Title:
AXIAL FLUX MOTOR, STATOR COOLING STRUCTURE, AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/082879
Kind Code:
A1
Abstract:
The present invention provides an axial flux motor, a stator cooling structure, and a manufacturing method. The stator cooling structure comprises: a housing comprising two annular plates arranged in the radial direction; a spraying ring located between the two annular plates and connected to one of the annular plates, wherein a spraying ring oil spraying path is formed between the spraying ring and the connected annular plate, a stator cavity is formed between the spraying ring and the other annular plate, a plurality of spraying holes are formed on the spraying ring, and the spraying holes communicate the stator cavity with the spraying ring oil spraying path; and a plurality of iron core windings fixed in the stator cavity at intervals in the circumferential direction, a connection gap being formed at the joint of the spraying ring and the annular plate. The spraying ring oil spraying path is used for introducing a cooling medium, and the cooling medium is sprayed to the iron core windings in the stator cavity by means of the spraying holes on the spraying ring to achieve the cooling effect; the spraying ring oil spraying path is formed by connecting the spraying ring and the annular plate, thereby effectively reducing the machining difficulty, and ensuring the structural strength and the supporting capacity of the housing.
