Claims

[Scope of utility model registration request]

(1) A stator core that has axial ventilation between it and the inner circumference of the frame or within itself, and a rotor core that is fixed to the rotating shaft opposite to the stator core and has axial ventilation passages. , a rotating electrical machine comprising: a cooling fan fixed to the rotating shaft to circulate cooling air in the ventilation passage; and an air guide device provided opposite to the outer periphery of the cooling fan to force-feed cooling air in the axial direction to the ventilation passage. .

(2) The air guide device is composed of a plurality of flat plate members arranged obliquely along the circumferential direction so that the air sent out from the cooling fan is bent in the axial direction. The rotating electric machine according to item 1.

(3) The air guide device includes a plurality of flat plate members provided diagonally along the circumferential direction so that the air sent out from the cooling fan bends in the axial direction, and covers the side surfaces of the flat plate members. , and a closing plate provided on the inner circumferential portion of the frame.The rotating electrical machine according to claim 1, which is a registered utility model.

(4) The air guide device includes a plurality of flat plate members provided diagonally along the circumferential direction so that the air sent out from the cooling fan bends in the axial direction, and covers the side surfaces of the flat plate members. , and an arc-shaped closing plate provided on the inner peripheral portion of the frame.
