Cool this. Further, the cooling gas that has entered the inner diameter side of the rotor spider 2 passes through the ventilation duct 4 and flows between adjacent field coils 11 as shown by the arrows, thereby cooling the coils.

Since the rotor of a conventional rotating electric machine is configured as described above, the cooling gas flowing between the magnetic poles 9 and into the air gap has the same peripheral speed (same angular velocity) as the magnetic poles 9 due to the fan action of the magnetic poles 9. given,
It is ejected into the air gap 20 with this circumferential velocity (angular velocity), and is ejected into the air gap 20 with a large angular momentum.

9, the cooling gas is converted into a flow only in the radial direction by the ventilation duct 15 provided in the radial direction, so that the angular velocity of the cooling gas in the air gap 20 becomes zero. becomes. Therefore, a large amount of angular momentum in the air gap 20 is wasted in changing this flow,
This resulted in a loss of ventilation power almost directly, and the problem was that sufficient efficiency could not be obtained.

Hereinafter, the configuration of a rotor of a rotating electric machine according to an embodiment of this invention will be explained based on the drawings. In FIGS. 3 to 6, numerals 1 to 20 are the same as the conventional device described above. Reference numeral 21 denotes a guide cover that is disposed at the end of the magnetic pole head of the adjacent magnetic pole 9 in the opposite direction to the rotating direction, and forms an ejection path 22 between the magnetic pole head of the other magnetic pole 9, and is approximately aligned with the axis of the magnetic pole 9. The rotor 1 is provided along the entire length of the magnetic pole core 10 along with the outer peripheral surface of the magnetic pole core 10.
8, and throttles the outlet of the cooling air that has passed between the magnetic poles 9 toward the air gap 20. When the cooling air is ejected from the ejection passage 22 to the air gap 20, it is ejected in the opposite direction to the rotational direction of the rotor 18. is configured to do so. 23 is a magnetic pole 9 in order to prevent the cooling gas that has flowed between the magnetic poles 9 from the ventilation duct 4 provided in the rim 3 from flowing out from above and below the magnetic poles 9.
This is a seal plate provided in between. Reference numeral 24 is a fixing member that is implanted in the rim 3 and that pulls the guide cover 21 toward the rim 3 and fixes it so that it will not loosen even if a centrifugal force is applied, and is composed of, for example, a bolt 24a and a nut 24b.

