Abstract
Description
Technical Field
[0001] This utility model relates to a magnetically driven ring track motor, specifically a disc-shaped turntable and a fixed disc with magnets and electromagnets evenly installed around the circumference. The direction of the current is changed cyclically and regularly by a current reversing device, thereby changing the direction of the magnetic poles of the fixed disc electromagnet. The interaction force between the magnetic poles is used to achieve continuous unidirectional rotation of the turntable. Background Technology
[0002] The prior patent application CN202321624648.7, which describes the mechanical structure of a disc-shaped aircraft, has been granted. The company plans to continue to improve the research and development of the disc-shaped aircraft. The disc-shaped aircraft requires a special orbital system to provide the power source for the high-speed rotation of the winglets.
[0003] In the existing technology, the propeller of a propeller helicopter is powered by an aircraft engine. The aircraft engine is a highly complex and precise thermodynamic machine that is widely used. It works well to drive a propeller with a diameter of several meters to rotate at high speed. However, if it is to drive the winglets on the upper surface of a disc-shaped aircraft with a diameter of several meters to rotate at high speed, the aircraft engine is not capable of this task due to the weight of the disc winglets themselves and the relatively large wind resistance.
[0004] Current brushless motors consist of a rotor with several permanent magnets mounted on its sidewalls, and a stator composed of several electric coils. The number of permanent magnets typically exceeds the number of electric coils by two. The polarity of the magnets points towards the wall, and adjacent magnets have opposite polarities. The electric coils change their magnetic polarity by altering the direction of the current, thus achieving continuous rotation through the interaction of the magnetic poles. However, brushless motors are generally small in size, making them suitable for powering the propellers of rotary-wing drones. However, driving the high-speed rotation of the winglets on the surface of a disc-shaped aircraft several meters in diameter is beyond the capabilities of brushless motors due to the weight of the winglets themselves and the relatively high wind resistance.
[0005] Existing magnetic levitation track modules can levitate the working module and propel it forward rapidly, providing ideal power. However, the working module has many and complex components, is relatively heavy, has high manufacturing difficulty, and operates under harsh conditions, making it unsuitable for this task.
[0006] It is clear that there is no existing technology that can provide a matching power source for the high-speed rotation of the disc-shaped aircraft's winglets.
[0007] The applicant has developed a novel type of electric motor through extensive creative work. This motor consists of a rotating disc and a fixed disc connected by a shaft, forming a circular track motor. Electromagnets are evenly distributed and installed around the perimeter of both the rotating and fixed discs. Under the control of a current reversing device, the current alternately changes direction at equal time differences before passing through all the electromagnets on the fixed disc. This cyclical and regular change in the direction of the electromagnet poles on the fixed disc, combined with the repulsive and attractive forces between the magnetic poles of the fixed and rotating discs, enables continuous unidirectional rotation of the rotating disc. By appropriately setting the time difference and magnitude of the current changes, the rotational speed of the rotating disc can be effectively controlled. Utility Model Content
[0008] This invention provides a magnetically driven ring-shaped track motor with a relatively simple structure, fewer components, lower manufacturing difficulty, and less demanding operating conditions, thus overcoming the shortcomings of the aforementioned technologies. When applied to large-diameter disc-shaped aircraft, it can effectively drive the fins on the upper surface of the disc to rotate at high speed, solving the power problem for the high-speed rotation of the fins on the upper surface of disc-shaped aircraft. When applied to other large turntable workpieces, it can also provide efficient rotational power.
[0009] The technical solution of this utility model is as follows:
[0010] A magnetically driven circular track motor includes a turntable, a fixed plate, a one-way bearing, a turntable magnet, a fixed plate electromagnet, a current reversing device, a current regulator, a coupling shaft, and a circular track.
