Description

Technical Field

[0001] This utility model relates to the field of motor lamination technology, specifically a durable motor lamination. Background Technology

[0002] Motor laminations are an important component of the stator or rotor core of a motor, typically made of silicon steel sheets. These silicon steel sheets are processed into specific shapes using a stamping process, resulting in motor laminations. These laminations possess good magnetic permeability and low iron loss, effectively improving the efficiency and performance of the motor. The shape and size of the motor laminations are determined by the specific design of the motor, and typically include slots, yokes, and other structural features to accommodate different magnetic field distributions and mechanical strength requirements.

[0003] Existing motor laminations have some problems, such as poor heat dissipation and low positioning accuracy, which affect the stability and service life of the motor. In addition, some laminations have insufficient insulation performance in high humidity environments, which limits their application range. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a durable motor lamination, including a lamination body, a connecting piece fixedly connected to the surface of the lamination body, a heat dissipation fin fixedly connected to the end of the connecting piece away from the lamination body, a positioning groove and a mounting hole on the front side of the lamination body, and an insulating coating on the surfaces of the lamination body, the connecting piece and the heat dissipation fin.

[0005] The above technical solution enhances the heat dissipation capacity of the lamination by fixing a connecting piece to the surface of the lamination body and attaching a heat dissipation fin to one end of the connecting piece. The heat dissipation fin helps to quickly dissipate the heat generated by the lamination body, preventing the motor from overheating. Simultaneously, the positioning grooves and mounting holes on the lamination body improve the positioning accuracy of the stacked laminations and the ease of installation, thereby increasing the assembly efficiency and operational stability of the motor.

[0006] As a further improvement to the above solution, the number of connecting pieces is set to several, and the several connecting pieces are evenly distributed on the surface with respect to the center of the front of the stamping body.

[0007] The above technical solution ensures the balance and stability of the laminations during stacking. This symmetrical distribution helps to evenly distribute stress during motor operation, reducing deformation or damage caused by uneven stress on the laminations, thereby extending the service life of the motor.

[0008] As a further improvement to the above solution, the thickness of the heat dissipation fins is half that of the connecting piece.

[0009] The above technical solution forms an effective heat dissipation gap after lamination, optimizes the heat dissipation effect, improves the thermal efficiency of the motor, helps the motor to operate stably under high load conditions, and reduces performance degradation caused by overheating.

[0010] As a further improvement to the above solution, two positioning grooves are provided, which are evenly distributed on the surface with the center of the front of the stamping body symmetrically. The positioning grooves penetrate the front and rear ends of the stamping body. A number of mounting holes are provided, which are evenly distributed on the surface with the center of the front of the stamping body symmetrically.

[0011] The above technical solution improves the positioning accuracy and ease of installation of stacked laminations by setting two through-hole positioning grooves and several evenly distributed mounting holes on the lamination body. This design not only simplifies the motor assembly process but also enhances the stability of motor operation and reduces the risk of failure caused by lamination displacement.

[0012] As a further improvement to the above solution, the material of the insulating coating is a silicon dioxide coating.

[0013] The above technical solution provides excellent insulation and water resistance by applying a silicon dioxide coating to the surface of the lamination body, connecting plates and heat dissipation fins. This effectively prevents short circuits between laminations, reduces eddy current losses, improves motor efficiency, and enables the motor to operate normally in high humidity environments, thus broadening the range of applications for the motor.

[0014] As a further improvement to the above solution, an extension protrusion is fixedly connected to the front side of the stamping body, and an annular groove is provided at the rear end of the stamping body.

[0015] The above technical solution enhances the positioning accuracy and installation stability of the laminations by fixing an extension ring to the front of the lamination body and creating an annular groove at the rear end. The concentric design of the extension ring and the annular groove makes the laminations more precise during stacking and installation, reducing motor instability caused by inaccurate positioning.

[0016] As a further improvement to the above solution, the extending convex ring is concentric with the stamping body, the extending convex ring is concentric with the annular groove, and the inner diameter of the annular groove is adapted to the extending convex ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention features heat dissipation fins, with the fin thickness designed to be half that of the connecting fins. This allows for effective gaps between adjacent heat dissipation fins after the laminations are stacked, promoting airflow and enhancing heat dissipation. Consequently, it improves the thermal stability and reliability of the motor under long-term operation or high-load conditions, effectively preventing performance degradation or damage caused by overheating. The insulating coating effectively prevents short circuits between fins, reduces eddy current losses, improves motor efficiency, and enables the motor to operate normally in high-humidity environments.

