Abstract

[Problem] To provide a rotary electric machine and a non-contact power generator that have a good magnetic efficiency and little leak of magnetic flux. [Solution] A rotary electric machine is provided with: a shaft member that is disposed apart from one main surface of a moving body that moves or rotates, wherein the shaft member extends in a direction crossing the rotation/movement direction of the moving body, and rotates in the rotation/movement direction of the moving body; a magnet that is fixed to the periphery of the shaft member and is magnetized in the shaft direction of the shaft member; a rotary body that is disposed apart from the one main surface of the moving body so as to be rotatable around the shaft member, and is disposed in a magnetic path through which the magnetic flux from the magnet passes; and a magnetic flux guide member that is disposed opposite the surface on the side opposite the surface of the magnet facing the rotary body, and is disposed in a magnetic path through which the magnetic flux from the magnet passes. By means of a reactive force acting on the rotary body on the basis of an eddy current generated in a direction hindering a change in the magnetic flux that has passed through the rotary body from the magnet on the one main surface disposed opposite the rotary body, the rotary body rotates around the shaft member in a rotational direction corresponding to the rotation/movement direction of the moving body at a speed that is lower than the rotation/movement speed of the moving body.

Description

回転電機Rotating electric machine
　本発明は、非接触で回転する回転電機に関する。 The present invention relates to a rotating electrical machine that rotates without contact.
　米国特許公開公報２０１４／０１３２１５５号には、非接触で発電する自転車用ダイナモが開示されている。上述した公知文献の自転車用ダイナモは、自転車のホイールの回転軸と直交する方向に延びる回転軸周りに回転する円環状の永久磁石の外周面を、ホイールの外周面に連なる一側面から離隔して配置している。 US Patent Publication No. 2014/0132155 discloses a dynamo for a bicycle that generates power without contact. In the bicycle dynamo of the above-mentioned known document, the outer peripheral surface of an annular permanent magnet that rotates around a rotation axis extending in a direction orthogonal to the rotation axis of the bicycle wheel is separated from one side surface that is continuous with the outer peripheral surface of the wheel. It is arranged.
　永久磁石は、複数の磁極を周方向に並べて配置したものであり、隣接する磁極では、磁化方向が逆になっている。例えば、永久磁石のＮ極がホイールの一側面に対向配置された状態でホイールが回転すると、永久磁石からの磁束の変化を妨げる方向に、ホイールの一側面に渦電流が発生する。この渦電流による磁束と永久磁石からの磁束との反発力および誘引力により、永久磁石は、ホイールの回転方向に回転する。 A permanent magnet has a plurality of magnetic poles arranged in the circumferential direction, and the magnetization directions of the adjacent magnetic poles are reversed. For example, when the wheel rotates with the N pole of the permanent magnet opposed to one side of the wheel, an eddy current is generated on one side of the wheel in a direction that prevents a change in magnetic flux from the permanent magnet. The permanent magnet rotates in the rotation direction of the wheel by the repulsive force and the attractive force of the magnetic flux caused by the eddy current and the magnetic flux from the permanent magnet.
　よって、永久磁石の周囲をコイルで巻回して、永久磁石からの磁束がコイルを鎖交するようにすれば、コイルから誘導電力を取り出すことができる。 Therefore, if the periphery of the permanent magnet is wound with a coil and the magnetic flux from the permanent magnet is linked to the coil, the induction power can be taken out from the coil.
　しかしながら、上述した公知文献に開示された自転車用ダイナモには、以下の課題がある。 However, the dynamo for bicycles disclosed in the above-mentioned publicly known literature has the following problems.
　１．ホイールの一側面に対向配置される永久磁石の面積が限られているため、ホイールと永久磁石との磁気結合量を大きくできない。よって、ホイールに発生する渦電流が小さくなり、永久磁石の回転力も弱くなる。 1. Since the area of the permanent magnet disposed opposite to one side of the wheel is limited, the amount of magnetic coupling between the wheel and the permanent magnet cannot be increased. Therefore, the eddy current generated in the wheel is reduced and the rotational force of the permanent magnet is also reduced.
　２．上述した公知文献では、永久磁石に単一相のコイルを巻回しているが、単一相のコイルでは、コイルが巻回していない部分の永久磁石の磁束を有効利用できないため、鎖交磁束量を増やすことはできない。また、コイルが巻回している部分の永久磁石の極性の向きが、回転軸を中心に対称である場合、常にコイルを鎖交する磁束の総量が打ち消し合ってしまうため、発電できないという問題がある。 2. In the above-mentioned known literature, a single-phase coil is wound around a permanent magnet. However, a single-phase coil cannot effectively use the magnetic flux of a portion of the permanent magnet where the coil is not wound. Can not be increased. In addition, when the direction of the polarity of the permanent magnet around the coil is symmetric about the rotation axis, the total amount of magnetic flux that interlinks the coil always cancels out. .
　３．永久磁石からの磁束は、空気中を伝搬するため、大きな磁気抵抗を受けることになり、磁気効率がよいとはいえない。 3. Since the magnetic flux from the permanent magnet propagates in the air, it receives a large magnetic resistance, and it cannot be said that the magnetic efficiency is good.
　４．ヨークを用いていないため、磁束の漏れが生じやすく、また周囲に導電材料があると、磁路が変化してしまい、発電量に影響を与えてしまうおそれがある。 4. Since the yoke is not used, magnetic flux leakage is likely to occur, and if there is a conductive material around it, the magnetic path may change, which may affect the amount of power generation.
　本発明は、上述した課題に鑑みてなされたものであり、その目的は、磁気効率がよく、磁束の漏れも少ない回転電機および非接触発電機を提供することにある。 The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a rotating electrical machine and a non-contact generator with good magnetic efficiency and less magnetic flux leakage.
　上記の課題を解決するために、本発明の一態様では、回転または移動する移動体の一主面から離隔して配置され、前記移動体の回転または移動方向と交差する方向に延在されて、前記移動体の回転または移動方向に回転する軸部材と、
　前記前記軸部材の周囲に固定され、前記軸部材の軸方向に磁化されている磁石と、
　前記軸部材周りに回転自在で、前記移動体の一主面から離隔して配置され、かつ前記磁石からの磁束が通過する磁路内に配置される回転体と、
　前記磁石の前記回転体に対向する面と反対側の面に対向配置され、前記磁石からの磁束が通過する前記磁路内に配置される磁束ガイド部材と、を備え、
　前記回転体は、前記回転体に対向配置される前記一主面上に前記磁石から前記回転体を通過した磁束の変化を妨げる方向に発生される渦電流に基づいて前記回転体に働く反力により、前記軸部材周りに、前記移動体の回転または移動方向に応じた回転方向に、前記移動体の前記一主面の表面速度よりも遅い周速度で回転する回転電機が提供される。 In order to solve the above-described problem, in one aspect of the present invention, the movable body is arranged apart from one main surface of the rotating or moving mobile body and extends in a direction intersecting the rotational or moving direction of the mobile body. A shaft member rotating in the rotation or movement direction of the moving body;
A magnet fixed around the shaft member and magnetized in the axial direction of the shaft member;
A rotating body that is rotatable around the shaft member, is spaced apart from one main surface of the moving body, and is disposed in a magnetic path through which a magnetic flux from the magnet passes;
A magnetic flux guide member disposed opposite to a surface opposite to the surface facing the rotating body of the magnet and disposed in the magnetic path through which the magnetic flux from the magnet passes,
The rotating body has a reaction force acting on the rotating body based on an eddy current generated in a direction that prevents a change in magnetic flux that has passed through the rotating body from the magnet on the one main surface that is disposed opposite to the rotating body.

In the following embodiments, description will be made centering on characteristic configurations and operations in the rotating electrical machine and the non-contact generator, but the rotating electrical machine and the non-contact generator may have configurations and operations omitted in the following description. However, these omitted configurations and operations are also included in the scope of the present embodiment.
　（第１の実施形態）
　図１は本発明の第１の実施形態による回転電機１の正面図、図２は斜視図である。図１の回転電機１は、軸部材２と、磁石３と、回転体４と、磁束ガイド部材５とを備えている。この回転電機１の軸部材２には、必要に応じて標準電気機械（Standard electric machine）６を接続可能としている。 (First embodiment)
FIG. 1 is a front view of a rotating electrical machine 1 according to the first embodiment of the present invention, and FIG. 2 is a perspective view. The rotating electrical machine 1 in FIG. 1 includes a shaft member 2, a magnet 3, a rotating body 4, and a magnetic flux guide member 5. A standard electric machine 6 can be connected to the shaft member 2 of the rotating electrical machine 1 as necessary.
　軸部材２は、回転または移動する移動体７の一主面７ａから離隔して配置され、移動体７の回転または移動方向と交差する方向に延在されている。軸部材２は、移動体７の回転または移動方向に回転する。 The shaft member 2 is arranged separately from one main surface 7a of the moving body 7 that rotates or moves, and extends in a direction that intersects the rotation or movement direction of the moving body 7. The shaft member 2 rotates in the rotation or movement direction of the moving body 7.
