[0002] As motors and related equipment develop towards high performance and high speed, the performance requirements for rotor laminations are increasing. Traditional rotor lamination structures may have problems such as poor heat dissipation, inconvenient installation and disassembly, and poor sealing performance under high-speed rotation, making it difficult to meet the needs of some high-precision, high-power equipment that requires stable operation for a long time. Therefore, it is necessary to develop this new high-speed rotating rotor lamination structure to better adapt to the operating conditions of modern motors and other equipment.

[0003] In previous rotor lamination designs, the ventilation structure was relatively simple, failing to achieve efficient heat dissipation and affecting the stability and service life of the rotor at high speeds. At the same time, the fixing method was not convenient and flexible enough, making equipment maintenance and component replacement time-consuming and labor-intensive. There may also be weak points in the sealing, which can easily allow dust and impurities to enter, affecting internal electrical performance. The current trend of technological development is to optimize these shortcomings and comprehensively improve the performance of rotor laminations in all aspects. This high-speed rotating rotor lamination was developed in response to this trend of continuous technological improvement. It addresses the problems existing in the above-mentioned traditional technologies through unique designs such as arc-shaped blocks, triangular holes, fixing components, and sealing structures.

[0004] In view of this, we have studied and improved the existing structure and its shortcomings, and provided a high-speed rotating rotor lamination in order to achieve a more practical purpose. Utility Model Content

[0029] Structural Description: Ring-shaped plate 1

[0030] Structural Support and Force Transmission: When the rotor laminations rotate at high speed, the annular lamination, as the outer contour structure of the whole, bears the main structural support role. It withstands the centrifugal force and other external forces generated by high-speed rotation and evenly distributes these forces to the connected components, such as the internally abutting arc-shaped block 2, ensuring the integrity and stability of the entire rotor lamination structure under high-speed rotation. This allows it to rotate stably around the center without easily causing structural deformation or other problems, providing a foundation for the sealing structure: the annular groove 6 at its outer bottom provides space for the installation of the sealing ring 7, which is an important foundation for building the sealing system. By cooperating with the sealing ring 7, it prevents external impurities from entering the rotor lamination from the outside during high-speed rotor rotation, maintaining a relatively clean internal working environment and ensuring that the normal operation of each component is not disturbed by external factors.

[0031] 2. Arc-shaped block 2

[0032] Connection and Force Transmission: One end of the arc-shaped block 2 is fixedly connected to the inside of the annular plate 1, and the other end is connected to the central plate 3, acting as a bridge connecting these two key components. When the rotor rotates at high speed, it transmits the force borne by the annular plate 1 to the central plate 3, ensuring a reasonable distribution of force throughout the rotor lamination and collaboratively maintaining structural stability. Simultaneously, the arc-shaped external shape helps optimize the force transmission path, better adapting to the mechanical environment during high-speed rotation and reducing stress concentration. Ventilation and Heat Dissipation Assistance: The ventilation holes between the arc-shaped block 2 and the central plate 3 guide airflow during the high-speed rotation of the rotor lamination. When the rotor rotates, external cool air can enter the rotor lamination through these ventilation holes, exchange heat with the internal heat-generating components, remove heat, and then be discharged through other ventilation channels. This effectively assists the entire rotor lamination in achieving heat dissipation, ensuring stable operation within a suitable temperature range.

[0033] 3. Central Piece 3

[0034] Stable center and balanced force: Located at the center of the rotor lamination, it is the key to the balanced force of the entire structure. When rotating at high speed, it receives the force transmitted from the arc block 2 and distributes it evenly in all directions, ensuring that the entire rotor lamination rotates smoothly around its center. This avoids abnormal situations such as eccentricity and vibration caused by uneven force, and maintains the stability and accuracy of rotation. Core role of ventilation and heat dissipation: The three arc-shaped triangular holes 4 arranged in a circle inside serve as the central ventilation port of the lamination. When the rotor rotates at high speed and drives the air flow, these triangular holes become important channels for heat exchange. Cold air can smoothly enter the interior through the triangular holes, fully contact the heat-generating components and take away the heat. Hot air is then discharged through these holes. This is the core component of the entire rotor lamination heat dissipation mechanism and plays a vital role in controlling the operating temperature of the rotor lamination.

