- the length and the magnetic pole strength may be different.
- the magnetic pole strength of the stator pole 600 surrounding the outer ring may be increased by lengthening the length of the permanent magnet, but the spacing between adjacent stator plates and the rotor disk should be increased correspondingly after increasing the magnetic pole strength. Big.

- the rotor poles 500 on the rotor disks 301-314 are arranged in the same direction and angle, i.e., the axial projections of the rotor poles 500 on all of the rotor disks 301 ⁇ 314 coincide.
- the stator poles 600 on the stator plate 401414 are arranged, and the six stator poles 600 on the rear stator plate are rotated clockwise/counterclockwise around the axis with respect to the six stator poles 600 on the front stator plate.

- the number of rotor disks and stator plates is not limited to fourteen, and the number of rotor poles 500 and stator poles 600 is not limited to six.
- the number of rotor poles 500 in the rotor pole set depends on the diameter of the rotor disk and the size and pole strength of the rotor pole 500.

- the composite body 520 is formed by interleaving three layers of non-magnetic conductive materials 521, 523, and 527 and three layers of soft magnetic materials 522, 524, and 526.
- the number of layers of the non-magnetic conductive material and the soft magnetic material is not limited to three layers, which depends on a plurality of factors such as the magnetic field strength of the permanent magnet 510, the thickness of the non-magnetic magnetic material, and the like.
- the soft magnetic materials 522, 524, 526 form a magnetic induction magnetic pole under the magnetic field of the permanent magnet 510, and under the isolation of the non-magnetic magnetic materials 521, 523, 527, the magnetic induction magnetic pole strength of the soft magnetic material farther away from the permanent magnet 510 is weaker. So that the magnetic field strength on the right side of the permanent magnet 510 is much smaller than the left side.
- the composite body 520 is disposed on the right side of the permanent magnet 510 in the present embodiment for forming a field weakening region on the right side of the permanent magnet 510 even if the rotor magnetic pole 500 becomes a left strong right weak permanent magnet gradient magnetic pole.
- the composite body 520 can also be disposed on the left side of the permanent magnet 510, except that the magnetic fields on both sides are in a weak position.
- the length of the composite body 520 is approximately 1/5 to 1/2 of the length of the permanent magnet 510.

- the magnetic field strength of the left side of the permanent magnet 510 can reach 3 to 8 times of the right side.
- the permanent magnet 510 is generally oblong and has a length L that is several times greater than the thickness D to obtain a magnetic field of appropriate strength and direction.
- the thickness D of the permanent magnet 510 is again greater than a multiple of the W width so that the rotor pole 500 can quickly and easily traverse the weak magnetic region into the strong magnetic region during operation.
- the present invention is a difference in magnetic field strength between the two sides of the permanent magnet 510.
- the end surface of the permanent magnet 510 is inclined toward the left side by a straight line, an outer arc or an inner camber to increase the number of magnetic lines of the permanent magnet 510 toward the left side. In this embodiment, it is about 45°. Of course, other suitable angles are also possible, but the effect is much less when the end face has no inclination angle.
- the end face of the permanent magnet 510 forms an acute end on the right side, and an obtuse end on the left side. Since the length of the side on which the acute end is located is the longest, the magnetic field strength at the end is also the largest.

- the permanent magnet 510 of the rotor pole 500 when the permanent magnet 510 of the rotor pole 500 is located on the right side, the permanent magnet of the stator pole 600 is located on the left side.
- the rotor magnetic pole 500 can correspond to the stator magnetic pole 600 strong magnetic region Rm and the strong magnetic region Sm, and the weak magnetic region RB corresponds to the weak magnetic region SB. Therefore, the positive repulsive force of the rotor pole 500 from the right to the left of the stator pole 600 is much larger than the repulsive force of the leftward and rightward (reverse repulsion), thereby enabling the rotor disk 300 to be driven. Rotate clockwise.
- the rotor pole 500 and the stator pole 600 are mounted in such a manner that the thickness direction is parallel to the rotating shaft 200 during the mounting process, and the distribution of the magnetic lines of force is fully considered in the layout process.
- the distance between adjacent rotor poles 500 is preferably approximately equal to the sum of the effective magnetic distances of the two rotor poles 500.
- stator poles 600 are distributed on the inner circumferences of the stator plates 401 to 414, and the inner diameters of the stator plates 401 to 414 are only slightly larger than the diameters of the rotor disks 301 to 314, the stator poles 600 are arranged in the stator plates 401 to 414 similarly to the rotor poles 500. .
- the present invention adds an optimized design to the direction of force between them in addition to their layout.
- the direction of the repulsive force is tangent to the rotor discs 301-314; for this reason, the rotor pole 500 is longitudinally offset from the rotor during installation.
- the disk 301 314 is centered at a certain angle, and accordingly, the stator poles 600 are also offset from the same angle. In this embodiment, the angle is approximately 15 to 20 degrees.
- the eccentric angle is not limited to 15 ⁇ 20°, and it mainly depends on the distribution of magnetic lines of force.
- the present invention improves the use efficiency in order to eliminate the interference of the rotor poles 500 between adjacent rotor disks, so that the spacing between adjacent rotor disks is greater than the sum of the effective magnetic distances between the respective rotor poles 500. Accordingly, the distance between adjacent stator plates should also be greater than the sum of the effective magnetic distances between the respective stator poles 600.

下面结合附图及具体实施例对本发明作详细说明。 The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
图 1示出了本发明一个优选实施例中的三维永磁推斥动力机，它主要包括 机壳 100、 转轴 200、 穿设在转轴 200上的转子 300以及环绕转子 300的定子 400。 转子 300由间隔固定在转轴 200上、 并与转轴 200垂直的圆形转子盘 301〜314组成，定子 400由与转子盘 301~314——对应的环形定子板 401〜414
本发明中，转子盘 301 14上设有永磁转子磁极组，定子板 401 414上设 有永磁定子磁极组。 转子磁极组均包括多数个呈圆形阵列排列在转子盘 301-314的外周缘的转子磁极 500定子磁极组包括多数个呈圆形阵列排列在 定子板 401414的内周缘定子磁极 600。定子磁极 600与转子磁极 500的磁性 相同，. 即两者同时为 N或 S极， 以便两者之间能够产生推斥力驱动转子 300 带动转轴 200旋转； 另外， 两者最好形状和数量都相同， 但其长度和磁极强 度可不相同，例如，可通过加长永磁体长度来增加在外圈环绕的定子磁极 600 的磁极强度， 但增加磁极强度后相邻定子板和转子盘之间的间距应相应增大。 1 shows a three-dimensional permanent magnet repulsion power machine in a preferred embodiment of the present invention, which mainly includes a casing 100, a rotating shaft 200, a rotor 300 that is disposed on the rotating shaft 200, and a stator 400 that surrounds the rotor 300. The rotor 300 is composed of circular rotor disks 301 to 314 which are fixed to the rotating shaft 200 and are perpendicular to the rotating shaft 200. The stator 400 is composed of annular stator plates 401 to 414 corresponding to the rotor disks 301 to 314. In the present invention, the rotor disk 301 14 is provided with a permanent magnet rotor pole set, and the stator plate 401 414 is provided with a permanent magnet stator pole set. The rotor pole sets each include a plurality of rotor poles 500 arranged in a circular array on the outer circumference of the rotor disks 301-314. The stator pole sets include a plurality of inner circumferential stator poles 600 arranged in a circular array on the stator plates 401414. The stator pole 600 is the same as the magnet pole 500, that is, both are N or S poles so that a repulsive force can be generated between the two to drive the rotor 300 to rotate the shaft 200; in addition, the two are preferably the same in shape and number. However, the length and the magnetic pole strength may be different. For example, the magnetic pole strength of the stator pole 600 surrounding the outer ring may be increased by lengthening the length of the permanent magnet, but the spacing between adjacent stator plates and the rotor disk should be increased correspondingly after increasing the magnetic pole strength. Big.
