Description
本発明は発電機の技術に関し、詳しくは、コイルと永久磁石を周方向又は軸方向へ連続して繰り返し備える連設式の構成を採用することで小さな力で稼働できる連設式発電装置に関する。 The present invention relates to a generator technology, and more particularly, to a continuous power generator that can be operated with a small force by adopting a continuous structure in which a coil and a permanent magnet are continuously provided in a circumferential direction or an axial direction.
近年、エネルギー問題への関心が高まり、再生エネルギーなどの開発、事業化の動きも活発である。また、エネルギーの効率的使用の観点から、磁石の性能の向上改善も進んでおり、希土類磁石を代表するネオジム磁石のように、残留磁束密度と保持力の大きな永久磁石が登場したことから、これらを用いた動力装置や発電機などに関する技術が様々提案されている。 In recent years, interest in energy issues has increased, and development and commercialization of renewable energy have been active. In addition, from the viewpoint of efficient use of energy, the improvement and improvement of magnet performance is also progressing, and permanent magnets with large residual magnetic flux density and coercive force such as neodymium magnets that represent rare earth magnets have appeared. Various technologies related to power devices and power generators using the power generator have been proposed.
また、地球環境問題やエネルギー枯渇問題への対応として、風力発電システムなどの自然エネルギーを利用して発電機を駆動するものが急激に増えてきている。これらに用いられる発電システムの多くは永久磁石とコイルを使用した発電機が使用されているが、コア付きの永久磁石式発電機の場合であると、発電電圧は高いものの、永久磁石とステータコアとの吸引力に起因するコギングトルクや、コア内で発生する渦電流等の鉄損による制動によって、風車やタービン等の起動性を著しく低下させる問題があり、コギングトルクが風車等の失速トルクよりも低いか、若しくはコギングトルクが発生しない発電機が必要となる。 In addition, as a response to global environmental problems and energy depletion problems, the number of generators that use natural energy such as wind power generation systems is rapidly increasing. Many of the power generation systems used for these use a generator using a permanent magnet and a coil. In the case of a permanent magnet generator with a core, although the generated voltage is high, the permanent magnet and the stator core There is a problem that the startability of the windmill, turbine, etc. is significantly reduced by cogging torque due to the attractive force of the motor and braking due to iron loss such as eddy current generated in the core. A generator that is low or does not generate cogging torque is required.
一方、コアを必要としない所謂コアレス発電装置の機場合では始動性が非常に良く、回転数とともに増加する鉄損も存在せず、風力発電等の発電装置としては適しているといえる。しかしながら、コア付きに比べて発電電圧が低く、充分な電力を得ることが難しいという欠点がある。そこで上記のコアレス発電機装置の長所を得ながら発電量を高めるために、コイルと永久磁石との配置をどのような構成とすれば良いかという問題は、発電装置の技術が発達した今日においても未だに改良の余地を残している。 On the other hand, in the case of a so-called coreless power generator that does not require a core, the startability is very good and there is no iron loss that increases with the number of revolutions, so that it can be said to be suitable as a power generator for wind power generation or the like. However, there is a drawback that the generated voltage is lower than that with a core and it is difficult to obtain sufficient power. Therefore, in order to increase the amount of power generation while obtaining the advantages of the above coreless generator device, the problem of how to arrange the coil and the permanent magnet is a problem even today when the technology of the power generator has been developed. There is still room for improvement.