[0011] The circular track motor consists of a turntable and a fixed plate connected by a shaft. The turntable and fixed plate have similar diameters, and several magnets and electromagnets are evenly distributed and installed on the periphery of both plates, corresponding to each other. A one-way bearing is installed at the center of the turntable. A circular track is installed around the circumference of the contact point between the lower surface of the turntable and the upper surface of the fixed plate. Magnets are evenly distributed around the periphery of the upper surface of the turntable, with their magnetic poles pointing perpendicular to the plane of the fixed plate, and the magnetic poles of adjacent magnets always pointing in opposite directions. Electromagnets are also evenly distributed around the periphery of the lower surface of the fixed plate, corresponding to the magnets of the turntable, with their magnetic poles pointing perpendicular to the plane of the turntable, and the magnetic poles of adjacent electromagnets always pointing in opposite directions. The electromagnets installed on the fixed plate are controlled by the direction of the current, and under the control of the current reversing device, the current can change with the same time difference and the same direction before passing through all the electromagnets on the fixed plate. The electromagnets evenly distributed around the fixed plate can change the strength of the current passing through the electromagnets on the fixed plate under the control of the current regulator.
[0012] Preferably, a number of magnets are evenly distributed around the perimeter of the upper surface of the turntable. The number of magnets is appropriate. The magnets can be permanent magnets or electromagnets. During the working process, the polarity of the magnetic field of all the magnets on the turntable remains unchanged.
[0013] Preferably, an annular track is installed around the contact point between the lower surface of the turntable and the upper surface of the fixed plate. The annular track allows the turntable to rotate freely around the connecting shaft on the fixed plate, and also limits the distance between the upper and lower fixed plates and the turntable.
[0014] Preferably, the electromagnets are evenly distributed around the lower surface of the fixed plate. The connection between the electromagnets can be in parallel, series, or mixed. The direction of the current controls the direction of the electromagnet poles. Under the control of the current reversing device, the current can change direction at the same time difference and pass through all the electromagnets of the fixed plate and change the direction of the electromagnet poles, and ensure that the poles of adjacent electromagnets always point in opposite directions.
[0015] Preferably, the electromagnets evenly distributed around the fixed plate can change the strength of the current passing through all the electromagnets of the fixed plate under the control of the current regulator.
[0016] Preferably, the turntable and the fixed plate of the ring track motor are defined relative to each other, that is, the one-way bearing is modified to the center of the fixed plate, maintaining the original vertical position relationship of the two plates or changing the vertical position relationship, and the working effect is the same.
[0017] Preferably, the number of turntable magnets and the number of stationary electromagnets in the ring track motor are both even. The number of turntable magnets and the number of stationary electromagnets can be the same or differ by two.
[0018] Preferably, if the annular track of the annular track motor is designed to rotate in one direction, it can replace the one-way rotation function of the one-way bearing.
[0019] By adopting the structure of this utility model, the electromagnet of the fixed plate can be controlled by a current reversing device and a current regulator to cyclically and regularly change the direction of the current of the electromagnet of the fixed plate, thereby changing the direction of the magnetic poles and the strength of the magnetic force. Under the interaction of repulsion and attraction between the magnetic poles of the fixed plate and the turntable, the turntable can be continuously rotated in one direction.
[0020] This utility model discloses a magnetically driven circular track motor with the following characteristics:
[0021] The magnetically driven circular track motor consists of a turntable and a fixed plate connected by a shaft. The turntable and fixed plate have similar diameters, and several magnets and electromagnets are evenly distributed and installed around their perimeters. A one-way bearing is installed at the center of the turntable. The function of the one-way bearing is to ensure that the turntable always rotates in the same direction when the magnetic poles interact. A circular track is installed around the circumference of the contact point between the lower surface of the turntable and the upper surface of the fixed plate. The circular track allows the turntable to rotate freely around the shaft on the fixed plate, and also limits the distance between the upper and lower fixed plates and the turntable.
[0022] 2. Magnets are evenly distributed around the upper surface of the turntable, with their magnetic poles pointing perpendicular to the plane of the fixed plate, and the magnetic poles of adjacent magnets always pointing in opposite directions. The magnets can be permanent magnets or electromagnets, and the magnetic field polarity of the turntable magnets remains unchanged during the working process.
