Description
【０００１】0001
本考案は回転電機の固定子の構造に関し、特に大型回転電機の固定子の固有振 動数を調整する場合に適用して有用なものである。 This invention relates to the structure of the stator of a rotating electrical machine, and in particular to the natural vibration of the stator of a large rotating electrical machine. This is useful when adjusting the number of movements.
【０００２】0002
回転電機、特に大型回転電機の固定子の円環振動の固有振動数は高次のモード において、電源周波数の２倍近くになることがあり、このため電源周波数との共 振の可能性をもっている。そこで、従来技術においては、回転電機の設計に際し 、ＣＡＥ解析で固定子が共振しないように配慮している。 The natural frequency of the annular vibration of the stator of rotating electric machines, especially large rotating electric machines, is a high-order mode. The power frequency may be nearly twice as high as the power supply frequency, so It has the potential to swing. Therefore, in the conventional technology, when designing rotating electric machines, , CAE analysis takes care to prevent the stator from resonating.
【０００３】0003
従来技術における大型回転電機では、設計時点で、上述の如き固定子の共振防 止の手段を講じているが、電源周波数と共振する可能性があるモードは高次のモ ードであるため、計算精度にも限度がある。 In conventional large-scale rotating electric machines, the above-mentioned stator resonance prevention is required at the design stage. However, the mode that may resonate with the power frequency is a higher-order mode. Since it is a code, there is a limit to the calculation accuracy.
【０００４】 このため、回転電機の固定子の固有振動数が電源周波数の共振域にある場合に は、剛性を変えるため、固定子のフレームに補強部材を追加溶接したり、逆に切 欠きを形成して対応している。このため、前述の如き追加溶接及び切欠きの形成 に多大な作業時間を要するという問題がある。0004 For this reason, when the natural frequency of the stator of a rotating electrical machine is in the resonance region of the power supply frequency, In order to change the rigidity, reinforcing members are additionally welded to the stator frame, or conversely, reinforcing members are cut. We respond by forming gaps. For this reason, additional welding and notch formation as described above There is a problem in that it requires a large amount of work time.
【０００５】 本考案は、上記従来技術に鑑み、簡単に固有振動数を調整することができる回 転電機の固定子の構造を提供することを目的とする。[0005] In view of the above-mentioned conventional technology, the present invention is a circuit that can easily adjust the natural frequency. The purpose is to provide a stator structure for a converting machine.
【０００６】[0006]
上記目的を達成する本考案の構成は、 The structure of the present invention to achieve the above purpose is as follows:
【０００７】 回転電機の回転軸の中心を中心とする円の一部である円弧状のスリットを、前 記固定子のフレームの端板に形成するとともに、このスリットに挿入する駒によ り固定子の固有振動数を調整するようにしたことを特徴とする。[0007] An arc-shaped slit, which is a part of a circle centered on the center of the rotation axis of the rotating electric machine, is This is formed on the end plate of the stator frame, and the piece inserted into this slit It is characterized in that the natural frequency of the stator is adjusted.
【０００８】[0008]
上記構成の本考案によれば、スリットに挿入する駒の大きさを調整することに より実質的なスリットの長さを適宜調整する。 According to the present invention having the above configuration, the size of the piece inserted into the slit can be adjusted. Adjust the length of the more substantial slit as appropriate.
【０００９】[0009]
以下本考案の実施例を図面に基づき詳細に説明する。 Embodiments of the present invention will be described in detail below based on the drawings.
【００１０】 図１に示すように、回転電機の固定子１のフレームの端板１ａには、この回転 電機の回転軸の中心を中心とする円の一部である円弧状の４個のスリット２ａ， ２ｂ，２ｃ，２ｄを形成している。各スリット２ａ，２ｂ，２ｃ，２ｄには駒３ ａ，３ｂ，３ｃ，３ｄを挿入して端板１ａに溶着してある。かくして、このとき の駒３ａ〜３ｄの大きさを調整することにより実質的なスリット２ａ〜２ｄの大 きさを調整して固定子１の固有振動数を調整している。0010 As shown in Fig. 1, the end plate 1a of the frame of the stator 1 of the rotating electrical machine has a four arc-shaped slits 2a that are part of a circle centered on the center of the rotating shaft of the electric machine; 2b, 2c, and 2d are formed. Each slit 2a, 2b, 2c, 2d has 3 pieces. a, 3b, 3c, and 3d are inserted and welded to the end plate 1a. Thus, at this time By adjusting the size of the pieces 3a to 3d, the actual size of the slits 2a to 2d can be adjusted. The natural frequency of the stator 1 is adjusted by adjusting the pitch.
【００１１】 かかる実施例によれば駒の大きさを選択することにより固定子１の固有振動数 を適宜選定することができる。[0011] According to this embodiment, the natural frequency of the stator 1 can be adjusted by selecting the size of the pieces. can be selected as appropriate.
【００１２】0012
以上実施例とともに具体的に説明したように、本考案によれば固定子の固有振 動数を容易に調整することができるので、電源周波数との共振を容易に回避する ことができる。このとき、駒は小さいので、固着のための溶接量は極めて小さく 、作業性も良好なものとなる。 As specifically explained above with the embodiments, according to the present invention, the natural vibration of the stator is The frequency can be easily adjusted to easily avoid resonance with the power supply frequency. be able to. At this time, since the pieces are small, the amount of welding required for fixation is extremely small. , the workability is also good.
