[0032] Currently, there are two main designs for linear motor rotor cores on the market: integral and segmented-tooth assembly. Integral rotor cores typically require a custom mold for each model, while segmented-tooth assembly rotor cores are constructed by assembling multiple small teeth into a single unit.

[0033] The design of existing linear motor rotor cores is highly dependent on large or complex molds, resulting in high manufacturing costs.

[0034] This application provides a motor mover assembly, see Figure 1 As shown, Figure 1 1 is a schematic structural diagram of an embodiment of a motor mover assembly provided by the present application. The motor mover assembly 1 of this embodiment includes a plurality of mover cores 30 , a plurality of winding coils 40 , a first end tooth 10 and a second end tooth 20 .

[0035] The rotor core 30 is the core component of the motor rotor assembly 1 and is usually made of a mold. The rotor core 30 is made of magnetic conductive materials, including but not limited to silicon steel sheets, ferrite, and pure iron.

[0036] The winding coil 40 is a ring-shaped structure made of wound wire and is commonly used in devices such as motors, inductors, and electric motors. For example, when used in an electric motor, the winding coil 40 is wound around the rotor core 30 to generate current in the motor's magnetic field, thereby generating torque or linear motion.

[0037] The plurality of winding coils 40 correspond to the plurality of mover cores 30 . For example, when there are six winding coils 40 and six mover cores 30 , the six winding coils 40 correspond to the six mover cores 30 one by one.

[0038] Optionally, at least one winding coil 40 is wound around the corresponding mover core 30 . In other embodiments, a plurality of winding coils 40 may be wound around one mover core 30 .

[0039] The first end teeth 10 and the second end teeth 20 refer to structures used to complete the splicing of multiple mover cores 30 in the motor mover assembly 1 .

[0040] Optionally, the first end teeth 10 and the second end teeth 20 are respectively connected to two outer movable cores 30 of the plurality of movable cores 30. At this time, the two outer movable cores 30 cannot be spliced ​​with any additional movable cores 30, that is, the plurality of movable cores 30 are no longer spliced.

[0041] The motor mover assembly 1 of this embodiment includes multiple mover cores 30, multiple winding coils 40, first end teeth 10, and second end teeth 20. The multiple mover cores 30 are spliced ​​in sequence, and the first end teeth 10 and second end teeth 20 are respectively connected to two outer mover cores 30 among the multiple mover cores 30. The multiple winding coils 40 correspond to the multiple mover cores 30, and at least one winding coil 40 is wound around a corresponding mover core 30. This approach can reduce reliance on large or complex molds, thereby reducing manufacturing costs.

[0042] In this application, the multiple mover cores 30 in the motor mover assembly 1 have the same structure and can therefore be manufactured using the same mold. In this case, when constructing motor mover assemblies 1 having different numbers of mover cores 30, the mold for each mover core 30 can be the same, allowing the development of the motor mover assembly 1 to be completed with fewer molds. In other embodiments, the multiple mover cores 30 in the motor mover assembly 1 may have different structures.

[0043] According to some embodiments of this application, see Figure 1-Figure 2 As shown, Figure 2 yes Figure 1 Schematic diagram of the structure of an embodiment of a movable core. In this embodiment, each movable core 30 includes a connecting portion 31 and a winding portion 32 connected to the connecting portion 31. A first connecting end 311 and a second connecting end 312 are provided on both sides of the connecting portion 31. The first connecting end 311 of one movable core 30 of two adjacent movable cores 30 is clamped to the second connecting end 312 of the other movable core 30. The winding portion 32 is configured to be provided with a corresponding winding coil 40.

[0044] Optionally, the first connection end 311 of one of the two adjacent movable cores 30 is connected to the second connection end 312 of the other movable core 30 by a clamping member. This means that the first connection end 311 of one of the two adjacent movable cores 30 is provided with a clamping member, and the second connection end 312 of the other of the two adjacent movable cores 30 is provided with a slot, and the clamping member and the slot are configured to achieve the clamping connection. In other embodiments, the first connection end 311 of one of the two adjacent movable cores 30 can be connected to the second connection end 312 of the other of the two adjacent movable cores 30 by other means.

[0045] Optionally, the connecting portion 31 is arranged at the upper end of the movable core 30 , and a first connecting end 311 and a second connecting end 312 are provided on both sides of each connecting portion 31 , that is, the first connecting end 311 and the second connecting end 312 are arranged on both sides of the upper end of the movable core 30 .

[0046] In this embodiment, the first connection end 311 of the movable core 30 is a trapezoidal clamping piece, and the second connection end 312 of the movable core 30 is a trapezoidal clamping groove. Figure 2 As shown, the first connecting end 311 of one of the two adjacent movable cores 30 is clamped with the second connecting end 312 of the other movable core 30, that is, the trapezoidal clamping piece is clamped with the trapezoidal clamping groove. In this way, multiple movable cores 30 are spliced ​​in sequence.

