Description

[Technical field]

[0001] This invention relates to a rotating device that uses the attractive or repulsive force between an electromagnet and a rotating permanent magnet, and that uses a Halbach array as a permanent magnet installation method to more effectively obtain the attractive or repulsive force between the electromagnet and the permanent magnet. Note that the Halbach array referred to here means that multiple permanent magnets are installed close to each other and arranged for the purpose of dispersing or concentrating magnetic force at a certain position. [Background technology]

[0002] In a rotating device that uses the attractive and repulsive forces of an electromagnet and a permanent magnet, a permanent magnet is placed on a rotating disk and an electromagnet is fixedly installed on its outer periphery to generate rotational power from the repulsive and attractive forces of the permanent magnet. As described in Reference 1, one permanent magnet is installed facing one electromagnet.

[0003] In Reference 1, although the magnetic force of an electromagnet is generated on both ends of the electromagnet, the attraction or repulsion with a single permanent magnet was used on only one side as in Reference 1, so the magnetic force on one side of the electromagnet was not utilized. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent application 2022-206778 Summary of the Invention [Problem to be solved by the invention]

[0005] The challenge was to place multiple permanent magnets facing each other on an electromagnet and find a way to effectively extract as much attractive and repulsive force as possible. [Means for solving the problem]

[0006] In Reference 1, the permanent magnet facing the electromagnet obtained an attractive or repulsive force with one permanent magnet for each electromagnet, but in order to obtain the maximum magnetic force from the electromagnet, multiple permanent magnets are placed opposite both ends of the electromagnet, and in order to utilize the magnetic force of the permanent magnets without waste, the magnetic force of the permanent magnets is made directional, in other words, a Halbach array is used, thereby obtaining an attractive or repulsive force more effectively. Effect of the Invention

[0007] As shown in Figure 2, in Reference 1, one permanent magnet 1 is placed for one electromagnet M on only one side of the electromagnet, but by placing permanent magnet 2 behind electromagnet M, and placing permanent magnets on both ends of the electromagnet, it is possible to obtain an attractive or repulsive force that is double that of Reference 1.

[0008] As shown in FIG. 3, in addition to the permanent magnet 2, two more permanent magnets 7, 8, 9, and 10 arranged in a Halbach array are installed above and below the permanent magnets 1 and 2, in front of and behind the electromagnet. This increases the attractive or repulsive force with the electromagnet, allowing the rotating device to obtain greater rotational power. [Brief description of the drawings]

[Diagram 3] FIG. 11 is a diagram showing the installation of a permanent magnet when an electromagnet is installed horizontally (Example 3). [Figure 4] FIG. 13 is a diagram showing the installation of permanent magnets when an electromagnet is installed vertically (Example 4). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] As in Reference 1, the permanent magnets and electromagnets are placed in a straight line along the straight line that divides the disk. However, in Reference 1, one permanent magnet (permanent magnet 1) was placed only on one side of the disk toward the center as seen from the electromagnet, i.e., on the inside of the disk as seen from electromagnet M, facing the center line of the magnetic force. However, in this example, permanent magnet 2 was also placed on the outside of the disk as seen from the electromagnet.

[0011] In Figure 1, electromagnet M is set up so that the center line of the magnetic force of electromagnet M and the center lines of the magnetic forces of permanent magnets 1 and 2 are aligned at both ends of electromagnet M.

[0012] In Figure 3, when viewed from the center of the disk, the permanent magnet 1 is placed on the center side of the electromagnet M. The permanent magnets 1 are placed the same number as the number of divisions of the disk.

[0013] In Figure 3, when viewed from the center of the disk, permanent magnets 2 are placed outside electromagnet M. The number of permanent magnets 2 is the same as the number of divisions of the disk.

[0014] In Figure 3, when viewed from the center of the disk, inside the electromagnet M, permanent magnets 7 and 8 are installed above and below the permanent magnet 1. The permanent magnets 7 and 8 are installed in the same number as the number of divisions of the disk.

