Magnetic levitation systems can be classified into electromagnetic levitation (EMS) systems and electric levitation (EDS) systems according to the principle of levitation force generation. Electrodynamic magnetic levitation systems (EDS) have significant advantages over electromagnetic magnetic levitation systems (EMS):

(2) The repulsive suspension system has self-stability and does not need complicated global control like electromagnetic magnetic suspension.
(3) Even if the power supply from the outside is stopped, the levitation system is not stopped as long as there is a speed.

Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
As shown in fig. 1, an electromotive magnetic levitation device based on halbach array includes at least two dual output shaft motors 100, at least two magnetic wheels 200, and at least one coaxial conveyor belt 300. Wherein each magnetic wheel 200 is provided with a halbach array magnet structure; each dual output shaft motor 100 is fixedly connected to each other, and each dual output shaft motor 100 is provided with a first output shaft 110 and a second output shaft 120. The first output shaft 110 of the dual output shaft motor 100 is mechanically connected to the center of the magnetic wheel 200 for driving the magnetic wheel 200 to rotate in the first direction or in the second direction, and the number of the magnetic wheels rotating in the first direction is equal to the number of the magnetic wheels rotating in the second direction. Each coaxial conveyor belt 300 is connected to the second output shaft 120 of the dual-output motor 100 corresponding to two magnetic wheels 200 with the same rotation direction, and is used for keeping the rotation speeds of the two magnetic wheels 200 with the same rotation direction consistent.
It should be noted that the first direction is a clockwise rotation direction, and the second direction is a counterclockwise rotation direction; or the first direction is a counterclockwise rotation direction and the second direction is a clockwise rotation direction. And is not particularly limited herein.
Specifically, when single magnet wheel 200 is levitated, the housing of dual-output motor 100 rotates against the direction in which magnet wheel 200 rotates, because the interaction force exists between the stator and the rotor of dual-output motor 100, and dual-output motor 100 is not fixed, so that the housing of dual-output motor 100 rotates. If no action is taken to give balance, the dual-output motor 100 housing of a single magnet wheel 200 will necessarily experience a net torque in one direction. In this embodiment, the number of the magnetic wheels rotating in the first direction is equal to the number of the magnetic wheels rotating in the second direction, so that the torques applied to the housing of the dual-output motor 100 are offset, and the rotation problem of the housing of the dual-output motor 100 is fundamentally solved.
Specifically, in order to overcome the problem that the net torque generated by the suspension device is not zero when the suspension device is suspended, the rotation directions of the adjacent magnetic wheels 200 are opposite, so that the counter torque forces applied to the adjacent magnetic wheels 200 when the adjacent magnetic wheels 200 rotate can be equal in magnitude and opposite in direction.
Further, the magnitude of the counter-torque is not only influenced by the inherent design of the device, but also the rotational speed of the magnetic wheel 200 is an important factor. In this embodiment, in order to overcome the rotational speed deviation between the magnetic wheels 200 and ensure that the same rotational speed is maintained between the magnetic wheels 200 having the same rotational direction, a coaxial belt 300 is added to the second output shaft 120 at the upper end of the dual output shaft motor 100 rotating in the same direction. Under the dragging of the coaxial conveyor belt 300, the double-output-shaft motor 100 with the same rotation direction can ensure almost the same rotation speed, and the rotation speed difference of the magnetic wheels 200 with the same rotation direction is further reduced.
In one embodiment, referring to fig. 1, the number of dual-output-shaft motors 100 and magnetic wheels 200 is four, the number of coaxial conveyors 300 is two, the four dual-output-shaft motors 100 are respectively fixed at four corners of a square shape, and the two coaxial conveyors 300 are respectively connected to the second output shafts 120 of the two dual-output-shaft motors 100 located at opposite corners.
In this embodiment, a square fixing bracket is disposed at one end of the dual-output-shaft motor 100 close to the first output shaft 110, four dual-output-shaft motors 100 are respectively fixed at four corners of the fixing bracket, and the second output shafts 120 of the dual-output-shaft motors 100 located at diagonal positions are connected to the coaxial conveyor belt 300, so that the rotational speeds of the second output shafts 120 of the dual-output-shaft motors 100 located at diagonal positions are consistent, and the rotational speeds of the magnetic wheels 200 located at diagonal positions are consistent.