The first connecting end 311 of one of two adjacent mover cores 30 is clipped to the second connecting end 312 of the other mover core 30. The clip-on design of the first connecting end 311 and the second connecting end 312 allows for rapid splicing of multiple mover cores 30, simplifying the splicing process and reducing splicing time and cost. The clip-on design also enhances the stability of the connection between the mover cores 30, reducing loose connections caused by vibration or external forces, thereby improving the reliability and durability of the motor mover assembly 1.

[0052] Specifically, a plurality of winding posts are arranged at intervals and at the same intervals on the connecting portion 31. At this time, a plurality of winding coils 40 correspond to a plurality of winding posts, and a plurality of winding coils 40 are wound on the corresponding winding posts.

[0056] According to some embodiments of the present application, a second connecting portion (not marked in the figure) is provided on the second end tooth 20, and the second connecting portion is connected to the first connecting end 311 of the movable core 30 to connect the second end tooth 20 to the movable core 30 located on the outside.

[0057] Optionally, the second connecting portion is a structure on the second end tooth 20 connected to the first connecting end 311 of the mover core 30 , and the second connecting portion is provided at an upper end of the second end tooth 20 .

[0058] Optionally, a second connecting end 312 is provided on the second connecting portion, so that the second connecting portion is connected to the first connecting end 311 of the mover core 30 located on the outside.

[0059] In this embodiment, the first connecting portion of the first end teeth 10 and the second connecting portion of the second end teeth 20 are respectively connected to the two outer movable cores 30 to form a stable structural frame, thereby improving the mechanical stability and vibration resistance of the motor movable assembly 1.

[0060] According to some embodiments of the present application, the mover core 30 further includes an insulating member 33 , the insulating member 33 is disposed on the winding column, and the winding coil 40 is wound on the corresponding insulating member 33 .

[0061] The insulator 33 is a structure used to separate the winding coil 40 from the winding column in the motor rotor assembly 1. The main function of the insulator 33 is to provide electrical insulation for the winding coil 40, prevent current leakage or short circuit, and ensure safe operation of the motor.

[0062] Optionally, the insulating member 33 is configured in an I-shape and is sleeved on the winding column, as shown in FIG. Figure 2 As shown, the insulating member 33 is provided in plurality and corresponds to the plurality of winding posts.

[0063] In this embodiment, the plurality of winding coils 40 correspond to the plurality of winding posts, that is, the plurality of winding coils 40 correspond to the plurality of insulating members 33 , and the winding coils 40 are wound on the insulating members 33 .

[0064] According to some embodiments of the present application, the movable core 30 also includes a plurality of first limiting members 34, and each winding column is provided with at least one first limiting groove (not marked in the figure) at one end away from the connecting portion 31. The first limiting member 34 is arranged in the first limiting groove of two adjacent winding columns to limit the winding coil 40.

[0065] The first limiting member 34 is a member for limiting the position of the winding coil 40. Optionally, the first limiting member 34 is a slot wedge.

[0066] The first limiting groove refers to a groove or a notch, which is used to cooperate with the first limiting member 34 to limit the winding coil 40.

[0067] The first limiting groove is provided at one end of the winding column away from the connection portion 31 of the mover core 30 . Each winding column is provided with at least one first limiting groove to ensure that it can cooperate with the first limiting member 34 .

[0068] Optionally, each winding column is provided with a first limiting groove on both sides of one end away from the connecting portion 31, as shown in FIG.

[0069] In this embodiment, the number of the first limiting members 34 is reasonably configured according to the number of winding columns in the motor mover assembly 1. For example, see Figure 1 As shown, there are 6 winding columns in the motor mover assembly 1, and the number of the first limiting members 34 is configured to be 5.

[0070] In this embodiment, by setting a first limiting member 34 and a first limiting groove, the first limiting member 34 is set in the first limiting groove of two adjacent winding columns, which can effectively maintain the position and shape of the winding coil 40 on the winding column, avoiding displacement and deformation of the winding coil 40 during the operation of the motor, thereby ensuring the normal operation of the motor and improving the operating stability and reliability of the motor.

[0071] According to some embodiments of this application, see Figure 1-Figure 3 As shown, Figure 3 yes Figure 1 Schematic diagram of the structure of an embodiment of the second limiting member. The mover core 30 of this embodiment also includes a second limiting member 35. Each connecting portion 31 is provided with at least one second limiting groove (not shown) on a side away from the winding portion 32. The second limiting member 35 is disposed in the second limiting groove to limit the position of the motor mover assembly 1 during glue pouring.