[0015] In Fig. 3, permanent magnets 9 and 10 are placed above and below permanent magnet 2 outside electromagnet M when viewed from the center of the disk. The permanent magnets 9 and 10 are placed in the same number as the number of divisions of the disk.

[0016] The central lines of magnetic force of the permanent magnets 7 and 8 form a straight line.

[0017] The central lines of magnetic force of the permanent magnets 9 and 10 form a straight line.

[0018] The center line of magnetic force of permanent magnets 7 and 8 intersects with the center line of magnetic force of electromagnet M at a right angle inside the disk of electromagnet M.

[0019] The center line of magnetic force of permanent magnets 9 and 10 intersects with the center line of magnetic force of electromagnet M at a right angle outside the disk of electromagnet M.

[0020] The intersection of the center line of the magnetic force of the permanent magnets 7 and 8 and the center line of the magnetic force of the electromagnet M is located midway between the electromagnet M and the permanent magnet 1.

[0021] The intersection of the center line of magnetic force of the permanent magnets 9 and 10 and the center line of magnetic force of the electromagnet M is located midway between the electromagnet M and the permanent magnet 2 .

[0022] The polarities of the magnetic forces of the permanent magnets 1, 7, and 8 face the same polarity at the intersection of the center line of the magnetic forces of the permanent magnets 7 and 8 and the center line of the magnetic force of the electromagnet M.

[0023] The polarities of the magnetic forces of the permanent magnets 2, 9, and 10 face the intersection of the center line of the magnetic force of the permanent magnets 9 and 10 and the center line of the magnetic force of the electromagnet M with the same polarity.

[0024] The center line of magnetic force of the permanent magnets 1, 7, and 8 is on a plane perpendicular to the center line dividing the disk.

[0025] The center line of magnetic force of the permanent magnets 2, 9, and 10 is on a plane perpendicular to the center line dividing the disk.

[0026] As for the permanent magnets 7 and 8, when viewed from the side along the center line of the magnetic force of the electromagnet M, the permanent magnet 7 is placed above the center line and the permanent magnet 8 is placed below it.

[0027] As for the permanent magnets 9 and 10, when viewed from the side along the center line of the magnetic force of the electromagnet M, the permanent magnet 9 is placed above the center line and the permanent magnet 10 is placed below it.

[0028] The permanent magnets 1, 2, 7, 8, 9, and 10 are placed close to the electromagnet M but not in contact with it.

[0029] The magnetic force of the permanent magnets 1, 2, 7, 8, 9, and 10 is uniform in terms of magnetic force, weight, volume, and shape.

[0030] When the center line of the magnetic force of the permanent magnet approaches closest to the center line of the magnetic force of the electromagnet, an attractive or repulsive force acts between the electromagnet and the permanent magnet, and a rotational force is generated in the disk every time the power to the electromagnet is turned on and off. EXAMPLES

[0031] Figure 1 shows the placement of electromagnet M and permanent magnets 1 and 2 when the disk is divided into four. In Reference 1, only permanent magnet 1 was placed inside the disk of electromagnet M, but a new permanent magnet 2 was also placed on the outside of the disk. Permanent magnets 1 and 2 are placed as close as possible to each other and at equal intervals on both ends of electromagnet M.

[0032] The center line of the magnetic force of permanent magnet 1 is set so as to be aligned with the center line of the magnetic force of permanent magnet 2. In other words, the center line of the magnetic force of electromagnet M and the center lines of the magnetic forces of permanent magnets 1 and 2 are set so as to be aligned.

[0033] The center line of magnetic force of electromagnet M and the center line of magnetic force of permanent magnets 1 and 2 are in a straight line, but are installed so that they coincide or are parallel to the center line of the disk.

[0034] Permanent magnets 1 and 2 are installed one on each end of the electromagnet, and the electromagnet M and permanent magnets 1 and 2 are installed as close as possible to each other on the center line of their respective magnetic forces. This is because the closer the gap between the electromagnet and the permanent magnet, the stronger the attractive or repulsive force.

