本発明は、船舶エンジンの磁石式発電機の発電出力を上
げても、磁石式発電機自身の回転変動を小さくし、船舶
エンジンの回転安定性を向上することに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention reduces rotational fluctuations of the magnetic generator itself even if the power generation output of the magnetic generator of the marine engine is increased, thereby stabilizing the rotation of the marine engine. Concerning improving sexuality.
従来の船舶エンジンの回転変動を小さくする方法として
特公昭６２−１３５１１号記載のように、エンジン側の
点火時期を制御することが主であり、エンジンのクラン
ク軸に回転子が嵌合される磁石式発電機自身の回転変動
については配慮されていなかったため、従来技術の単相
発電方式のままでは、発電機の高出力化に伴ない、発電
コイルを流れる交番電流によって発生する、交番磁束も
大きくなり、エンジン回転安定性が悪化するという欠点
があった。As described in Japanese Patent Publication No. 62-13511, the main method for reducing rotational fluctuations in conventional marine engines is to control the ignition timing on the engine side. Since no consideration was given to the rotational fluctuations of the generator itself, if the conventional single-phase power generation method was used, the alternating magnetic flux generated by the alternating current flowing through the generator coil would increase as the generator output increased. This has the disadvantage that engine rotational stability deteriorates.
上記従来技術は、発電機の高出力化に伴ない、該発電機
の回転変動は大きくなり、エンジンのクランク軸に嵌合
されている回転子の回転変動が、船舶エンジンの回転安
定性を悪くする点について配慮がされておらず、高出力
化に伴ないエンジン回転安定性が悪化するという問題が
あった。In the above conventional technology, as the output of the generator increases, the rotational fluctuation of the generator increases, and the rotational fluctuation of the rotor fitted to the engine crankshaft worsens the rotational stability of the marine engine. However, there was a problem in that the stability of engine rotation deteriorated as output increased.
本発明の目的は、エンジン回転安定性を悪化させること
なく、発電出力を上げることにある。An object of the present invention is to increase power generation output without deteriorating engine rotational stability.
上記目的を達成するために、三相発電方式にしたもので
ある。In order to achieve the above objectives, a three-phase power generation system was adopted.
回転子が回転すると、固定子鉄心に巻かれたコイルに交
流電流が発生するが同時に該交流電流により、該固定子
鉄心に交番磁束が発生する。When the rotor rotates, an alternating current is generated in a coil wound around the stator core, and at the same time, an alternating magnetic flux is generated in the stator core due to the alternating current.
該交番磁束が強いと、回転子の回転変動は大きくなるが
、三相発電機の場合は、−相当りの交流電流が小さくと
も、高出力を得ることができる。If the alternating magnetic flux is strong, the rotational fluctuation of the rotor becomes large, but in the case of a three-phase generator, high output can be obtained even if the alternating current is small.
また、各相のコイルを巻数を同じにすることにより、各
相コイルに発生する交番磁束を互いに打ち消すようにも
できるので、エンジンの回転安定性を悪化させることな
く、高出力化できる。Further, by making the coils of each phase have the same number of turns, the alternating magnetic flux generated in the coils of each phase can be canceled out, so that high output can be achieved without deteriorating the rotational stability of the engine.
以下、本発明の一実施例を第１〜４図により説明する。 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

ｃには交流電流４ａ、４ｂ、４ｃが発生する。該交流電
流４は、整流器５で整流され、出力電流６が取り出され
る。When the rotor 2 fitted to the marine engine crankshaft of the three-phase generator 1 rotates, the power generation coils 3a, 3b, 3 of each phase are rotated.
AC currents 4a, 4b, and 4c are generated at c. The alternating current 4 is rectified by a rectifier 5, and an output current 6 is taken out.
一方、該発電コイル３ａ、３ｂ、３ｃには、該交流電流
４ａ、４ｂ、４ｃにより、交番磁束７ａ。On the other hand, alternating magnetic flux 7a is generated in the generator coils 3a, 3b, 3c by the alternating currents 4a, 4b, 4c.
７ｂ、７ｃが発生し、該回転子２の回転を変動させる力
が働く。7b and 7c are generated, and a force that changes the rotation of the rotor 2 acts.
しかし、該発電コイル３ａ、３ｂ、３ｃの巻数は、同じ
に巻かれているので、該交番磁束７ａ。However, since the number of turns of the generator coils 3a, 3b, and 3c is the same, the alternating magnetic flux 7a.
７ｂ、７ｃは互いに打ち消し合うので該回転子２の回転
変動をさせる力は働かない。7b and 7c cancel each other out, so that no force is exerted to cause the rotation of the rotor 2 to fluctuate.
本実施例によれば、エンジン回転安定性を悪くする、発
電電流による交番磁束を少なくすることができるので、
高出力化に伴なうエンジン回転安定性の悪化を防止する
ことができる。According to this embodiment, it is possible to reduce the alternating magnetic flux caused by the generated current, which deteriorates the engine rotational stability.
It is possible to prevent deterioration of engine rotational stability due to higher output.
