Description

Technical Field

[0001] This invention relates to the field of linear motor platforms, and more specifically to a linear motor platform for high-precision positioning of marble. Background Technology

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. Previously, all linear motion had to be derived from rotating machinery using ball bearings, lead screws, belts, or pulleys. Linear motors offer many unique advantages over mechanical systems, such as high speed and very high positioning accuracy, high acceleration, virtually zero maintenance (no contact parts), no backlash, and the ability to complete linear motion using only the motor without the need for a lead screw drive.

[0003] Existing high-precision linear motor platforms use marble as a base to achieve stable operation, but this also makes movement difficult and usually requires the use of a forklift. However, forklifts are not convenient to move in some areas, and linear motors are prone to overheating due to high-speed movement, which undoubtedly greatly affects the performance of linear motors. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a linear motor platform for high-precision positioning of marble, comprising:

[0005] A marble platform and a sliding groove set at the bottom of the marble platform. The outer surface of the marble platform is uniformly provided with L-grooves. The inner wall of the L-grooves is provided with notches. The inner wall of the sliding groove is slidably connected to a support leg. The inner wall of the support leg is rotatably connected to a roller assembly. The outer surface of the marble platform is symmetrically provided with side blocks. The outer surface of the side blocks is rotatably connected to a pressure rod. The outer surface of the support leg is fixedly connected to a sliding rod.

[0006] Linear motor, a linear motor that drives the parts mounted on it to work, and a cooling assembly set on the outer surface of the linear motor;

[0007] The top of the marble platform is fixedly connected to the bottom of the linear motor. The outer surface of the marble platform is fixedly connected to the end of the side block near the linear motor. The two ends of the side block are rotatably connected to the inner wall of the pressure rod. The outer surface of the linear motor is fixedly connected to the end of the cooling assembly away from the pressure rod. The inner wall of the support leg is rotatably connected to the outer surface of the roller assembly.

[0008] The roller assembly includes a rubber wheel with a square groove on its outer surface. A cylinder is rotatably connected to the inner wall of the rubber wheel. Fixed plates are evenly distributed on the outer surface of the cylinder, and the outer surface of the cylinder is fixedly connected to one end of a top plate near the central axis of the rubber wheel. Rotating plates are rotatably connected to both ends of the fixed plates. A locking component is fixedly connected to the outer surface of the rubber wheel. Pointed cones are evenly distributed on the outer surface of the rotating plates, and the outer surface of the rotating plates is fixedly connected to the bottom of the pointed cones. A small block is rotatably connected to the bottom of the rotating plate, and a damping rod is fixedly connected to the end of the small block away from the rotating plate. This damping rod provides protection when the linear motor platform moves. During forward movement, the rubber wheel... As the rubber wheel rotates, the cylinder remains stationary. The square groove impacts the rotating plate. Because the top of the rotating plate is arc-shaped, the rubber wheel follows the rotation, ensuring smooth rotation. When the rubber wheel rotates in the opposite direction, the square groove of the rubber wheel impacts the opposite surface of the rotating plate. Since the opposite surface is not arc-shaped, it impacts the rotating plate, causing it to rotate on the top plate. As the rotating plate deflects, it presses against the damping rod, creating resistance. When the square groove is no longer in contact with the rotating plate, the damping rod resets the rotating plate, thus creating continuous obstruction. This design allows for better control of the applied tension when pushing on an incline or when workers are pushing a straight platform, making it easier to control when pushing downhill.

[0009] The locking component includes a disc, with a large ring rotatably connected to the end of the disc away from the rubber wheel. The inner wall of the large ring has evenly spaced spherical holes. A small ring is fixedly connected to the end of the disc near the large ring. The inner wall of the small ring has a perforation hole. A short tube is fixedly connected to the outer surface of the small ring. A retaining ring is fixedly connected to the inner wall of the small ring. A thin rope is fixedly connected to the bottom of the retaining ring. An end cap is fixedly connected to the end of the large ring away from the disc. A sphere is provided on the inner wall of the retaining ring, and the inner wall of the retaining ring is fixedly connected to the outer surface of the sphere.

