しかし、こうした構成の従来の発電機において、発電能力を向上させるためにはローターの回転数を上げる必要がある。従って、その発電能力には自ずと限界がある。   However, in the conventional generator having such a configuration, it is necessary to increase the rotational speed of the rotor in order to improve the power generation capacity. Therefore, its power generation capacity is naturally limited.

本発明はこうした点に鑑み創案されたもので、ローターの回転数を上げることなく、発電能力を高めることのできる発電機を提供することを課題とする。   The present invention has been devised in view of these points, and an object of the present invention is to provide a generator capable of increasing the power generation capacity without increasing the rotational speed of the rotor.

図１乃至図６を参照して説明する。第１の発明に係る発電機１５は、外力によって回転する主軸１６と、前記主軸１６の略中間部に固定され、外周面に周方向に沿って複数の第一磁石２１を等間隔で設けた内側ローター２０と、前記内側ローター２０の外周側に、該内側ローター２０と同心状に、かつ、回転しない状態で設けられ、内周面に周方向に沿って、前記第一磁石２１と対向する複数の内側コイル束３１を固定し、外周面に周方向に沿って複数の外側コイル束３２を固定したステーター３０と、前記ステーター３０の外周側に、該ステーター３０と同心状に回転自在に設けられ、内周面の中央部に周方向に沿って、前記外側コイル束３２と対向する複数の第二磁石４１を等間隔で設け、前記内周面の一方端部に内歯車４２を設けた外側ローター４０と、前記主軸１６の一方端部に固定された太陽歯車５０と、前記太陽歯車５０と前記外側ローター４０の内歯車４２との間に設けられ、該太陽歯車５０と内歯車４２に噛み合う遊星歯車６０とで構成される。   This will be described with reference to FIGS. The generator 15 according to the first invention is fixed to a main shaft 16 rotated by an external force and a substantially intermediate portion of the main shaft 16, and a plurality of first magnets 21 are provided at equal intervals along the circumferential direction on the outer peripheral surface. The inner rotor 20 is provided on the outer peripheral side of the inner rotor 20 concentrically with the inner rotor 20 and in a non-rotating state, and faces the first magnet 21 along the circumferential direction on the inner peripheral surface. A stator 30 in which a plurality of inner coil bundles 31 are fixed and a plurality of outer coil bundles 32 are fixed along the circumferential direction on the outer peripheral surface, and provided on the outer peripheral side of the stator 30 so as to be concentric with the stator 30 and rotatably provided. A plurality of second magnets 41 facing the outer coil bundle 32 are provided at equal intervals along the circumferential direction at the center of the inner peripheral surface, and an internal gear 42 is provided at one end of the inner peripheral surface. The outer rotor 40 and the main shaft 16 A sun gear 50 fixed to one end, and a planetary gear 60 provided between the sun gear 50 and the internal gear 42 of the outer rotor 40 and meshing with the sun gear 50 and the internal gear 42. .

第２の発明に係る発電機１５は、外力によって回転する主軸１６と、前記主軸１６の略中間部に固定され、外周面に周方向に沿って複数の第一磁石２１を等間隔で設けた内側ローター２０と、前記内側ローター２０の外周側に、該内側ローター２０と同心状に、かつ、回転しない状態で設けられ、内周面に周方向に沿って、前記第一磁石２１と対向する複数の内側コイル束３１を固定し、外周面に周方向に沿って複数の外側コイル束３２を固定したステーター３０と、前記ステーター３０の外周側に、該ステーター３０と同心状に回転自在に設けられ、内周面の中央部に周方向に沿って、前記外側コイル束３２と対向する複数の第二磁石４１を等間隔で設け、前記内周面の一方端部に内歯車４２を設けた外側ローター４０と、前記主軸１６の一方端部に固定された太陽歯車５０と、前記太陽歯車５０と前記外側ローター４０の内歯車４２との間に設けられ、該太陽歯車５０と内歯車４２に噛み合う遊星歯車６０とで構成される。   The generator 15 according to the second invention is fixed to a main shaft 16 rotated by an external force and a substantially intermediate portion of the main shaft 16, and a plurality of first magnets 21 are provided on the outer peripheral surface at equal intervals along the circumferential direction. The inner rotor 20 is provided on the outer peripheral side of the inner rotor 20 concentrically with the inner rotor 20 and in a non-rotating state, and faces the first magnet 21 along the circumferential direction on the inner peripheral surface. A stator 30 in which a plurality of inner coil bundles 31 are fixed and a plurality of outer coil bundles 32 are fixed along the circumferential direction on the outer peripheral surface, and provided on the outer peripheral side of the stator 30 so as to be concentric with the stator 30 and rotatably provided. A plurality of second magnets 41 facing the outer coil bundle 32 are provided at equal intervals along the circumferential direction at the center of the inner peripheral surface, and an internal gear 42 is provided at one end of the inner peripheral surface. The outer rotor 40 and the main shaft 16 A sun gear 50 fixed to one end, and a planetary gear 60 provided between the sun gear 50 and the internal gear 42 of the outer rotor 40 and meshing with the sun gear 50 and the internal gear 42. .

