[Scope of Claim for Utility Model Registration] 1. In a rotating electric machine equipped with a detector for detecting the rotational speed or position of a rotating shaft, a partition air guiding ring forming a ventilation chamber within the machine frame, and a ventilation system in the machine frame. A ventilation port consisting of an intake port and an exhaust port placed on the part facing the chamber, a ventilation duct extending axially inside the rotor, and a ventilation duct that closely fits the rotor short-circuit ring and forms a narrow gap with the partition air guide ring. A balance disk fixed to the rotating shaft seals the outside air, a ventilation hole that passes through the balance disk in the axial direction to connect the ventilation chamber and the rotor's ventilation duct, and a ventilation hole that is installed inside the ventilation chamber to generate ventilation in the circumferential direction. an axial duct opening in at least one of the rotating shafts and extending axially within the rotating shaft of the detector mounting part; and a ventilation hole communicating the axial duct with the inner circumference of the fan blade. A cooling device for a rotating electric machine, characterized by having the following. 2. A cooling device for a rotating electric machine according to claim 1, which is provided with a fan blade that is fixed to at least one of the balance disks. 3. The cooling device for a rotating electrical machine according to claim 1 of the utility model registration claim, wherein the partition air guide ring is provided with fins as a means for increasing the heat transfer area. 4. A cooling device for a rotating electric machine according to claim 1, wherein a shroud is attached to the outer end of the fan blade, and the inner periphery of the shroud is fitted and fixed to the rotating shaft. 5. A cooling device for a rotating electrical machine according to claim 1, wherein a ventilation duct is passed through the rotating shaft in the axial direction. 6. The cooling device for a rotating electrical machine according to claim 1, wherein a detector for detecting the rotational speed or position of the rotating shaft is disposed inside the rotating electrical machine from a bearing that supports the rotating shaft. 7. A cooling device for a rotating electrical machine according to claim 1 of the utility model registration, in which the balance disk and fan blade are separated, and the distance between the rotating shaft bearing and the fan blade is shortened. 8. A cooling device for a rotating electric machine according to claim 1 of the utility model registration, in which a fan blade is provided on a rotor end ring.
