[0015] The beneficial effects of the utility model are:

[0016] Compared with the existing linear motors, the use of marble as the base material in this utility model is a highlight of the design. Marble has excellent rigidity and stability, can effectively suppress vibration and deformation, and provide solid and reliable support for the linear motor. Compared with the traditional metal base, the marble base can better maintain the relative position relationship of the motor components, ensuring that the motor can still maintain high precision and stable performance when running at high speed. This stability not only increases the service life of the motor, but also ensures that it can perform at its best under various working conditions.

[0017] Two sets of guide rails are arranged on the marble base of the utility model to form a precise guide rail system. The slider can slide smoothly along the guide rail, which greatly improves the guide accuracy of the mover assembly. This high-precision guide not only ensures the linearity and stability of the motor output torque, but also lays a solid foundation for the positioning and control accuracy of the motor. Compared with the traditional ball screw or chain transmission method, this guide rail guide has higher rigidity and lower friction loss, thereby improving the overall performance of the motor.

[0018] The utility model continuously arranges multiple stator magnets on the marble base to form an optimized magnetic circuit structure. This magnetic circuit design can maximize the use of the stator magnetic field and improve the thrust output and energy conversion efficiency of the motor. At the same time, the opposing design of the mover assembly and the stator magnets also helps to form a more concentrated and stable magnetic field, further improving the thrust performance of the motor. This carefully designed magnetic circuit layout enables the motor to achieve a stronger output capacity under the conditions of smaller volume and weight.

[0019] The marble used as the base material of the utility model has excellent corrosion resistance, high temperature resistance and impact resistance. These characteristics enable the linear motor to operate stably for a long time in harsh industrial environments, greatly improving its scope of application. Compared with the traditional metal base, the marble base is more resistant to chemical corrosion and can better protect the sensitive parts inside the motor from the influence of the external environment. At the same time, the low thermal expansion coefficient of the marble itself also ensures that the motor can maintain high precision when the temperature changes. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figure 1 to Figure 4 As shown, in one embodiment of the utility model, a linear motor with a marble base is involved, including a marble base 1, a guide rail 2, a stator magnet block 3, a mover assembly 4 and a sliding seat 5, wherein the marble base 1 is provided with a sink 11, and the sink 11 runs through the length direction of the marble base 1, and the guide rail 2 is provided with two groups, and the two groups of guide rails 2 are respectively installed on both sides of the sink 11, and the stator magnet block 3 is provided with a plurality of stator magnet blocks 3, and the plurality of stator magnet blocks 3 are continuously arranged along the length direction of the sink 11, and the sliding seat 5 is provided with a slider 51, and the slider 51 can be slidably arranged on the guide rail 2, and one side of the sliding seat 5 is provided with a placement groove 52, and the placement groove 52 is arranged opposite to the sink 11, and the mover assembly 4 is installed in the placement groove 52 and arranged opposite to the stator magnet block 3. The use of marble as the base material in this embodiment is a highlight of the design. Marble has excellent rigidity and stability, can effectively suppress vibration and deformation, and provide solid and reliable support for the linear motor. Compared with the traditional metal base, the marble base 1 can better maintain the relative position relationship of the motor components, ensuring that the motor can still maintain high precision and stable performance when running at high speed. This stability not only increases the service life of the motor, but also ensures that it can perform at its best performance under various working conditions.

[0029] Two sets of guide rails 2 are arranged on the marble base 1 of this embodiment to form a precise guide rail system. The slider 51 can slide smoothly along the guide rail, which greatly improves the guiding accuracy of the mover assembly 4. This high-precision guiding not only ensures the linearity and stability of the motor output torque, but also lays a solid foundation for the positioning and control accuracy of the motor. Compared with the traditional ball screw or chain transmission method, this guide rail type guiding has higher rigidity and lower friction loss, thereby improving the overall performance of the motor.

[0030] In this embodiment, a plurality of stator magnets 3 are continuously arranged on the marble base 1 to form an optimized magnetic circuit structure. This magnetic circuit design can maximize the use of the stator magnetic field and improve the thrust output and energy conversion efficiency of the motor. At the same time, the opposing design of the mover assembly 4 and the stator magnet 3 also helps to form a more concentrated and stable magnetic field, further improving the thrust performance of the motor. This carefully designed magnetic circuit layout enables the motor to achieve a stronger output capacity under smaller volume and weight conditions.

