Description
Technical Field
[0001] The invention belongs to the technical field of motors, and in particular to a magnetic levitation high-speed motor with an air-cooling structure. Background Art
[0002] The magnetic levitation high-speed motor is a high-end mechatronic device based on magnetic levitation technology and high-speed motor technology. It suspends the rotor in the air through electromagnetic force to achieve high-speed rotation without mechanical contact. It has significant advantages such as high efficiency, low noise and long life. It is widely used in aerospace, energy, industrial drive and other fields.
[0003] Due to their high speeds and high power density, magnetic levitation high-speed motors experience concentrated energy loss and significant heat generation, necessitating timely heat dissipation. Traditional cooling methods for magnetic levitation high-speed motors rely primarily on passive cooling or simple active cooling. These methods involve conducting heat through the metal (aluminum or cast iron) of the motor casing, radiating stator heat into the air, or installing a cooling impeller at the rear of the motor for cooling.
[0004] The main heat-generating components of a magnetic levitation high-speed motor are the internal stator winding, stator core, and rotor permanent magnet. However, after a long period of operation, it is difficult to perform targeted cooling of the components inside the magnetic levitation high-speed motor by relying solely on the heat conduction of the motor casing metal and the fan at the tail, resulting in high temperatures inside the components, thereby exacerbating the aging and damage of the stator winding and other components inside the magnetic levitation high-speed motor.
[0005] To this end, the present invention provides a magnetic levitation high-speed motor with an air-cooling structure. Summary of the Invention

[0008] Furthermore, the cooling mechanism also includes an extension component, which includes an extension frame that slides in the air outlet through a connecting rope. The extension frame is a through-design, and a first electromagnet is fixedly installed on the top of the extension frame, and a second electromagnet is fixedly installed in the fixed tube.
[0009] Furthermore, a stretching component is provided on the extension frame, and the stretching component includes two hollow rolls fixedly installed on both sides of the extension frame. The hollow rolls are connected to the interior of the extension frame, and the surface of the hollow rolls is provided with a plurality of through holes connected to the interior.
[0010] Furthermore, a guide plate is fixedly installed in the extension frame, and two sides of the guide plate are arc-shaped.
[0011] Furthermore, a protective net is fixedly installed at the air inlet of the frame.
[0012] Furthermore, a cleaning mechanism is provided on the surface of the fan blade, and the cleaning mechanism includes a fixed column fixedly mounted on the fan blade, a sliding rod is slidably connected to the fixed column through a spring, a third electromagnet is fixedly mounted on one end of the sliding rod, a fourth electromagnet is fixedly mounted on the fixed column, a fixing ring is fixedly mounted on the end of the sliding rod away from the third electromagnet, and a rubber impact ball is provided inside the fixing ring.
[0013] Furthermore, a reset mechanism is provided in the fixed ring, and the reset mechanism includes a push plate sliding in the fixed ring, one side of the push plate is in contact with the impact ball, and several elastic parts are fixedly installed in the fixed ring, one end of the elastic part is fixedly connected to the push plate.
[0014] Furthermore, auxiliary mechanisms are provided on both sides of the fixed ring, and the auxiliary mechanisms include an arc ring fixedly mounted on the fixed ring, the interior of the arc ring is connected to a sliding rod through a sealed sliding connection, and a cleaning plate is fixedly mounted on one end of the sliding rod.
[0015] Furthermore, the elastic member is a hollow elastic ball, a shrinkage hole is opened on the surface of the elastic member, the push plate and the fixed ring are sealingly and slidingly connected, and the arc ring is connected to the inside of the fixed ring.
[0016] Furthermore, a brush plate is clamped at one end of the cleaning plate, and a brush is provided on the surface of the brush plate.