本实施例中，转子盘 301^314和定子板 401~414均为十四个，每个转子磁 极组均包括六个转子磁极 500， 每个定子磁极组均包括六个定子磁极 600。 转 子盘 301~314 上的转子磁极 500 的排列方向和角度相同， 即所有转子盘 301^314上的转子磁极 500的轴向投影重合。 定子板 401414上的定子磁极 600在排列中，后一定子板上的六个定子磁极 600相对前一定子板上的六个定 子磁极 600整体绕轴心顺时针 /逆时针旋转一定角度 (本实施例中大约 4.285° )， 使各个定子板上的定子磁极的轴向投影不重合， 而密集分布在圆周上。 当然， 转子盘和定子板的数量也不局限于十四个， 转子磁极 500和定子磁极 600的 数量也不限于六个。 例如， 转子磁极组中转子磁极 500的数量取决于转子盘 的直径以及转子磁极 500的尺寸和磁极强度。一般在磁极强度一定的情况下， 转子盘的直径越大， 需要的转子磁极 500的数量就越多； 在转子盘直径一定 的情况下 > 磁极强度越小， 需要的转子磁极 500的数量就越少。 如果将所有定子板 401^414上的定子磁极 600的轴向投影在圆周上以:^ 84 编号， 则可以看出各个定子板上定子磁极 600的相对位置关系。如图 2所示， 第一个定子板 401上的六个定子磁极 600分别位于定子板所在圆周的第 1、 15、
29、 43、 57、 71号位置， 与定子板 401对应的第一个转子盘 301上的六个转 子磁极 500分别位于转子盘所在圆周上第 85、 86、 87、 88、 89、 90号位置。 如图 3所示， 第二个转子盘 302上的六个转子磁极 500的在转子盘所在圆周 上的位置不变，而第二个定子板 402上的六个定子磁极 600则相对定子板 40i 上的六个定子磁极 600整体绕圆心顺时针旋转了大约 4.285度，分别位于定子 板所在圆周的第 2、 16、 30、 44、 58和 72号位置。 依此类推， 第八个转子盘 308上的六个转子磁极 500的位置不变，而第八个定子板 408上的六个定子磁 极 600分别位于第 8、 22、 36、 50、 64和 78号位置 （如图 4所示）。 第十四 个转子盘 314上的六个转子磁极 500的位置不变， 而第十四个定子板 414上 的六个定子磁极 600分别位于第 14、 28、 42、 56、 74和 84号位置 （如图 5 所示）。 In this embodiment, the rotor disk 301 314 and the stator plates 401 - 414 are each of fourteen, each of the rotor pole sets includes six rotor poles 500 , and each of the stator pole sets includes six stator poles 600 . The rotor poles 500 on the rotor disks 301-314 are arranged in the same direction and angle, i.e., the axial projections of the rotor poles 500 on all of the rotor disks 301^314 coincide. The stator poles 600 on the stator plate 401414 are arranged, and the six stator poles 600 on the rear stator plate are rotated clockwise/counterclockwise around the axis with respect to the six stator poles 600 on the front stator plate. In the example, about 4.285°), the axial projections of the stator poles on the respective stator plates do not coincide, but are densely distributed on the circumference. Of course, the number of rotor disks and stator plates is not limited to fourteen, and the number of rotor poles 500 and stator poles 600 is not limited to six. For example, the number of rotor poles 500 in the rotor pole set depends on the diameter of the rotor disk and the size and pole strength of the rotor pole 500. Generally, in the case where the magnetic pole strength is constant, the larger the diameter of the rotor disk, the more the number of rotor poles 500 required; in the case where the diameter of the rotor disk is constant > the smaller the magnetic pole strength, the more the number of rotor poles 500 required less. If the axial directions of the stator poles 600 on all of the stator plates 401^414 are projected on the circumference to be numbered 84, the relative positional relationship of the stator poles 600 on the respective stator plates can be seen. As shown in FIG. 2, the six stator poles 600 on the first stator plate 401 are respectively located at the first, the 15th of the circumference of the stator plate. At positions 29, 43, 57, and 71, the six rotor poles 500 on the first rotor disk 301 corresponding to the stator plate 401 are located at the 85th, 86th, 87th, 88th, 89th, and 90th positions on the circumference of the rotor disk. . As shown in FIG. 3, the positions of the six rotor poles 500 on the second rotor disk 302 on the circumference of the rotor disk are unchanged, and the six stator poles 600 on the second stator plate 402 are opposite to the stator plate 40i. The upper six stator poles 600 are rotated clockwise around the center by approximately 4.285 degrees, respectively at positions 2, 