Claims

[Scope of utility model registration request]

A cylindrical stator frame in which axial protrusions are formed by bending a plate made of a good thermal conductor in a corrugated manner is fitted onto the outer peripheral surface of the cylindrical stator core. In a rotating electric machine, in which an outside air ventilation passage is formed that penetrates through the stator frame, and an inside air ventilation passage that penetrates inside the stator frame in the axial direction is formed, U-shaped axial grooves are formed radially on the outer periphery of the stator core. A rotating electric machine characterized in that the inner peripheral side of the protrusion of the stator frame is joined to the axial groove.
