Description

本発明は、ハウジング内に回転子と固定子を配置した三相交流発電機に関する。 The present invention relates to a three-phase alternator in which a rotor and a stator are arranged in a housing.

特許文献１には、ハウジング内に円筒状をなす外側固定子と内側固定子を同軸状に配置し、これら外側固定子と内側固定子との間に同軸状に回転子を配置した構造が開示されている。この特許文献１にあっては、回転子は１２個の永久磁石を磁極の向きを交互に異ならせて環状に配置し、回転子は１８個のコイルを環状に配置した構造となっている。 Patent Document 1 discloses a structure in which a cylindrical outer stator and an inner stator are arranged coaxially in a housing, and a rotor is arranged coaxially between the outer stator and the inner stator. Has been done. In Patent Document 1, the rotor has a structure in which 12 permanent magnets are arranged in an annular shape with the directions of the magnetic poles alternately different from each other, and the rotor has a structure in which 18 coils are arranged in an annular shape.

特許文献２にはモータのステータの構造が開示されている。このステータは周方向に環状に並べられた複数のコイルを備え、このコイルから伸びる引出し線を内型と外型とで挟んで屈曲させ、第１直線部及び第２直線部を成形している。この先行技術には１２個のコイルが示されており、１つのコイルが巻回された後の導線は隣接するコアに巻回されるようになっている。 Patent Document 2 discloses the structure of the stator of the motor. This stator includes a plurality of coils arranged in an annular shape in the circumferential direction, and a leader wire extending from the coils is sandwiched between an inner mold and an outer mold and bent to form a first straight line portion and a second straight line portion. .. Twelve coils are shown in this prior art, and after one coil is wound, the lead wire is wound around an adjacent core.

隣接するコアに巻かずに幾つか飛ばしたコアに巻回する場合もあるが、取り出す電圧が高くなるものではない。 It may be wound around a core that has been skipped several times without being wound around an adjacent core, but the voltage to be taken out does not increase.

特開２０１８−１０８００７号公報JP-A-2018-108007 特開２０１８−０７４８６１号公報Japanese Unexamined Patent Publication No. 2018-074861

三相交流発電機の３つの出力端子（Ｕ、Ｖ、Ｗ）から取り出す電気を大きくするには、コイルの数とコイルの巻数を多くすればよいのであるが、一定のスペース内に固定子と回転子を収める制限があるため、コイルの数及びコイルの巻数も自ずから制約がある。 In order to increase the amount of electricity extracted from the three output terminals (U, V, W) of a three-phase alternator, it is sufficient to increase the number of coils and the number of turns of the coils, but with a stator in a certain space. Since there is a limit to accommodate the rotor, the number of coils and the number of turns of the coil are also limited.

従来にあっては１本の導線の一端をＵ端子、Ｖ端子またはＷ端子に接続し、この導線を１番目のコアに巻付けて１番目のコイルとし、次いで１番目のコイルから伸びる導線を２番目のコアに巻付けて２番目のコイルとするように、隣接するコアに順次導線を巻き付け６番目のコイルから伸びる導線をニュートラル端子（星形結線の場合）に接続している。 Conventionally, one end of one lead wire is connected to the U terminal, V terminal, or W terminal, and this lead wire is wound around the first core to form the first coil, and then the lead wire extending from the first coil is used. A lead wire is sequentially wound around an adjacent core so as to be wound around the second core to form a second coil, and a lead wire extending from the sixth coil is connected to a neutral terminal (in the case of a star-shaped connection).

上記のように１つのコイルを形成した導線を隣接するコアに巻付けて次のコイルとする場合、形成される直列回路数が一定であるため、より大きな電圧を取り出すことができない。 When the lead wire having one coil formed as described above is wound around an adjacent core to form the next coil, a larger voltage cannot be taken out because the number of series circuits formed is constant.

上記課題を解決するため本発明に係る三相交流発電機は、ハウジング内に回転子と固定子が同軸状に配置され、前記回転子には前記固定子との対向面がＮ極となる磁石とＳ極となる磁石が交互に６個環状に配置され、前記固定子は６個のコイルからなるコイル群が前記各磁石に対向して配置され、各コイル群はコイル群毎に巻き方向が同じで隣接するコイル群は巻き方向が逆とされ、更に一端がＵ，Ｖ又はＷ端子に接続される導線は第１のパターンでコアに巻回され続いて第２のパターンでコアに巻回され、これ以降第２のパターンを繰り返して巻回され、前記第１のパターンは最初のコアに巻回された後に順方向に４つ飛ばした５つ目のコアに巻回され、次いで導線は順方向に５つ飛ばした６つ目のコアに巻回され、次いで導線は逆方向に４つ飛ばした５つ目のコアに戻って巻回され、また第２のパターンは前のパターンから続いて導線は順方向に５つ飛ばした６つ目のコアに巻回され、次いで導線は順方向に４つ飛ばした５つ目のコアに巻回され、次いで導線は順方向に５つ飛ばした６つ目のコアに巻回され、次いで導線は逆方向に４つ飛ばした５つ目のコアに戻って巻回される構造である。 In order to solve the above problems, in the three-phase AC generator according to the present invention, a rotor and a stator are arranged coaxially in a housing, and the rotor faces a magnet whose facing surface with the stator is N pole. And 6 magnets that become S poles are alternately arranged in an annular shape, and in the stator, a coil group consisting of 6 coils is arranged facing each magnet, and each coil group has a winding direction for each coil group. The winding direction of the same adjacent coil group is reversed, and the lead wire whose one end is connected to the U, V or W terminal is wound around the core in the first pattern and then wound around the core in the second pattern. After that, the second pattern is repeatedly wound, the first pattern is wound around the first core, and then the fifth core, which is skipped four in the forward direction, is wound, and then the lead wire is wound. It is wound around the sixth core, which has five skips in the forward direction, and then the lead wire is wound back into the fifth core, which has four skips in the reverse direction, and the second pattern continues from the previous pattern. The wire was wound around the sixth core, which was skipped five in the forward direction, then the wire was wound around the fifth core, which was skipped four in the forward direction, and then the wire was wound five in the forward direction. The structure is such that the lead wire is wound around the sixth core, and then the lead wire is wound back to the fifth core, which is skipped four times in the opposite direction.

前記コイルの総数は３６ｎ（ｎは整数）とし、またＵ、Ｖ及びＷ端子に接続されるコイル導線の本数は２本以上とすることができる。 The total number of the coils may be 36n (n is an integer), and the number of coil conductors connected to the U, V, and W terminals may be two or more.

本発明によれば、１つの端子（Ｕ，Ｖ、Ｗ）から他の端子に向かって導線をコアに巻回する際に、一部に逆方向に戻るように巻回しているため、直列回路数が増え、取り出す電圧が大きくなり、従来よりも発電効率を高めることができる。 According to the present invention, when the lead wire is wound around the core from one terminal (U, V, W) toward the other terminal, it is wound so as to partially return in the opposite direction, so that it is a series circuit. The number increases, the voltage taken out becomes large, and the power generation efficiency can be improved more than before.