そこで、本願の発明者は、前記の問題点に鑑み、効率よく大きな有効電力を取り出せる発電装置の開発を課題として、磁気回路を周方向や軸方向へ連続的に繰り返して配置し、これを多層化するなどのレイアウトに着目し、本願発明を完成させたものである。 In view of the above problems, the inventor of the present application has arranged the magnetic circuit continuously and repeatedly in the circumferential direction and the axial direction for the purpose of developing a power generating device that can efficiently extract a large effective power. The present invention has been completed by paying attention to a layout such as
また、本願発明者以外にも上記の問題点を解決しようと、種々の技術が提案されている。例えば、発明の名称を「永久磁石とコイルを用いた回転型発電機」とする先行技術が公開され公知技術となっている。係る技術は、解決手段を、内側の一部または全部が円板状にくり抜かれた形状の円環体、および円環体の内周面から一定間隙を有して、円環体内側の円板状空洞に入り込んだ円板体を含み、複数の永久磁石が円環体の内部に配置、固定され、永久磁石の一方の磁極（Ａ極とする）が、円板体の外周面と対向するように配置され、複数の永久磁石が円板体の内部に配置、固定され、永久磁石の一方の磁極（Ｂ極とする）が、円環体の内周面と対向するように配置され、Ａ極とＢ極は逆極であり、Ａ極およびＢ極の間に導線を巻いたコイルが配置され、コイルの軸の方向は半径方向であり、円環体または円板体は、それぞれ円板体または円環体に対して回転することにより、コイルに誘導電圧を発生させて発電することを特徴とする技術である（特許文献１を参照）。 In addition to the inventors of the present application, various techniques have been proposed to solve the above problems. For example, the prior art with the name of the invention “rotary generator using a permanent magnet and a coil” is publicly known. In the technology, the solving means includes a torus having a shape in which a part or all of the inside is hollowed out in a disc shape, and a constant gap from the inner peripheral surface of the torus. A disk body that has entered a plate-like cavity is included, and a plurality of permanent magnets are arranged and fixed inside the annular body, and one magnetic pole (A pole) of the permanent magnet faces the outer peripheral surface of the disk body. The plurality of permanent magnets are arranged and fixed inside the disc body, and one magnetic pole (referred to as B pole) of the permanent magnet is arranged to face the inner peripheral surface of the torus. , A pole and B pole are opposite poles, a coil with a conducting wire wound between A pole and B pole is disposed, the axial direction of the coil is radial direction, This is a technique characterized by generating an induced voltage in a coil by rotating with respect to a disk or an annular body ( See Patent Document 1).
係る先行技術では、一組の円盤体と円環体によるものであることから、与えられる回転が小さくても、有効電力の取り出しは可能と考えられる。しかしながら、誘導電圧を発生させる磁石がコイルと周方向に一列という制限の中では配置数に限界があり、大きな電力の発生を得る発電機には向かないものといえ、前記課題を全て解決するには至っていない。 In such prior art, since it is based on a pair of discs and annulus, it is considered that effective power can be taken out even if a given rotation is small. However, there is a limit to the number of magnets that can generate an induced voltage in a line with the coil in the circumferential direction, and it is not suitable for a generator that can generate a large amount of power. Has not reached.
特許文献２によれば、連設式発電装置により、本発明と同様にコギングトルクを抑制し、コアレス発電を行うものが掲載されているが、位相が同一であり、コギングトルクの抑制を行うものとは言い切れず、前記問題の解決には至っていない。 According to Patent Document 2, a cogeneration torque generator that suppresses cogging torque and performs coreless power generation in the same manner as in the present invention is described using a continuous power generator, but the phase is the same and cogging torque is suppressed. However, the problem has not been solved.
本発明者はそれらの問題を解決しようと、回転する円板における磁石の対向位置に着目し、「連設式発電装置」の提案に至るものである。 In order to solve these problems, the present inventor focuses on the opposing position of the magnets in the rotating disk and leads to the proposal of a “continuous power generator”.
本発明は、回転力を電力に変換する発電装置において、コアレス化によりコギングトルクを低減させると共に、回転開始時の発電に係る起動トルクを抑制し、発電効率及び配置構成の自由度を向上させることで総合的に十分な発電量を確保する発電装置を提供するものである。 The present invention reduces the cogging torque by reducing the cogging torque in the power generation device that converts the rotational force into electric power, suppresses the starting torque related to the power generation at the start of rotation, and improves the power generation efficiency and the degree of freedom of the arrangement configuration. Therefore, it is intended to provide a power generation device that ensures a sufficient amount of power generation comprehensively.

本発明に係る連設式発電装置１は、永久磁石４０の両磁極が回転軸と平行方向若しくは、回転軸１０の中心から円周方向に向かう直線上に複数配置されることを最大の特徴とする。
以下、図面に基づいて詳細に説明をする。
The continuous power generator 1 according to the present invention is characterized in that a plurality of both magnetic poles of the permanent magnet 40 are arranged in a direction parallel to the rotation axis or on a straight line from the center of the rotation axis 10 to the circumferential direction. To do.
Hereinafter, it demonstrates in detail based on drawing.
図１は、本発明に係る連設式発電装置１の概要説明図であり、本発明は基本的構成部材として永久磁石４０とコイル２２・２３を同一円周上に設置し、該設置した永久磁石４０側を回転自在としたものである。明細書並びに特許請求の範囲に記載した構成では、コイル２２・２３を固定する固定円状基盤２０は固定され、他方、永久磁石４０を備えた回転円状基板３０と回転環状基板３１は回転する構成を例示したものである。係る構成を採用した場合、回転する永久磁石４０の重量により慣性力が高まるという効果が期待できる。 FIG. 1 is a schematic explanatory view of a continuous power generator 1 according to the present invention. In the present invention, a permanent magnet 40 and coils 22 and 23 are installed on the same circumference as basic components, and the installed permanent The magnet 40 side is rotatable. In the configuration described in the specification and claims, the fixed circular base 20 for fixing the coils 22 and 23 is fixed, while the rotating circular substrate 30 and the rotating annular substrate 31 having the permanent magnets 40 rotate. The configuration is exemplified. When such a configuration is employed, an effect of increasing the inertial force due to the weight of the rotating permanent magnet 40 can be expected.
他方で、係る構成を逆にすることも有効である。即ち、コイル２２・２３を固定する固定円状基盤２０を回転させ、他方、永久磁石４０を備えた回転円状基板３０と回転環状基板３１を固定する構成も有用である。係る構成を採用した場合には回転物が軽量なコイル２２・２３であることから小さな力による稼働が期待できる。 On the other hand, it is also effective to reverse the configuration. That is, a configuration in which the fixed circular base plate 20 for fixing the coils 22 and 23 is rotated and the rotary circular substrate 30 provided with the permanent magnet 40 and the rotary annular substrate 31 are fixed is also useful. When such a configuration is adopted, since the rotating object is the lightweight coils 22 and 23, operation with a small force can be expected.
また、図１に示される放射状に向かって直線状に配置される電磁回路は、小さな永久磁石４０と小さなコイル２２・２３から成るため、個々の該電磁回路から発生する誘導電流は小さなものとなるが、本願発明の構成の特徴である電磁回路を連続して拡張していく構成から得られる誘導電流の総和はその回路の数に比例して大きくなる。さらにコアレス化による大きなメリットとしてコギングトルクの発生を解消できるという点がある。なお、係るコギングトルクの特性を抑制することが出来れば、回転抵抗が少なくなり、低速から回転を安定させることができる。他方、コアレス化することのデメリットとしては大きな電力を取り出すことができないという点がある。この様なメリットデメリットを踏まえた上で使用目的に応じて永久磁石４０とコイル２２・２３の配置構成を拡張し、小さな容量の発電装置から大きな発電装置まで対応可能としている。 Further, since the electromagnetic circuit arranged linearly in the radial direction shown in FIG. 1 includes the small permanent magnet 40 and the small coils 22 and 23, the induced current generated from each of the electromagnetic circuits is small. However, the sum of the induced currents obtained from the configuration in which the electromagnetic circuit, which is a feature of the configuration of the present invention, is continuously expanded increases in proportion to the number of the circuits. Furthermore, a major advantage of the coreless is that the generation of cogging torque can be eliminated. If the characteristics of the cogging torque can be suppressed, the rotational resistance can be reduced and the rotation can be stabilized from a low speed. On the other hand, the disadvantage of making it coreless is that it cannot extract a large amount of power. In consideration of such merits and demerits, the arrangement of the permanent magnets 40 and the coils 22 and 23 is expanded according to the purpose of use, so that it is possible to cope with power generators with small capacities and large power generators.