[0035] 4. Triangular hole 4

[0036] Airflow Guidance: The specially designed arc-shaped triangular holes, arranged in a circle around the center point of the central plate 3, guide the outside air into the rotor laminations in an orderly manner when the rotor laminations rotate at high speed. This provides a specific path and direction for air entry and facilitates the discharge of internal hot air in a certain direction. This allows the air to form an efficient convection circulation within the rotor laminations, thereby enhancing the heat dissipation effect and ensuring that the rotor laminations do not experience performance degradation or component damage due to heat accumulation. Key Heat Dissipation Channel: This is a key ventilation port in the entire heat dissipation system. During heat exchange, it allows cool air to fully contact the heat source inside the rotor laminations, achieving rapid heat transfer. Then, the hot air is discharged to the external environment through the triangular holes, maintaining the internal temperature within a suitable range and ensuring the normal operation and long service life of the rotor laminations under high-speed rotation.

[0037] 5. Hollow cylinder

[0038] Installation Positioning and Rotation Support: The hollow cylinder 5 provides a reference position for the installation of the rotor laminations. The rotor laminations are connected to it through a fixing component, enabling them to be accurately installed in the corresponding equipment. During high-speed rotation, the hollow cylinder 5 supports the rotation of the rotor laminations, providing a stable axis of rotation. This ensures that the rotor laminations rotate smoothly and steadily around this axis at high speed, reducing the occurrence of wobbling, eccentricity, and other issues affecting the rotation quality caused by unstable installation. Working in conjunction with the fixing component: The L-shaped groove 10 on its inner wall cooperates with the protrusion 9, which is one of the key structures for facilitating the disassembly and installation of the rotor laminations. During installation, it provides a trajectory guide for the sliding and final fixing of the protrusion 9, ensuring that the rotor laminations can be securely installed on the hollow cylinder 5. During disassembly, it allows the protrusion 9 to smoothly detach along the corresponding path, facilitating maintenance, replacement, and other operations.

[0039] 6. Annular groove 6

[0040] Sealing Ring Reception and Positioning: The main function of the annular groove 6 is to accommodate the sealing ring 7, providing an accurate installation position and fixed space for the sealing ring 7. This allows the sealing ring 7 to perform its sealing function in the appropriate position. By limiting the installation area of ​​the sealing ring 7, it ensures that it will not shift during the high-speed rotation of the rotor lamination, thus guaranteeing the reliability and stability of the seal. Foundation of the Sealing System: As part of the sealing structure, the annular groove 6, together with the sealing ring 7, forms a barrier to prevent external impurities from entering the rotor lamination. When the rotor rotates at high speed, the annular groove 6 and the sealing ring 7 work together to fill any gaps that may exist, preventing dust, moisture, and other impurities from seeping in from the outside, maintaining a good working environment inside the rotor lamination, and ensuring that the performance of each component is not affected by external contamination.

[0041] 7. Sealing ring 7

[0042] Sealing function: Made of rubber, the sealing ring 7 has good elasticity and plasticity. When the rotor lamination rotates at high speed, it relies on its own elastic deformation to tightly fit the annular groove 6 and other contact parts, filling the gaps and forming an effective seal. It can prevent external dust, impurities, moisture and other substances from entering the rotor lamination, avoiding these foreign objects from causing corrosion, wear and other damage to the internal electrical components and mechanical structures, ensuring that all internal components can work normally in a clean and stable environment. Assisted in shock absorption and buffering: In addition to the sealing function, it can also play a certain role in shock absorption and buffering. When the rotor lamination experiences slight vibration or force changes during high-speed rotation, the sealing ring 7 can absorb and buffer these forces through its own elasticity, reducing the transmission of vibration to other parts, further ensuring the stability and reliability of the entire rotor lamination system.

[0043] 8. Rotating ring 8

[0044] Operational Assistance and Force Transmission: The rotating ring 8 is fixedly connected inside the protrusion 9, playing a crucial operational assistance role in the installation and disassembly of the rotor laminations. When it is necessary to install or disassemble the rotor laminations, rotating the rotating ring 8 can drive the protrusion 9 to slide within the L-shaped groove 10 on the inner wall of the hollow cylinder 5, realizing the connection or separation of the rotor laminations and the hollow cylinder 5. At the same time, it also transmits the force applied during operation to a certain extent, making the sliding of the protrusion 9 smoother and more stable, ensuring the convenience and accuracy of the entire installation and disassembly process. Coordinated Fixing and Rotation: When the rotor laminations rotate normally at high speed, the rotating ring 8 and the protrusion 9 work together to ensure that the protrusion 9 is stably positioned in the fixed position of the L-shaped groove 10, maintaining a stable connection between the rotor laminations and the hollow cylinder 5, allowing it to rotate stably around the axis of the hollow cylinder 5 without affecting the rotational performance due to loose connections or other issues.