16, 30, 44, 58 and 72 of the circumference of the stator plate. By analogy, the positions of the six rotor poles 500 on the eighth rotor disk 308 are unchanged, while the six stator poles 600 on the eighth stator plate 408 are located at 8, 22, 36, 50, 64, and 78, respectively. Number position (as shown in Figure 4). The positions of the six rotor poles 500 on the fourteenth rotor disk 314 are unchanged, while the six stator poles 600 on the fourteenth stator plate 414 are located at positions 14, 28, 42, 56, 74 and 84, respectively. (As shown in Figure 5).
如图 6所示，本发明中的转子磁极 500主要包括永磁体 510和设置在永磁 体 510侧部的复合体 520。复合体 520由三层非导磁材料 521、 523、 527和三 层软磁材料 522、 524、 526交错层叠而成。 当然， 非导磁材料和软磁材料的 层数不局限于三层， 其取决于永磁体 510的磁场强度、 非导磁材料的厚度等 多个因素。 软磁材料 522、 524、 526在永磁体 510的磁场作用下形成磁感应 磁极， 它在非导磁材料 521、 523、 527的隔离下， 使越远离永磁体 510的软 磁材料磁感应磁极强度越弱， 以使永磁体 510右侧磁场强度远小于左侧。 复 合体 520在本实施例中设置在永磁体 510的右侧， 用来在永磁体 510的右侧 形成弱磁区域， 即使转子磁极 500成为左强右弱的永磁梯度磁极。 当然， 复 合体 520也可以设置在永磁体 510的左侧， 只是两侧的磁场强弱倒换位置而 已。 另外， 本发明为使转子磁极 500的效果达到最佳， 使复合体 520的长度 大约为永磁体 510的长度的 1/5~1/2。 复合体 520太长时， 不但增加成本， 而
且易使转子磁极 500的磁力线数量减少。 复合体 520太短时， 其感应磁异极 易干扰到复合体 520端面的磁力线。另外，永磁体 510和复合体 520的所有端 面可为直线、外弧度和内弯度；而定子磁极 600的结构和转子磁极 500—样例 如上述。 As shown in FIG. 6, the rotor pole 500 of the present invention mainly includes a permanent magnet 510 and a composite body 520 disposed at a side of the permanent magnet 510. The composite body 520 is formed by interleaving three layers of non-magnetic conductive materials 521, 523, and 527 and three layers of soft magnetic materials 522, 524, and 526. Of course, the number of layers of the non-magnetic conductive material and the soft magnetic material is not limited to three layers, which depends on a plurality of factors such as the magnetic field strength of the permanent magnet 510, the thickness of the non-magnetic magnetic material, and the like. The soft magnetic materials 522, 524, 526 form a magnetic induction magnetic pole under the magnetic field of the permanent magnet 510, and under the isolation of the non-magnetic magnetic materials 521, 523, 527, the magnetic induction magnetic pole strength of the soft magnetic material farther away from the permanent magnet 510 is weaker. So that the magnetic field strength on the right side of the permanent magnet 510 is much smaller than the left side. The composite body 520 is disposed on the right side of the permanent magnet 510 in the present embodiment for forming a field weakening region on the right side of the permanent magnet 510 even if the rotor magnetic pole 500 becomes a left strong right weak permanent magnet gradient magnetic pole. Of course, the composite body 520 can also be disposed on the left side of the permanent magnet 510, except that the magnetic fields on both sides are in a weak position. Further, in order to optimize the effect of the rotor pole 500, the length of the composite body 520 is approximately 1/5 to 1/2 of the length of the permanent magnet 510. When the composite 520 is too long, it not only increases the cost, but Moreover, the number of magnetic lines of force of the rotor pole 500 is easily reduced. When the composite 520 is too short, the induced magnetic difference is likely to interfere with the magnetic lines of force on the end face of the composite 520. In addition, all end faces of the permanent magnet 510 and the composite body 520 may be a straight line, an outer arc and an inner camber; and the structure of the stator pole 600 and the rotor pole 500 are as described above, for example.