[0017] The beneficial effects of the present invention are as follows: 1. The magnetic levitation high-speed motor with an air-cooling structure described in the present invention guides low-temperature gas into the corresponding fixed tube through a plurality of connecting tubes via fan blades. After the low-temperature gas enters the fixed tube, part of the low-temperature gas will be guided to the air outlet by the arc-shaped baffle, and then flow to the high-speed motor housing. The other part of the gas will flow through the first filter screen in the rectangular groove of the baffle, and then continue to flow to other parts in the main body of the magnetic levitation high-speed motor through the subsequent air outlet. Since the end of the fixed tube away from the connecting tube is closed, the gas entering the fixed tube will eventually flow into the main body of the magnetic levitation high-speed motor through the air outlet, thereby completing the cooling operation of the high-speed motor housing and parts in the main body of the magnetic levitation high-speed motor. Through the designed structure, when the main body of the magnetic levitation high-speed motor is in operation, its own rotor is used to drive the fan blades to rotate, thereby continuously sucking the external low-temperature gas into the main body of the magnetic levitation high-speed motor, thereby performing a real-time cooling operation on the internal parts. At the same time, the heat dissipation impeller at the tail of the magnetic levitation high-speed motor body is used to extract the high-temperature gas, so that fresh air is always maintained inside the magnetic levitation high-speed motor body, so that the magnetic levitation high-speed motor body is at a suitable temperature, thereby protecting the components inside the magnetic levitation high-speed motor body.
[0018] 2. In the magnetic levitation high-speed motor with an air-cooling structure described in the present invention, as the low-temperature gas enters the air outlet, most of the low-temperature gas will be guided to the hollow membrane by the arc-shaped guide plate, causing the wound hollow membrane to stretch out, thereby filling the gap between the two fixed tubes, thereby reducing the number of fixed tubes. While achieving reasonable cooling of the magnetic levitation high-speed motor body, the number of fixed tubes can be effectively controlled, thereby reducing costs. A small amount of low-temperature gas in the air outlet will flow directly out through the gap between the extension frame and the guide plate, thereby cooling the components directly below the air outlet. When the magnetic levitation high-speed motor body is no longer in operation, there is no gas in the fixed tube. At this time, the extension frame is reset under the action of the connecting rope, and the hollow membrane, due to its own elasticity, will reel and reset in the absence of gas. By resetting the components, the subsequent maintenance of the magnetic levitation high-speed motor body will not be affected.
[0019] 3. The present invention discloses a high-speed magnetic levitation motor with an air-cooled structure. The rotor of the high-speed magnetic levitation motor is driven into a low-speed rotation state. At this point, the third and fourth electromagnets within the fixed column are energized, causing them to repel each other. This causes the sliding rod, the third electromagnet, the spring, and other components to slide away from the fourth electromagnet, allowing the impact ball to contact the surface of the protective net. As the rotor drives the blades to rotate, the impact ball continuously strikes the protective net, causing impurities on the net to vibrate and fall off. The rotation of the blades slowly rotates the fan, preventing the impurities from being drawn into the housing. After striking the protective net, the impact ball slides and contracts within the fixed ring, compressing the elastic member with the push plate. This allows gas within the elastic member to enter the fixed ring through the shrinkage hole and be squeezed into the curved ring. The gas entering the curved ring pushes the internal sliding rod, causing it to slide out with the cleaning plate and brush plate, thereby wiping and cleaning the surface of the protective net. The brush plate is designed to compensate for areas that the impact ball cannot reach. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0033] like Figures 1 to 10 As shown, a magnetic levitation high-speed motor with an air-cooling structure described in an embodiment of the present invention includes a magnetic levitation high-speed motor body 1, a high-speed motor housing 2 and a rotor 3 are installed inside the magnetic levitation high-speed motor body 1, and a heat dissipation impeller 80 is installed at the tail of the magnetic levitation high-speed motor body 1; a cooling mechanism 10 is provided in the magnetic levitation high-speed motor body 1, and the cooling mechanism 10 includes a sleeve 11 fixedly installed on the outside of the magnetic levitation high-speed motor body 1, and fan blades 12 are provided inside the sleeve 11, and the fan blades 12 are fixedly installed on the rotor 3. An air inlet is opened on one side of the sleeve 11, and a micro pump 70 is fixedly installed inside the sleeve 11. Several hollow fixed tubes 14 are fixedly installed in the magnetic levitation high-speed motor body 1, and a connecting tube 13 connected to the interior is fixedly installed at one end of the fixed tube 14. The end of the connecting tube 13 away from the fixed tube 14 is connected to the micro pump 70 in the sleeve frame 11. Several air outlets 15 are provided at the bottom of the fixed tube 14. An arc-shaped baffle 16 is fixedly installed near the air outlet 15 of the fixed tube 14. A rectangular groove running through the baffle 16 is provided on one side of the baffle 16, and a first filter 17 is fixedly installed in the rectangular groove of the baffle 16.