[0010] A connecting ring is fixedly connected to one end of the disc near the large ring. A connecting block is fixedly connected to the inner wall of the connecting ring. A fixing post is fixedly connected to the end of the connecting block away from the connecting ring. A spring is fixedly connected to the outer surface of the fixing post. A sliding post is fixedly connected to the end of the spring away from the fixing post. An arc plate is fixedly connected to the end of the sliding post away from the spring. This provides a safety guarantee when the linear platform moves. Since factories often cannot guarantee that the ground is flat when the platform moves, there will be a slope. When pushing on a slope, the weight of the linear platform itself makes it difficult to control when going downhill, which can easily lead to danger. When rotating in the forward direction, since the large ring is stationary and the disc rotates, the connecting ring rotates. When the arc plate strikes the sphere, the sphere will not detach from the ring due to the thin rope at the bottom of the ring, thus not affecting its normal rotation. When a slope appears, the marble platform is turned around and moved in the opposite direction. Because the rubber wheel rotates slowly, it cannot reach the critical point of spring tension. When the movement speed is too fast and cannot be controlled, the huge centrifugal force will cause the sliding column to be thrown out and slide on the inner wall of the connecting ring, allowing the arc plate to fully contact the sphere and push the sphere out of the ring. The sphere rolls in the small ring and falls into the short tube. When the ball hole and the short tube are aligned, the sphere falls into the ball hole and gets stuck in the short tube and the ball hole, forming a brake to prevent danger in case of excessive movement.

[0011] The cooling assembly includes a long box, with a curved pipe fixedly connected to its outer surface. A square box is fixedly connected to the end of the curved pipe away from the long box. A push plate is slidably connected to the inner wall of the square box. A short rod is fixedly connected to the end of the push plate away from the curved pipe. A top plate is fixedly connected to the end of the short rod away from the push plate. A long pipe is fixedly connected to the top of the square box. A wind-facing component is fixedly connected to the end of the long pipe away from the square box. An annular pipe is fixedly connected to the bottom of the inner wall of the long box. A heat-conducting plate is fixedly connected to the outer surface of the annular pipe. Keyways are evenly arranged on the outer surface of the heat-conducting plate to cool the linear motor, ensuring its stability during high-speed movement and preventing overheating damage. Cooling is achieved by filling the long box with cooling oil. Simultaneously, the movement of the linear motor causes the top plate to be squeezed, and the push plate slides within the square box. The curved pipe applies thrust to the cooling oil, causing it to flow within the long box, achieving a better heat dissipation effect. The heat-conducting plate within the long box further enhances the heat dissipation effect, and in conjunction with the annular pipe, it can better remove the heat from the linear motor.

[0012] The wind-facing component includes a long cylinder with a spiral tube fixedly connected to its outer surface. The outer surface of the long cylinder has evenly spaced inclined grooves. Both ends of the long cylinder are fixedly connected to flared mouths. Inclined plates are fixedly connected to the outer surface of the long cylinder, and circular plates are fixedly connected to the inner walls of the flared mouths. The outer surface of the circular plates has evenly spaced inclined grooves, and the inner wall of the long cylinder has spiral grooves. This design helps the cooling component achieve a better cooling effect. The long cylinder is moved by a linear motor. The high-speed movement increases the airflow velocity, and the air enters the long cylinder through the inclined grooves of the circular plates. Due to the inclined grooves, the air enters in a rotating motion, forming a high-speed spiral wind that effectively carries away heat. The spiral grooves also allow the air to remain on the inner wall of the long cylinder for a longer period, ensuring more heat is carried away. Furthermore, the inclined grooves on the long cylinder allow hot air to be expelled more quickly during the outflow.

[0013] The end of the long box away from the curved tube is fixedly connected to the end of the linear motor near the side block, and the end of the long tube away from the square box is fixedly connected to the end of the spiral tube near the inclined plate.

[0014] The end of the cylinder away from the locking component is fixedly connected to the inner wall of the bracket, and the end of the damping rod away from the rotating plate is fixedly connected to the outer surface of the top plate.

[0015] The number of inclined plates is two, and the two inclined plates are symmetrically arranged in a spiral tube configuration.

[0016] The end of the disc furthest from the large ring is fixedly connected to the outer surface of the rubber wheel, and the end of the fixing post furthest from the end cap is fixedly connected to the end of the disc furthest from the rubber wheel.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention, by setting up a roller assembly, can provide protection when the linear motor platform moves. During forward movement, the rubber wheel rotates, while the cylinder does not rotate. The rubber wheel rotates on the surface of the cylinder, and the square groove impacts the rotating plate. Since the top of the rotating plate is arc-shaped, the rubber wheel will follow the rotation of the rotating plate, ensuring smooth rotation. When the rubber wheel rotates in the opposite direction, the square groove of the rubber wheel impacts the opposite surface of the rotating plate. Since the opposite surface is not arc-shaped, it will impact the rotating plate, causing the rotating plate to rotate on the top plate. As the rotating plate deflects, it will squeeze the damping rod, forming a resistance. When the square groove does not contact the rotating plate, the damping rod will reset the rotating plate, thus forming a continuous obstruction. This setting allows for better control of the applied pulling force when pushing the linear platform on an incline, making it easier to control when pushing downhill.

[0019] 2. This invention, by incorporating a locking component, provides a safety guarantee during the movement of the linear platform. Since factories often cannot guarantee a level ground surface during platform movement, slopes are common. When pushing downhill on a slope, the platform's own weight makes it difficult to control and can easily lead to danger. During forward rotation, because the large ring remains stationary while the disc rotates, the connecting ring rotates, and the arc plate impacts the sphere. Because the thin rope at the bottom of the retaining ring prevents the sphere from detaching from the retaining ring, its normal rotation is not affected. Furthermore, this invention addresses the issue of slopes. When the marble platform is turned around and moved in the opposite direction, the rubber wheel rotates slowly and cannot reach the critical point of spring tension. When the movement speed is too fast and cannot be controlled, the huge centrifugal force will cause the sliding column to be thrown out and slide on the inner wall of the connecting ring, so that the arc plate can fully contact the ball, pushing the ball out of the ring. The ball rolls in the small ring and falls into the short tube. When the ball hole and the short tube are aligned, the ball falls into the ball hole. The ball is stuck in the short tube and the ball hole, forming a brake to prevent danger in case of excessive movement.

[0020] 3. This invention, by incorporating a cooling component, can cool the linear motor, ensuring its stability during high-speed motion and preventing damage from overheating. Cooling is achieved by filling the long chamber with cooling oil. Simultaneously, the movement of the linear motor causes the top plate to be compressed, and the push plate slides within the square chamber. A thrust is applied to the cooling oil through a curved pipe, resulting in better heat dissipation within the long chamber. Furthermore, the heat-conducting fins within the long chamber further enhance the heat dissipation effect. Combined with the annular pipe, this effectively removes heat from the linear motor.

[0021] 4. By setting up an air-facing component, this invention can assist the cooling component to achieve a better cooling effect. The movement of the linear motor drives the long cylinder to move. Due to the high-speed movement, the airflow speed increases. The air enters the long cylinder through the inclined groove of the circular plate. Due to the setting of the inclined groove, the air enters in a rotating manner, forming a high-speed spiral wind, which can better remove heat. At the same time, the setting of the spiral groove can increase the time that the air flows and stays on the inner wall of the long cylinder, ensuring that more heat is carried away. In addition, the inclined groove opened on the long cylinder can expel hot air more quickly when it flows out. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0033] Example 1, using Figures 1-9The following describes a linear motor platform for high-precision positioning of marble according to an embodiment of the present invention.

[0034] like Figures 1-9 As shown, the present invention provides a linear motor platform for high-precision positioning of marble, comprising:

[0035] Marble platform 1, and a sliding groove 2 set at the bottom of marble platform 1. L-grooves 3 are evenly opened on the outer surface of marble platform 1. The inner wall of L-grooves 3 is notched 4. Support legs 5 are slidably connected to the inner wall of sliding groove 2. Roller assembly 6 is rotatably connected to the inner wall of support legs 5. Side blocks 9 are symmetrically arranged on the outer surface of marble platform 1. Pressure rods 10 are rotatably connected to the outer surface of side blocks 9. Sliding rods 11 are fixedly connected to the outer surface of support legs 5.