[0019] This invention achieves precise positioning and stable installation of the laminations during the stacking process by setting positioning grooves and mounting holes on the lamination body. The positioning grooves ensure precise alignment of the laminations in the axial direction, while the mounting holes facilitate the connection and fixation of the laminations with other components. This not only improves the efficiency and accuracy of motor assembly but also enhances the stability of motor operation and reduces the risk of failure caused by lamination misalignment or loosening.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-4This embodiment provides a durable motor lamination, comprising a lamination body 1, a connecting piece 2 fixedly connected to the surface of the lamination body 1, and a heat dissipation fin 3 fixedly connected to the end of the connecting piece 2 away from the lamination body 1. A positioning groove 4 and a mounting hole 5 are provided on the front side of the lamination body 1. An insulating coating 6 is provided on the surfaces of the lamination body 1, the connecting piece 2, and the heat dissipation fin 3. The heat generated by the lamination body 1 is quickly transferred to the heat dissipation fin 3 via the connecting piece 2, and then released into the surrounding environment by the heat dissipation fin 3, thus dissipating heat in a timely manner and preventing localized overheating from affecting performance. The thickness of the heat dissipation fin 3 is only half that of the connecting piece 2, allowing a certain gap to be formed between adjacent heat dissipation fins 3 after multiple laminations are stacked, further enhancing airflow and thus better performing heat dissipation. The positioning groove 4 and the extended protruding ring 7 together construct a precise positioning system, ensuring precise axial alignment of the laminations during stacking.

[0028] The number of connecting pieces 2 is set to be several. Several connecting pieces 2 are evenly distributed on the surface of the front of the stamping body 1 symmetrically. Multiple connecting pieces 2 are fixedly connected to the surface of the stamping body 1. These connecting pieces 2 are evenly distributed on the front of the stamping body 1 symmetrically to ensure the symmetry and stability of the structure.

[0029] The thickness of the heat dissipation fin 3 is half that of the connecting piece 2. The end of each connecting piece 2 away from the main body 1 of the stamping is fixedly connected to the heat dissipation fin 3. The thickness of the heat dissipation fin 3 is designed to be half that of the connecting piece 2 so as to form an effective heat dissipation gap after the stamping is stacked.

[0030] There are two positioning grooves 4, which are symmetrically and evenly distributed on the surface of the front of the stamping body 1. The positioning grooves 4 penetrate through the front and rear ends of the stamping body 1. There are several mounting holes 5, which are symmetrically and evenly distributed on the surface of the front of the stamping body 1.

[0031] The insulating coating 6 is made of silicon dioxide. A layer of silicon dioxide insulating coating 6 is coated on the surface of the lamination body 1, the connecting piece 2 and the heat dissipation fin 3 to provide excellent insulation performance and water resistance. The insulating coating 6 can effectively prevent inter-laminar short circuits, reduce eddy current losses, improve motor efficiency, and enable the motor to work normally in high humidity environments.

[0032] An extension protrusion 7 is fixedly connected to the front of the stamping body 1, and an annular groove 8 is provided at the rear end of the stamping body 1.

[0033] The extension ring 7 is concentric with the stamping body 1, and the extension ring 7 is concentric with the annular groove 8. The inner diameter of the annular groove 8 is adapted to the extension ring 7.

[0034] The implementation principle of a durable motor lamination in this embodiment is as follows: The lamination body 1 has multiple connecting pieces 2 on its surface, with heat dissipation fins 3 connected to their ends. During operation, the heat generated by the lamination body 1 is quickly transferred to the heat dissipation fins 3 via the connecting pieces 2, and then released into the surrounding environment by the heat dissipation fins 3, thus dissipating heat promptly and preventing localized overheating from affecting performance. The thickness of the heat dissipation fins 3 is only half that of the connecting pieces 2, allowing for a certain gap to be formed between adjacent heat dissipation fins 3 after multiple laminations are stacked, further enhancing airflow and thus better performing the heat dissipation function. The positioning groove 4 and the extended convex ring 7 together construct a precise positioning system. When laminations are stacked, the positioning groove 4 ensures precise axial alignment of the laminations, while the extended convex ring 7 cooperates with the annular groove 8 to further enhance radial positioning, stabilizing the entire core structure.

[0035] The insulating coating 6 covers the surface of the lamination body 1, connecting piece 2 and heat dissipation fin 3. Its silicon dioxide material gives the lamination excellent insulation performance, prevents short circuits between pieces, reduces eddy current loss and improves motor efficiency. At the same time, the coating has good water resistance, which allows the lamination to work normally in high humidity environment, broadens the application range of the motor and enhances its environmental adaptability.