It should be noted that the first output shaft 110 and the second output shaft 120 are both ends of the same output shaft, that is, the first output shaft 110 and the second output shaft 120 have the same rotation direction and rotation speed. Therefore, when dual output shaft motor 100 is started, two magnetic wheels 200 located diagonally have the same rotational direction and rotational speed. For example, if the rotation directions of the adjacent magnetic wheels 200 are opposite, one of the magnetic wheels 200 at one diagonal rotates clockwise, the two magnetic wheels 200 at the other diagonal rotate counterclockwise, and the rotation speeds of the four magnetic wheels 200 are the same, so that the counter-torque forces applied to the adjacent magnetic wheels 200 during rotation can be equal in magnitude and opposite in direction, and the problem of spin caused by non-zero net torque during levitation of the levitation device is solved.
In one embodiment, as shown in fig. 2, two coaxial belts 300 are respectively connected to the second output shafts 120 of the two dual-output-shaft motors 100 at adjacent angular positions, and the two coaxial belts 300 are parallel.
In this embodiment, four dual output shaft motors 100 may be divided into two groups, each group includes two adjacent dual output shaft motors 100, one group rotates clockwise, the other group rotates counterclockwise, and the coaxial conveyor belt 300 is additionally installed on the second output shaft 120 of the motor of the dual output shaft motor 100 of the same group, so as to ensure that the rotation directions and speeds of the magnetic wheels 200 of the same group are the same, and ensure that the counter-torque forces received by the two groups of magnetic wheels 200 when rotating are equal and opposite, thereby overcoming the problem of spin caused by non-zero net torque when the suspension device suspends.
In one embodiment, as shown in fig. 3, the magnetic wheel 200 is provided with an inner Halbach array magnet structure 210 and an outer Halbach array magnet structure 220, the inner Halbach array magnet structure 210 comprising 8 identical square permanent magnets M1, and the outer Halbach array magnet structure 220 comprising 16 identical square permanent magnets M1.
It should be noted that, as shown in fig. 4, the Halbach array magnet structure is a permanent magnet arrangement mode that combines a radial array and a tangential array, and this arrangement mode can use the least permanent magnets to be arranged on one side of the magnet array through a certain magnetization direction to generate the strongest one-way magnetic field, and the utilization ratio of the permanent magnets is very high, and the peak value of the magnetic field intensity of the single-side magnetic field is high, so that a larger induced electromotive force can be generated on the conductor plate when the single-side magnetic field moves relative to the conductor plate.
In this embodiment, the double halbach array magnet structure using the inner-ring halbach array magnet structure 210 and the outer-ring halbach array magnet structure 220 can greatly enhance the magnetic field strength, and the conventional square permanent magnet M1 is used to fill the magnetic wheel, thereby greatly reducing the cost of the permanent magnet while ensuring suspension.
It should be noted that the diameters of the halbach array magnet structures of the inner ring and the outer ring are determined according to the torque of the motor and the weight of the suspension device. For example, the diameter of the magnetic ring (i.e. the halbach array magnet structure of the inner ring and the outer ring) should be considered, the diameter is too large, the moment arm of the circular motion of the magnetic ring is lengthened, and the torque force of the motor may be insufficient; the diameter of the magnetic ring is too small, on one hand, the action range of the generated magnetic field is reduced, and sufficient repulsion force can not be generated to maintain the suspension of the whole device, and on the other hand, the diameter of the magnetic ring is too small, and after the torque force of the motor is enough to drive the magnetic ring, the situation of torque force overflow can occur.
Specifically, the square permanent magnet M1 has a side of 1 cm.
Specifically, square permanent magnet M1 is provided as a neodymium iron boron permanent magnet. The neodymium-iron-boron permanent magnet has the advantages of extremely high magnetic energy product, coercive force, high energy density and the like, and can meet the requirement of a high magnetic field intensity peak value. To achieve the most obvious effect, the present embodiment selects a square ndfeb magnet, N50, as the matrix of the M1 array of square permanent magnets.
In one embodiment, the inner halbach array magnet structure comprises 8 identical arc-shaped permanent magnets and the outer halbach array magnet structure comprises 16 identical arc-shaped permanent magnets.
In this embodiment, the magnetic wheel region can be filled as much as possible by filling the magnetic ring (inner-ring halbach array magnet structure and outer-ring halbach array magnet structure) with the arc-shaped permanent magnet, so that the magnetic field utilization rate can be effectively improved.
In one embodiment, see fig. 3, the distance between the magnetic wheels is greater than 10 cm.
In this embodiment, the distance between the magnetic wheels is greater than 10 cm to eliminate the eddy current effect.
In one embodiment, dual output shaft motor 100 is configured as a dc motor.
Specifically, dual output shaft motor 100 may select a motor having a large torque, a high rotational speed, and a light weight. The weight is light, and the suspension is easier to realize; the large torque enables the motor to maintain the current rotating speed when the motor is subjected to the resistance of an induction magnetic field, and the stable suspension high rotating speed can bring high induction current to the conductor plate, so that large repulsion force is generated.
