DISC-TYPE ELECTRIC MOTOR, STATOR, AND COOLING PIPELINE FOR INTERTOOTH COOLING OF AXIAL MAGNETIC FIELD ELECTRIC MOTOR STATOR

WIPO Patent Application WO/2022/027934

A1

Disclosed are a disc-type electric motor, a stator and a cooling pipeline for intertooth cooling of an axial magnetic field electric motor stator. The cooling pipeline comprises a pipeline body (7). The pipeline body comprises a plurality of annular protruding portions (8), the plurality of annular protruding portions are evenly arranged around the same circle center at equal included angles, a flow channel inlet (5) is fixed to one end of the pipeline body, a flow channel outlet (6) is fixed to the other end of the pipeline body, and the pipeline body is formed by an upper sheet body (4), an outer side sheet (3), a lower sheet body (1) and an inner side sheet body (2) in a surrounding manner. The cooling pipeline for intertooth cooling of an axial magnetic field electric motor stator is formed by sequentially connecting the four sheet bodies in a surrounding manner, each sheet body is in the shape of a cooling space, and on any cross section, the cooling pipeline is formed by sequentially connecting the four sheet bodies in a surrounding manner, such that the production process is simplified, the manufacturing cost is reduced, and the production efficiency is improved.
