Claims

[Scope of utility model registration request]

(1) A stator frame with axial protrusions 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. An outside steam ventilation passage is formed that penetrates through the stator frame, and an inside air ventilation passage that penetrates the inside of the stator frame in the axial direction and opens radially inward at both ends of the stator frame is formed. In a rotating electrical machine, in which a bearing bracket is attached to both ends of the bearing bracket, and the rotating shaft of the rotor is rotatably supported through a bearing provided in the center of the bearing bracket, both ends of the internal air ventilation passage are open to the outside air, and the bearing bracket is attached to the bearing bracket. A rotary electric machine characterized in that a rotor is provided with a ventilation hole, a rotor is provided with a fan blade, and a windbreak plate is provided that guides cooling air sucked in by the fan blade from the ventilation hole of a bearing bracket to an internal air ventilation path.

(2) A stator coil is attached to the inner periphery of the stator core, and the coil ends extend outward from both ends of the core, and the windbreak plate surrounds the coil ends to divert cooling air around the coil ends. A rotating electric machine according to claim 1 of the utility model registration claim, characterized in that:
