Description

[Technical field]

[0001] The present invention relates to the field of rotating magnetic devices, and more particularly to a magnetic toroid and a magnetically actuated rotating coupling device comprising the magnetic toroid. [Background technology]

[0002] Various rotating machines have been developed using electromagnetism. For example, in an electric induction motor, an alternating electromagnetic force is generated between the rotor and stator of the induction motor, causing the rotor to rotate in a direction according to the direction of rotation of the electromagnetic force. A shaft is mechanically coupled to the rotor, and the shaft can then be rotated by actuating a mechanical load.

[0003] US Patent No. 7,116,018 (B2) discloses a vibration motor with a rotor rotation of about ±15° from the rest position. The rotor has two salient poles, facing each permanent magnet across a small air gap. The stator has a laminated stator core supporting the magnets and two salient poles, each supporting a stator coil. The stator poles face the rotor with a small air gap between the rotor poles. When no current flows through the coils, the rotor rests in a rest position with the poles aligned between the north and south poles of the magnets. During operation, the stator coils induce similar magnetic poles in the stator poles, which in turn induce similar magnetic poles in the rotor poles, causing the rotor to oscillate towards the opposite pole of the permanent magnet. When current flows in the opposite direction, the rotor swings towards the opposite pole of the magnet.

[0004] U.S. Patent Publication No. 20210336507 (A1) relates to an electric motor system including a rotor, a rotating shaft whose axis is displaceable relative to the center of rotation and outputs the rotational force of the rotor, and a stator that generates a rotational force in the rotor. The electric motor system includes a magnetic bearing that rotatably supports the rotating shaft by electromagnetic force, a permanent magnet attached to the rotating shaft and having a plurality of magnetic poles arranged in a circumferential direction centered on the axis of the rotating shaft, three detection elements that are arranged in the circumferential direction centered on the rotation center and detect magnetic flux generated from the permanent magnet, a coordinate detection unit that calculates the coordinates of the axis of the rotating shaft based on the output values ​​of two detection elements selected from the three detection elements according to the rotation angle of the rotating shaft, and a control unit that controls the magnetic bearing so that the axis of the rotating shaft approaches the center of rotation based on the coordinates calculated by the coordinate detection unit.

[0005] The above-mentioned prior art documents aim to provide improved rotating machines. However, they still suffer from a number of limitations and shortcomings. For example, the rotation of the rotating machine is driven by an electromagnetic field, which requires a large amount of power to be supplied to the stator of the rotating machine. Furthermore, the rotating machine is highly dependent on accurate magnetic field reversal to maintain operation.

[0006] Therefore, a need exists for a magnetically actuated rotary coupling device that can overcome the aforementioned limitations and drawbacks. Summary of the Invention

[0007] The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an exhaustive overview of the invention. Its sole purpose is to present some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented later.

[0008] The object of the present invention is to provide a magnetic torus that can provide a magnetic field with rotating polarity at every point around the torus as it rotates about its axis. This provides an interesting route for power generation since the stress variations are significantly less and the magnetic flux is generated in a more elegant way compared to rotating a single magnet over three high resistance regions (coils).

[0009] It is another object of the present invention to provide a magnetically actuated rotary coupling device that converts vibration or slight motion into torque and magnetic flux to generate electricity.

[0010] It is also an object of the present invention to provide a complex magnetic field on the inner or interior side of a magnetic toroid that can affect magnetic fluids such as oxygen and nanoparticle solutions.

[0011] These objectives may therefore be achieved by following the teachings of the present invention, which relates to a magnetic torus characterized by an angularly twisted Moebius torus, the cross section of which is a closed shape having at least four straight sides, each side of the Moebius torus being perpendicularly magnetized to form a magnetic torus, thereby generating a magnetic field with a rotating polarity around the magnetic torus as it rotates about its axis.

[0012] The present invention also relates to a magnetically actuated rotary coupling device comprising a first magnetic ring and a second magnetic ring disposed adjacent to the first magnetic ring, the first magnetic ring being rotatable about its own axis relative to the movement of the second magnetic ring when portions of their respective magnetic fields interact with each other.

[0013] The foregoing and other objects, features, aspects and advantages of the present invention will be better understood by carefully reading the detailed description provided below with appropriate reference to the accompanying drawings.

[0019] The present invention will now be described in accordance with various embodiments with reference to the accompanying drawings, in which reference numbers used in the drawings correspond to like elements throughout the description.

