Claims

[Scope of utility model registration request]

In a structure in which the inside of the rotating electric machine is cooled by blowing outside air into the rotating electric machine from one end in the axial direction to the other end, the outside air is cooled inside the rotating electric machine separately from the cooling air passing through the inside of the rotating electric machine. 1. A ventilation-cooled rotating electric machine device comprising a bearing cooling ventilation passage that sucks and conducts air directly into the vicinity of a leeward side bearing and discharges the air by the rotation of a fan driven by a rotor. −