[0023] 3. Electromagnets are also evenly distributed around the lower surface of the fixed plate, corresponding one-to-one with the magnets of the turntable. Their magnetic poles point perpendicular to the plane of the turntable, and the magnetic poles of adjacent electromagnets always point in opposite directions. The electromagnets can be connected in parallel, series, or a combination thereof. Under the control of the current commutation device, the current changes direction with the same time difference before passing through all the electromagnets of the fixed plate. When the current direction changes, the magnetic pole direction of all the electromagnets on the fixed plate changes simultaneously.
[0024] 4. Electromagnets evenly distributed around the lower surface of the plate can change the strength of the current passing through all the electromagnets under the control of the current regulator.
[0025] Compared with the prior art, the advantages of this utility model are:
[0026] By employing the structure of this invention, the direction and strength of the magnetic poles of the fixed electromagnet can be cyclically and regularly changed through a current commutation device and a current regulator. Under the interaction of repulsion and attraction between the magnetic poles of the fixed and rotating disks, continuous unidirectional rotation of the turntable is achieved. If applied to large-diameter disc-shaped aircraft, it can effectively drive the fins on the upper surface of the disk to rotate at high speed, solving the power problem of disc-shaped aircraft. If applied to other large-disc workpieces, it can also provide efficient rotational power. Attached Figure Description

[0036] A magnetically driven circular track motor is characterized by comprising a turntable 1, a fixed plate 2, a one-way bearing 3, a turntable magnet 4, a fixed plate electromagnet 5, a current reversing device 6, a current regulator 7, a connecting shaft 8, and a circular track 9. Detailed Implementation
[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings. Example
[0038] like Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, a magnetically driven circular track motor is characterized by comprising a turntable 1, a fixed plate 2, a one-way bearing 3, turntable magnets 4, fixed plate electromagnets 5, a current commutation device 6, a current regulator 7, a connecting shaft 8, and a circular track 9; the connecting shaft 8 is located at the center of the fixed plate 2, and the one-way bearing 3 is located at the center of the turntable 1. The turntable 1 and the fixed plate 2 are connected by the one-way bearing 3 and the connecting shaft 8, and the diameters of the turntable 1 and the fixed plate 2 are similar; turntable magnets 4 are evenly distributed on the upper bottom surface of the turntable 1 at the edge of the turntable; fixed plate electromagnets 5 are evenly distributed on the lower bottom surface of the fixed plate 2 at the edge of the fixed plate, and the number and position of the turntable magnets 4 and the fixed plate electromagnets 5 correspond one-to-one; a circular track 9 is installed circumferentially at the contact point between the lower surface of the turntable 1 and the upper surface of the fixed plate 2; as shown Figure 8 As shown, the current regulator 7 is connected to the current commutation device 6, and the current commutation device 6 is connected to the fixed plate electromagnet 5; the current commutation device 6 is used to change the current direction of the fixed plate electromagnet 5; the current regulator 7 is used to change the current strength of the fixed plate electromagnet 5.
[0039] In this embodiment, the turntable magnet 4 is a permanent magnet or an electromagnet, and the magnetic field polarity of the turntable magnet 4 remains unchanged during the working process.
[0040] In this embodiment, the fixed plate electromagnets 5 are connected in parallel, series, or mixed. Under the control of the current commutation device 6, the current can change with the same time difference and the same direction and then pass through all the electromagnets 5 of the fixed plate 2.
[0041] In this embodiment, the electromagnets 5 evenly distributed around the fixed plate 2 can change the strength of the current passing through all the electromagnets 5 under the control of the current regulator 7.
[0042] In this embodiment, the number of turntable magnets 4 and the number of fixed plate electromagnets 5 are both even; the number of turntable magnets 4 is the same as or differs from the number of fixed plate electromagnets 5 by 2.