本发明在制作过程中，永磁体 510两侧的磁场强度差异要尽量拉大， 以提 高转子磁极 500使用效率， 本实施例中永磁体 510左侧的磁场强度可以达到 右侧的 3~8倍。 永磁体 510大体呈扁长形， 其长度 L大于厚度 D若干倍， 以 获取适当强度和方向的磁场。永磁体 510的厚度 D又大于 W宽度若干倍， 以 便转子磁极 500能够在运行过程中能快速、 容易地从弱磁区域跨入强磁区域。 In the manufacturing process, the difference in magnetic field strength between the two sides of the permanent magnet 510 should be as large as possible to improve the efficiency of the rotor pole 500. In this embodiment, the magnetic field strength of the left side of the permanent magnet 510 can reach 3 to 8 times of the right side. . The permanent magnet 510 is generally oblong and has a length L that is several times greater than the thickness D to obtain a magnetic field of appropriate strength and direction. The thickness D of the permanent magnet 510 is again greater than a multiple of the W width so that the rotor pole 500 can quickly and easily traverse the weak magnetic region into the strong magnetic region during operation.
本发明为拉大永磁体 510两侧磁场强度差异，永磁体 510的端面朝左侧以 直线、 外弧度或内弯度倾斜， 以增加永磁体 510朝左侧的磁力线数量， 端面 的倾斜角度在本实施例中大约为 45°， 当然， 其它适合的角度也可以， 但端面 没有倾斜角度时功效少很多。 永磁体 510的端面在右侧形成一个锐角端， 左 侧形成一钝角端， 由于锐角端所在侧面的长度最长， 因而该角端的磁场强度 也最大。 复合体 520设置在永磁体 510的锐角端所在侧面， 在转子磁极 500 上形成中磁角端 530、 强磁角端 540以及弱磁角端 550。 其中， 中磁角端 530 至强磁角端 540之间的磁力线最多最强， 形成强磁区域 m; 弱磁角端 550至 强磁角端 540的之间的磁力线最少最弱， 形成弱磁区域 B。 定子磁极 600在 本发明中与转子磁极 500是相同的永磁梯度磁极且可互相通用， 只是安装方 法反过来， 强磁区域位于右侧， 而弱磁区域位于左侧。 可以理解的是， 当转 子磁极 500的永磁体 510位于右侧时， 定子磁极 600的永磁体则位于左侧。 以使转子磁极 500能与定子磁极 600强磁区域 Rm与强磁区域 Sm对应，弱磁 区域 RB与弱磁区域 SB对应。 以便转子磁极 500受到定子磁极 600右向左的 正推斥力远大于左向右的推斥力 （反推斥力） ， 进而能够带动转子盘 300做
顺时针方向旋转。 The present invention is a difference in magnetic field strength between the two sides of the permanent magnet 510. The end surface of the permanent magnet 510 is inclined toward the left side by a straight line, an outer arc or an inner camber to increase the number of magnetic lines of the permanent magnet 510 toward the left side. In this embodiment, it is about 45°. Of course, other suitable angles are also possible, but the effect is much less when the end face has no inclination angle. The end face of the permanent magnet 510 forms an acute end on the right side, and an obtuse end on the left side. Since the length of the side on which the acute end is located is the longest, the magnetic field strength at the end is also the largest. The composite body 520 is disposed on the side of the acute-angle end of the permanent magnet 510, and a medium magnetic end 530, a strong magnetic end 540, and a weak magnetic end 550 are formed on the rotor pole 500. Wherein, the magnetic flux between the middle magnetic end 530 and the strong magnetic end 540 is at most strongest, forming a strong magnetic region m ; the