　磁石３は、軸部材２の回転によらず軸部材２の周囲に固定されており、軸部材２の軸方向に磁化されている。図１の例では、磁石３のＮ極３ａとＳ極３ｂを軸部材２の軸方向に配置し、Ｎ極３ａとＳ極３ｂの間に磁石キャリア８を配置している。この磁石キャリア８は、軸部材２の外周面を取り囲むように配置され、磁石キャリア８は軸部材２の回転によらず固定されている。Ｎ極３ａとＳ極３ｂは、磁石キャリア８の対向面にそれぞれ固定されている。なお、磁石３を軸部材２の周囲に固定される構造は、図１に示したものに限定されない。例えば、軸部材２の外周面側に軸受を設けて、この軸受に磁石３を固定した構造でもよいし、磁石キャリア８の形状も様々なものが考えられる。また、図１では、回転体４側にＳ極３ｂを配置し、磁束ガイド部材５側にＮ極３ａを配置しているが、Ｎ極３ａとＳ極３ｂを逆に配置してもよい。 The magnet 3 is fixed around the shaft member 2 regardless of the rotation of the shaft member 2, and is magnetized in the axial direction of the shaft member 2. In the example of FIG. 1, the N pole 3a and the S pole 3b of the magnet 3 are arranged in the axial direction of the shaft member 2, and the magnet carrier 8 is arranged between the N pole 3a and the S pole 3b. The magnet carrier 8 is disposed so as to surround the outer peripheral surface of the shaft member 2, and the magnet carrier 8 is fixed regardless of the rotation of the shaft member 2. The N pole 3 a and the S pole 3 b are respectively fixed to the facing surfaces of the magnet carrier 8. The structure for fixing the magnet 3 around the shaft member 2 is not limited to that shown in FIG. For example, a structure in which a bearing is provided on the outer peripheral surface side of the shaft member 2 and the magnet 3 is fixed to the bearing may be used, and various shapes of the magnet carrier 8 are conceivable. In FIG. 1, the S pole 3b is arranged on the rotating body 4 side and the N pole 3a is arranged on the magnetic flux guide member 5 side. However, the N pole 3a and the S pole 3b may be arranged oppositely.
　回転体４は、軸部材２周りに回転自在で、移動体７の一主面７ａから離隔して配置され、かつ磁石３からの磁束が通過する磁路内に配置されている。 The rotating body 4 is rotatable around the shaft member 2, is disposed apart from one main surface 7 a of the moving body 7, and is disposed in a magnetic path through which the magnetic flux from the magnet 3 passes.
　磁束ガイド部材５は、磁石３の回転体４に対向する面と反対側の面に対向配置されている。磁束ガイド部材５は、磁石３からの磁束が通過する磁路内に配置されている。回転体４と磁束ガイド部材５は、強磁性体で形成するのが望ましい。 The magnetic flux guide member 5 is disposed opposite to the surface of the magnet 3 opposite to the surface facing the rotating body 4. The magnetic flux guide member 5 is disposed in a magnetic path through which the magnetic flux from the magnet 3 passes. The rotating body 4 and the magnetic flux guide member 5 are preferably formed of a ferromagnetic material.
　図１では、正面方向から見て磁石３の左側に回転体４を配置し、磁石３の右側に磁束ガイド部材５を配置しているが、回転体４と磁束ガイド部材５とを逆に配置してもよい。 In FIG. 1, the rotating body 4 is disposed on the left side of the magnet 3 and the magnetic flux guide member 5 is disposed on the right side of the magnet 3 when viewed from the front, but the rotating body 4 and the magnetic flux guide member 5 are disposed in reverse. May be.
　回転体４は、回転体４に対向配置される移動体７の一主面７ａ上に磁石３から回転体４を通過した磁束の変化を妨げる方向に発生される渦電流による磁束と、磁石３からの磁束との反発力および誘引力により、軸部材２周りに移動体７の回転または移動方向に応じた回転方向に、移動体７の一主面７ａの表面速度よりも遅い周速度で回転する。 The rotating body 4 includes a magnetic flux generated by an eddy current generated in a direction that prevents a change in the magnetic flux that has passed through the rotating body 4 from the magnet 3 on one main surface 7a of the moving body 7 that is disposed to face the rotating body 4, and the magnet 3. Rotating at a peripheral speed slower than the surface speed of one main surface 7a of the moving body 7 around the shaft member 2 in the rotation direction according to the rotation or the moving direction by the repulsive force and the attractive force with the magnetic flux from To do.
　軸部材２に接続される標準電気機械６は、オプション機器である。標準電気機械６とは、回転軸の回転を利用して駆動される駆動体である。駆動体は、例えば、軸部材２ととともに回転する不図示のロータと、不図示のステータとを有する。ロータの回転により、負荷を駆動する。駆動体は、より具体的には、発電機や減速機などでもよい。また、駆動体は、回転軸の回転力を利用して空気を圧縮するコンプレッサであってもよい。このように、駆動体には、回転軸の回転力を電気力に変換するものだけでなく、回転軸の回転力を機械力に変換するものも含まれる。 The standard electric machine 6 connected to the shaft member 2 is an optional device. The standard electric machine 6 is a drive body that is driven using the rotation of the rotary shaft. The driving body includes, for example, a rotor (not shown) that rotates together with the shaft member 2 and a stator (not shown). The load is driven by the rotation of the rotor. More specifically, the drive body may be a generator, a speed reducer, or the like. The driver may be a compressor that compresses air by using the rotational force of the rotating shaft. As described above, the driving body includes not only one that converts the rotational force of the rotary shaft into electric force, but also one that converts the rotational force of the rotary shaft into mechanical force.