As shown in fig. 5 and 6, the electric magnetic suspension system based on halbach array includes a top beam bracket 400 and a bar magnet M2, and the electric magnetic suspension device based on halbach array. The top beam support 400 is fixedly connected to any two adjacent double output shaft motors 100, the fixed point is located at one end of the second output shaft 120, and the bar magnet M2 is fixed on the top beam support 400.
In this embodiment, the bar magnet M2 is used to generate magnetic attraction with a magnetic rail (not shown in fig. 5 and 6) at the upper end of the device, so as to increase the levitation height of the device and make the magnetic induction strength of the magnetic field of the magnetic wheel 200 at a smaller value, so that the counter torque of the halbach array is reduced.
In one embodiment, as shown in fig. 5, 6 and 7, the halbach array-based electrodynamic magnetic levitation system further includes a conductor plate 600 and a guide magnetic rail 700, the conductor plate 600 is disposed at a lower end of the halbach array-based electrodynamic magnetic levitation apparatus, the guide magnetic rail 700 is disposed at an upper end of the halbach array-based electrodynamic magnetic levitation apparatus, and the guide magnetic rail 700 is provided with a rail permanent magnet M3 having a polarity opposite to that of the bar magnet.
Specifically, the penetration distance of the magnetic induction lines generated by the magnetic wheel 200 on the conductor plate 600 is limited and the magnetic induction lines are attenuated as the penetration distance increases, so that the induced current generated by the magnetic induction intensity of the magnetic induction lines after penetrating a certain distance is almost zero, and therefore, the conductor plate 600 does not need to be too thick. In order to maximize the induced current in the conductor plate 600, the present embodiment preferably selects a conductive material having a small resistivity, such as copper and aluminum. It is understood that aluminum is inexpensive but has poor electrical conductivity, while copper has good electrical conductivity but is quite expensive, and that a thick aluminum plate can have the same levitation effect as a thin copper plate without exceeding the penetration distance of the magnetic induction lines. Therefore, the two can be stacked for cost saving and reduced thickness of the conductor plate 600.
Specifically, due to the attraction between the track permanent magnet M3 and the bar magnet M2, the guiding magnetic track 700 provides an upward pulling force for the electromotive magnetic levitation device, so as to raise the levitation height of the electromotive magnetic levitation device, and the magnetic induction strength of the induced magnetic field of the magnetic wheel 200 is at a smaller value, thereby reducing the counter torque applied to the halbach array.
It can be understood that, in order to enable the electromagnetic levitation apparatus based on halbach array to levitate more smoothly, the guiding magnetic track 700 should satisfy two conditions: (1) if the distance between the trolley and the electric magnetic suspension device is too close to a certain distance, the trolley is attracted by the over-strong magnetic force, and if the distance is too far away, the trolley cannot be bound by the magnetic force; (2) the magnetic field action distance needs to be big, the vibration that some naked eyes are difficult to observe when this electronic magnetic suspension device suspends, when the space magnetic field intensity change gradient that this electronic magnetic suspension device is located is great, the magnetic force change that this electronic magnetic suspension device's vibration brought is just great, otherwise, when the space magnetic field intensity change of this electronic magnetic suspension device is less, the magnetic force change that this electronic magnetic suspension device's vibration was brought is just less, only magnetic field action distance is enough big can guarantee to have enough magnetic force to restrain this electronic magnetic suspension device, and the vibration influence of this electronic magnetic suspension device is minimum.
Specifically, according to the balance state among the electromotive magnetic levitation device, the conductor plate 600, and the guide magnetic track 700, the distance L1 between the conductor plate 600 and the magnetic wheel 200 and the distance L2 between the guide magnetic track 700 and the small bar magnet M2 can be obtained. For example, the balance relationship among the three is as follows:
F1+F2＝G
wherein F1 represents buoyancy force to which the electromotive magnetic levitation device is subjected, F2 represents attraction force of the guide magnetic track 700 to the electromotive magnetic levitation device, and G represents gravity to which the electromotive magnetic levitation device is subjected. After the permanent magnets and the dead weight of all positions of the electric magnetic suspension device are determined, functional relations exist between L1 and F1, and between L2 and F2, after the functional relations are determined, L1 can be easily obtained from experiments, and L2 can be obtained through the balance relations, so that the optimal distance between the guide magnetic track 700 and the conductor plate 600 can be obtained.
In the electric magnetic suspension device based on halbach array, the coaxial conveyor belt 300 is arranged on the second output shaft 120 of the double-output-shaft motor 100 rotating in the same direction, so that the rotation speeds of the two magnetic wheels 200 in the same rotation direction are ensured to be consistent, and the stability of the device is improved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