また、前記ステーター３０の内周面に、前記内側コイル束３１を収納する内側凹部３３を複数形成すると共に、その外周面に、前記外側コイル束３２を収納する外側凹部３４を複数形成している。   A plurality of inner recesses 33 for accommodating the inner coil bundle 31 are formed on the inner peripheral surface of the stator 30, and a plurality of outer recesses 34 for storing the outer coil bundle 32 are formed on the outer peripheral surface thereof. .

第１の発明に係る発電機１５は、主軸１６が外力によって回転すると、それに固定されている内側ローター２０が同期して同一方向に回転する。一方、主軸１６の回転力は太陽歯車５０および遊星歯車６０を介して内歯車４２に伝達され、外側ローター４０を反対方向に回転させる。従って、内側ローター２０の第一磁石２１によってステーター３０の内側コイル束３１に電気が発生すると共に、外側ローター４０の第二磁石４１によってステーター３０の外側コイル束３２にも電気が発生する。その結果、回転数を上げることなく発電能力を高めることができる。   In the generator 15 according to the first invention, when the main shaft 16 is rotated by an external force, the inner rotor 20 fixed thereto rotates in the same direction in synchronization. On the other hand, the rotational force of the main shaft 16 is transmitted to the internal gear 42 via the sun gear 50 and the planetary gear 60, and rotates the outer rotor 40 in the opposite direction. Accordingly, electricity is generated in the inner coil bundle 31 of the stator 30 by the first magnet 21 of the inner rotor 20, and electricity is also generated in the outer coil bundle 32 of the stator 30 by the second magnet 41 of the outer rotor 40. As a result, the power generation capacity can be increased without increasing the rotational speed.

なお、内側コイル束３１および外側コイル束３２ともに回転しないステーター３０に設けられているので回転しない。そのため、仮に、ステーター３０（従って、内側コイル束３１や外側コイル束３２）が回転する場合には必要とされるスリップリングやブラシなどの出力用の部材を必要としない。従って、発電機１５の構成を簡素化することができ、経済性に優れる。また、スリップリング等を使用しないことによって、出力取出しにおける損失も少なくすることができるので、高い出力効率を発揮することができる。   The inner coil bundle 31 and the outer coil bundle 32 are not rotated because they are provided on the stator 30 that does not rotate. Therefore, if the stator 30 (therefore, the inner coil bundle 31 or the outer coil bundle 32) rotates, an output member such as a slip ring or a brush that is required is not required. Therefore, the structure of the generator 15 can be simplified and it is excellent in economical efficiency. Further, by not using a slip ring or the like, loss in output extraction can be reduced, so that high output efficiency can be exhibited.

第２の発明に係る発電機１５は、請求項１に記載の発明と同様の効果を発揮する。また、ステーター３０の内周面に内側コイル束３１を収納する内側凹部３３を形成すると共に、外周面に外側コイル束３２を収納する外側凹部３４を形成しているので、内側コイル束３１および外側コイル束３２をステーター３０の所定箇所に確実かつ強固に固定することができる。これによって、発電機１の発電能力をより確実に高めることができる。   The power generator 15 according to the second invention exhibits the same effect as that of the first invention. In addition, the inner recess 33 for accommodating the inner coil bundle 31 is formed on the inner peripheral surface of the stator 30 and the outer recess 34 for storing the outer coil bundle 32 is formed on the outer peripheral surface. The coil bundle 32 can be securely and firmly fixed to a predetermined portion of the stator 30. As a result, the power generation capacity of the generator 1 can be more reliably increased.

本発明に係る発電機１５の実施形態を、図１乃至図６に示す。この発電機１５は、自動車用の４極三相交流発電機１５であり、主軸１６、内側ローター２０、ステーター３０、外側ローター４０、太陽歯車５０および遊星歯車６０を備える（図１参照）。   An embodiment of a generator 15 according to the present invention is shown in FIGS. The generator 15 is a four-pole three-phase AC generator 15 for an automobile, and includes a main shaft 16, an inner rotor 20, a stator 30, an outer rotor 40, a sun gear 50, and a planetary gear 60 (see FIG. 1).

