Description

【考案の詳細な説明】[Detailed description of the invention]

【０００１】[0001]

【産業上の利用分野】[Industrial applications]

この考案は風車または水車用の直流発電機として利用できる。 This invention can be used as a DC generator for wind turbines or water turbines.

【０００２】[0002]

【従来の技術】[Prior art]

従来は風車または水車用の発電機として主に交流発電機が使用されていた。 そのためロータ８の磁極数とコイル９の個数を同期させるため整数で割り切れる 個数で組み合わせられていた。 Conventionally, an alternator has been mainly used as a generator for a windmill or a water turbine. Therefore, in order to synchronize the number of magnetic poles of the rotor 8 and the number of the coils 9, the number of the magnetic poles is combined by a number divisible by an integer.

【０００３】[0003]

【考案が解決しようとする課題点】[Issues to be solved by the invention]

風車または水車で得られる動力機械は小さな力から立ち上がることが要求さ れる。これまでの発電機では吸引力の同期によって始動トルクが大であった。こ の傾向は特に増速機を挿入したときに増大され顕著に現れていた。同時にこのこ とは一回転中の回転トルク変動が大きいことを意味し運転中の振動発生原因とも なっていた。 Powered machines obtained from windmills or watermills are required to stand up from small forces. In the conventional generator, the starting torque was large due to the synchronization of the suction force. This tendency was particularly noticeable when the gearbox was inserted. At the same time, this means that the rotation torque fluctuates during one rotation, which is a cause of vibration during operation.

【０００４】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

風車または水車の動力軸６に結合されたロータ８の極数ｎとこのロータ８の周 囲に配置されたコイル９の個数を吸引力が同期しない個数に設定する。 The number of poles n of the rotor 8 connected to the power shaft 6 of the wind turbine or the water turbine and the number of coils 9 arranged around the rotor 8 are set to numbers at which the suction force is not synchronized.

【０００５】[0005]

【作用】[Action]

このように同期しないように配置されたロータ８とコイル９をもつ発電機では 始動トルクが小さくなる。発生した電力は整流して合成することで直接バッテリ などに充電用として供給できる。各コイルの吸引力が同期しないように配置する ことで運転時の振動発生が抑制される。 The generator having the rotor 8 and the coil 9 arranged so as not to be synchronized with each other has a small starting torque. The generated power can be rectified and combined so that it can be directly supplied to a battery or the like for charging. By arranging the coils so that the attraction of each coil is not synchronized, the generation of vibration during operation is suppressed.

【考案の実施例】[Example of the invention]

図１に風力発電用のものを示す。風車は翼１、ハブ２とこれに直結される動力 軸６、増速機７および軸受３、支柱４、尾翼５によって構成されている。直流発 電機のロータ８は増速機７の出力軸に、コイル９は増速機７の本体に取り付けら れている。 コイル９に発生した電力はコイル９に接続されている整流回路から出力され合 成される。合成は動力軸６の回転数を検出し、翼の性能とコイル９やコア、磁石 など発電機の性能を考慮し回転数に応じて直列や並列に組み合わせることができ る。 FIG. 1 shows a wind turbine. The wind turbine includes a blade 1, a hub 2, a power shaft 6 directly connected to the hub 2, a gearbox 7, a bearing 3, a support 4, and a tail 5. The rotor 8 of the DC generator is mounted on the output shaft of the gearbox 7, and the coil 9 is mounted on the main body of the gearbox 7. The electric power generated in the coil 9 is output from the rectifier circuit connected to the coil 9 and is synthesized. In the synthesis, the rotation speed of the power shaft 6 is detected, and considering the performance of the blades and the performance of the generator such as the coil 9, the core, and the magnet, the combination can be performed in series or in parallel according to the rotation speed.