[0036] Linear motor 7, linear motor 7, and cooling assembly 8 disposed on the outer surface of linear motor 7;

[0037] The top of the marble platform is fixedly connected to the bottom of the linear motor 7. The outer surface of the marble platform is fixedly connected to the end of the side block 9 near the linear motor 7. The two ends of the side block 9 are rotatably connected to the inner wall of the pressure rod 10. The outer surface of the linear motor 7 is fixedly connected to the end of the cooling assembly 8 away from the pressure rod 10. The inner wall of the support leg 5 is rotatably connected to the outer surface of the roller assembly 6.

[0038] In use, the pressure rod 10 rotates on the side block 9, and the pressure rod 10 contacts the ground. Through leverage, one side of the marble platform 1 is lifted, pulling the slide rod 11 and sliding it in the L-groove 3 until it reaches the notch 4, so that the bracket extends beyond the bottom of the marble platform 1. The pressure rod 10 is then lowered, so that the roller assembly 6 on one side contacts the ground. The other side of the pressure rod 10 is then lifted, and the action is repeated until all four roller assemblies 6 are in contact with the ground, pushing the marble platform 1 to the placement location. The pressure rod 10 is then lifted, causing the marble platform 1 to tilt up and the bracket is placed into the slide groove 2, so that the marble platform 1 contacts the ground. The linear motor 7 is then powered on, and the linear motor 7 moves at high speed. At the same time, the cooling assembly 8 cools the heated linear motor 7.

[0039] The roller assembly 6 includes a rubber wheel 60, with a square groove 61 on its outer surface. A cylinder 62 is rotatably connected to the inner wall of the rubber wheel 60. Fixed plates 63 are evenly distributed on the outer surface of the cylinder 62, and the outer surface of the cylinder 62 is fixedly connected to one end of the top plate 86 near the central axis of the rubber wheel 60. Rotating plates 64 are rotatably connected to both ends of the fixed plates 63. A locking component 65 is fixedly connected to the outer surface of the rubber wheel 60. Pointed cones 66 are evenly distributed on the outer surface of the rotating plates 64, and the outer surface of the rotating plates 64 is fixedly connected to the bottom of the pointed cones 66. A small block 67 is rotatably connected to the bottom of the rotating plates 64, and a damping rod 68 is fixedly connected to the end of the small block 67 away from the rotating plates 64.

[0040] It can play a protective role when the linear motor 7 platform moves. When moving forward, the rubber wheel 60 rotates. Because the rubber wheel 60 rotates, the cylinder 62 does not rotate. The square groove 61 hits the rotating plate 64. Since the top of the rotating plate 64 is arc-shaped, the rubber wheel 60 will go along the rotating plate 64 to ensure smooth rotation. When the rubber wheel 60 rotates in the opposite direction, the square groove 61 of the rubber wheel 60 hits the opposite surface of the rotating plate 64. Since the opposite surface is not arc-shaped, it will hit the rotating plate 64, causing the rotating plate 64 to rotate on the top plate 86. When the rotating plate 64 deflects, it will squeeze the damping rod 68 to form a resistance. When the square groove 61 does not contact the rotating plate 64, the damping rod 68 will reset the rotating plate 64, thus forming a continuous blockage. This setting makes it easier to control the applied pulling force when pushing the linear platform on a slope, and makes it easier to control when pushing downhill. The pointed cone 66 increases the friction.

[0041] The locking component 65 includes a disc 651. A large ring 652 is rotatably connected to the end of the disc 651 away from the rubber wheel 60. The inner wall of the large ring 652 is evenly provided with ball holes 653. A small ring 654 is fixedly connected to the end of the disc 651 near the large ring 652. A leakage hole 655 is provided on the inner wall of the small ring 654. A short tube 656 is fixedly connected to the outer surface of the small ring 654. A retaining ring 657 is fixedly connected to the inner wall of the small ring 654. A thin rope 658 is fixedly connected to the bottom of the retaining ring 657. An end cap 659 is fixedly connected to the end of the large ring 652 away from the disc 651. A ball 650 is provided on the inner wall of the retaining ring 657, and the inner wall of the retaining ring 657 is fixedly connected to the outer surface of the ball 650.