　図１では、回転体４と磁束ガイド部材５をともに、円板状または円筒状にした例を示しているが、磁束ガイド部材５については、固定であるため、円板状または円筒状以外の形状（例えば、矩形状）でもよい。一方、回転体４は、回転体４の回転角度によらず移動体７の一主面７ａとの距離を均一化させるのが望ましいが、回転体４の形状は種々のものが考えられる。例えば、図３に示すように、軸部材２から径方向に放射状に延びる複数の回転部４ａを有する回転体４であってもよい。 FIG. 1 shows an example in which the rotating body 4 and the magnetic flux guide member 5 are both disk-shaped or cylindrical. However, since the magnetic flux guide member 5 is fixed, other than the disk-shaped or cylindrical shape. The shape (for example, rectangular shape) may be sufficient. On the other hand, the rotating body 4 desirably has a uniform distance from the main surface 7a of the moving body 7 regardless of the rotation angle of the rotating body 4, but various shapes of the rotating body 4 are conceivable. For example, as shown in FIG. 3, the rotating body 4 may have a plurality of rotating portions 4 a that extend radially from the shaft member 2 in the radial direction.
　回転体４は、移動体７の一主面７ａから隙間を隔てて配置されている。同様に、磁束ガイド部材５も、移動体７の一主面７ａから隙間を隔てて配置されている。これらの隙間はエアギャップであり、磁気抵抗と漏れ磁束を増やす要因になる。よって、磁束ガイド部材５と移動体７の一主面７ａとの隙間は、回転体４と移動体７の一主面７ａとの隙間と同程度で、できるだけ小さい方が望ましい。 The rotating body 4 is arranged with a gap from one main surface 7a of the moving body 7. Similarly, the magnetic flux guide member 5 is also arranged with a gap from one main surface 7a of the moving body 7. These gaps are air gaps, which increase the magnetic resistance and leakage flux. Therefore, the gap between the magnetic flux guide member 5 and the one main surface 7a of the moving body 7 is about the same as the gap between the rotating body 4 and the one main surface 7a of the moving body 7, and is preferably as small as possible.
　磁石３のＮ極３ａから出た磁束は、図１の破線矢印線ｙ１に示すように、磁束ガイド部材５の内部を通過して、移動体７の一主面７ａ上に到達する。その後、一主面７ａから回転体４の内部を通過して、Ｓ極３ｂに入る。 The magnetic flux emitted from the N pole 3a of the magnet 3 passes through the inside of the magnetic flux guide member 5 and reaches the main surface 7a of the moving body 7 as shown by the broken arrow line y1 in FIG. Thereafter, the first main surface 7a passes through the inside of the rotating body 4 and enters the S pole 3b.
　このように、磁石３からの磁束は、磁束ガイド部材５の内部、磁束ガイド部材５と移動体７の一主面７ａとの隙間、移動体７の一主面７ａ上、回転体４と移動体７の一主面７ａとの隙間、回転体４の内部を順に通過する。 Thus, the magnetic flux from the magnet 3 moves inside the magnetic flux guide member 5, the gap between the magnetic flux guide member 5 and the one main surface 7 a of the moving body 7, on the one main surface 7 a of the moving body 7, and on the rotating body 4. It passes through the clearance between the main surface 7a of the body 7 and the inside of the rotating body 4 in order.
　回転体４と磁石３との間、および磁束ガイド部材５と磁石３との間にも、それぞれ隙間があり、これらの隙間が大きいと、やはり磁気抵抗と漏れ磁束を増やす要因になる。よって、回転体４と磁束ガイド部材５は、できるだけ磁石３に近づけて配置した方が望ましい。 There are also gaps between the rotating body 4 and the magnet 3 and between the magnetic flux guide member 5 and the magnet 3, and if these gaps are large, it will also increase the magnetic resistance and leakage flux. Therefore, it is desirable to arrange the rotating body 4 and the magnetic flux guide member 5 as close to the magnet 3 as possible.
　このように、本実施形態の回転電機１は、回転体４と磁束ガイド部材５をできるだけ移動体７の一主面７ａに近づけて配置するとともに、回転体４と磁束ガイド部材５をできるだけ磁石３に近づけて配置することで、磁気抵抗と漏れ磁束を最小化することができる。 As described above, the rotating electrical machine 1 of the present embodiment arranges the rotating body 4 and the magnetic flux guide member 5 as close to the main surface 7a of the moving body 7 as possible, and arranges the rotating body 4 and the magnetic flux guide member 5 as much as possible with the magnet 3. By arranging them close to each other, the magnetic resistance and the leakage magnetic flux can be minimized.
