and connecting ribs. The outer ring is connected to the housing. The inner ring is sleeved on the outside of the rotating shaft. The rotating shaft is installed on the rotor. Multiple connecting ribs are provided.

The multiple first connecting ears are evenly distributed around the axis of the outer ring. The circumferential edge of the housing is provided with a second connecting ear, and multiple second connecting ears are provided in one-to-one correspondence with the first connecting ears. The first connecting ears and the second connecting ears are connected by threaded fasteners.

[0016] As a preferred technical solution of the above-mentioned motor structure, the inner ring is provided with a positioning groove on the side opposite to the housing. Multiple positioning grooves are provided and are evenly distributed around the axis of the inner ring. The inner ring of the sealing cover is provided with a third connecting ear, which is inserted into the positioning groove one by one.

[0017] As a preferred technical solution of the above-mentioned motor structure, the inner edge of the sealing cover is connected to the inner ring by a threaded fastener, and the outer edge of the sealing cover is connected to the outer ring by a threaded fastener.

[0018] As a preferred technical solution of the above-mentioned motor structure, the outer edge of the inner ring portion, the inner edge of the outer ring portion, and the two adjacent connecting ribs together form the above-mentioned clearance hole.

[0019] As a preferred technical solution of the above-mentioned motor structure, the support cover is provided with a plurality of clearance holes, including a first clearance hole and a second clearance hole. A plurality of U-phase copper busbars are provided, including a first U-phase copper busbar and a second U-phase copper busbar.

[0022] The beneficial effects of this utility model are:

[0023] This application provides a motor structure, including a housing, a drive assembly, a support cover, and a sealing cover. The drive assembly includes a stator and a rotor. The stator is fixed within the housing, and the rotor is rotatably mounted within the stator. The stator includes a U-phase copper busbar for electrical connection to a controller. The support cover is located axially on the rotor, on the side of the housing opposite to the controller, and fixed to the housing.

[0024] During normal use, the controller and motor are assembled into a single unit, which is installed in the operating equipment. When the operating equipment malfunctions, the integrity of the assembly can be maintained initially, meaning the controller and motor are not disassembled. On the side of the motor facing away from the controller, the sealing cover and support cover are removed first, opening the clearance hole. This allows the U-phase copper busbar and its connection status with the controller to be observed from the outside of the motor. This helps determine if the fault lies in the connection between the motor and the controller. If not, separation is unnecessary, thus completing the troubleshooting process while maintaining the integrity of the assembly, improving troubleshooting efficiency. If the fault does lie, the controller and motor can then be separated. During disassembly, a tool is inserted through the clearance hole on the outside of the motor to disconnect the U-phase copper busbar from the controller. This simplifies the disassembly process.

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] like Figures 1 to 5 As shown, this application provides a motor structure, including a housing 1, a drive assembly, a support cover 3, and a sealing cover 4. The drive assembly includes a stator and a rotor. The stator is fixed inside the housing 1, and the rotor is rotatably mounted inside the stator. The stator includes a U-phase copper busbar 21 for electrical connection with a controller. The support cover 3 is located axially on the rotor, on the side of the housing 1 opposite to the controller, and is fixed to the housing 1. The support cover 3 has a clearance hole 31 through which the U-phase copper busbar 21 is exposed. The sealing cover 4 is detachably connected to the support cover 3 and is used to close the clearance hole 31.

[0040] During normal use, the controller and motor are assembled into an assembly, which is installed in the operating equipment. When the operating equipment malfunctions, the integrity of the assembly can be maintained initially, meaning the controller and motor are not disassembled. On the side of the motor facing away from the controller, the sealing cover 4 and self-supporting cover 3 are removed first, opening the clearance hole 31. This allows the U-phase copper busbar 21 and its connection status with the controller to be seen from the outside of the motor through the clearance hole 31. This helps determine if the fault lies in the connection between the motor and the controller. If not, separation is unnecessary, thus completing the fault diagnosis while maintaining the integrity of the assembly, improving troubleshooting efficiency. If the fault does lie, the controller and motor can then be separated. During disassembly, a tool is inserted through the clearance hole 31 on the outside of the motor to disconnect the U-phase copper busbar 21 from the controller. This simplifies the disassembly process.

[0041] It should be noted that the copper busbar inside the controller is electrically connected to the U-phase copper busbar 21 of the stator, and the outer shell of the controller is mechanically connected to the housing 1 of the motor through a connector. When disassembling the two, while maintaining the mechanical connection between the controller and the motor, first disconnect the electrical connection between the two through the clearance hole 31, and then disconnect the mechanical connection between the two.