[0020] The present invention relates to a magnetic toroid (100) characterized by a Moebius-shaped toroid having an angular twist, the cross-section of the Moebius-shaped toroid being a closed shape having at least four straight sides, each side of the Moebius-shaped toroid being perpendicularly magnetized to form the magnetic toroid (100), thereby generating a magnetic field having a rotating or alternating polarity as the magnetic toroid (100) rotates about its axis.

[0021] According to one embodiment of the present invention, the Moebius loop may be twisted at 90 degrees, 180 degrees, 270 degrees, 360 degrees, or other angles.

[0022] According to one embodiment of the present invention, closed shapes include, but are not limited to, squares, rectangles, pentagons, hexagons, or other polygons having at least four straight sides.

[0023] According to one embodiment of the present invention, each side of the magnetic toroid (100) can have a north or south polarity, and each adjacent side to a given side can have a like or opposite polarity.

[0024] According to one embodiment of the present invention, the Möbius-shaped ring can be manufactured by 3D printing or additive manufacturing. The Möbius-shaped ring resembles a rectangular rod with one end twisted to some extent relative to the other end and the ends joined to form a closed loop. If the material of the Möbius-shaped ring is ferromagnetic, the Möbius-shaped ring can be magnetized perpendicularly by arranging magnetizing coils according to the orientation of the Möbius-shaped ring so that the magnetic field is perpendicular to the surface of the Möbius-shaped ring. If the material of the ring is not ferromagnetic, the ring can be magnetized perpendicularly by arranging multiple bar magnets according to the orientation of the Möbius-shaped ring so that the magnetic field is perpendicular to the surface of the Möbius-shaped ring.

[0025] According to one embodiment of the present invention, each side of the magnetic toroid (100) can have different magnetic strengths and patterns. For example, with respect to different magnetic strengths, a first side of the magnetic toroid (100) can be designed to have a significantly higher magnetic strength compared to other sides of the magnetic toroid (100). For example, with respect to different magnetic patterns, if the magnetic toroid (100) is created by attaching bar magnets to a Moebius-shaped toroid, each side of the magnetic toroid (100) can have a different shape and / or arrangement of the bar magnets, and thus can form different magnetic patterns.

[0026] According to one embodiment of the present invention, the complex magnetic field generated within or on the interior of the magnetic toroid (100) can have various effects on magnetic fluids, such as, but not limited to, oxygen and nanoparticle solutions.

[0027] The present invention will now be described in more detail with reference to Figures 1 to 3.

[0028] FIG. 1 shows a magnetic toroid (100) according to a preferred embodiment of the present invention. The magnetic toroid (100) is formed based on a Moebius-shaped toroid twisted by 180 degrees. FIG. 2 shows a half-cut of the magnetic toroid of FIG. 1 with a square cross section according to one of the embodiments. The cross section of the magnetic toroid (100) is square, and the four sides of the magnetic toroid (100) can be magnetized to have NNSS or NSNS poles. When the magnetic toroid (100) is rotating around its axis, a magnetic field with alternating or rotating polarity can be generated around the magnetic toroid (100). For example, a certain point around the magnetic toroid (100) is first subjected to a magnetic field with N polarity, and then begins to receive a magnetic field with S polarity as the magnetic toroid (100) rotates around its axis. 2, if we assume that the right side of the square cross section (designated R) has a north pole at point A, then the right side with the north pole (designated R') will move to the bottom of the square cross section at point B due to the twisting of the magnetic toroid (100). Similarly, if we assume that the top side of the square cross section has a south pole at point A, then the top side with the south pole will move to the left side of the square cross section at point B due to the twisting of the magnetic toroid (100).

[0029] The present invention also relates to a magnetically actuated rotary coupling device (200) comprising a first magnetic toroid (101) and a second magnetic toroid (102) disposed adjacent to the first magnetic toroid (101), the first magnetic toroid (101) being rotatable about its own axis relative to the motion of the second magnetic toroid (102) when portions of their respective magnetic fields interact with each other.

[0030] According to a preferred embodiment of the present invention, the movement of the second magnetic toroid (102) is tilted about an axis, however, the movement of the second magnetic toroid (102) may also be rotational about an axis.

[0031] According to a preferred embodiment of the present invention, the tilt axis of the second magnetic toroid (102) is perpendicular to the rotation axis of the first magnetic toroid (101). However, the tilt axis of the second magnetic toroid (102) and the rotation axis of the first magnetic toroid (101) may have other configurations.