　図１の回転電機１では、移動体７が一方向に移動すると、移動体７の一主面７ａ上には、回転体４から移動体７の一主面７ａに向かう磁束の変化を妨げる方向に磁束を発生させるべく、移動体７の一主面７ａ上に渦電流が発生する。この渦電流による磁束と回転体４からの磁束との反発力および誘引力により、回転体４は移動体７の移動方向に応じた方向に回転する。 In the rotating electrical machine 1 of FIG. 1, when the moving body 7 moves in one direction, a direction in which a change in magnetic flux from the rotating body 4 toward the one main surface 7 a of the moving body 7 is prevented on the one main surface 7 a of the moving body 7. An eddy current is generated on one main surface 7a of the moving body 7 in order to generate a magnetic flux. The rotating body 4 rotates in a direction corresponding to the moving direction of the moving body 7 by the repulsive force and the attractive force between the magnetic flux caused by the eddy current and the magnetic flux from the rotating body 4.
　図４は図１の回転体４が回転する原理を説明する図である。図４は軸部材２の軸端方向から見た平面図である。移動体７の一主面７ａ上の回転体４との最近接位置の近傍には、移動体７の移動方向に沿って、電流の向きの異なる２つの渦電流７ｂ、７ｃが発生する。移動体７の移動方向前方に発生する渦電流７ｂは、対向する回転体４からの磁束を強める方向に流れる。また、移動体７の移動方向後方に発生する渦電流７ｃは、対向する回転体４からの磁束を弱める方向に流れる。 FIG. 4 is a diagram for explaining the principle of rotation of the rotating body 4 of FIG. FIG. 4 is a plan view of the shaft member 2 as viewed from the axial end direction. Two eddy currents 7 b and 7 c having different current directions are generated along the moving direction of the moving body 7 in the vicinity of the position closest to the rotating body 4 on the one main surface 7 a of the moving body 7. The eddy current 7b generated in the forward direction of the moving body 7 flows in a direction in which the magnetic flux from the opposing rotating body 4 is strengthened. Further, the eddy current 7c generated behind the moving body 7 in the moving direction flows in a direction in which the magnetic flux from the opposing rotating body 4 is weakened.
　移動体７の移動方向前方では、渦電流７ｂによる磁束と磁石３の磁束との方向が同じになることから、互いに引き寄せ合う誘引力が働く。一方、移動体７の移動方向後方側では、渦電流７ｃによる磁束と磁石３の磁束との方向が逆になることから、互いに反発し合う反発力が働く。回転体４は、移動体７を追いかけるようにして、移動体７の表面速度よりも遅い周速度で回転する。 At the front of the moving body 7 in the moving direction, since the directions of the magnetic flux due to the eddy current 7b and the magnetic flux of the magnet 3 are the same, an attractive force attracting each other works. On the other hand, on the rear side in the moving direction of the moving body 7, since the directions of the magnetic flux due to the eddy current 7c and the magnetic flux of the magnet 3 are reversed, repulsive forces that repel each other work. The rotating body 4 follows the moving body 7 and rotates at a peripheral speed slower than the surface speed of the moving body 7.
　なお、上述した回転体４の回転の原理は、ローレンツ力による反力にて説明することもできる。上述したように、回転体４の回転方向前方からの磁束による発生する渦電流７ｂと、回転体４の回転方向後方からの磁束による発生する渦電流７ｃとは、電流の向きが逆になっていて、回転体４の直下には常に一定方向の電流が流れる。これら渦電流７ｂ、７ｃによる電流は、移動体７が図４の矢印の向き（左方向）に移動する場合には、反対方向（右方向）へのローレンツ力を受ける。よって、これら渦電流７ｂ、７ｃによる磁束を受ける回転体４は、移動体７の移動方向への、ローレンツ力の反力を受けて回転する。よって、回転体４は、移動体７との対抗面同士が同一方向に移動する向きに回転する。 It should be noted that the principle of rotation of the rotating body 4 described above can also be explained by a reaction force due to Lorentz force. As described above, the eddy current 7b generated by the magnetic flux from the front of the rotating body 4 in the rotation direction and the eddy current 7c generated by the magnetic flux from the rear of the rotating body 4 in the rotation direction are opposite in current direction. Thus, a current in a constant direction always flows directly under the rotating body 4. The currents caused by these eddy currents 7b and 7c receive a Lorentz force in the opposite direction (right direction) when the moving body 7 moves in the direction of the arrow (left direction) in FIG. Therefore, the rotating body 4 that receives the magnetic flux generated by the eddy currents 7b and 7c rotates in response to the reaction force of the Lorentz force in the moving direction of the moving body 7. Therefore, the rotating body 4 rotates in the direction in which the opposing surfaces of the moving body 7 move in the same direction.