[0034] During operation, when the magnetic levitation high-speed motor body 1 is started, the rotor 3 drives the blades 12 within the casing 11 to rotate, drawing in low-temperature gas from the outside through the air inlet of the casing 11. At this point, the micropump 70 (specifically, model: FMVP1004B two-drum micro vacuum pump) is activated, and the micropump 70 directs the gas drawn in by the blades 12 into several connecting tubes 13 and fixed tubes 14. After the low-temperature gas enters the fixed tubes 14, some of it is directed by the curved baffle 16 to the gas outlet 15, and then flows toward the high-speed motor housing 2. The remaining gas flows through the first filter 17 within the rectangular groove of the baffle 16, and then continues through the subsequent gas outlets 15 to other components within the magnetic levitation high-speed motor body 1. Since the end of the fixed tube 14 away from the connecting tube 13 is closed, the gas entering the fixed tube 14 will eventually flow into the magnetic levitation high-speed motor body 1 through the gas outlet 15, thereby completing the cooling operation of the high-speed motor housing 2 and components in the magnetic levitation high-speed motor body 1.
[0035] With the above-described structure, when the magnetic levitation high-speed motor body 1 is in operation, its rotor 3 drives the fan blades 12 to rotate, thereby continuously drawing low-temperature gas from the outside into the magnetic levitation high-speed motor body 1, thereby cooling the internal components in real time. Simultaneously, a heat dissipation impeller at the rear of the magnetic levitation high-speed motor body 1 (this is prior art and will not be described in detail here, and the rear of the magnetic levitation high-speed motor body 1 is provided with holes for heat dissipation) extracts the high-temperature gas, thereby constantly maintaining fresh air inside the magnetic levitation high-speed motor body 1, keeping the magnetic levitation high-speed motor body 1 at a suitable temperature, and thus protecting the components within the magnetic levitation high-speed motor body 1.
[0036] It should be noted that: due to the limited space inside the magnetic levitation high-speed motor body 1, the pump body that needs to be installed can only be the micro pump 70. The micro pump 70 can be used in conjunction with the fan blades 12 to suck the low-temperature gas at the far end into the magnetic levitation high-speed motor body 1, avoiding the situation where the direct use of the micro pump 70 can only suck in the high-temperature gas around the magnetic levitation high-speed motor body 1, resulting in insignificant heat dissipation and cooling effect.
[0037] Cooling mechanism 10 also includes an extension assembly 18, which includes an extension frame 181 that slides within air outlet 15 via a connecting rope 182. Extension frame 181 is a through-hole design. A first electromagnet 183 is fixedly mounted on the top of extension frame 181, and a second electromagnet 184 is fixedly mounted within fixed tube 14. Extension frame 181 is provided with a stretching assembly 19, which includes two hollow membrane rolls 191 fixedly mounted on either side of extension frame 181. Hollow membrane rolls 191 are connected to the interior of extension frame 181 and have a plurality of through-holes 192 formed on their surfaces that communicate with the interior. A deflector 20 is fixedly mounted within extension frame 181, with curved sides.