図２は、本発明に係る連設式発電装置１の全体構成を示す全体説明斜視図である。回転軸１０と、複数の永久磁石４０と、複数のコイル２２・２３と、回転円状基板３０と、固定円状基板２０と、回転環状基板３１と、から構成されることを示しており、回転円状基板３０と回転環状基板３１はいずれも前記回転軸１０に固定されて該回転軸１０と共に回転し、前記永久磁石４０を中心から等分される放射方向へ向かって極性を交互に変えながら連続して配置する基板であり、前記固定円状基板２０は、前記回転軸１０に固定された前記回転円状基板３０と前記回転環状基板３１を回転自在となるように軸支し、中心から周方向に等分して設けられるコイル基台２１に前記複数のコイル２２・２３を配置するための基板であり、前記回転円状基板３０と前記回転環状基板３１は、前記固定円状基板２０に対して外部から回転力を与えられることによって誘導電流を発生させて発電する構成である。 FIG. 2 is an overall explanatory perspective view showing the overall configuration of the continuous power generator 1 according to the present invention. It shows that the rotating shaft 10, the plurality of permanent magnets 40, the plurality of coils 22, 23, the rotating circular substrate 30, the fixed circular substrate 20, and the rotating annular substrate 31 are configured. Both the rotating circular substrate 30 and the rotating annular substrate 31 are fixed to the rotating shaft 10 and rotate together with the rotating shaft 10, and the polarities are alternately changed in the radial direction equally divided from the center of the permanent magnet 40. However, the fixed circular substrate 20 pivotally supports the rotating circular substrate 30 fixed to the rotating shaft 10 and the rotating annular substrate 31 so as to be rotatable. Is a substrate for disposing the plurality of coils 22 and 23 on a coil base 21 that is equally divided in the circumferential direction, and the rotating circular substrate 30 and the rotating annular substrate 31 are the fixed circular substrate. Rotate from outside to 20 It is configured to generate power by generating induced current by given.
前記永久磁石４０には、希土類永久磁石を用いることが望ましく、特にネオジム磁石は、強磁性特性を有していることから発電に適しているといえる。但し、ネオジム磁石は、熱に弱く、温度上昇により磁力が低下すると磁性特性が戻らないため、サマリウムコバルト磁石のように高温下での条件下では耐えられる磁石を用いる等、温度環境等に応じた磁石材料を適宜選択することが望ましい。 The permanent magnet 40 is preferably a rare earth permanent magnet, and in particular, a neodymium magnet is suitable for power generation because it has ferromagnetic properties. However, neodymium magnets are vulnerable to heat, and magnetic properties do not return when the magnetic force decreases due to temperature rise, so depending on the temperature environment, such as using magnets that can withstand conditions under high temperatures, such as samarium cobalt magnets It is desirable to select a magnet material as appropriate.