　このように、図１の回転電機１を移動体７の一主面７ａの近傍に配置した状態で、移動体７を移動または回転させることで、非接触で回転体４および軸部材２を回転させることができる。回転体４および軸部材２の回転力は、移動体７の運動エネルギを抽出したものである。すなわち、本実施形態によれば、図１の回転電機１により、移動体７の運動エネルギを抽出することができる。図１の回転電機１の軸部材２には標準電気機械６を接続することができる。この標準電機機械６は、抽出した移動体７の運動エネルギを電気エネルギや機械エネルギに変換することができる。 As described above, the rotating body 4 and the shaft member 2 are rotated in a non-contact manner by moving or rotating the moving body 7 in a state where the rotating electrical machine 1 of FIG. 1 is disposed in the vicinity of one main surface 7a of the moving body 7. Can be made. The rotational force of the rotating body 4 and the shaft member 2 is obtained by extracting the kinetic energy of the moving body 7. That is, according to this embodiment, the kinetic energy of the moving body 7 can be extracted by the rotating electrical machine 1 of FIG. A standard electric machine 6 can be connected to the shaft member 2 of the rotating electrical machine 1 of FIG. The standard electric machine 6 can convert the extracted kinetic energy of the moving body 7 into electric energy or mechanical energy.
　本実施形態によれば、移動体７からの運動エネルギの抽出と、抽出した運動エネルギの電気エネルギや機械エネルギへの変換とを、回転電機１と標準電気機械６とで別個に行うことができる。すなわち、回転電機１は、移動体７からの運動エネルギの抽出に適した構造に最適化すればよく、また、標準電機機械は、回転電機１で抽出した運動エネルギを電機エネルギや機械エネルギに変換するのに適した構造に最適化すればよい。これにより、回転電機１と標準電気機械６との設計を独立して行うことができ、設計作業が容易になる。 According to the present embodiment, extraction of kinetic energy from the moving body 7 and conversion of the extracted kinetic energy into electrical energy or mechanical energy can be performed separately by the rotating electrical machine 1 and the standard electrical machine 6. . That is, the rotating electrical machine 1 may be optimized to have a structure suitable for extracting kinetic energy from the moving body 7, and the standard electrical machine converts kinetic energy extracted by the rotating electrical machine 1 into electrical energy or mechanical energy. What is necessary is just to optimize to the structure suitable for doing. Thereby, the design of the rotating electrical machine 1 and the standard electric machine 6 can be performed independently, and the design work becomes easy.
　本実施形態による回転電機１は、外部電源を取ることができない場所で、発電機等の標準電気機械６を駆動するために利用できる。移動体７に近接させて、本実施形態による回転電機１を配置することで、外部電源なしで標準電気機械６を駆動することができる。 The rotating electrical machine 1 according to the present embodiment can be used to drive a standard electric machine 6 such as a generator in a place where an external power source cannot be taken. The standard electric machine 6 can be driven without an external power source by disposing the rotating electrical machine 1 according to the present embodiment close to the moving body 7.
　移動体７は、それ自体が移動または回転するものである必要はなく、回転電機１に対して相対的に移動するものであればよい。例えば、本実施形態による回転電機１を列車等の車両に搭載し、この車両を路面やレール上で走行させる場合、路面やレールを移動体７とみなすことができる。すなわち、本実施形態による回転電機１の回転体４を、路面やレール面に近接して配置した状態で、車両を走行させれば、回転体４および軸部材２を回転させることができるため、この回転力を利用して、電気エネルギや機械エネルギを生成することができる。例えば、車両の電装機器類の電源電力として使用することができる。車両以外にも、導電性の移動体があれば、電源配線を引き回さなくても、移動体の近傍で発電し、電力を各種電気機器に供給することができる。 The moving body 7 does not need to be moved or rotated by itself, and may be anything that moves relative to the rotating electrical machine 1. For example, when the rotating electrical machine 1 according to the present embodiment is mounted on a vehicle such as a train and the vehicle is run on a road surface or rail, the road surface or rail can be regarded as the moving body 7. That is, since the rotating body 4 and the shaft member 2 can be rotated by running the vehicle in a state where the rotating body 4 of the rotating electrical machine 1 according to the present embodiment is disposed close to the road surface or the rail surface, Electric energy and mechanical energy can be generated using this rotational force. For example, it can be used as power source power for vehicle electrical equipment. In addition to the vehicle, if there is a conductive moving body, it is possible to generate electric power in the vicinity of the moving body and supply the electric power to various electric devices without routing the power supply wiring.