主軸１６は、外力（自動車エンジンの回転力）によって回転するもので、その一方側端部にプーリーＰを固定している。エンジンの回転力が、ベルトを介してこのプーリーＰに伝達され、主軸１６が回転する。なお、主軸１６の両側端部は、垂直方向に立設された一対の支持壁７０によって回転自在に支持される。   The main shaft 16 is rotated by an external force (rotational force of the automobile engine), and a pulley P is fixed to one end portion thereof. The rotational force of the engine is transmitted to the pulley P via the belt, and the main shaft 16 rotates. Note that both end portions of the main shaft 16 are rotatably supported by a pair of support walls 70 erected in the vertical direction.

内側ローター２０は非磁気性の筒状であり、主軸１６の長さ方向のほぼ中間部分に第一固定キーＫ１によって固定されている。また、内側ローター２０の外周面には、等角度間隔で母線方向に沿って複数（１８本）の棒状の第一磁石（永久磁石）２１が、半径方向外側にＮ極とＳ極が交互になるような状態で等間隔で設けられている。   The inner rotor 20 has a nonmagnetic cylindrical shape, and is fixed to a substantially intermediate portion in the length direction of the main shaft 16 by a first fixing key K1. A plurality (18) of rod-shaped first magnets (permanent magnets) 21 are arranged on the outer circumferential surface of the inner rotor 20 along the generatrix direction at equal angular intervals, and N poles and S poles are alternately arranged radially outward. In such a state, they are provided at equal intervals.

ステーター３０は、内側ローター２０の外周側に、当該内側ローター２０と同心状に、かつ、回転しない状態で設けられている。本実施形態のステーター３０は、その左右両端部が第一ベアリングＨ１を介して主軸１６に支持されており、これにより、当該ステーター３０は回転しない状態を維持する。   The stator 30 is provided on the outer peripheral side of the inner rotor 20 concentrically with the inner rotor 20 and in a non-rotating state. The stator 30 of the present embodiment is supported by the main shaft 16 at both left and right end portions thereof via the first bearing H1, thereby maintaining the stator 30 in a non-rotating state.

ステーター３０の中央部にはコイル取付部３０ａを形成し、そのコイル取付部３０ａの内周面には、周方向に沿って、第一磁石２１と対向する状態で複数（１２本）の内側コイル束３１を固定している。また、コイル取付部３０ａの外周面には、周方向に沿って複数（１２本）の外側コイル束３２を固定している（図２参照）。   A coil mounting portion 30a is formed in the center portion of the stator 30, and a plurality (12) of inner coils are arranged on the inner peripheral surface of the coil mounting portion 30a in a state facing the first magnet 21 along the circumferential direction. The bundle 31 is fixed. A plurality (12) of outer coil bundles 32 are fixed to the outer peripheral surface of the coil attachment portion 30a along the circumferential direction (see FIG. 2).

コイル束３１，３２のコイルａ１，ａ２，ａ３，ｂ１，ｂ２，ｂ３，ｃ１，ｃ２，ｃ３，Ａ１，Ａ２，Ａ３，Ｂ１，Ｂ２，Ｂ３，Ｃ１，Ｃ２，Ｃ３は、図４に示す如く、コイルａ１〜ａ２，ａ２〜ａ３，ａ３〜ａ４間が順次導線５によって接続されると共にｂ１〜ｂ２，ｂ２〜ｂ３，ｂ３〜ｂ４及びｃ１〜ｃ２，ｃ２〜ｃ３，ｃ３〜ｃ４，Ａ１〜Ａ２，Ａ２〜Ａ３，Ａ３〜Ａ４，Ｂ１〜Ｂ２，Ｂ２〜Ｂ３，Ｂ３〜Ｂ４，Ｃ１〜Ｃ２，Ｃ２〜Ｃ３，Ｃ３〜Ｃ４間が導線５によって接続され、またコイルａ１，ｂ１，ｃ１の基端はスター接続の基端連結部６で接続され、コイルａ４，ｂ４，ｃ４の末端は出力連結導線７を配して出力回路側で接続されている。同様にＡ１，Ｂ１，Ｃ１はスター接続の基端連結部６で接続され、Ａ４，Ｂ４，Ｃ４は出力連結導線７を配して出力回路側で接続されている。Coils a 1 , a 2 , a 3 , b 1 , b 2 , b 3 , c 1 , c 2 , c 3 , A 1 , A 2 , A 3 , B 1 , B 2 , B 3 , C 1 , C 2 , and C 3 are sequentially connected between the coils a 1 to a 2 , a 2 to a 3 , and a 3 to a 4 by conducting wires 5 and b 1 to b as shown in FIG. 2 , b 2 to b 3 , b 3 to b 4 and c 1 to c 2 , c 2 to c 3 , c 3 to c 4 , A 1 to A 2 , A 2 to A 3 , A 3 to A 4 , B 1 to B 2 , B 2 to B 3 , B 3 to B 4 , C 1 to C 2 , C 2 to C 3 , and C 3 to C 4 are connected by a conductive wire 5, and coils a 1 and b 1 , C 1 are connected by a star-connected base end connecting portion 6, and the ends of the coils a 4 , b 4 , c 4 are connected on the output circuit side by providing an output connecting conductor 7. Similarly, A 1 , B 1 , and C 1 are connected by a star-connected base end connecting portion 6, and A 4 , B 4 , and C 4 are connected on the output circuit side by providing an output connecting conductor 7.