[0035] The polarity of the permanent magnets 1 and 2 to be installed is such that either the south pole or the north pole is aligned toward the center of the disk on both ends of the electromagnet M.

[0036] When current flows through an electromagnet, if the polarity of the electromagnet and the permanent magnet are different, an attractive force is generated on both sides of the electromagnet, resulting in an attractive force that is doubled in Reference 1. Also, if the polarity of the electromagnet is the same as the polarity of the permanent magnet, a repulsive force that is doubled in Reference 1 is generated, resulting in rotational power. EXAMPLES

[0037] In the first embodiment, the electromagnet M is installed so that the center line of the magnetic force of the electromagnet is aligned or parallel to the center line of the disk, but in this embodiment, the center line of the magnetic force of the electromagnet M is installed perpendicular to the center line of the disk.

[0038] The center line of magnetic force of electromagnet M and the center line of magnetic force of permanent magnets 1 and 2 are installed so that they are in a straight line; in other words, the center lines of magnetic force of permanent magnets 1 and 2 are installed perpendicular to the center line of the disk, and are installed equidistantly close to both ends of electromagnet M.

[0039] The polarity of the magnetic force of the permanent magnets 1 and 2 is set so that either the S pole or the N pole is aligned on either the top or bottom.

[0040] If electromagnet M is placed perpendicular to the center line of the disk, permanent magnets 1 and 2 will be located above and below electromagnet M, so that the center lines of the magnetic force of the permanent magnets will be at the same position from the center along the outer periphery of the disk.

[0041] In the first embodiment, the permanent magnet 1 has a smaller radius of rotation than the permanent magnet 2, and therefore, according to the principle of leverage, the stress on the rotation axis of the permanent magnet 1 is smaller than that of the permanent magnet 2.

[0042] In the second embodiment, it is possible to install an electromagnet whose length exceeds the radius of the disk on the outer periphery of the disk, i.e., it is possible to install a larger and more powerful electromagnet on the outer periphery of the disk. EXAMPLES

[0043] In the first embodiment, one permanent magnet was installed on each end of the electromagnet M that was aligned or parallel to the center line of the disk, but as shown in Fig. 3, permanent magnets 7, 8 and 9, 10 were installed on both ends of the electromagnet. The permanent magnets 7, 8, 9, 10 are uniform in magnetic force, weight, volume, and shape. Also, Fig. 3 shows the center lines of the magnetic forces of the electromagnet and the permanent magnets.

[0044] The center lines of magnetic force of permanent magnets 7 and 8 form the same straight line and intersect at a right angle with the center line of magnetic force of electromagnet M at the midpoint between electromagnet M and permanent magnet 1, forming an intersection point, and the center lines of magnetic force of permanent magnets 7 and 8 are perpendicular to the center line of the disk and coincide with the vertical plane of the center line of the disk.

[0045] Permanent magnets 7 and 8 are vertically above and below the intersection and face each other at equal intervals in close proximity to each other without coming into contact with the electromagnets. The polarity of their magnetic force faces the permanent magnet 1 and is the same as that of the permanent magnet 1.

[0046] The center lines of magnetic force of permanent magnets 9 and 10 form the same straight line and intersect at a right angle with the center line of magnetic force of electromagnet M at the midpoint between electromagnet M and permanent magnet 2, forming an intersection point, and the center lines of magnetic force of permanent magnets 9 and 10 are perpendicular to the center line of the disk and coincide with the vertical plane of the center line of the disk.

[0047] Permanent magnets 9 and 10 face each other at equal intervals vertically above and below the intersection, close enough not to come into contact with the electromagnets, and the polarity of their magnetic force faces the same as that of permanent magnet 2.

[0048] In Figure 3, if the polarity of electromagnet M becomes a north pole on the center side of the disk, an attractive force acts between electromagnet M and the polarity of the magnetic force of permanent magnets 1, 7, and 8. In that case, the polarity of electromagnet M becomes a south pole on the opposite side, so an attractive force also acts between electromagnet M and permanent magnets 2, 9, and 10.

