Claims

[Scope of claim for utility model registration] A rotating shaft and a rotor core, a stator core provided on the outer circumference of the rotor core, a frame provided on the outer circumference of the stator core, and a stator core and the frame. and a ventilation passage formed between the stator core and the stator core, the stator core being constituted by a laminate of a plurality of steel plates each having a predetermined relative displacement in the circumferential direction. The cooling airflow directed in the axial direction of the stator core is placed in the ventilation passage.
A stator cooling structure for a rotating electrical machine characterized by having a wind guide plate oriented in a direction that gradually narrows a flow path.