外側ローター４０は非磁気性の筒状であり、ステーター３０の外周側に、当該ステーター３０と同心状に回転自在に設けられている。すなわち、外側ローター４０は、その左右両端部が第二ベアリングＨ２を介して主軸１６に回転自在に支持されている。   The outer rotor 40 has a nonmagnetic cylindrical shape, and is provided on the outer peripheral side of the stator 30 so as to be rotatable concentrically with the stator 30. That is, the left and right ends of the outer rotor 40 are rotatably supported by the main shaft 16 via the second bearing H2.

ローター２０，４０が回転すると半径方向の磁力成分（フレミングの右手の親指）を有する第一電磁石２１と第二電磁石４１の磁力線Ｙの母線方向成分（フレミングの右手の人差指）は円周の切線方向Ｘ２，Ｘ３に移動し、コイル束３１，３２の電導線の母線方向成分（フレミングの右手の中指）方向Ｚの電気を発生する。   When the rotors 20 and 40 are rotated, the generating direction component (the index finger of Fleming's right hand) of the magnetic field Y of the first electromagnet 21 and the second electromagnet 41 having the radial magnetic force component (the thumb of the right hand of Fleming) is the direction along the circumferential cut line. It moves to X2 and X3, and generates electricity in the direction Z of the conductive wire of the coil bundles 31 and 32 (the middle finger of Fleming's right hand) in the direction Z.

外側ローター４０の内周面の中央部には、周方向に沿って、外側コイル束３２と対向する状態で複数（２４本）の棒状の第二磁石４１（永久磁石）が、Ｎ極とＳ極を交互に並べた状態で等間隔で設けられている。また、外側ローター４０の内周面の一方端部には、その内周面の全周に沿って内歯車４２が設けられている。なお、第二磁石４１の形状および数は限定されない。   A plurality (24) of rod-shaped second magnets 41 (permanent magnets) are arranged in the central portion of the inner peripheral surface of the outer rotor 40 so as to face the outer coil bundle 32 along the circumferential direction. The poles are provided at equal intervals in an alternating arrangement. Further, an internal gear 42 is provided at one end portion of the inner peripheral surface of the outer rotor 40 along the entire circumference of the inner peripheral surface. The shape and number of the second magnets 41 are not limited.

太陽歯車５０は、主軸１６の一方端部に第二固定キーＫ２によって固定されており、主軸１６と同期して同一方向に回転する。   The sun gear 50 is fixed to one end portion of the main shaft 16 by the second fixed key K2, and rotates in the same direction in synchronization with the main shaft 16.

遊星歯車６０は、太陽歯車５０と外側ローター４０の内歯車４２との間に回転自在に設けられ、その太陽歯車５０と内歯車４２の双方に噛み合っている。また、この遊星歯車６０は、回転軸６１を備えており、この回転軸は支持壁７０に第三ベアリングＨ３を介して回転自在に支持されている。   The planetary gear 60 is rotatably provided between the sun gear 50 and the internal gear 42 of the outer rotor 40 and meshes with both the sun gear 50 and the internal gear 42. The planetary gear 60 includes a rotation shaft 61, and the rotation shaft is rotatably supported by the support wall 70 via a third bearing H3.

なお、本実施形態におけるステーター３０は、肉薄でリング状のケイ素鋼板を十数枚重ねて形成し、その内周面に、複数（１２本（４組））の内側コイル束３１を収納する内側凹部３３を複数形成している。本実施形態の内側凹部３３は、各組間に間隔を形成するために２４個形成されている（図４、５、６参照）。   In addition, the stator 30 in this embodiment is formed by stacking dozens of thin, ring-shaped silicon steel plates, and an inner side accommodating a plurality (12 (four sets)) of inner coil bundles 31 on the inner peripheral surface thereof. A plurality of recesses 33 are formed. Twenty-four inner concave portions 33 of the present embodiment are formed in order to form an interval between each set (see FIGS. 4, 5 and 6).

