Description
【考案の詳細な説明】
この考案は補償巻線を備えた直流機の主極鉄心に関する
。[Detailed Description of the Invention] This invention relates to a main pole iron core of a DC machine equipped with a compensation winding.
補償巻線は電機子に直列に接続されているので補償巻線
には電機子鉄心の一つのスロット内の巻線の全電流に等
しい大きさの電流がまたは整数倍の電流が流れる。Since the compensation winding is connected in series with the armature, a current equal to or an integral multiple of the total current of the winding in one slot of the armature core flows through the compensation winding.
上記のような補償巻線で電機子及作用を補償するために
、電機子鉄心のスロットのピッチに等しいかまたは整数
倍のピッチの電機子側への開口部をもつ補償スロットを
主極鉄心に設け、この補償スロットに補償巻線を設置し
ていた。In order to compensate for armature effects with the above-mentioned compensation winding, compensation slots with openings to the armature side with a pitch equal to or an integral multiple of the pitch of the slots in the armature core are installed in the main pole core. A compensation winding was installed in this compensation slot.
しかし、上記のような主極鉄心では補償スロットの電機
子側への各開口部に対し、回転する電機子鉄心のスロッ
トによる対応形状の変化が同一になるため、各開口部ご
との磁気騒音の発生の状態が一致して、大きな磁気騒音
となる欠点があった。However, in the main pole core as described above, the change in the corresponding shape due to the slot in the rotating armature core is the same for each opening of the compensation slot toward the armature, so the magnetic noise of each opening is There was a drawback that the generation conditions were the same, resulting in large magnetic noise.
この考案は上記のような欠点を除去して磁気騒音が小さ
い主極鉄心を提供することを目的とする。The purpose of this invention is to eliminate the above-mentioned drawbacks and provide a main pole core with low magnetic noise.
この考案によれば上記の目的は、補償巻線を備えた直流
機の主極鉄心において、電機子側への開口部のピッチが
不揃いな補償スロットをもっことによって達せられる。According to this invention, the above object can be achieved by providing compensation slots whose openings toward the armature have irregular pitches in the main pole iron core of a DC machine equipped with a compensation winding.
以下この考案の実施例を図面にもとづいて説明する。Examples of this invention will be described below based on the drawings.
図はこの考案の一実施例による主極鉄心を示す部分的横
断面図である。The figure is a partial cross-sectional view showing a main pole iron core according to an embodiment of this invention.
電機子１は軸（図示していない）に取付けた電機子鉄２
と、そのスロット３に配置した電機子巻線４Ａ、４Ｂ等
よりなっている。Armature 1 is armature iron 2 attached to a shaft (not shown)
and armature windings 4A, 4B, etc. arranged in the slot 3.
電機子１の外周に、継鉄５に取り付けた主極鉄心６を配
設している。A main pole iron core 6 attached to a yoke 5 is disposed around the outer periphery of the armature 1.
主極鉄心６に起磁源となる主極巻線７を取付けている。A main pole winding 7 that serves as a magnetomotive source is attached to the main pole iron core 6.
また主極鉄心６は、電機子１側への開口部８のピッチが
不揃いな補償スロット９をもっている。Further, the main pole iron core 6 has compensation slots 9 in which the pitches of the openings 8 toward the armature 1 side are irregular.
補償スロット９に補償巻線１０を設置して、電機子反作
用を補償している。A compensation winding 10 is installed in the compensation slot 9 to compensate for armature reaction.
以上述べたようにこの考案による主極鉄心は、補償巻線
を備えた直流機の主極鉄心において、電機子側への開口
部のピッチが不揃いな補償スロットをもっているので、
各開口部に対し、回転する電機子鉄心のスロットによる
対応形状の変化が不揃いとなる。As mentioned above, the main pole core of this invention has compensation slots with uneven pitches of openings toward the armature in the main pole core of a DC machine equipped with a compensation winding.
For each opening, the corresponding shape changes due to the slots of the rotating armature core become irregular.
したがって各開口部ごとの磁気騒音の発生の状態が一致
しないので、大きな磁気騒音となることがない。Therefore, since the states of magnetic noise generation for each opening are not the same, large magnetic noise does not occur.