コイル２２・２３はコイル基台２１によって固定され、コイル２２・２３の周囲を回転する永久磁石４０の両極間に生ずる電磁誘導によって発生する交流電流を得るためのものであり、本願発明ではコギングトルクの発生を防止することを目的とするため、コアレスコイルを採用することとしている。但し、コアレスにする目的は小さな回転力でも電力を発生させるためであり、コギングトルクによる回転負荷を十分に凌駕する回転力を供給することが可能であるならば、発電能力ならびに放熱特性にも配慮したコア材料を用いることも有用である。 The coils 22 and 23 are fixed by the coil base 21 and are for obtaining an alternating current generated by electromagnetic induction generated between both poles of the permanent magnet 40 rotating around the coils 22 and 23. In the present invention, the cogging torque is obtained. In order to prevent the occurrence of this, a coreless coil is employed. However, the purpose of making it coreless is to generate electric power even with a small rotational force. If it is possible to supply a rotational force sufficiently surpassing the rotational load due to cogging torque, the power generation capacity and heat dissipation characteristics are also considered. It is also useful to use a core material that has been prepared.
図３は、本発明に係る連設式発電装置１の内部構造説明図である。図３は、最も単純な構成を示し、回転円状基板３０、固定環状基板２０及び回転環状基板３１が配置された構成を示す。なお、図６には係る構成を更に周方向に複数繰り返して配置することにより、周速度も向上し、これらを総合して低速回転から高速回転まで広い回転領域で効率よく電流出力を得ることが可能となることを示している。 FIG. 3 is an explanatory diagram of the internal structure of the continuous power generator 1 according to the present invention. FIG. 3 shows the simplest configuration, in which a rotating circular substrate 30, a fixed annular substrate 20, and a rotating annular substrate 31 are arranged. It should be noted that the peripheral speed is also improved by repeatedly arranging the configuration shown in FIG. 6 in the circumferential direction, and by combining these, current output can be efficiently obtained in a wide rotation range from low speed rotation to high speed rotation. It shows that it becomes possible.
図４は、本発明に係る連設式発電装置１の電磁回路を説明する説明図であり、図４（ａ）では一系統の電磁回路から誘導電流を得る構成を示し、図４（ｂ）では、環状へ拡張することで、配置スペースに余裕スペースが出る場合には二系統以上の複数系統とすることで、コアレスによる電力不足を補う構成を示している。本発明の特徴としてコアレス化することで小さな外力での発電を可能とする一方で、発電量の確保のため、環状連設による発電の拡張機能のための電磁回路に工夫することが望ましいところ、図４（ａ）に示すように、個々の電磁回路は回転軸１０の中心から同一円周上に環状に一列に並ぶ構成を基本としつつ、図４（ｂ）に示すように、コイルのピッチ間にスペース的な余裕が生まれる回転環状基板３１や拡張用回転環状基板３２においては、誘導電流の発生を増加させるため異なる系統の電磁回路としての第一系統２４と、第二系統２５のそれぞれの電磁回路から電力の供給を受けることができるという連設型とした特徴を発揮しうる構成である。 FIG. 4 is an explanatory view for explaining the electromagnetic circuit of the continuous power generator 1 according to the present invention. FIG. 4 (a) shows a configuration for obtaining an induced current from one system of electromagnetic circuit, and FIG. 4 (b). Then, by extending to a ring shape, when there is a marginal space in the arrangement space, a configuration that compensates for power shortage due to corelessness by using two or more systems is shown. While it is possible to generate power with a small external force by making it coreless as a feature of the present invention, it is desirable to devise an electromagnetic circuit for expansion function of power generation by annular connection in order to secure the amount of power generation, As shown in FIG. 4 (a), the individual electromagnetic circuits are basically arranged in a line on the same circumference from the center of the rotating shaft 10, and as shown in FIG. In the rotating annular substrate 31 and the expanding rotating annular substrate 32 in which a space is created between the first system 24 and the second system 25 as electromagnetic systems of different systems in order to increase the generation of induced currents. This is a configuration that can exhibit the characteristics of a continuous type that can be supplied with electric power from an electromagnetic circuit.
図５は、本発明に係る連設式発電装置１の電磁回路を上記の通り二系統備える場合の作動状態説明図である。但し、図面上では第一系統２４と第二系統２５の関係が見えにくいため、第一系統２４に係るコイルにはコイル基台２１を示し、別系統となる第二系統２５に係るコイル２２・２３については、コイル基台２１を示さずにコイルのみで現した。この様にコイル２２・２３同士の距離を短くして周方向に多数配列することにより一周あたりに発生させる誘電電流の数を増加させ、より大きな発電を可能とする構成である。 FIG. 5 is an explanatory view of the operating state when the electromagnetic circuit of the continuous power generator 1 according to the present invention is provided with two systems as described above. However, since it is difficult to see the relationship between the first system 24 and the second system 25 on the drawing, the coil base 21 is shown in the coil related to the first system 24 and the coil 22. About 23, it showed only with the coil, without showing the coil base 21. In this way, by arranging a large number in the circumferential direction by shortening the distance between the coils 22, 23, the number of dielectric currents generated per round is increased, thereby enabling a larger power generation.
図６は、本発明に係る連設式発電装置１の連設方式を円周方向に拡張する場合の実施例説明図である。なお、図６には、内側に４組の永久磁石４０と、該永久磁石４０に電磁誘導による発電をさせるためのコイル２２・２３を外側に配置し、更にその外側に１２組の電磁回路が設けられる構成の連設式発電装置１が示されている。図６に示すように、環状に拡張させるために拡張用回転環状基板３２を設けて同一円周上に配置されるピッチをより細かくし多極化することにより、大きな電流出力を得ることが可能となる。例えば、図面には示していないが、図６の外周にもう一組の固定円状基板２０と拡張用回転環状基板３２を設ける構成では、図面に示した各永久磁石４０間に皿部２つの電磁回路を設けると３６組を設けることが出来るため、大きな拡張が可能である。
FIG. 6 is an explanatory diagram of an embodiment in the case where the continuous system of the continuous power generator 1 according to the present invention is extended in the circumferential direction. In FIG. 6, four sets of permanent magnets 40 and coils 22 and 23 for causing the permanent magnets 40 to generate electric power by electromagnetic induction are arranged on the outside, and 12 sets of electromagnetic circuits are arranged on the outside. A continuous power generator 1 having a configuration to be provided is shown. As shown in FIG. 6, it is possible to obtain a large current output by providing an expanding rotary annular substrate 32 for expanding in an annular shape and making the pitch arranged on the same circumference finer and multipolar. . For example, although not shown in the drawing, in the configuration in which another set of fixed circular substrate 20 and expansion rotary annular substrate 32 are provided on the outer periphery of FIG. 6, two plates are provided between each permanent magnet 40 shown in the drawing. If an electromagnetic circuit is provided, 36 sets can be provided, so that large expansion is possible.
図７は、本発明に係る連設式発電装置１の連設方式を回転軸方向に拡張する場合の実施例説明図であり、回転軸１０と、複数の永久磁石４０と、複数のコイル５１・５２と、回転基台６０と、筒状固定基台５０と、から構成される発電装置の実施例であって、前記回転基台６０は、前記回転軸１０に固定されて該回転軸１０と共に回転し前記複数の永久磁石４０の両磁極を結ぶ直線を前記回転軸１０と平行に配置させるための基台であり、前記筒状固定基台５０は、前記回転軸１０に固定された前記回転基台６０を回転自在となるように軸支し、前記複数の回転基台６０の間に設けられるコイル基台２１に前記複数のコイル５１・５２を配置するための基台であり、前記回転基台６０は、前記筒状固定基台５０に対して外部から回転力を与えられることによって誘導電流を発生させて発電する構成を示している。 FIG. 7 is an explanatory diagram of an embodiment in the case where the continuous system of the continuous power generation apparatus 1 according to the present invention is extended in the direction of the rotation axis. The rotation axis 10, the plurality of permanent magnets 40, and the plurality of coils 51 are illustrated. 52 is an embodiment of a power generation device including a rotation base 60, and a cylindrical fixed base 50, and the rotation base 60 is fixed to the rotation shaft 10 and the rotation shaft 10 And the cylindrical fixed base 50 is fixed to the rotary shaft 10. The straight base connecting the magnetic poles of the plurality of permanent magnets 40 is arranged in parallel with the rotary shaft 10. A base for pivotally supporting the rotary base 60 so as to be rotatable, and disposing the plurality of coils 51 and 52 on a coil base 21 provided between the plurality of rotary bases 60, The rotary base 60 gives a rotational force to the cylindrical fixed base 50 from the outside.