また、ステーター３０の外周面に、複数（１２本（４組））の外側コイル束３２を収納する外側凹部３４を複数形成している。この外側凹部３４は、同様の理由で２４個形成されている。なお、内側凹部３３および外側凹部３４の数は限定されない。   In addition, a plurality of outer recesses 34 for storing a plurality (12 (four sets)) of outer coil bundles 32 are formed on the outer peripheral surface of the stator 30. Twenty-four outer concave portions 34 are formed for the same reason. In addition, the number of the inner side recessed part 33 and the outer side recessed part 34 is not limited.

本実施形態に係る発電機１５は、次のように作動する。まず、自動車のエンジンを駆動すると、その回転力がベルトおよびプーリーＰ介して主軸１６に伝達され、これにより主軸１６が回転する（図３参照）。この主軸１６の回転によって、それに固定されている内側ローター２０が同期して同一方向に回転する。これによって、内側ローター２０の外周面に固定されている複数の第一磁石２１が周方向Ｘ２に沿って回転移動する。このとき、ステーター３０は回転しない状態で設けられているので、第一磁石２１の回転移動によってステーター３０の内周面に固定されている複数の内側コイル束３１に電気が発生する。   The generator 15 according to the present embodiment operates as follows. First, when the automobile engine is driven, the rotational force is transmitted to the main shaft 16 via the belt and the pulley P, thereby rotating the main shaft 16 (see FIG. 3). As the main shaft 16 rotates, the inner rotor 20 fixed thereto rotates in the same direction synchronously. Thereby, the plurality of first magnets 21 fixed to the outer peripheral surface of the inner rotor 20 rotate and move along the circumferential direction X2. At this time, since the stator 30 is provided in a non-rotating state, electricity is generated in the plurality of inner coil bundles 31 fixed to the inner peripheral surface of the stator 30 by the rotational movement of the first magnet 21.

それと同時に、主軸１６の回転によって太陽歯車５０が当該主軸１６と同期して同一方向に回転する。これに伴い、太陽歯車５０に噛み合っている遊星歯車６０が、太陽歯車５０とは逆方向に回転し、この逆方向の回転が外側ローター４０の内歯車４２に伝達され、当該外歯車が同様に逆方向に回転する。これにより、外側ローター４０の内周面に固定されている第二磁石４１が周方向に回転移動するので、これに対向位置してステーター３０の外周面に固定されている複数の外側コイル束３２に電気が発生する。   At the same time, the sun gear 50 rotates in the same direction in synchronization with the main shaft 16 by the rotation of the main shaft 16. Accordingly, the planetary gear 60 meshed with the sun gear 50 rotates in the opposite direction to the sun gear 50, and the rotation in the opposite direction is transmitted to the inner gear 42 of the outer rotor 40. Rotate in the opposite direction. As a result, the second magnet 41 fixed to the inner peripheral surface of the outer rotor 40 rotates and moves in the circumferential direction. Therefore, the plurality of outer coil bundles 32 positioned opposite to each other and fixed to the outer peripheral surface of the stator 30. Electricity is generated.

上記した作用により、内側コイル束３１と外側コイル束３２の双方に電気が発生する。従って、発電機１５の発電能力を大幅に高めることができる。   Due to the above-described action, electricity is generated in both the inner coil bundle 31 and the outer coil bundle 32. Therefore, the power generation capacity of the generator 15 can be significantly increased.

また、内側コイル束３１および外側コイル束３２ともに回転しないステーター３０に設けられているので回転しない。そのため、仮に、ステーター３０が回転する場合には必要とされるスリップリングやブラシなどの出力用の部材を必要としない。これにより、発電機１５の構成を簡素化することができるので製造コストを削減することができ、経済性に優れる。また、スリップリング等を使用しないので、出力取り出しにおける損失も少なくすることができ、これによって発電機１５の出力効率を高めることができる。   Further, since both the inner coil bundle 31 and the outer coil bundle 32 are provided on the stator 30 that does not rotate, they do not rotate. Therefore, if the stator 30 rotates, an output member such as a slip ring or a brush that is required is not required. Thereby, since the structure of the generator 15 can be simplified, manufacturing cost can be reduced and it is excellent in economical efficiency. Further, since a slip ring or the like is not used, loss in output extraction can be reduced, and thereby the output efficiency of the generator 15 can be increased.