[0038] During operation, before the magnetic levitation high-speed motor body 1 is started, the first electromagnet 183 and the second electromagnet 184 are energized in advance, so that the two repel each other with like charges (the fixed tube 14 is made of anti-magnetic material, so the first electromagnet 183 and the second electromagnet 184 will not interfere with the magnetic field inside the magnetic levitation high-speed motor body 1), thereby allowing the extension frame 181 in the air outlet 15 to slide with the connecting rope 182 and the hollow roll film 191 in the direction away from the air outlet 15. As the low-temperature gas subsequently enters the outlet 15, the majority of it is directed by the curved guide plate 20 toward the hollow membrane 191, causing the retracted hollow membrane 191 to expand. (The hollow membrane 191 has a limited expansion range, and there is a certain gap between the magnetic levitation high-speed motor body 1 and the high-speed motor housing 2, so it is not completely in contact. Therefore, the hollow membrane 191 can expand and retract.) This fills the gap between the two fixed tubes 14, thereby reducing the number of fixed tubes 14. This effectively controls the number of fixed tubes 14 while achieving reasonable cooling for the magnetic levitation high-speed motor body 1, thereby reducing costs. A small amount of low-temperature gas within the outlet 15 flows directly out through the gap between the extension frame 181 and the guide plate 20, thereby cooling the components directly below the outlet 15. By designing multiple hollow membranes 191, they form an encircling pattern when expanded, thus comprehensively cooling the interior of the magnetic levitation high-speed motor body 1. After the gas is ejected through the through hole 192 of the hollow membrane 191, the airflow evenly covers the surface of the stator and other components, thereby quickly taking away the heat from various parts and avoiding the "heat dissipation dead corner" problem existing in traditional single-side or single-point cooling.
[0039] When the magnetic levitation high-speed motor body 1 is no longer in operation, the fixed tube 14 is depleted of gas. The extension frame 181 is then repositioned under the action of the connecting rope 182. The hollow roll film 191, due to its inherent elasticity, winds back into place in the absence of gas. This repositioning of the components prevents subsequent maintenance of the magnetic levitation high-speed motor body 1 from being affected.
[0040] A protective net 30 is fixedly installed at the air inlet of the sleeve frame 11, and a cleaning mechanism 40 is provided on the surface of the fan blade 12. The cleaning mechanism 40 includes a fixed column 41 fixedly installed on the fan blade 12, and a slide rod 42 is slidably connected to the fixed column 41 through a spring 43. A third electromagnet 44 is fixedly installed at one end of the slide rod 42, and a fourth electromagnet 45 is fixedly installed in the fixed column 41. A fixed ring 46 is fixedly installed at the end of the slide rod 42 away from the third electromagnet 44, and a rubber impact ball 47 is provided inside the fixed ring 46. A reset mechanism 50 is provided in the fixed ring 46. The reset mechanism 50 includes a push plate 52 that slides in the fixed ring 46, one side of the push plate 52 is in contact with the impact ball 47, and a plurality of elastic members 51 are fixedly installed in the fixed ring 46, and one end of the elastic member 51 is fixedly connected to the push plate 52.
[0041] Specifically, auxiliary mechanisms 60 are provided on both sides of the fixed ring 46. These include an arcuate ring 61 fixedly mounted on the fixed ring 46. A sliding rod 62 is sealed and slidably connected to the interior of the arcuate ring 61. A cleaning plate 63 is fixedly mounted on one end of the sliding rod 62. The elastic member 51 is a hollow elastic ball with shrinkage holes defined on its surface. The push plate 52 is sealed and slidably connected to the fixed ring 46, and the arcuate ring 61 is in communication with the interior of the fixed ring 46. A brush plate 64 with a bristle brush is secured to one end of the cleaning plate 63.