[0072] Glue potting is a crucial step in the later stages of the motor rotor assembly 1 manufacturing process. It involves injecting a specific adhesive into the gap between the winding coils 40 of the rotor core 30 and the rotor core 30. This serves to protect the motor rotor assembly 1 from environmental influences and improve the motor's stability and reliability. Optional adhesives include, but are not limited to, epoxy resin, polyurethane, or silicone.

[0073] Optionally, the second limiting member 35 is a T-shaped block, and the second limiting groove is a T-shaped groove corresponding to the second limiting member 35. The second limiting member 35 is arranged in the second limiting groove. Figure 1 As shown, it is used to limit the motor mover assembly 1 during glue pouring.

[0074] Optionally, the second limiting groove is provided on a side of the connecting portion 31 of the movable core 30 away from the winding portion 32. The number of second limiting grooves and second limiting members 35 can be appropriately set as needed. For example, each movable core 30 is provided with three second limiting grooves, and correspondingly, three second limiting members 35 are configured.

[0075] See Figure 4-Figure 6 As shown, Figure 4 It is a structural schematic diagram of an embodiment of the first mold provided by the present application; Figure 5 2. It is a structural schematic diagram of an embodiment in which the mover core and the second end teeth are placed in the first mold; Figure 6 This application also provides a device for preparing a motor mover assembly, which is used to prepare the motor mover assembly 1 of the above embodiment, and includes a first mold 50 and a second mold 60 .

[0076] In this embodiment, the first mold 50 is used to place the plurality of movable cores 30, the first end teeth 10 and the second end teeth 20, so as to splice the plurality of movable cores 30, the first end teeth 10 and the second end teeth 20. The second mold 60 is used to place the plurality of movable cores 30, the first end teeth 10 and the second end teeth 20 after splicing, so as to perform glue pouring on the plurality of movable cores 30, the first end teeth 10 and the second end teeth 20.

[0077] Optionally, a mover core 30 and a second end tooth 20 are placed in the first mold 50, and the mover core 30 and the second end tooth 20 are spliced. The method of splicing the first end tooth 10 to the mover core 30 is the same as that of the second end tooth 20, which will not be repeated here.

[0078] Optionally, the second mold 60 includes a glue injection port (not marked in the figure) and a screw (not marked in the figure). After the spliced ​​multiple movable cores 30, the first end teeth 10 and the second end teeth 20 are placed in the second mold 60, the spliced ​​multiple movable cores 30, the first end teeth 10 and the second end teeth 20 are fixed using screws, and glue is injected through the glue injection port.

[0079] In this embodiment, the first mold 50 is used to splice the multiple mover cores 30, the first end teeth 10, and the second end teeth 20. The second mold 60 is used to perform glue pouring on the spliced ​​multiple mover cores 30, the first end teeth 10, and the second end teeth 20. By using the first mold 50 and the second mold 60 for splicing and pouring glue, respectively, the efficiency and precision of splicing and pouring glue for the multiple mover cores 30, the first end teeth 10, and the second end teeth 20 are improved, thereby enhancing the structural stability of the motor mover assembly 1.

[0080] Optionally, the second limiting member 35 is provided with a plurality of limiting holes 351, which are screw holes. After the assembled plurality of mover cores 30, first end teeth 10, and second end teeth 20 are placed into the second mold 60, the screws engage with the limiting holes 351 of the second limiting member 35 to limit the position of the mover core 30, and thus the position of the motor mover assembly 1, thereby maintaining the position of the motor mover assembly 1 during glue pouring.

[0081] By setting the corresponding second limiting member 35 and the second limiting groove, as well as the corresponding screw and limiting hole 351, it is possible to limit the multiple mover cores 30, the first end teeth 10 and the second end teeth 20 during glue pouring, and then limit the motor mover assembly 1, thereby improving the stability and reliability of the motor mover assembly 1.

[0082] The present application also provides a motor, including a linear motor. The motor of this embodiment includes a stator assembly, a support assembly, and the motor mover assembly 1 of the above embodiment. The stator assembly is primarily used to generate a rotating magnetic field to achieve energy conversion, the support assembly is primarily used for mechanical support and magnetic conductivity, and the motor mover assembly 1 is primarily used to achieve mechanical energy output through magnetic field line cutting.

[0083] In summary, in the present application, after multiple mover cores 30 are sequentially spliced ​​together, the first end teeth 10 and the second end teeth 20 are used to connect two outer mover cores 30 of the multiple mover cores 30, and the winding coils 40 are wound around the corresponding mover cores 30 to form the motor mover assembly 1. By using a method of sequentially splicing multiple mover cores 30, the present application reduces dependence on large or complex molds, thereby reducing manufacturing costs.
