ABSTRACT:
An electric rotating machine capable of lowering the temperature of a rotor disposed, wherein at least one of closed ventilation loops for cooling is formed, one of the loops constituting a ventilation passage communicating with an exhaust side through a heat source of the end of the generator to a cooler, thereby to supply cooling wind to the rotor after it passes through the cooler.
