Abstract
Description
Technical Field
[0001] This utility model relates to the field of stator and rotor technology, specifically a split stator and rotor structure. Background Technology
[0002] In traditional stator-rotor motor structures, the stator and rotor are typically connected by fixed welding or casting methods, resulting in a complex overall structure that is difficult to disassemble. When this traditional motor structure malfunctions or requires maintenance, the entire motor often needs to be disassembled, and the stator and rotor dimensions and configurations cannot be quickly adjusted to specific needs. Furthermore, the stator and rotor are often designed as a single unit, failing to consider the need for flexible adjustments under different operating environments, leading to poor adaptability in various application scenarios and making upgrades and improvements difficult.
[0003] Furthermore, the magnetic circuit design in traditional motors typically relies on a simple combination of coils and a stator core, lacking precise control over the electromagnetic field. This leads to losses and fluctuations in the magnetic field lines. Due to the instability of the magnetic field, eddy current losses are prone to occur, thus affecting the motor's output performance and efficiency. Therefore, this paper researches and improves upon existing problems by providing a split stator-rotor structure to address these issues. The aim is to solve the problems and enhance the practical value of the motor through this technology. Utility Model Content
[0004] The present invention aims to solve the technical problems existing in the prior art or related technologies.
[0005] This utility model relates to a split-type stator and rotor structure, and more particularly to a split-type stator and rotor structure that achieves high detachability, customizability, and efficient electromagnetic field control through modular design. The specific implementation is as follows:
[0006] A split-type stator-rotor structure includes: splicing rings, a stator assembly, and a rotor disk. The splicing rings have joint holes on their surface for splicing adjacent rings. The stator assembly includes frequency converters, a fixing plate, and magnetic coils fixed to the surface of the fixing plate. The frequency converters and the fixing plate are arranged alternately and distributed circumferentially around the outer periphery of the splicing rings. The rotor disk is rotatably mounted on the inner side of the splicing rings, and several permanent magnet blocks are embedded in the surface of the rotor disk, with each permanent magnet block evenly distributed circumferentially. This structure, through the joint holes on the splicing rings, allows multiple splicing ring modules to be spliced together and combined into a stator-rotor structure, increasing the structure's disassembly and flexibility, and facilitating later assembly, maintenance, and upgrades.
[0007] In a preferred embodiment, this invention can be further configured such that the output terminal of the frequency converter is electrically connected to the end of the magnetic coil, allowing alternating current to flow into the magnetic coil. By electrically connecting the output terminal of the frequency converter to the magnetic coil, alternating current can be input into the magnetic coil, thereby generating an electromagnetic field, improving the motor's efficiency, and enhancing the magnetic traction force.
[0008] In a preferred embodiment, this invention can be further configured such that: a magnetic yoke block is provided on one side of the fixing plate relative to the splicing ring surface, and a magnetic coil is sleeved on the surface of the magnetic yoke block. Specifically, after an alternating current is applied to the magnetic coil, the magnetic yoke block generates an electromagnetic effect, thereby forming a magnetic traction effect. By setting a magnetic yoke block on the surface of the fixing plate and having the magnetic coil sleeved on its surface, a more stable and efficient magnetic traction effect can be formed, thereby enhancing the output performance and efficiency of the motor.
[0009] In a preferred embodiment, this invention can be further configured such that: the splicing ring is a ring-shaped non-ferromagnetic material component, the thickness of the splicing ring is less than or equal to 1 mm, and the gap between the permanent magnet block and the magnetic coil is less than or equal to 3 mm. Using a non-ferromagnetic material component as the splicing ring and controlling the thickness to within 1 mm effectively reduces unnecessary magnetic losses. Simultaneously, by precisely controlling the gap between the permanent magnet block and the magnetic coil, the efficiency of the magnetic field is optimized, further improving motor performance.
[0010] In a preferred embodiment, this invention can be further configured such that the frequency converter converts the input current into a high-frequency alternating current flowing through the magnetic coil. By converting the input current into a high-frequency alternating current through the frequency converter, the electromagnetic effect requirements within the magnetic coil can be better met, improving the motor's response speed and power output, and enhancing the overall performance of the system.
[0011] In a preferred embodiment, this invention can be further configured such that: the surface of the rotor disk has several coil slots for fixing the rotor windings; the rotor disk is a ferromagnetic material component. By creating coil slots on the surface of the rotor disk and using a ferromagnetic material component to manufacture the rotor disk, the stability of the rotor windings is enhanced, while the electromagnetic field traction is improved, thereby increasing the motor's working efficiency and output capacity.
[0012] The beneficial effects achieved by this utility model are as follows:
[0013] 1. In this utility model, by opening joint holes on the splicing ring, multiple splicing ring modules can be spliced together to form a stator and rotor structure. The stator assembly and rotor disc are detachably connected to the splicing ring, giving the entire motor structure a high degree of detachability and modularity. This facilitates later assembly, maintenance, and upgrades. This design enhances the flexibility and customizability of the motor in practical applications, allowing for quick adjustment of the stator and rotor composition and dimensions according to different usage scenarios.
