Cooled air passing through the cooler C) 6) guides J[n of the claw plate (311) and the upper The internal air passage (1) formed between the outer jacket (7) of the rotor and the rotor spider (10) circulates within the rotor spider (10). In this case, the air cooled by 3y1 from the cooler ~0 is structured so that it does not circulate from within the rotor spider (IIII) toward the lower part of the rotor (1) and stator (6), and the air is The somewhat warm air that has come out in step A) is sucked out from the gap between the lower ventilation guide plate c(1) and the rotor (1) The rotor spider (
10) is sucked into the rotor spider (10). These air differences are indicated by arrows in Figure 1. If the air that enters from this ventilation hole (1) is low temperature, it is good because it cools the bracket arm (5), but when the output becomes high and the temperature becomes high, the high temperature air heats the bracket arm (5). The bracket arm (5) expands thermally, causing the position of the bracket arm (!, (r,) supported by the bracket arm, !, (r,) to shift by 4 degrees), and the bracket arm, (5) to The source of vibration could be caused by misalignment of the attachment part to the wall (9).
