MOTOR STATOR ASSEMBLY AND MOTOR

WIPO Patent Application WO/2024/093547

A1

The present application relates to the field of motors, and provides a motor stator assembly and a motor. The motor stator assembly comprises a plurality of stator laminations, wherein each stator lamination is provided with a central hole and an annular outer wall, and the stator lamination is provided with a plurality of wire grooves arranged at intervals in a circumferential direction; in a radial direction, a wall surface of each wire groove close to the annular outer wall is recessed to the annular outer wall to form a cooling groove; and the stator laminations are laminated in an axial direction, the wire grooves of the stator laminations are in communication with each other in the axial direction to form a winding channel, and the cooling grooves of the stator laminations are in communication with each other in the axial direction to form a cooling channel, wherein the wall surfaces of the wire grooves forming the winding channel are flush with each other, and the wall surfaces of the cooling grooves forming the cooling channel are not flush with each other. The cooling grooves are provided and connected to form the cooling channel, so that heat dissipation can be effectively performed; and the wall surfaces of the cooling grooves are not flush with each other, so that motor harmonic waves can be effectively restrained, and motor noises are reduced.