[0049] In Figure 3, if the polarity of electromagnet M becomes a south pole on the center side of the disk, a repulsive force acts between electromagnet M and the polarity of the magnetic force of permanent magnets 1, 7, and 8. In that case, the polarity of electromagnet M becomes a north pole on the opposite side, so a repulsive force also acts between electromagnet M and permanent magnets 2, 9, and 10.

[0050] The closer the distance between the electromagnets 7, 8, 9, and 10 and the electromagnet M, the greater the attractive or repulsive force, so the magnets are placed as close together as technically possible.

[0051] The center lines of magnetic force of permanent magnets 1, 2, 7, 8, 9, and 10 coincide with the perpendicular plane of the center line of the disk. EXAMPLES

[0052] In Figure 3, the center line of magnetic force of electromagnet M is set in a straight line or parallel to the center of the disk, but in Figure 4, it is set at a right angle to the center line of the disk.

[0053] In Figure 4, permanent magnets 1 and 2 are installed close to each other at both ends of electromagnet M with their polarities aligned to face either above or below the electromagnet, and the center line of the magnetic force of permanent magnet 1 below electromagnet M and permanent magnet 2 above electromagnet M form a straight line.

[0054] In FIG. 4, the center lines of the magnetic forces of the permanent magnets 7 and 8 form the same straight line and intersect with the center line of the electromagnet M at a right angle to form an intersection, and the permanent magnets 7 and 8 are equidistant from the intersection to the outside and inside of the disk.

[0055] In FIG. 4, the center lines of magnetic force of the permanent magnets 9 and 10 form the same straight line and intersect with the center line of the electromagnet at a right angle to form an intersection, and the permanent magnets 9 and 10 are equidistant from the intersection to the outside and inside of the disk.

[0056] In FIG. 4, the center line of the magnetic force of the permanent magnets 7 and 8 and the center line of the magnetic force of the permanent magnets 9 and 10 are parallel to each other at both the upper and lower ends of the electromagnet M.

[0057] In FIG. 4, the central line of magnetic force of permanent magnets 1 and 2 is aligned with the central line of the electromagnet, and they are placed close to the electromagnet on both ends of the electromagnet.

[0058] The center line of magnetic force of electromagnet M and the center lines of magnetic force of permanent magnets 1, 2, 7, 8, 9, and 10 coincide with a plane perpendicular to the center line of the disk.

[0059] When a current flows through an electromagnet, if the polarity of the electromagnet and the polarity of the permanent magnet are different, the electromagnet An attractive force is generated on both sides of the magnet, and the attractive force is doubled in Reference 1. If the polarity of the electromagnet is the same as that of the permanent magnet, a repulsive force is doubled in Reference 1, resulting in rotational power.

[0060] The advantage of placing the center line of the magnetic force of the electromagnet perpendicular to the center line of the disk is that in the case of embodiments 1 and 3, the length of the electromagnet cannot exceed the radius of the disk, but in the case of embodiments 2 and 4, it becomes possible to place an electromagnet with a length that exceeds the radius of the disk, making it possible to place a more powerful electromagnet that is longer than the radius of the disk.

[0061] In addition, since the electromagnets are longer, the permanent magnets 1, 7, and 8 are positioned closer to the central axis in the first and second embodiments, but it is better to position the permanent magnets that receive the attractive or repulsive force from the electromagnets on the circumferential side. This has the advantage that the stress on the rotating shaft is larger due to the principle of leverage, and is effective in making effective use of the magnetic force of the electromagnets. [Industrial Applicability]

[0062] Instead of one permanent magnet per electromagnet as in Reference 1, by placing two or more permanent magnets opposite one electromagnet, it is possible to generate greater attractive or repulsive forces and use them as rotational power, which is effective as a green energy source and can contribute to humanity.