[0042] During operation, a protective net 30 is installed at the air inlet of the housing 11 to block impurities and dust. When the magnetic levitation high-speed motor body 1 is not in use, it is started and its rotor 3 is in a low-speed rotation state. At this time, the third electromagnet 44 and the fourth electromagnet 45 in the fixed column 41 are energized, causing the two like-sex magnets to repel each other, thereby causing the slide bar 42, the third electromagnet 44, the spring 43 and other components to slide away from the fourth electromagnet 45, so that the impact ball 47 contacts the surface of the protective net 30. As the rotor 3 drives the blades 12 to rotate, the impact ball 47 continuously strikes the protective net 30, causing impurities on the protective net 30 to vibrate and fall off. The rotation drives the blades 12 to rotate slowly, so that the fallen impurities are not sucked into the housing 11. After striking the protective net 30, the impact ball 47 slides and contracts into the retaining ring 46, compressing the elastic member 51 with the push plate 52. This causes the gas within the elastic member 51 to enter the retaining ring 46 through the contraction hole and be squeezed into the curved ring 61. The gas entering the curved ring 61 pushes the sliding rod 62 inside, causing it to slide outward, carrying the cleaning plate 63 and brush plate 64 with it, to wipe and clean the surface of the protective net 30. The brush plate 64 is designed to fill in areas that the impact ball 47 cannot reach.
[0043] Working principle: When the magnetic levitation high-speed motor body 1 is started and operated, the rotor 3 will drive the fan blades 12 in the sleeve 11 to rotate together, and the low-temperature gas from the outside will be sucked in through the air inlet of the sleeve 11. The fan blades 12 will then guide the low-temperature gas through several connecting pipes 13 into the corresponding fixed pipe 14. After the low-temperature gas enters the fixed pipe 14, part of the low-temperature gas will be guided to the outlet 15 by the arc-shaped baffle 16, and then flow to the high-speed motor housing 2. The other part of the gas will flow through the first filter 17 in the rectangular groove of the baffle 16, and then continue to flow through the subsequent outlets 15 to other components in the magnetic levitation high-speed motor body 1. Since the end of the fixed pipe 14 away from the connecting pipe 13 is closed, the gas entering the fixed pipe 14 will eventually flow into the magnetic levitation high-speed motor body 1 through the outlet 15, thereby completing the cooling operation of the high-speed motor housing 2 and components in the magnetic levitation high-speed motor body 1.
[0044] Before starting the magnetic levitation high-speed motor body 1, the first electromagnet 183 and the second electromagnet 184 are pre-energized, causing like charges to repel each other, thereby causing the extension frame 181 within the air outlet 15 to slide with the connecting rope 182 and the hollow film roll 191 away from the air outlet 15. As the low-temperature gas subsequently enters the air outlet 15, the majority of the low-temperature gas is guided by the curved guide plate 20 toward the hollow film roll 191, causing the rolled hollow film roll 191 to unfold and thereby fill the gap between the two fixed tubes 14. A small amount of low-temperature gas within the air outlet 15 flows directly out through the gap between the extension frame 181 and the guide plate 20, thereby cooling the components directly below the air outlet 15.
[0045] The protective screen 30 installed at the air inlet of the housing 11 serves to block impurities and dust. When the magnetic levitation high-speed motor body 1 is not in use, it is started and the rotor 3 is in a low-speed rotation state. At this time, the third electromagnet 44 and the fourth electromagnet 45 in the fixed column 41 are energized, causing the like-sense repulsion between them. This causes the slide bar 42, the third electromagnet 44, the spring 43, and other components to slide away from the fourth electromagnet 45, causing the impact ball 47 to contact the surface of the protective screen 30. As the rotor 3 drives the blades 12 to rotate, the impact ball 47 continuously strikes the protective screen 30, causing impurities on the protective screen 30 to vibrate and fall off. The rotation of the blades 12 drives the blades 12 to rotate slowly, preventing the falling impurities from being sucked into the housing 11. After striking the protective screen 30, the impact ball 47 slides and contracts into the fixed ring 46, thereby compressing the elastic member 51 with the push plate 52. This allows the gas in the elastic member 51 to enter the fixed ring 46 through the shrinkage hole and be squeezed into the arc ring 61. When the gas enters the arc ring 61 , it pushes the internal sliding rod 62 , causing the sliding rod 62 to slide out with the cleaning plate 63 and the brush plate 64 , thereby wiping and cleaning the surface of the protective net 30 .