　このように、第１の実施形態は、移動体７の一主面７ａから離隔して回転体４と磁束ガイド部材５とを配置し、磁石３からの磁束が磁束ガイド部材５と回転体４とを通過する磁路内のエアギャップをできるだけ小さくするため、漏れ磁束と磁気抵抗を最小化でき、磁気効率に優れた回転電機１が得られる。 As described above, in the first embodiment, the rotating body 4 and the magnetic flux guide member 5 are arranged apart from the one main surface 7a of the moving body 7, and the magnetic flux from the magnet 3 is changed to the magnetic flux guide member 5 and the rotating body 4. In order to minimize the air gap in the magnetic path passing through the magnetic path, the leakage magnetic flux and the magnetic resistance can be minimized, and the rotating electrical machine 1 having excellent magnetic efficiency can be obtained.
　（第２の実施形態）
　第２の実施形態は、磁束ガイド部材５を回転させるものである。 (Second Embodiment)
In the second embodiment, the magnetic flux guide member 5 is rotated.
　図５は本発明の第２の実施形態による回転電機１の正面図、図６は斜視図である。図６の回転電機１は、磁束ガイド部材５が軸部材２周りに回転自在であることが第１の実施形態とは異なっており、その他の構成は同じである。 FIG. 5 is a front view of the rotating electrical machine 1 according to the second embodiment of the present invention, and FIG. 6 is a perspective view. The rotating electrical machine 1 of FIG. 6 is different from the first embodiment in that the magnetic flux guide member 5 is rotatable around the shaft member 2, and the other configurations are the same.
　回転体４と磁束ガイド部材５は、ともに軸部材２周りに回転自在であるが、回転体４と磁束ガイド部材５の外形サイズは必ずしも同一でなくてもよい。ただし、回転体４と磁束ガイド部材５はともに軸部材２の周りを回転するため、軸部材２の延在方向が移動体７の一主面方向７ａに平行な場合は、回転体４と磁束ガイド部材５の外径サイズが異なると、外径サイズが小さい方における移動体７の一主面７ａとの隙間が大きくなってしまう。よって、軸部材２の延在方向が移動体７の一主面方向７ａに平行な場合は、回転体４と磁束ガイド部材５の外径サイズを同じにする方が望ましい。 Both the rotating body 4 and the magnetic flux guide member 5 are rotatable around the shaft member 2, but the outer sizes of the rotating body 4 and the magnetic flux guide member 5 are not necessarily the same. However, since both the rotating body 4 and the magnetic flux guide member 5 rotate around the shaft member 2, when the extending direction of the shaft member 2 is parallel to the one principal surface direction 7a of the moving body 7, the rotating body 4 and the magnetic flux When the outer diameter size of the guide member 5 is different, the gap between the main surface 7a of the moving body 7 on the smaller outer diameter size is increased. Therefore, when the extending direction of the shaft member 2 is parallel to the main surface direction 7a of the moving body 7, it is desirable that the outer diameter size of the rotating body 4 and the magnetic flux guide member 5 be the same.
　なお、軸部材２の延在方向は、移動体７の一主面７ａ方向に平行でなくてもよい。例えば図７は軸部材２の延在方向を移動体７の一主面７ａ方向から傾けて配置した例を示す図である。この場合、軸部材２の周りを回転する回転体４および磁束ガイド部材５の径サイズを同じにすると、磁束ガイド部材５と移動体７の一主面７ａとの隙間がより大きくなってしまう。よって、軸部材２の延在方向と移動体７の一主面７ａとの傾斜角度に応じて、回転体４と磁束ガイド部材５との径サイズを相違させて、移動体７の一主面７ａとの隙間が回転体４と磁束ガイド部材５でほぼ同じになるようにしてもよい。 In addition, the extending direction of the shaft member 2 may not be parallel to the direction of the one main surface 7a of the moving body 7. For example, FIG. 7 is a diagram illustrating an example in which the extending direction of the shaft member 2 is arranged to be inclined from the direction of the one main surface 7a of the moving body 7. In this case, if the diameters of the rotating body 4 and the magnetic flux guide member 5 rotating around the shaft member 2 are the same, the gap between the magnetic flux guide member 5 and the one main surface 7a of the moving body 7 becomes larger. Therefore, depending on the inclination angle between the extending direction of the shaft member 2 and the one main surface 7a of the moving body 7, the diameters of the rotating body 4 and the magnetic flux guide member 5 are made different, so that the one main surface of the moving body 7 The gap between the rotating body 4 and the magnetic flux guide member 5 may be substantially the same.