[0042] A connecting ring 6510 is fixedly connected to one end of the disc 651 near the large ring 652. A connecting block 6511 is fixedly connected to the inner wall of the connecting ring 6510. A fixing post 6512 is fixedly connected to the end of the connecting block 6511 away from the connecting ring 6510. A spring 6513 is fixedly connected to the outer surface of the fixing post 6512. A sliding post 6514 is fixedly connected to the end of the spring 6513 away from the fixing post 6512. An arc plate 6515 is fixedly connected to the end of the sliding post 6514 away from the spring 6513.

[0043] It can provide a safety guarantee when the linear platform moves. Since the ground is often not flat when the platform moves in the factory, there will be a slope. When pushing on a slope, the weight of the linear platform itself makes it difficult to control when going downhill, which can easily lead to danger. When rotating in the forward direction, since the large ring 652 is stationary and the disc 651 rotates, the connecting ring 6510 rotates, and the arc plate 6515 hits the ball 650. Since the thin rope 658 at the bottom of the retaining ring 657 blocks the ball 650, the ball 650 will not fall off the retaining ring 657 and will not affect its normal rotation.

[0044] The cooling assembly 8 includes a long box 81, with a bent pipe 82 fixedly connected to its outer surface. A square box 83 is fixedly connected to the end of the bent pipe 82 away from the long box 81. A push plate 84 is slidably connected to the inner wall of the square box 83. A short rod 85 is fixedly connected to the end of the push plate 84 away from the bent pipe 82. A top plate 86 is fixedly connected to the end of the short rod 85 away from the push plate 84. A long pipe 88 is fixedly connected to the top of the square box 83. A wind-facing component 87 is fixedly connected to the end of the long pipe 88 away from the square box 83. An annular pipe 89 is fixedly connected to the bottom of the inner wall of the long box 81. A heat-conducting plate 810 is fixedly connected to the outer surface of the annular pipe 89. Keyways 811 are evenly distributed on the outer surface of the heat-conducting plate 810.

[0045] Cooling is achieved by filling the long box 81 with cooling oil. Simultaneously, the movement of the linear motor 7 causes the top plate 86 to be squeezed, and the push plate 84 slides within the square box 83. The curved pipe 82 applies thrust to the cooling oil, improving the flow within the long box 81 and achieving a better heat dissipation effect. The heat-conducting fins 810 within the long box 81 further enhance the heat dissipation effect. In conjunction with the annular pipe 89, they can better remove the heat from the linear motor 7. The triangular shape of the heat-conducting fins 810 allows for the placement of longer heat-conducting fins within a limited space. The triangle shape also facilitates better flow of cooling oil within the long box 81. The heat-conducting fins 810 have keyways 811 to facilitate the flow of hydraulic oil, enabling the removal of more heat. The hydraulic oil within the long box 81 and the cooling oil within the annular ring interact within the square box 83, resulting in faster cooling of the hydraulic oil. Furthermore, the annular pipe 89 and the heat-conducting fins 810 are in contact, further improving heat dissipation.

[0046] The wind-facing component 87 includes a long cylinder 871, a spiral tube 872 fixedly connected to the outer surface of the long cylinder 871, and inclined grooves 873 evenly distributed on the outer surface of the long cylinder 871. Bell mouths 874 are fixedly connected to both ends of the long cylinder 871, and inclined plates 875 are fixedly connected to the outer surface of the long cylinder 871. A circular plate 876 is fixedly connected to the inner wall of the bell mouth 874, and inclined grooves 877 are evenly distributed on the outer surface of the circular plate 876. Spiral grooves 878 are distributed on the inner wall of the long cylinder 871.

[0047] The linear motor 7 moves the long cylinder 871, which in turn moves the linear motor 7. The high speed of the movement increases the airflow. The air enters the long cylinder 871 through the inclined groove 877 of the circular plate 876. The inclined groove 877 causes the air to rotate as it enters, forming a high-speed spiral wind that can better remove heat. The spiral groove 878 allows the air to stay on the inner wall of the long cylinder 871 for a longer time, ensuring that more heat is removed. The inclined groove 873 on the long cylinder 871 can expel hot air more quickly when it flows out. The long tube 88 is a flexible pipe. When the push plate 84 moves inside the long box 81, it also squeezes the cooling oil into the long tube 88. By exchanging the low-temperature hydraulic oil in the spiral tube 872, the hydraulic oil is cooled down. Through the interaction between the hydraulic fluids, the heat of the hydraulic oil itself is reduced, and the heat of the linear motor 7 is removed.