[0032] According to one embodiment of the present invention, the portions of the interacting magnetic fields are of opposite polarity and the attractive force between them causes the first magnetic toroid (101) to rotate.

[0033] According to one embodiment of the present invention, the portions of each magnetic field that interact with each other have the same polarity, causing the first magnetic annular body (101) to rotate due to the repulsive forces between them.

[0034] FIG. 3 shows a magnetically actuated rotary coupling device (200) according to a preferred embodiment of the present invention. The magnetically actuated rotary coupling device (200) comprises a first magnetic toroid (101) and a second magnetic toroid (102) arranged near or adjacent to the first magnetic toroid (101). The first magnetic toroid (101) is formed based on a Möbius-shaped toroid twisted by 180 degrees. The cross section of the first magnetic toroid (101) is square, and the four sides of the first magnetic toroid (101) are magnetized to have NSNS poles. Similarly, the second magnetic toroid (102) is formed based on a Möbius-shaped toroid twisted by 180 degrees. The cross section of the second magnetic toroid (102) is square. However, the four sides of the second magnetic toroid (102) are magnetized to have NNSS poles. Furthermore, the first magnetic ring (101) is equipped with a vertical shaft (2) so that it can rotate around its own axis, the vertical axis. Meanwhile, the second magnetic ring (102) is equipped with a horizontal shaft (4) so ​​that it can rotate around a horizontal axis. An actuation means, such as a rod (6), is attached to the end of the second magnetic ring (102) to actuate it. When the rod (6) is moved up or down, the second magnetic ring (102) can tilt up or down around the horizontal axis. The tilting movement of the second magnetic ring (102) is similar to the movement of a teeter board, where the board is supported by a mid-pivot point between the two ends, and when one end goes down, the other end goes up. Parts of the magnetic fields between the first magnetic ring (101) and the second magnetic ring (102) then interact with each other, which causes the first magnetic ring (101) to rotate clockwise or counterclockwise around the vertical axis. When the magnetic field portions are of the same polarity, the first magnetic ring (101) rotates due to the repulsive forces between the magnetic fields. When the magnetic field portions are of opposite polarity, the first magnetic ring (101) rotates due to the attractive forces between the magnetic fields. The speed and direction of rotation of the first magnetic ring (101) can be selectively changed by adjusting the rod (6).

[0035] According to one embodiment of the present invention, the outer diameter of the first magnetic ring (101) is smaller than the inner diameter of the second magnetic ring (102), and the first magnetic ring (101) may be arranged concentrically within the second magnetic ring (102). When the second magnetic ring (102) is tilted or moved, the first magnetic ring (101) may rotate within the second magnetic ring (102) due to the interaction between the respective magnetic fields. According to another embodiment of the present invention, the outer diameter of the second magnetic ring (102) is smaller than the inner diameter of the first magnetic ring (101), and the second magnetic ring (102) may be arranged concentrically within the first magnetic ring (101). When the second magnetic ring (102) is tilted or moved, the first magnetic ring (101) may rotate around the second magnetic ring (102) due to the interaction between the respective magnetic fields. It is also readily understood that embodiments of the present invention are not limited to only two magnetic toroids (100). It is possible to have multiple magnetic toroids (100) concentrically arranged within the outermost magnetic toroid (100).

[0036] The present invention also relates to a magnet drive system comprising the aforementioned magnetically actuated rotary coupling device (200). The torque generated by the rotation of the first magnetic toroid (101) in the magnetically actuated rotary coupling device (200) can be utilized to drive other mechanical loads. For example, the vertical shaft (2) of the first magnetic toroid (101) can be connected to a turbine, a drive shaft, a propeller, or other mechanical load to transmit the generated torque of the first magnetic toroid (101). Furthermore, the magnetic flux generated by the rotation of the first magnetic toroid (101) can also be utilized to generate electricity by placing a coil alongside the first magnetic toroid (101). Furthermore, the magnet drive system can rely on wave forces or body motion to actuate the second magnetic toroid (102), which in turn rotates the first magnetic toroid (101) to generate electricity or drive other mechanical loads. For example, the magnet drive system can be used to generate electricity from the coil-covered first magnetic ring (101) to charge a mobile phone associated with the second magnetic ring (102) when the owner of the mobile phone is walking. It is expected that the magnet drive system can be used in other applications as well.