　回転体４と磁束ガイド部材５の双方とも、移動体７の移動に伴って、移動体７の一主面７ａ上に渦電流を発生させる。すなわち、移動体７の一主面７ａ上には、回転体４の直下と磁束ガイド部材５の直下とに、それぞれ渦電流が発生する。これら渦電流は、回転体４および磁束ガイド部材５を、移動体７の移動方向に応じた方向に回転させる。よって、第１の実施形態よりも、軸部材２を回転させる回転力を高めることができる。すなわち、第２の実施形態では、第１の実施形態よりも、移動体７の運動エネルギをより効率よく抽出でき、標準電気機械６にて得られる電気エネルギや機械エネルギも大きくできる。 Both the rotating body 4 and the magnetic flux guide member 5 generate eddy currents on one main surface 7a of the moving body 7 as the moving body 7 moves. That is, eddy currents are generated on the main surface 7 a of the moving body 7 immediately below the rotating body 4 and immediately below the magnetic flux guide member 5. These eddy currents rotate the rotating body 4 and the magnetic flux guide member 5 in a direction corresponding to the moving direction of the moving body 7. Therefore, the rotational force for rotating the shaft member 2 can be increased as compared with the first embodiment. That is, in the second embodiment, the kinetic energy of the moving body 7 can be extracted more efficiently than in the first embodiment, and the electric energy and mechanical energy obtained by the standard electric machine 6 can be increased.
　このように、第２の実施形態では、回転体４だけでなく、磁束ガイド部材５も軸部材２周りに回転自在とするため、移動体７の移動方向に応じて、回転体４と磁束ガイド部材５をともに回転させて、移動体７の運動エネルギをより多く抽出することができる。 As described above, in the second embodiment, not only the rotating body 4 but also the magnetic flux guide member 5 is rotatable around the shaft member 2, so that the rotating body 4 and the magnetic flux guide depend on the moving direction of the moving body 7. By rotating the members 5 together, more kinetic energy of the moving body 7 can be extracted.
　（第３の実施形態）
　第３の実施形態は、回転体４、磁石３および磁束ガイド部材５を密着配置したものである。 (Third embodiment)
In the third embodiment, the rotating body 4, the magnet 3, and the magnetic flux guide member 5 are arranged in close contact with each other.
　図８は本発明の第３の実施形態による回転電機１の正面図である。図８の回転電機１は、回転体４、磁石３および磁束ガイド部材５を密着配置した点で、図５の回転電機１とは異なっている。 FIG. 8 is a front view of the rotating electrical machine 1 according to the third embodiment of the present invention. The rotating electrical machine 1 of FIG. 8 differs from the rotating electrical machine 1 of FIG. 5 in that the rotating body 4, the magnet 3 and the magnetic flux guide member 5 are arranged in close contact.
　図８の回転体４、磁石３および磁束ガイド部材５はいずれも、軸部材２とともに回転する。よって、磁石３を固定化させるための磁石キャリアは不要となる。 8 all rotate together with the shaft member 2. The rotating body 4, the magnet 3 and the magnetic flux guide member 5 in FIG. Therefore, a magnet carrier for fixing the magnet 3 is not necessary.
　図８の回転電機１では、回転体４と磁石３との間に隙間がなく、磁束ガイド部材５と磁石３との間にも隙間がないため、磁石３からの磁束が通過する磁路内での隙間は、回転体４および磁束ガイド部材５と移動体７の一主面７ａとの間だけになり、磁路内の磁気抵抗をより低減でき、磁気効率が向上する。 In the rotating electrical machine 1 of FIG. 8, there is no gap between the rotating body 4 and the magnet 3, and there is no gap between the magnetic flux guide member 5 and the magnet 3, so that the magnetic flux from the magnet 3 passes through the magnetic path. The gap at is only between the rotating body 4 and the magnetic flux guide member 5 and one main surface 7a of the moving body 7, and the magnetic resistance in the magnetic path can be further reduced, and the magnetic efficiency is improved.
　回転体４と磁束ガイド部材５は、磁石３からの磁束を通しやすい透磁率の高い材料（例えば、強磁性体）で形成されている。回転体４と磁束ガイド部材５は、全く同じ材料で形成してもよいし、別個の材料で形成してもよい。 The rotating body 4 and the magnetic flux guide member 5 are formed of a material having a high magnetic permeability (for example, a ferromagnetic material) through which the magnetic flux from the magnet 3 can easily pass. The rotating body 4 and the magnetic flux guide member 5 may be formed of the same material, or may be formed of separate materials.
　このように、第３の実施形態では、回転体４、磁石３および磁束ガイド部材５を密着配置するため、回転体４および磁束ガイド部材５と磁石３との間に隙間がなくなり、磁気効率がよくなる。 As described above, in the third embodiment, the rotating body 4, the magnet 3, and the magnetic flux guide member 5 are disposed in close contact with each other, so that there is no gap between the rotating body 4, the magnetic flux guide member 5, and the magnet 3. Get better.
　上述した第１～第３の実施形態において、磁石３は、永久磁石でもよいし、電磁石でもよい。 In the first to third embodiments described above, the magnet 3 may be a permanent magnet or an electromagnet.