定子鉄心１４を冷却する。また、フアン１２によ
る冷却気体の流通は上記従来装置と同様である。 In the above configuration, due to the rotation of the rotor 18,
As in the conventional case, the cooling gas that has entered the inner diameter side of the rotor spider 2 passes through the ventilation duct 4 and flows between adjacent field coils 11 to cool them. The outlet of the cooling gas passing between the magnetic poles 9 to the air gap 20 side is narrowed by the guide cover 11, the wind speed is increased, and the fan action of the salient poles is added, resulting in an ejection path 22 between the head of the magnetic pole core 10 and the guide cover 21. The air is ejected from the air gap 20 in a direction opposite to the direction of rotation of the rotor 18 at a speed of about 1/2 to 1/3 of the circumferential speed. The cooling gas that has passed through the air gap 20 passes through the ventilation duct 15 of the stator 19 and cools the stator coil 16 and the stator core 14. Further, the circulation of cooling gas by the fan 12 is the same as in the conventional device described above.
このようにすることによつて通風動力損が小さ
くなる原理を回転子１８の周速度と冷却気体の速
度関係を示した第５図の速度三角形で説明する。 The principle by which the ventilation power loss is reduced by doing this will be explained using the speed triangle in FIG. 5, which shows the relationship between the circumferential speed of the rotor 18 and the speed of the cooling gas.
この速度三角形でわかるように、磁極９出口部
分での冷却気体の絶対速度v1は磁極９の周速ｕと
磁極に対する冷却気体の相対速度w1を合成した
形で決まる。ここでｖはv1，v2にｗはw1，w2に
対応する。従来の装置では、磁極９間を通る冷却
気体は磁極９のフアン作用により磁極９とほぼ同
一の周速を与えられるため、磁極９に対する冷却
気体の相対速度w1はほぼ外向きになり相対速度
w1が磁極間中心線外向と成す角度β1は0゜に接近す
る。これにより冷却気体の絶対速度v1の周速成分
u1は回転子１８の周速ｕに近くなる。これに対し
て、この考案では磁極頭部にガイドカバー２１が
取付けられ、このガイドカバー２１によつて冷却
気体の噴出方向が回転方向と逆方向に向けられ
る。このため冷却気体の磁極９に対する相対速度
w2は、磁極間中心線外向に対して、周速と反対
方向に大きく傾く（角度β2）ことになる。これに
より冷却気体の絶対速度v2の周速成分u2は回転子
１８の周速ｕよりかなり小さくでき、通風量が同
一の場合、通風動力はエアギヤツプ２０に噴出す
る冷却気体の絶対速度の周速成分に比例するため
u2／u1倍に小さくなる。 As can be seen from this velocity triangle, the absolute velocity v 1 of the cooling gas at the exit portion of the magnetic pole 9 is determined by the combination of the circumferential velocity u of the magnetic pole 9 and the relative velocity w 1 of the cooling gas with respect to the magnetic pole. Here, v corresponds to v 1 and v 2 and w corresponds to w 1 and w 2 . In the conventional device, the cooling gas passing between the magnetic poles 9 is given almost the same circumferential speed as the magnetic poles 9 due to the fan action of the magnetic poles 9, so the relative velocity w 1 of the cooling gas with respect to the magnetic poles 9 is almost outward, and the relative velocity is
The angle β 1 that w 1 forms with the outward direction of the center line between the magnetic poles approaches 0°. As a result, the circumferential velocity component of the absolute velocity v 1 of the cooling gas
u 1 becomes close to the circumferential speed u of the rotor 18. In contrast, in this invention, a guide cover 21 is attached to the magnetic pole head, and the guide cover 21 directs the jetting direction of the cooling gas in a direction opposite to the rotation direction. Therefore, the relative velocity of the cooling gas to the magnetic pole 9 is
w 2 is largely inclined (angle β 2 ) in the direction opposite to the circumferential speed with respect to the outward direction of the center line between the magnetic poles. As a result, the circumferential velocity component u 2 of the absolute velocity v 2 of the cooling gas can be made considerably smaller than the circumferential velocity u of the rotor 18, and when the amount of ventilation is the same, the ventilation power is the circumference of the absolute velocity of the cooling gas jetted into the air gap 20. Because it is proportional to the velocity component
u 2 /u becomes 1 times smaller.
すなわち、エアギヤツプ２０に噴出する冷却気
体の絶対速度の周速成分が小さくなることによつ
て角運動量が小さくなつて、通風動力損が小さく
なる。 That is, as the circumferential velocity component of the absolute velocity of the cooling gas ejected into the air gap 20 becomes smaller, the angular momentum becomes smaller, and the ventilation power loss becomes smaller.
このように隣接する磁極９間からエアギヤツプ
２０に噴出する冷却気体は、ガイドカバー２１に

子１８の周速よりかなり小さくなるため、この部
分で冷却気体が有する角運動量も小さくなる。従
つて、これがエアギヤツプ２０で消滅することに
よつて、生じる通風動力損が小さくなる。 In this way, the cooling gas ejected from between the adjacent magnetic poles 9 into the air gap 20 is ejected in the opposite direction to the rotational direction by the guide cover 21, so that the circumferential velocity (angular velocity) of the cooling gas at the ejection part is Since the circumferential speed of the child 18 is considerably lower than that of the child 18, the angular momentum of the cooling gas in this portion is also small. Therefore, by eliminating this in the air gap 20, the ventilation power loss that occurs is reduced.

As explained above, this idea includes a guide cover that is fixed to the head of one of the adjacent magnetic poles and forms a blowout path between the head of the other magnetic pole, and the cooling gas that blows out from between the magnetic poles into the air gap. The outlet to the air gap side is throttled and the cooling gas is ejected from the blowout path to the air gap in the opposite direction to the rotational direction of the rotor, and a fixing member is provided on the rotor rim to pull and fix the guide cover toward the rim, so the guide cover is fixed. does not loosen even when centrifugal force is applied,
Moreover, ventilation power loss can be reduced and sufficient efficiency can be obtained.