[0042] Optionally, the U-phase copper busbar 21 is electrically connected to the controller via threaded fasteners. For example, the controller's copper busbar is connected to the U-phase copper busbar 21 via threaded fasteners, the axis of which is parallel to the rotor's axis. This facilitates connection between the controller and the motor.

[0043] Optionally, the support cover 3 includes an inner ring 32, an outer ring 33, and a connecting rib 34. The outer ring 33 is connected to the housing 1. The inner ring 32 is sleeved on the outside of the rotating shaft, which is installed on the rotor. Multiple connecting ribs 34 are provided, and the multiple connecting ribs 34 are distributed around the axis of the rotor. The connecting ribs 34 connect the inner ring 32 and the outer ring 33.

[0044] For example, the inner ring 32 and outer ring 33 of the support cover 3 are coaxially arranged, with the outer ring 33 sleeved over the inner ring 32. The inner ring 32 and outer ring 33 are connected by multiple connecting ribs 34. In this way, the support cover 3 forms a hollow structure, which can reduce the amount of material used in its manufacture and thus reduce its weight.

[0045] Optionally, the axial edge of the outer ring 33 is provided with a first connecting ear 331, and multiple first connecting ears 331 are provided. The multiple first connecting ears 331 are evenly distributed around the axis of the outer ring 33. The circumferential edge of the housing 1 is provided with a second connecting ear 11, and multiple second connecting ears 11 are provided in one-to-one correspondence with the first connecting ears 331. The first connecting ears 331 and the second connecting ears 11 are connected by threaded fasteners.

[0046] With this configuration, the outer ring 33 and the housing 1 are connected by threaded fasteners, which facilitates the installation of the two. Multiple connection points are formed between the outer ring 33 and the housing 1 to maintain the stability of the connection between the two. Furthermore, the configuration of the first connecting ear 331 and the second connecting ear 11 can reduce the direct openings on the support cover 3 and the housing 1, which is beneficial to maintaining the structural strength of the two.

[0047] Optionally, the inner ring 32 has a positioning groove 321 on the side opposite to the housing 1. Multiple positioning grooves 321 are provided and are evenly distributed around the axis of the inner ring 32. The inner ring of the sealing cover 4 has a third connecting ear 41 protruding and is inserted into the positioning groove 321 in a one-to-one correspondence.

[0048] With this configuration, when the sealing cover 4 and the support cover 3 are assembled, they are inserted along the axial direction of the rotor. The third connecting ear 41 is inserted into the positioning groove 321 to complete the initial positioning, restricting the relative movement between the sealing cover 4 and the support cover 3. Then, the sealing cover 4 and the support cover 3 are fixed by threaded fasteners.

[0049] Optionally, the inner edge of the sealing cover 4 is connected to the inner ring 32 by a threaded fastener, and the outer edge of the sealing cover 4 is connected to the outer ring 33 by a threaded fastener.

[0050] With this configuration, the sealing cover 4 is connected to the inner ring 32 and the outer ring 33 by threaded fasteners, so as to facilitate the disassembly of the sealing cover 4 and the support cover 3. The sealing cover 4 is fixed to the inner ring 32 and the outer ring 33 respectively, which can fully cover the clearance hole 31 and maintain the sealing of the operating environment of the drive component.

[0051] Optionally, the outer edge of the inner ring 32, the inner edge of the outer ring 33, and the two adjacent connecting ribs 34 form a clearance hole 31. In this way, there is no need to make additional holes in the inner ring 32 and / or the outer ring 33; the hollow structure itself serves as the clearance hole 31.

[0052] Optionally, the support cover 3 is provided with multiple clearance holes 31, including a first clearance hole 31a and a second clearance hole 31b. Multiple U-phase copper busbars 21 are provided, including a first U-phase copper busbar 21a and a second U-phase copper busbar 21b. The first U-phase copper busbar 21a is exposed through the first clearance hole 31a, and the second U-phase copper busbar 21b is exposed through the second clearance hole 31b.

[0053] With this configuration, the first U-phase copper busbar 21a and the second U-phase copper busbar 21b will not interfere with each other during installation or disassembly.

[0054] Optionally, multiple U-phase copper busbars 21 are provided, including a first U-phase copper busbar 21a and a second U-phase copper busbar 21b, which are exposed through the same clearance hole 31.

[0055] This design reduces the number of openings in the support cover 3, thus maintaining its structural strength.

[0056] Optionally, a limiting groove 12 is formed on the inner side wall of the housing 1 along the axis of the rotor, and a limiting member is protruding from the outer side wall of the stator. The limiting member is inserted into the limiting groove 12 along the axial direction of the rotor.

[0057] With this configuration, during the installation of the motor, when the stator is inserted into the housing along the axis, the limiting component and the limiting groove 12 are inserted axially. Through the insertion and limiting of the two, the relative movement direction of the stator and the housing can be regulated.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