magnetic flux between the weak magnetic end 550 and the strong magnetic end 540 is at least the weakest, forming a weak magnetic field Area B. The stator pole 600 is the same permanent magnet gradient pole as the rotor pole 500 in the present invention and is mutually versatile, except that the mounting method is reversed, with the strong magnetic region on the right side and the weak magnetic region on the left side. It can be understood that when the permanent magnet 510 of the rotor pole 500 is located on the right side, the permanent magnet of the stator pole 600 is located on the left side. The rotor magnetic pole 500 can correspond to the stator magnetic pole 600 strong magnetic region Rm and the strong magnetic region Sm, and the weak magnetic region RB corresponds to the weak magnetic region SB. Therefore, the positive repulsive force of the rotor pole 500 from the right to the left of the stator pole 600 is much larger than the repulsive force of the leftward and rightward (reverse repulsion), thereby enabling the rotor disk 300 to be driven. Rotate clockwise.
转子磁极 500和定子磁极 600在安装过程中， 均以厚度方向平行于转轴 200的方式安装，且其在布局过程中充分考虑了磁力线的分布情况。 以转子盘 301-314上的转子磁极组为例，相邻两转子磁极 500之间的距离最好约等于该 两转子磁极 500的有效磁力距离之和。 因为， 若两者距离太近容易产生磁力 线挤压的现象， 造成转子磁极 500的弱磁区域的强度升高， 转子磁极 500所 受反推斥力增加， 从而降低了整个动力机的输出功率； 距离太远了容易产生 磁力线间隙， 不能够很好地维持连续的推斥力。 定子磁极 600 由于分布于在 定子板 401~414的内周缘， 而定子板 401〜414内径仅稍大于转子盘 301~314 的直径， 因而定子磁极 600在定子板 401〜414布置与转子磁极 500类似。 The rotor pole 500 and the stator pole 600 are mounted in such a manner that the thickness direction is parallel to the rotating shaft 200 during the mounting process, and the distribution of the magnetic lines of force is fully considered in the layout process. Taking the rotor pole set on the rotor disk 301-314 as an example, the distance between adjacent rotor poles 500 is preferably approximately equal to the sum of the effective magnetic distances of the two rotor poles 500. Because if the distance between the two is too close, the magnetic field line is squeezed, the strength of the weak magnetic region of the rotor pole 500 is increased, and the reverse repulsive force of the rotor pole 500 is increased, thereby reducing the output power of the entire power machine; Far away, it is easy to generate magnetic line gaps, and it is not able to maintain a continuous repulsive force well. Since the stator poles 600 are distributed on the inner circumferences of the stator plates 401 to 414, and the inner diameters of the stator plates 401 to 414 are only slightly larger than the diameters of the rotor disks 301 to 314, the stator poles 600 are arranged in the stator plates 401 to 414 similarly to the rotor poles 500. .