図７の構成を採用することにより、風力発電に用いる場合等、風力発電機の支柱内部に垂直方向に本発明に係る連設式発電装置１を内設することにより、送電に係る回転部分を被覆し故障しにくい効果を発揮し得る。また、係る構成を採用した場合、連続的に繰り返されるコイル２２・２３と永久磁石４０の磁器回路にはコアレスコイルとすることによりコギングトルクの発生を抑制し、軽い力で稼働することが可能である。 By adopting the configuration of FIG. 7, for example, when using for wind power generation, by installing the continuous power generator 1 according to the present invention in the vertical direction inside the column of the wind power generator, the rotating portion related to power transmission can be reduced. It can be effective to cover and not easily break down. In addition, when such a configuration is adopted, it is possible to suppress the generation of cogging torque by using a coreless coil in the magnetic circuit of the continuously repetitive coils 22 and 23 and the permanent magnet 40, and to operate with a light force. is there.
図８は、本発明に係る連設式発電装置１の連設方式を円周方向並びに回転軸方向の何れにも拡張する場合の実施例説明図である。図８に示すように、回転軸１０と共に回転し前記複数の永久磁石４０の両磁極を結ぶ直線が前記回転軸１０と平行に配置させる構成を更に周方向にも拡張して構成する実施例である。係る実施例においては、軸方向と円周方向の何れにも拡張することから、配置できる永久磁石４０及びコイル５１・５２が飛躍的にその数を増やすことが可能となり、コンパクトでコギングトルクが生じない小電力発電装置とすることが可能である。なお、図示されている円周方向に同極を示した構成は、磁気回路の数が最小公倍数４の場合である。
FIG. 8 is an explanatory diagram of an embodiment in the case where the continuous system of the continuous power generator 1 according to the present invention is extended both in the circumferential direction and in the rotation axis direction. As shown in FIG. 8, the configuration in which the straight line connecting the magnetic poles of the plurality of permanent magnets 40 rotating with the rotary shaft 10 is arranged in parallel with the rotary shaft 10 is further extended in the circumferential direction. is there. In such an embodiment, since it extends in both the axial direction and the circumferential direction, the number of permanent magnets 40 and coils 51 and 52 that can be arranged can be dramatically increased, resulting in compact and cogging torque. It is possible to have no low power generator. In addition, the structure which showed the same pole in the circumferential direction shown in figure is a case where the number of magnetic circuits is the least common multiple 4.
本発明に係る連設式発電装置１は、コアレスによるコギングトルク低減を図るとともに、多数のコイルと永久磁石４０を配置することが可能であり、大型の風力発電装置のブレードや水力発電装置の水車等のように、これらを駆動するための起動動力に大きなエネルギーを必要とせず、小さな起動動力で個々の磁気回路から発生する小さな有効電力を総合して必要な電力が供給できることから、風や水といった自然エネルギーの存在する有効な場所を選ばず、産業上の利用可能性は大きいと思慮される。
The continuous power generator 1 according to the present invention can reduce the cogging torque by coreless, and can be provided with a large number of coils and permanent magnets 40. The blades of the large wind power generator and the water turbine of the hydroelectric power generator can be provided. As described above, since a large amount of energy is not required for the starting power for driving them, and a small amount of effective power generated from individual magnetic circuits can be supplied with a small starting power, the necessary power can be supplied. Regardless of the effective location where natural energy exists, industrial applicability is considered large.