[0031] This embodiment uses marble as the base material, which has excellent corrosion resistance, high temperature resistance and impact resistance. These characteristics enable the linear motor to operate stably for a long time in harsh industrial environments, greatly improving its scope of application. Compared with the traditional metal base, the marble base 1 is more resistant to chemical corrosion and can better protect the sensitive parts inside the motor from the influence of the external environment. At the same time, the low thermal expansion coefficient of marble itself also ensures that the motor can still maintain high precision when the temperature changes.

[0032] The thickness of the marble base 1 is 10-12 mm, and the depth of the sink 11 is 3-6 mm. In this embodiment, a smaller marble base 1 is used, which is suitable for flat transmission, has a stable and reliable structure, and is suitable for large-stroke transmission.

[0033] One side of the guide rail 2 abuts against the groove wall of the sink 11, and one end of the guide rail 2 extends out of the sink 11 to cooperate with the slider 51. The guide rail 2 is provided with a V-shaped groove 21 on the upper side of the groove wall of the sink 11, and the slider 51 is provided with a sliding guide post 511, and one end of the sliding guide post 511 can be slidably set in the V-shaped groove 21. Specifically, a support 211 is provided on one side of the V-shaped groove 21, and the support 211 is used to abut one side of the sliding guide post 511. The slider 51 is installed on the groove wall of the placement groove 52 and is relatively parallel to the top end surface of the guide rail 2. Stoppers 512 are installed at both ends of the slider 51, and the stoppers 512 are used to block the sliding guide post 511 in the slider 51. In this embodiment, the guide rail 2 abuts against the groove wall of the sink 11, and high-precision guidance is achieved through the combination of the V-shaped groove 21 and the sliding guide post 511. The V-shaped groove 21 provides stable guidance and positioning, so that the slider 51 can maintain good parallelism and stability during the sliding process. The cooperation between the sliding guide post 511 and the V-shaped groove 21 ensures the accurate sliding of the slider 51 on the guide rail 2, effectively improving the accuracy and stability of the guide. The support 211 is set as one side of the V-shaped groove 21 to support one side of the sliding guide post 511. This design can ensure that the sliding guide post 511 is reliably supported inside the slider 51 to prevent it from deviating from the correct position. At the same time, blocks 512 are set at both ends of the slider 51 to block the sliding guide post 511 in the slider 51 to prevent it from detaching from the slider 51. This reliable support and blocking mechanism ensures the stable connection between the slider 51 and the guide rail 2, further improving the accuracy and reliability of the guide. The guide rail 2 is located above the wall of the sink 11, so that the slider 51 can slide relatively parallel to the top surface of the guide rail 2. This design ensures that the contact area between the slider 51 and the guide rail 2 during the sliding process is maximized, reduces friction and vibration, and achieves a smooth sliding operation. Smooth sliding not only improves the operating stability of the entire linear motor, but also helps to reduce noise and energy consumption.

[0034] The guide rail 2 and the slider 51 are both made of SKD11 material, and the hardness reaches 56HRC after quenching. In this embodiment, SKD11 is a high-carbon high-chromium alloy tool steel, which can reach an ultra-high hardness of 56HRC after quenching. This extremely high hardness can not only greatly improve the wear resistance of the guide rail 2 and the slider 51, but also ensure that they maintain excellent surface finish and precision during long-term high-speed sliding. Compared with ordinary metal materials, SKD11 has excellent wear resistance and can greatly extend the service life of the linear motor.

[0035] The sliding seat 5 is provided with a mounting surface 53, and the mounting surface 53 is provided with a mounting hole 54. In this embodiment, the mounting surface 53 provides a flat surface, so that the sliding seat 5 can be easily mounted on other components or equipment. By aligning the sliding seat 5 with other components and using appropriate fixing devices (such as screws, bolts, etc.), the sliding seat 5 can be quickly and firmly installed in a desired position.

[0036] The sliding seat 5 is formed by processing aluminum alloy. In this embodiment, aluminum alloy has a lower density than other metal materials, which enables the sliding seat 5 processed by aluminum alloy to significantly reduce the weight of the entire linear motor. The lightweight design helps to reduce the inertia force of the motor, thereby improving its dynamic response performance and acceleration / deceleration capability. This is very beneficial for application scenarios that require high-speed operation and rapid positioning.

[0037] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