本发明为了充分利用转子磁极 500和定子磁极 600的磁力线，除了在它们 的布局有所考虑， 在它们之间受力方向上也增加了优化设计。 例如， 为使定 子磁极 600对转子磁极 500的推斥力能够最大限度的做功， 使推斥力的方向 与转子盘 301~314相切； 为此， 将转子磁极 500在安装过程中， 长度方向偏 离转子盘 301 314圆心一定角度， 相应地， 定子磁极 600也偏离同样的角度。 本实施例中， 该角度大约为 15~20°。 当然， 该偏心角度并不局限于 15~20°， 它主要取决于磁力线的分布。 另外， 本发明为了排除相邻转子盘之间的转子 磁极 500的干扰， 提高使用效率， 使相邻转子盘之间的间距大于相应转子磁 极 500之间的有效磁力距离之和。 相应地， 相邻定子板之间的距离也应当大 于相应定子磁极 600之间之间的有效磁力距离之和。 In order to make full use of the magnetic lines of force of the rotor pole 500 and the stator pole 600, the present invention adds an optimized design to the direction of force between them in addition to their layout. For example, in order to maximize the work of the repulsive force of the stator pole 600 on the rotor pole 500, the direction of the repulsive force is tangent to the rotor discs 301-314; for this reason, the rotor pole 500 is longitudinally offset from the rotor during installation. The disk 301 314 is centered at a certain angle, and accordingly, the stator poles 600 are also offset from the same angle. In this embodiment, the angle is approximately 15 to 20 degrees. Of course, the eccentric angle is not limited to 15~20°, and it mainly depends on the distribution of magnetic lines of force. Further, the present invention improves the use efficiency in order to eliminate the interference of the rotor poles 500 between adjacent rotor disks, so that the spacing between adjacent rotor disks is greater than the sum of the effective magnetic distances between the respective rotor poles 500. Accordingly, the distance between adjacent stator plates should also be greater than the sum of the effective magnetic distances between the respective stator poles 600.

图 9示出了与转子盘 301 314中所有位于 85号位置的转子磁极 500发生作 用的定子磁极 600的轴向投影图， 以 1 U至 14U依次表示转子盘 301~314， 则第 8 U至 14U的 85号转子磁极 500在强磁区域 Rm同时受到第 78~84号位置上的 7 个定子磁极 600的强磁区域 Sm的作用力，而产生合成的正推斥力 Fl。第 1 U至 7 U的 85号转子磁极 500在弱磁区域 RB同时受到第 1~7号 7个定子磁极 600的弱磁 区域 SB的作用力， 而产生合成的反推斥力 F2。 由于强磁区域 m的磁场强度高 出弱磁区域 B的磁场强度若干倍，因此推斥力 F1的绝对值大于反推斥力 F2的绝 对值， 由此产生转子盘 301〜314中的所有 85号转子磁极 500所受的联合力 F (F1 一 F2=F) 。 同理， 可以求导出转子盘 301~314中所有 86~90号转子磁极 500所 受的联合力，进而可以求导出整个转子 300所受的总合力，以及总的输出功率。 Figure 9 shows an axial projection of the stator poles 600 acting on all of the rotor poles 500 at position 85 in the rotor disk 301 314, with rotor disks 301-314 in order from 1 U to 14 U, then 8 U to The 14U rotor pole 500 of the 14U is simultaneously subjected to the strong magnetic region Sm of the seven stator poles 600 at positions 78 to 84 in the strong magnetic region Rm, and a resultant positive repulsive force F1 is generated. The No. 85 rotor pole 500 of the 1st U to 7U is subjected to the weak magnetic region SB of the 7th stator poles 600 of the 1st to 7th in the weak magnetic region RB, and the resultant reverse repulsive force F2 is generated. Since the magnetic field strength of the strong magnetic region m is several times higher than the magnetic field strength of the weak magnetic region B, the absolute value of the repulsive force F1 is greater than the absolute value of the anti-repulsion force F2, thereby generating all of the rotors 85 of the rotor disks 301 to 314. The combined force F (F1 - F2 = F) of the magnetic pole 500. Similarly, it is possible to derive the combined forces of all of the rotor poles 500 to 90 of the rotor disks 301 to 314, and to derive the total combined force of the entire rotor 300 and the total output power.