[0014] 2. In this utility model, the frequency conversion element and the fixing plate are arranged in an alternating manner and distributed circumferentially on the outer periphery of the splicing ring. Current is passed through to generate an electromagnetic field, which can better control the direction of the magnetic field lines, reduce magnetic field fluctuations and eddy current losses, thereby improving the output performance and efficiency of the motor.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0022] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0023] The following is in conjunction with the appendix Figures 1-4 This invention describes a split stator and rotor structure provided by some embodiments of the present invention. Example 1
[0024] A split-type stator and rotor structure includes: a splicing ring 100, a stator assembly 200, and a rotor disk 300. The splicing ring 100 has a joint hole 110 on its surface for splicing between adjacent splicing rings 100. The stator assembly 200 includes a frequency converter 210, a fixing plate 220, and a magnetic coil 230 fixed to the surface of the fixing plate 220. The frequency converter 210 and the fixing plate 220 are arranged alternately and distributed circumferentially on the outer periphery of the splicing ring 100. The rotor disk 300 is rotatably mounted on the inner side of the splicing ring 100, and a plurality of permanent magnet blocks 310 are embedded in the surface of the rotor disk 300. Each permanent magnet block 310 is evenly distributed in the circumferential direction.
[0025] In this embodiment, the splicing ring 100 is a ring-shaped non-ferromagnetic material component, possessing lightweight characteristics. Multiple splicing rings 100 are connected and spliced through splicing holes 110 to form the required stator and rotor structure. This structure not only ensures the modular design of each part but also allows the motor to be flexibly combined as needed. It is suitable for various different motor application scenarios, enabling high-efficiency output and precise control.
[0026] In this embodiment, the output terminal of the frequency converter 210 is electrically connected to the end of the magnetic coil 230, allowing alternating current to flow through the magnetic coil 230. As a drive power source, the frequency converter 210 converts externally input DC current into alternating current and transmits it to the magnetic coil 230. This enables high-frequency alternating current to flow through the magnetic coil 230, thereby generating a stable electromagnetic field. Through the variation and control of the current, a highly efficient magnetic traction effect is formed, driving the rotor disk 300 to rotate and achieving normal operation of the motor.
[0027] In this embodiment, the fixing plate 220 has a magnetic yoke block on one side of the splicing ring 100, and the magnetic coil 230 is sleeved on the surface of the magnetic yoke block. Specifically, after an alternating current is applied to the magnetic coil 230, it generates an electromagnetic effect in conjunction with the magnetic yoke block, thereby forming a magnetic traction effect.
[0028] To improve motor efficiency, a magnetic yoke block is designed on one side of the fixing plate 220, and a magnetic coil 230 is sleeved on its surface. When current passes through the magnetic coil 230, the interaction between the electromagnetic effect and the magnetic yoke block generates a strong magnetic traction force, which can effectively drive the rotor disk 300 to rotate, thereby improving the power output and stability of the motor.
[0029] In this embodiment, the splicing ring 100 is a ring-shaped non-ferromagnetic material component, the thickness of the splicing ring 100 is less than or equal to 1 mm, and the gap between the permanent magnet block 310 and the magnetic coil 230 is less than or equal to 3 mm.
[0030] The splicing ring 100 is made of a non-ferromagnetic material such as aluminum alloy, with a thickness controlled to within 1 mm. This design not only reduces the weight of the structure but also avoids unnecessary magnetic losses, ensuring efficient motor operation. Simultaneously, precisely controlling the gap between the permanent magnet block 310 and the magnetic coil 230 further optimizes the magnetic field effect and improves the motor's output efficiency.
[0031] In this embodiment, the frequency converter 210 is used to convert the input current into a high-frequency alternating current flowing through the magnetic coil 230. The frequency converter 210 is a frequency converter module that converts externally input DC or AC current into a high-frequency AC current. By controlling the frequency and amplitude, it ensures that the magnetic coil 230 receives a suitable AC current input to generate the required electromagnetic force. This design ensures stable operation of the motor under different loads and is particularly suitable for motor applications requiring high-precision control.
[0032] In this embodiment, the rotor disk 300 has several coil slots on its surface for fixing the rotor windings. The rotor disk 300 is a ferromagnetic material component. The rotor disk 300 is made of a ferromagnetic material, such as silicon steel sheet, and has several coil slots on its surface to facilitate the installation of the rotor windings. Placing coil slots on the surface of the rotor disk 300 effectively fixes the rotor windings, ensuring that the windings are not easily dislodged and guaranteeing the stability of the electromagnetic effect. Simultaneously, the use of ferromagnetic material can increase the strength of the magnetic field, thereby enhancing the traction and efficiency of the motor. Example 2
[0033] In another embodiment, the splicing ring 100 still connects multiple modules through the splicing holes 110, but this time the material used is a lightweight composite material. By reducing weight, the mobility and flexibility of the motor are improved, making it suitable for applications requiring frequent disassembly and assembly.
[0034] In this embodiment, the frequency converter 210 is improved into a high-frequency converter that can provide higher frequency alternating current, thereby improving the dynamic response speed of the motor and making it suitable for high-performance precision motor systems.
[0035] Regarding the gap between the fixed plate 220 and the magnetic coil 230, this embodiment adopts an adjustable gap design, so that the electromagnetic force and output efficiency can be optimized by adjusting the gap under different loads.
[0036] Summarize
