Description

Technical Field

[0001] This utility model relates to the field of electric motor core technology, specifically a general-purpose split stator core for electric motors. Background Technology

[0002] In the complex structure of an electric motor, the stator core undoubtedly occupies a core and crucial position. Its performance directly affects the stability, efficiency, and service life of the entire motor. For a long time, the traditional integrated stator core has been widely used in the field of electric motors. However, with the development of the times and the innovation of technology, this core structure has gradually revealed many troublesome drawbacks in practical applications.

[0003] From an adaptability perspective, the current electric motor market is showing a diversified and refined development trend. Different industries and application scenarios have extremely diverse requirements for the specifications and models of electric motors. For example, in industrial production, large mechanical equipment requires electric motors with high power and high torque, corresponding to large stator cores with special magnetic permeability characteristics. In the field of smart homes, small electric motors pursue lightness, energy saving and quietness, and stator cores need to have the characteristics of small size and high precision. Faced with such complex changes in demand, the integrated stator core is difficult to adjust flexibly due to its fixed structure. Once the specifications and models of the electric motor change, it is necessary to redesign and manufacture it in all aspects. This process not only consumes a lot of manpower, material resources and financial resources, causing production costs to rise sharply, but also significantly extends the product research and development and production cycle, seriously affecting the company's response speed to market demand.

[0004] The disadvantages of integrated stator cores are also prominent in the installation and maintenance process. Due to their large size and heavy weight, the installation process requires the assistance of professional lifting equipment and a large amount of manpower. The operation process is cumbersome and poses a high safety risk. Furthermore, in subsequent maintenance and repair work, if a certain part of the core fails, due to the limitations of the overall structure, it is often difficult to accurately locate the specific fault point and repair it efficiently. This not only makes the repair difficult but also causes a long period of equipment downtime, resulting in serious economic losses to production and operation. Utility Model Content

[0005] The purpose of this utility model is to provide a universal split stator core for electric motors, in order to solve the problems mentioned in the background art, such as the lack of flexibility of traditional integrated stator cores when adapting to different specifications and models of electric motors, which leads to increased costs, extended R&D and production cycles, and cumbersome operation, high risks, difficult fault repair, and easy to cause long-term equipment downtime during installation and maintenance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a general-purpose split stator core for an electric motor, comprising a core block, wherein a mating groove is provided on one side surface of the core block and a mating protrusion is provided on the other side outer surface of the core block, a connecting plate is fixedly provided on the upper end surface of the core block, and an insertion groove is provided on the side surface of the core block and an insertion hole is provided inside the core block.

[0007] The upper end of the core block is provided with a rotating ring, and the lower surface of the rotating ring is provided with a connecting groove, and a connecting ring is provided inside the connecting groove. A plug rod is fixedly provided on the lower end face of the connecting ring, and a threaded groove is provided on the lower end face of the rotating ring.

[0008] A winding block is provided on the outer side of the core block, and a plug-in plate is fixedly provided on the side surface of the winding block, and a limit hole is opened on the outer surface of the plug-in plate.

[0009] Preferably, both the docking groove and the docking protrusion are circular, and the inner diameter of the docking groove is the same as the outer diameter of the docking protrusion. Two adjacent core blocks are engaged and installed through two opposing docking grooves and docking protrusions.

[0010] By adopting the above technical solution, a precise and tight interlocking connection can be achieved between adjacent core blocks. This allows for flexible increase or decrease in the number of core blocks according to the different motor specifications and the requirements for core size and shape, enabling the rapid assembly of a suitable stator core basic structure and effectively solving the problem of poor adaptability of traditional integrated cores.

[0011] Preferably, the insertion slots are evenly distributed on the outer surface of the core block, and the insertion slots are penetrated by the insertion holes from top to bottom.

[0012] The above technical solution not only provides a clear positioning and installation location for the winding block, making the installation of the winding block more convenient, but also ensures a stable connection between the winding block and the core block after installation. At the same time, the through-hole also facilitates the installation of subsequent components such as the plug rod, enhancing the stability of the overall structure.

[0013] Preferably, the swivel ring is threadedly connected to the connecting plate via a threaded groove, the plug rods are evenly distributed on the lower surface of the connecting ring, and the plug rods and plug holes are arranged in a one-to-one correspondence, and the plug rods and plug holes are engaged and installed.