[0043] like Figure 3 and Figure 4 As shown, a circular track 9 is installed around the circumference of the contact point between the lower surface of the turntable 1 and the upper surface of the fixed plate 2. The circular track 9 allows the turntable 1 to rotate freely around the connecting shaft 8 on the fixed plate 2, and also limits the distance between the upper and lower turntable 1 and the fixed plate 2. Specifically, as shown... Figure 3 and Figure 4 At the contact point between the lower surface of the turntable and the upper surface of the fixed plate, concentric annular track grooves are provided on both surfaces. Rolling elements (such as balls or rollers) with limiting protrusions are embedded within the turntable track grooves, and these rolling elements contact the track grooves on the fixed plate. The rolling elements roll within the track grooves, allowing the turntable to rotate freely around its central axis on the fixed plate. Simultaneously, the limiting protrusions cooperate with the track grooves to precisely limit the distance between the upper and lower turntables and the fixed plate. If the annular track 9 is designed for unidirectional rotation, it can replace the unidirectional rotation function of the one-way bearing 3.
[0044] like Figure 2 and Figure 7 As shown, magnets 4 are evenly distributed around the upper surface of turntable 1, with their magnetic poles pointing perpendicular to the plane of fixed plate 2. The magnetic poles of adjacent magnets 4.1 and 4.2 always point in opposite directions. The magnets can be permanent magnets or electromagnets. During operation, the magnetic polarity of magnets 4.1 and 4.2 remains unchanged.
[0045] like Figure 5 As shown, electromagnets 5.1 and 5.2 are evenly distributed around the lower surface of the fixed plate 2. They can be connected in parallel, series, or a combination thereof. Under the control of the current reversing device 6, the current can change direction with the same time difference and simultaneously pass through all electromagnets 5.1 and 5.2 of the fixed plate 2. The electromagnets 5.1 and 5.2, evenly distributed around the lower surface of the fixed plate 2, can have their current strength altered by the current regulator 7.
[0046] like Figure 5 and Figure 6As shown, under the control of the current reversing device 6, the current can change direction with a precise time difference and simultaneously pass through all electromagnets 5.1 and 5.2 of the fixed plate 2, cyclically and regularly changing the magnetic pole direction of electromagnets 5.1 and 5.2 of the fixed plate 2. Since the magnetic pole direction of magnets 4.1 and 4.2 of the turntable 1 remains unchanged, while the magnetic pole direction of electromagnet 5 of the fixed plate 2 changes cyclically and regularly, when the magnetic pole polarities of magnets 4.1 and electromagnets 5.1 near the plate surface of the upper and lower plates are the same, a repulsive force is generated. Since the one-way bearing 3 in the center of the turntable 1 can only rotate in one direction, after the turntable 1 rotates by an angle in one direction, the magnetic pole of magnet 4.1 near the plate surface of the turntable 1 is opposite in polarity to the magnetic pole polarity of the next corresponding electromagnet 5.2 near the plate surface of the fixed plate 2, generating an attractive force, and the turntable 1 rotates by another angle in one direction. When magnet 4.1 of turntable 1 attracts electromagnet 5.2 of fixed plate 2, the current direction of electromagnets 5.1 and 5.2 is immediately changed by the current reversing device 6, and the magnetic pole direction is also changed. Under the repulsive force of the magnetic poles, magnet 4.1 of turntable 1 and electromagnet 5.2 of fixed plate 2 rotate again by an angle. In this way, by precisely changing the current direction of electromagnets 5.1 and 5.2 at precise timing, the magnetic poles of all the magnets between fixed plate 2 and turntable 1 generate a cyclical and regular repulsive and attractive interaction force, ultimately realizing the continuous unidirectional rotation of turntable 1.
[0047] By setting the operating parameters of the current reversing device 6 and the current regulator 7, and rationally changing the time difference and magnitude of the current direction of all electromagnets 5 passing through the fixed disk 2, the rotational speed of the turntable 1 can be effectively controlled. If applied to a large-diameter disc-shaped aircraft, it can effectively drive the fins on the upper surface of the disk to rotate at high speed, solving the power problem of the disc-shaped aircraft. If applied to other large turntable workpieces, it can also provide efficient rotational power.
