本発明は回転電機の冷却装置に係り、特に、双電機子形
直流機に好適な冷却装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cooling device for a rotating electric machine, and particularly to a cooling device suitable for a twin armature DC machine.
従来、一般に採用されているこの種の冷却装置は、特開
昭５２−６８９０４号公報に記載のように、大型の電動
機一台が設置される。この場合、ファンは固定子上部に
、エンドカバ一端面より軸受の方向に突出するように設
置されている。最近になり。Conventionally, this type of cooling device that has been generally employed is equipped with a single large electric motor, as described in Japanese Patent Laid-Open No. 52-68904. In this case, the fan is installed above the stator so as to protrude from one end surface of the end cover toward the bearing. Recently.

になってきた。この場合、第５図に示すように、各々の
電機子に対しファン７、ファンカバー１０、クーラー６
等により構成される冷却装置はファン７が相対向するよ
うに配置される。This type of cooling device has come to be used in twin armature motors. In this case, as shown in FIG. 5, a fan 7, a fan cover 10, a cooler 6
The cooling device is arranged such that the fans 7 face each other.

に示す。機器相互を干渉せずに取つけるためファン同士
をＬＯだけ離す必要がある。The conventional technology is adopted in a twin armature type DC machine as shown in Fig. 3, which is a transcription of the conventional technology published in Japanese Patent Application Laid-open No. 52-68904, and Fig. 4, which is a view from the ■ direction of Fig. 3. An example is shown in FIG. In order to install the devices without interfering with each other, it is necessary to separate the fans by LO.
従って、ファンガイド間寸法Ｌ＋１、電動機全長Ｌ′は
非常に長くなり、高価、かつ、電動機の据付スペースに
入らないという問題があった。Therefore, the dimension L+1 between the fan guides and the total length L' of the electric motor become very long, and there are problems in that it is expensive and does not fit in the installation space of the electric motor.
本発明の目的は電動機全長Ｌ′を短かくし据付スペース
を小さくすることにある。An object of the present invention is to shorten the total length L' of the electric motor and to reduce the installation space.
上記目的は、ファンを相互に干渉しないように千鳥形に
配置することにより達成される。The above object is achieved by arranging the fans in a staggered manner so that they do not interfere with each other.
以下１本発明の一実施例を第１図、第２図により説明す
る。第２図の第１図の■矢視図である。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. 2 is a view taken in the direction of the ■ arrow in FIG. 1; FIG.

出来る。According to this embodiment, as shown in FIG. 2, the armature fans 7 and the respective armature fans 7 are arranged in a staggered manner, and the fan covers 10.
By making the notch shape, the dimension L between the fan guides 5
X can be made shorter than L'z of the prior art, and therefore the total length of the motor can be made shorter than L' of the prior art.

ーである。In the figure, 1 is the base, 2 is the rotor, 3 is the stator, 4 is the bearing,
5 is a fan guide, 8 is an air filter, and 9 is a commutator cover.
本発明によば、電動機の全長が短かい双電機子形電動機
を製作できるので、安価で、かつ、据付スペースの小さ
い電動機を提供することが出来る。According to the present invention, it is possible to manufacture a twin armature type electric motor with a short overall length of the electric motor, so it is possible to provide an electric motor that is inexpensive and requires a small installation space.