[0014] By adopting the above technical solution, the connection between the core blocks is greatly enhanced through the dual action of threaded connection and plug-in engagement. During motor operation, it can effectively resist external forces such as vibration and impact, prevent loosening or displacement between the core blocks, ensure stable operation of the stator core, and extend the service life of the motor.

[0015] Preferably, one end surface of the winding block is in contact with the outer surface of the core block, the plug plate and the plug slot are configured in a one-to-one correspondence, the winding block is installed by engaging the plug plate and the plug slot, and the limiting hole and the plug hole are concentrically configured.

[0016] By adopting the above technical solution, the winding block and the core block are tightly fitted and firmly connected. When the plug rod is inserted into the plug hole and passes through the limiting hole, the connection between the winding block and the core block is further strengthened, which enhances the structural stability of the entire stator core from the side. This ensures that the winding block can work stably during the operation of the motor, thereby improving the performance of the motor.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the universal split stator core of this motor:

[0018] 1. The universal split stator core of this utility model is composed of multiple core blocks. The number and combination of core blocks can be flexibly adjusted by the mating groove opened on one side surface of the core block and the mating protrusion set on the other side. It can be easily adapted to both the high power and large size stator core required by large industrial equipment and the small and exquisite core requirements of smart home. There is no need to redesign the entire core for different specifications of motors, which greatly shortens the research and development cycle and reduces production costs.

[0019] Furthermore, the modular structure makes each part of the core small in size and light in weight. During installation, no large lifting equipment is required, and a single person can easily operate it, greatly simplifying the installation process and reducing safety risks. During maintenance and repair, core blocks with specific faults can be disassembled and replaced. Due to the independent structural design of the core blocks, the fault point can be accurately located, achieving efficient repair, effectively shortening equipment downtime, and reducing production and operational losses.

[0020] 2. The connecting plate fixedly installed on the upper end face of the core block is tightly connected to the rotating ring through a threaded groove. The plug rod fixedly installed on the lower surface of the connecting ring precisely engages with the plug hole inside the core block, ensuring a firm connection between each core block. The winding block engages with the plug groove on the side surface of the core block through the plug plate fixedly installed on its side surface. The limiting hole and the plug hole are concentrically set to further strengthen the overall structure. This stable connection method can effectively prevent components from loosening or shifting even when the motor is running at high speed and facing harsh conditions such as complex vibration and impact, ensuring the stability and reliability of the motor operation and extending the service life of the equipment.

The precise matching dimensions of the two core blocks achieve a tight snap-fit ​​installation. Through this snap-fit ​​method, the number of core blocks 1 can be flexibly increased or decreased according to the actual motor specifications' requirements for the core size and shape. Multiple core blocks 1 are then connected in sequence to quickly assemble a stator core basic structure that meets the requirements, effectively solving the problem that traditional integrated cores are difficult to adapt to motors of different specifications.

[0035] Example 2

[0036] This embodiment discloses, based on embodiment one: a connecting plate 4 is fixedly provided on the upper end face of the core block 1, and a plug-in groove 5 is provided on the side surface of the core block 1, and a plug-in hole 6 is provided inside the core block 1.

[0037] The upper end of the core block 1 is provided with a rotating ring 7, and the lower surface of the rotating ring 7 is provided with a connecting groove 8, and the connecting groove 8 is provided with a connecting ring 9.

[0038] A winding block 12 is provided on the outer side of the core block 1, and a plug-in plate 13 is fixedly provided on the side surface of the winding block 12, and a limit hole 14 is provided on the outer surface of the plug-in plate 13.

[0039] The insertion slots 5 are evenly distributed on the outer surface of the core block 1, and the insertion slots 5 are penetrated by the insertion holes 6 from top to bottom;

[0040] The rotating ring 7 is threadedly connected to the connecting plate 4 through the threaded groove 11. The plug rods 10 are evenly arranged on the lower surface of the connecting ring 9, and the plug rods 10 and the plug holes 6 are arranged in a one-to-one correspondence, and the plug rods 10 and the plug holes 6 are engaged and installed.

[0041] One end of the winding block 12 is attached to the outer surface of the core block 1. The plug plate 13 and the plug slot 5 are set in a one-to-one correspondence. The winding block 12 is installed by the plug plate 13 and the plug slot 5. The limiting hole 14 and the plug hole 6 are set concentrically.
