Claims

[Scope of utility model registration request]

The core back ventilation passage was placed on the inner circumference of the outer frame, and when the stator guide was wrapped around the stator groove, multiple ventilation holes were provided that penetrated in the axial direction. A cooling fan fixed to the rotor shaft includes a stator core, a rotor core disposed on the inner circumferential side of the stator core through a predetermined gap, and fitted to a rotor shaft. In a device for ventilation cooling of a rotating electrical machine, a ventilation hole penetrating in the axial direction is opened at the bottom of the stator groove, and the ventilation hole and the core back ventilation path are connected to each other. A ventilation cooling device for a rotating electric machine characterized by providing a communicating radial ventilation passage.
