冷却性能が低下する。Figure 1 shows a vertical view of an open rotating electrical machine with a conventional structure.
The W4 plate end bracket 3 has an integral constriction structure as shown in the figure, so that the stator coil end 11 and the intake hole 10 of the end bracket are close to each other. This increases ventilation resistance,
Cooling performance decreases.

。As a countermeasure to this, the end bracket intake hole 10 is extended outward as much as possible to increase the distance from the stator coil end 11 to a large length L (
: L, mana, it is possible to suppress or stop the increase in ventilation resistance by widening the intake hole area, but if the intake hole area is widened,
Purring processing to ensure drip-proofness could not be adopted b
4j[l] Since the air holes are large b, there is a drawback that the drip-proof protection is inferior.

生じ易い。In addition, the air guide plate 8 is generally fixed to the outer periphery of the end bracket B by welding or the like, but the inner diameter side 13 is free as shown in the figure, so if the air guide plate is small or it is slanted. Permeability m transmitted from the stator to the housing
The air guide plate 8 itself is likely to be excited and generate vibration noise.

動音を低減した開放形回転Ｗを構成することにある。The purpose of the present invention is to make the ventilation hole of the end bracket large so that it is drip-proof and protects at the bottom, and the mounting structure increases the rigidity of the empty gIC guide plate and reduces the vibration noise caused by electromagnetic vibration. The purpose is to configure a reduced open rotation W.

Due to the fan action with the Z guide plate 8, the intake hole 10 of the end bracket and the air circulation hole 8Qt-3 provided in the air guide plate 8
At fJ, cooling air is introduced to the stator coil end 11 side, and is exhausted from the housing exhaust hole 12 while being cooled. The air guide plate 8 is shown in FIG. 3 and FIG.
a and the inner circumferential portion 8b provided on the inside are both fixed to the end bracket 3 by welding rivets or the like, so that the cross section becomes angular and the rigidity is increased. By appropriately selecting the shape and area of the air circulation hole 8C, it is possible to ensure a sufficient ventilation area and at the same time, protection.

ができる。Furthermore, the air guide plate 8 allows water droplets that enter through the end bracket intake hole 10 to be absorbed into the stator coil, and the end bracket intake hole 10 is extended outward as much as possible to increase the distance from the stator coil end 11. It is possible to reduce ventilation resistance and improve cooling performance.

なく小さくすることができる。According to the present invention, the area of the intake hole of the steel plate end bracket is increased, the intake hole is extended outward, and the distance from the stator fill end is increased to reduce ventilation resistance and improve cooling performance by 7 degrees. The structure of the air guide plate can prevent the deterioration of drip-proofness and protection, which is a problem when
The temperature rise of the rotating electric machine can be reduced without sacrificing the drip-proof screen protection.