85号位置转子磁极 500所受联合力的计算公式如下： The calculation formula for the combined force of the rotor pole 500 at position 85 is as follows:

πμον2 4πμοΐ2 如图 10至图 13所示， 转子盘 301 314中所有 85〜90号转子磁极 500在旋转 中， 强磁区域 Rm将会与定子板 401〜414中第 1至 84号定子磁极的强磁区域 Sm 逐一相对应， 相互间产生正推斥力； 弱磁区域 RB也会与定子板 401〜414中第 1 至 84号定子磁极的弱磁区域 SB逐一相对应， 相互之间产生反推斥力。 两者形 成合力，在合力的切向力作用下可使转子盘 301〜314旋转，进而带动转轴旋转。 Πμον 2 4πμοΐ 2 As shown in FIGS. 10 to 13, all of the rotor poles 85 to 90 of the rotor disk 301 314 are in rotation, and the strong magnetic region Rm will be the stator magnetic poles No. 1 to 84 of the stator plates 401 to 414. The strong magnetic regions Sm correspond one by one, and a positive repulsive force is generated between each other; the weak magnetic region RB also corresponds to the weak magnetic regions SB of the stator magnetic poles Nos. 1 to 84 of the stator plates 401 to 414 one by one, and opposite to each other Repulsive force. The two form a resultant force to rotate the rotor disks 301 to 314 under the tangential force of the resultant force, thereby driving the rotating shaft to rotate.
本发明中可以通过驱使转子轴向移位，使转子磁极 500和定子磁极 600位 置错开， 以增加定子磁极与转子磁极之间的距离， 使其间的推斥力减弱或消 失， 从而令转子停止转动。 也可以采用机械剎制等方式来实现制动。 In the present invention, by axially displacing the rotor, the rotor pole 500 and the stator pole 600 are staggered to increase the distance between the stator pole and the rotor pole, so that the repulsive force between them is weakened or lost, thereby stopping the rotation of the rotor. Braking can also be achieved by mechanical braking or the like.
图 14示出了本发明另一实施例中的三维永磁推斥动力机， 其与上一实施 例不同点是， 各个定子板上的定子磁极在轴向的投影重合； 而转子盘上的转 子磁极在排列中， 后一转子盘上的转子磁极相对前一转子盘上的转子磁极整 体绕轴心顺时针 /逆时针旋转一定角度， 使转子磁极的轴向投影密集分布于圆 周上。 Figure 14 is a view showing a three-dimensional permanent magnet repulsion power machine according to another embodiment of the present invention, which differs from the previous embodiment in that the stator poles on the respective stator plates are coincident in the axial direction; and the rotor on the rotor disk The magnetic poles are arranged, and the rotor poles on the latter rotor disk rotate clockwise/counterclockwise around the axis with respect to the rotor poles on the previous rotor disk, so that the axial projection of the rotor poles is densely distributed on the circumference.
当然，本发明中转子盘和定子板只是用于承载转子磁极组和定子磁极组一 种优选载体， 但不局限于此。 例如， 可以将转子磁极组安装圆柱状转子上， 而将定子磁极组安装在套设在圆柱状 子***的圆筒状定子的内壁面。 定子 和转子可以是整体式结构， 也可以是组装的结构。 不同磁极之间尺寸和强度 也可以有些不同， 但通过计算、 补偿等方式也可以实现本发明。
Of course, the rotor disk and the stator plate of the present invention are only a preferred carrier for carrying the rotor pole group and the stator pole group, but are not limited thereto. For example, the rotor pole group may be mounted on the cylindrical rotor, and the stator pole group may be mounted on the inner wall surface of the cylindrical stator sheathed on the periphery of the cylindrical shape. The stator and rotor may be of unitary construction or assembled. The size and strength between different poles may also be somewhat different, but the invention may also be implemented by calculation, compensation, and the like.