[0048] Example 2, using Figures 1-8 The linear motor platform for high-precision positioning of marble according to the present invention will be described as follows.

[0049] like Figures 1-9 As shown, the present invention provides a linear motor platform for high-precision positioning of marble, based on Embodiment 1.

[0050] The locking component 65 includes a disc 651. A large ring 652 is rotatably connected to the end of the disc 651 away from the rubber wheel 60. The inner wall of the large ring 652 is evenly provided with ball holes 653. A small ring 654 is fixedly connected to the end of the disc 651 near the large ring 652. A leakage hole 655 is provided on the inner wall of the small ring 654. A short tube 656 is fixedly connected to the outer surface of the small ring 654. A retaining ring 657 is fixedly connected to the inner wall of the small ring 654. A thin rope 658 is fixedly connected to the bottom of the retaining ring 657. An end cap 659 is fixedly connected to the end of the large ring 652 away from the disc 651. A ball 650 is provided on the inner wall of the retaining ring 657, and the inner wall of the retaining ring 657 is fixedly connected to the outer surface of the ball 650.

[0051] A connecting ring 6510 is fixedly connected to one end of the disc 651 near the large ring 652. A connecting block 6511 is fixedly connected to the inner wall of the connecting ring 6510. A fixing post 6512 is fixedly connected to the end of the connecting block 6511 away from the connecting ring 6510. A spring 6513 is fixedly connected to the outer surface of the fixing post 6512. A sliding post 6514 is fixedly connected to the end of the spring 6513 away from the fixing post 6512. An arc plate 6515 is fixedly connected to the end of the sliding post 6514 away from the spring 6513.

[0052] When moving in the opposite direction, because the rubber wheel 60 rotates at a slow speed, it cannot reach the critical point of the spring 6513's tension. When the movement speed is too fast and cannot be controlled, the huge centrifugal force will cause the sliding column 6514 to be thrown out and slide on the inner wall of the connecting ring 6510, so that the arc plate 6515 can fully contact the ball 650, pushing the ball 650 out of the retaining ring 657. The retaining ring 657 is elastic and can hold the ball 650. The ball 650 rolls in the small ring 654 and falls into the short tube 656. When the ball hole 653 and the short tube 656 are aligned, the ball 650 falls into the ball hole 653. The ball 650 is stuck in the short tube 656 and the ball hole 653, forming a brake to prevent danger when the movement is too fast. Moreover, the ball 650 is made of rubber, which also provides a buffer when locked.

[0053] The specific workflow is as follows:

[0054] During operation, one side of the marble platform 1 is lifted, and the slide bar 11 is pulled, sliding within the L-groove 3 and into the notch 4, causing the support to extend beyond the bottom of the marble platform 1. The pressure bar 10 is then lowered, bringing one side of the roller assembly 6 into contact with the ground. The other side of the pressure bar 10 is then lifted, and this process is repeated until all four roller assemblies 6 are in contact with the ground, pushing the marble platform 1 to its designated location. The rubber wheel 60 rotates, and because it does not rotate, the cylinder 62 remains stationary. The square groove 61 impacts the rotating plate 64. Since the top of the rotating plate 64 is arc-shaped, the rubber wheel 60... It will follow the rotating plate 64 to ensure smooth rotation. It will rotate in the opposite direction of the rubber wheel 60. The square groove 61 of the rubber wheel 60 will hit the opposite surface of the rotating plate 64. It will rotate and move in the opposite direction. The locking component 65 will fix the rubber wheel 60. When the rotating plate 64 deflects, it will squeeze the damping rod 68, forming a resistance to lift the pressure rod 10, so that the marble platform 1 will tilt up and put the bracket into the slide groove 2. The marble platform 1 will contact the ground. The linear motor 7 will be powered on and move at high speed. At the same time, the cooling component 8 will cool the heated linear motor 7.