[0045] 9. Bump 9

[0046] Connection and sliding fit: The protrusions 9 are arranged equidistantly around the circumference, and one end of their outer side is slidably connected to the L-shaped groove 10 on the inner wall of the hollow cylinder 5. They are fixedly connected to the rotating ring 8 inside. During installation, the protrusions 9 slide in along the entrance of the L-shaped groove 10, and then are driven by the rotating ring 8 to slide to a fixed position in the L-shaped groove 10, realizing a reliable connection between the rotor lamination and the hollow cylinder 5. This ensures that the rotor lamination will not detach from the installation position when rotating at high speed. When disassembling, the operation is reversed, and the protrusions slide out along the L-shaped groove 10 to complete the disassembly operation. This is one of the core components that realizes the function of convenient disassembly and installation. Force transmission and distribution: During the high-speed rotation of the rotor lamination, the protrusions 9 not only bear the force transmitted from the rotating ring 8, but also reasonably distribute these forces to the hollow cylinder 5, ensuring the uniform distribution of force in the entire fixed connection structure, avoiding excessive local force that could lead to component damage, and maintaining the structural stability and connection reliability of the rotor lamination during high-speed rotation.

[0047] 10. L-shaped groove 10

[0048] Sliding guidance and positioning: The L-shaped groove 10 is opened on the inner wall of the hollow cylinder 5. Its unique L-shaped structure provides precise guidance for the sliding of the protrusion 9. During installation, the guide protrusion 9 slides in from the inlet and is rotated to slide along the horizontal section to the final fixed position. This limits the sliding trajectory and fixed position of the protrusion 9, ensuring that the rotor lamination can be accurately and stably installed on the hollow cylinder 5. During disassembly, it provides a corresponding path for the protrusion 9 to come out, making the disassembly process smooth. Connection stability assurance: By standardizing and positioning the sliding of the protrusion 9, the stability of the connection between the rotor lamination and the hollow cylinder 5 is ensured. During the high-speed rotation of the rotor lamination, the protrusion 9 will not move arbitrarily, maintaining a stable connection between the rotor lamination and the hollow cylinder 5. This ensures that the entire rotor lamination can rotate smoothly and reliably at high speed around the axis of the hollow cylinder 5, playing an important structural support role for the normal operation of the entire rotor lamination.

[0049] Working Principle: When the rotor laminations rotate at high speed, the annular lamination 1, as the external support structure of the whole, bears the main centrifugal force. Multiple arc-shaped blocks 2, fixedly connected inside, form a stable overall structure together with the annular lamination. Furthermore, the arc-shaped blocks 2 transmit the force to the central lamination 3, achieving a uniform distribution of force across the entire rotor lamination and ensuring stability during high-speed rotation. The hollow cylinder 5 provides mounting support points for the rotor laminations and is connected to the annular lamination 1 through fixing components, allowing the rotor laminations to rotate stably at high speed around the axis of the hollow cylinder 5. Three circumferentially arranged arc-shaped triangular holes 4 inside the central lamination 3 serve as ventilation openings. When the rotor laminations rotate at high speed, air can flow through these holes to create convection, carrying away the heat generated during operation and preventing overheating from affecting the performance and service life of the rotor laminations. The arc-shaped blocks 2 and... Ventilation holes are provided between the central plates 3, further increasing the airflow channels and improving heat dissipation efficiency. This ensures that the rotor laminations can dissipate heat in time during high-speed rotation, maintaining normal operating temperature. A rubber sealing ring 7 is fixedly connected to the annular groove 6 at the bottom of the annular plate 1. During high-speed rotation of the rotor laminations, this effectively seals the gaps between the rotor laminations and other components, preventing dust and impurities from entering and affecting rotation. It also provides some shock absorption. The protrusion 9 in the fixing assembly is connected externally to a rotating ring 8 and slidably to an L-shaped groove 10 on the inner wall of the hollow cylinder 5. This allows for convenient disassembly and installation of the rotor laminations on the hollow cylinder 5. During installation, the protrusion 9 is aligned with the entrance of the L-shaped groove 10 and slid in. Then, the rotating ring 8 is rotated to slide the protrusion 9 into a fixed position within the L-shaped groove 10, thus achieving fixation. Disassembly is performed in reverse.
